- Hey Everyone!
This video is a quick walkthrough of a very basic Substation. Most subs now have much more advanced equipment! None the less, all of the equipment is tested regularly and just as reliable in terms of delivering power to the customers. In fact often times, substation related problems are fewer and far between not having to deal with all the fancy equipment! I'd still much rather operate a breaker remotely then mess around with a high tension fuse.
Be safe Everyone. Cheers! 🥂

Hey Everyone! This isn't what I would consider "a fine example" of a substation 😨... It's about as basic as they come, but it works! New subs follow the same basic principles but with much fancier equipment. The biggest down fall is not being able to remotely operate the equipment or retrieve electronic readings for fault data. The pros?? It's like working on an old car! Reliable and easy to maintain. 😁😏
Have a great week all! 🍻👊
The life of the paper is the life of the Transformer👈
Ain’t that the truth. It’s a bit scary to think about how fragile our infrastructure really is being all electronically controlled. Not just electricity, all other utilities and energy sources. While it is much more efficient and easy the electronic way, it’s hard to beat old school solid state mechanical equipment. Thanks for taking us along Aaron. Hope all is well on the home front!
Thanks Mike! All is well here 🙏. Hoping you and the family are doing well as well!
@@Bobsdecline Can’t complain man.
You made me dizzy.. Great video. If I hear a giant boom during a lightning storm and the ground rumbles is that the lightning arrester protecting the transformer? The lights may flicker but don’t cut out. I have learned so much from you. I watch almost every video and I’m 41 so my parents had there own conclusions.
Always impressed by the level of professionalism shown by you, and your company. Your electricity customers are very fortunate to have you.
The algorithm is so wierd! Today at lineman College we were literally talking about all the different equipment found in a substation. Thanks for sharing 👍 😃
Glad you went in there instead of me. People never think about how complicated things are .
Thanks for showing us that Aaron. I used to work for a firm that provided telemetry equipment to the main grid provider here in the UK, and occasionally had to visit substations to deliver equipment. Those were 400/275 kV, with sounders to warn of impending switching operations.
Wouldn't the 50hz power hum do the trick?
Back in the early 70s we moved a steel substation to a new location in winter. Cold. -25F some days. Work 20 minutes then in the truck. Thx for the walk through.
That's getting pretty chilly! Hard to do anything really! All the tools are frozen solid and steel work boots don't help 😟
Here's 173 KV of appreciation for all you do. We.really like your program. You give great face to what goes on behind-the-scenes. We all see the wires running around us, but few of us have any idea what they do.
It's great to see you explain it so we understand it.
We're Coming to you from the lovely Santa Cruz mountains, 40 miles south of San Francisco.
Being up in the mountains power is never taken for granted. We have storms throughout the year that cause the lights to flicker and the power to go out for several days at a time. It just takes one person failing 🎉to trim the trees on their property and it takes it down for everybody.
Again, thank you for everything you do and please, please stay safe...
Watching from the suburban Chicago area. I'm not a lineman, but I am an electrical engineer so I understand most of what is going on. Cool stuff!
Fist bumps from Florida. Really appreciate you redoing the recording after seeing you wouldn't watch it yourself
👊 Aaron, retired electrician here is St.Louis, Missouri enjoying all the videos. Interesting, educational, informational, keep up the great work for your subscribers and your community. Stay safe !!!
Question, is 16 an hour with no insurance and no chance of raises until a year something that's normal for an apprentice electrician? I made 10/hour more as a biomed in Oregon but due to their whack covid policies I lost my job and had to start at the bottom. My coworker walked off the job because he said 16 an hour and no insurance is a no go for him. Am I just cheap labor? Boss said there is no raise money, but showed up to work last week with a brand new $70k truck. And he keeps getting us shit jobs...for instance his brother's house. Or his house. He's also a polygamist
@@Al_Gore_Rhythmn considering I started at 17/hr in Nevada where the minimum wage is 8 bucks I'd say your just cheap labor. Isn't the minimum wage in Oregon like 13 bucks
@@omarbojorquez7826 I was making 25 in Oregon plus Hella overtime and paid for my miles. In Utah, I'm making 16 an hour as an apprentice electrician. When did you start?
@@Al_Gore_Rhythmn I started last year, now im making 21/hr with free gas
@@Al_Gore_Rhythmn last year January
Here in Jamaica, we also use 69kv transmission (a few 138kv subs) stepped down to 24kv distros (a few 13kv here and there). I work in the telecoms department for our power company.
So that is what a God of our modern electrified civilization looks like? Thank you sir!
Your depth of knowledge is humbling.. I wish I was smart enough to grasp what you were talking about.
Great video Aaron. I did one of my engineering internships with NL Power and my cousin works with you guys based in Truro. Watching from Houston TX - where our major loads are in the summer from air conditioning. Almost all pole-mounted transformers are finned for heat dissipation. Most home heating in the winter is with natural gas.
use to live In texas as big as houston is Im surprised they use a coal fired plant. I remember living in Missiouri city as a kid and my dad driving to work in Rosenberg and It was cool seeing the steam coming from the stacks of WA parish early in the morning
@Andrew Quinlan How do you feel about the powers that be (pun intended). Since Ercot is closed to the rest of the United States. Do you feel that the loss of redundancy makes function more difficult? Reliability is really important from my perspective; Would the interests of the public be served better by integration as opposed to Self-Reliance?
North Korea has a similar policy called, “Juche”
Right before I retired , a new trouble man closed the wrong air circuit breakers on the 69kv sub , nice light show ...... no one hurt but WOW.............. be safe and double check everything ! we have 230kv , 138 kv and 69kv transmission substations ..... down in San Diego we also have a 500kv line coming in from Arizona Huge substation too Alan Thomas
Thanks for the detailed walkthrough, I find these really interesting to compare how countries operate their substations. Appreciate your really clear explanations.
Great videos keep up the good work.
Great video. I dont know any of the sub station equipment but I work out on the transmission lines. 2 years ago we had the utility close the line back in on us without any notice. Our master grounds were still up and guys were working on the line.
Yikes!!
@@generatorjohn4537 I didn't see it but I guess they said it blew our ground rod right out of the ground. It wasn't the first time they've done stuff like that to us and it won't be the last.
Oh man, that's scary 😔
@@mfk12340 When I worked in the substations years ago I was on the switching and tagging list. In other words I was sometimes in charge of projects while working inside the substations. All work that was performed was usually done in a de-energized state. Once the work was completed it was checked, tested, functionally checked, etc. Once all work was completed we would remove "our" workman's grounds if that was necessary for the particular project and then cancel the clearance. (A clearance is permission to perform work that is granted by the operating authority within electrical transmission system) These projects are planned weeks, months in advance BTW.
When we officially cancel the clearance, the work is all complete, no more work can be performed, and it's ready to return to normal service. We also declare that men and equipment are cleared and All Workman's Grounds are Removed!
How this can happen in your case is beyond me.
Sorry for the long explanation but someone is not following the safety procedures and if this happens again those responsible should be reported and sorry to say, fired!
@@generatorjohn4537 that's what's supposed to happen in our case too. And eversource never gave us a reason or explanation to what happened. At least for linehands. We had our master grounds one on like str # 180 and the other on str # 100ish. And eversource had been a pita with the 24 hour recall notice because it was one of the one of two lines going into this smaller substation. And somewhere somehow the chain of communications broke down and the re-energized the line with all our equipment still on it. Nobody was happy.
They also did the same thing to our drillers, they had a couple underground line strikes, digsafe didn't mark them, and eversource came out and threw the fuses back in and re-energized the underground without riding it. Nearly fried the operator who was still in the machine.
Also on our digsafes we did an audit on their reports. From the time we submitted a request from digsafe to when they said they went out and said it was clear was 13 minutes. They didn't even check if there were any utilities in the area.
Love your content my dude, Im a network engineer currently for Oneok in tulsa and were a natural gas provider, one of the largest in the midwest. Watching your work and the excitement but also the importance of intelligence has kinda pushed me to start taking classes and maybe make a career change. Ya the IT stuff is cool and all, but man this stuff really gets the gears going.
I just started on the engineering side things in the PNW, state side. Your videos are awesome I helping me understand from a lineman perspective.
Thanks Jonathan!
Watching this in Oklahoma here in the middle of July right now and I got to say the coolest part of your video has the be the snow. We’re baking out here in a heat wave (it’s been over 100*F almost daily and tomorrow’s supposed to be 111*F) and sure glad folks like you keep the power on so when I eventually get to the house, I can grab a cold one out of the fridge and stand in front of the ice cold AC vents and cool down before heading outside the next day.
Great videos to watch during my break time.
Thanks to all you Lineman for leaving some work for us Wireman. You are all under appreciated in my opinion. Shout out from Southern Nevada.
👊 West Virginia, USA. Not in the trade myself but I’m fascinated by it and love learning about it. Always enjoy your videos, appreciate the work you put into making them and the work you and all others do to keep the lights on!
Cheers and thanks for your channel! I'm 35 and wishing I would have looked into lineman / electrician more when I was young! (from Oklahoma City)
I started as a substation maint tech at 45. 35 is not to old. Do it, never too old.
👊from San Diego. I recently entered my first substation as a consultant on a pice of equipment with the utilty. It was even more facinating than I expected. I enjoyed trying to identify the various components and even correctly answered a question that the manager gave to his team on one of the components. The substation I was in was substantially larger with multiple power transformers. It would be cool to see your tour of a larger substation. I appreciate your perspective as it has helped me in my career a lot. Thank you
Watching you from Thornville Ohio USA 🇺🇸
Thank you for keep Us informed.

Much Respect Sir...NJ IBEW!!
Love those glass insulators. Thanks for the tour!

A video about a mobile substation would be pretty neat
I posted one about 1-2 years ago! 😀
@Bobsdecline awesome, I'll check it out! I've been binge watching these videos and they're great. Keep it up!
Appreciate that very much David!
Nice job Bob. I was a hot stick lineman on the 345kv lines in upstate NY for 30 years and loved the work. I always felt that the distribution line work was much more dangerous that what we did even though we were up 85 to 130 feet and at the higher voltages.
👊 Awesome vid. I'm on the other end of the phone talking to you guys. Always love seeing and hearing stories from the field.
I’m a retired Steel mill Electrician I have trained with linemen in the same craft your in. I seldom dealt with anything over 12,277v but it always was interesting.I worked in PA USA.
Old style sub, brings back memories Bob, Thanks, Relay Tek
There are several VERY important reasons you don't open those switches on high voltage lines under a load. This is Bobsdeclines channel so I will leave it up to him to decide if he wants to get into detail about why. I will just say on one of the substations I designed in Europe an idiot opened up one of the lines feeding that substation from about 2 KMs from the substation. He put about 25 thousand customers out of power for several hours. Several hospitals and other critical places had to go on generators. I am sure Bobsdecline can relate some stories.
I've never seen a double-circuit line quite like that one! Down here in the plains, they'd be separate structures on the same easement.
Cool video! I'm a Jounrymen Electrician in Minnesota and you explained what a few items were that I didn't know. Thank you!👊
This is my first video from you. Retired from maintance. I have worked with 480 and have seen what damage that can do. People have made mistakes with that and survived. With the voltage you work with not so. A few years ago there was a linesman rodeo in Shakopee, MN. They talked about a linesman in a bucket 6 feet away from a distribution line when it arced to the bucket, Even doing the right thing can be fatal. Be careful please.
Quite cool that the REIN (Repetitive Electrical Impulse Noise) coming off those lines is enough to interfere with the CMOS sensor in the camera - that's what the occasional spots appearing throughout the video are.
Thanks. Watching from Greenville SC. Thanks for sharing "your world" it was very interesting. Blessings, John 20:29
Thanks for the Tour. Watching from Vernon, BC. 👊
Watching live from West Virginia, USA.
That substation x-fmr kinda looked like it has a leak on it. Thanks for the video keep them coming, great job 👍
thank you for your time and expertise.
I'm watching from New Zealand
30 amp fuses for a cool 2 million watt per phase transmission line. Bet they're not cheap! The thought of opening one of those switches under load is sobering. I see why they only do so remotely. Neat stuff, thanks for the look.
Watching from Montana USA 🇺🇸
great video, watching from Brazil 👊 !
Tech tip, if you put your phone camera on manual exposure when you’re doing a shot like that in the truck it won’t brighten and darken when you move your head like it does when the cameras on automatic. Fascinating video by the way we’ve all seen these things it’s interesting to see how they work and what’s in there
Oh nice! That's a huge tip, appreciate it 🤝🙌. I've actually scrapped some footage in the past because of this.
Also thanks watching and taking the time to comment 🙏😀
Nice!
Fist bump from West Sacramento California Another top of the mark video sir!
Always found walking around inside live substations somewhat disconcerting with all that electricity buzzing over my head. Fortunately most of my business usually was away from the bulk of the sub..it was an eye opening job for sure.
Learning all of this stuff is cool, even though I will never personally need it. It is kinda fun when I point something out like those voltage regulators completely off the wall and the reactions I get, thanks to your education. :) I don't always watch useless stuff on TH-cam... I love the engineering aspect of a lot of things.
There's a medium sized switching station near me; there's a big, rectangular box (maybe 2x the length of a shipping container) at the front of the station that was replaced within the last... 10 years? It caught fire and blew up. I was without power for a few days as they trucked in a brand new one and wired it in.
For me, any voltage is intimidating. I won't work with electrical while it's on, but off, single phase work isn't bad. I wired my garage with 240v, 50A service in a subpanel and replaced my main load center myself, and the service cable from the meter to the main panel. Had to replace the service cable as the sheathing split in the back of the cable and let rainwater straight into my old breaker panel. That was fun trying to identify (thought it was a leak behind my basement wall at first).
I forget where Aaron works, but the TH-cam channel Practical Engineering recently did a video of the 2003 blackout that involved Michigan, Ohio, PA, and a big chunk of Windsor, Canada. Incredibly interesting to know that power on the giant steel towers, can flow in more than one direction. I always thought it was just one way. Who knew? :)
Yea that was definitely interesting hearing power can flow in two directions at once from that video on 2003 blackout practical engineering. Lost power during that event and am served by a subsidiary of First Energy.
@@austinspringer5153 I'm in SE Michigan. I was at work (Radio Shack) back then when everything went dead. I was nearly out of gas in my truck too; I had planned on gassing up on the way home. Didn't happen. We got really busy after the power went out with customers coming in and buying batteries. I can't remember how long we were down for, but I remember tons of people thinking it was a terrorist thing. Glad it wasn't.
love ur videos .keep it up.
ive been a sparky for 15+ years and alot of people think its just so simple but it really isnt.
its dangerous, dirty , and dangerous..
keep up the hood work!!
Watching from slc utah, I enjoy learning about this high voltage stuff
I too am watching this from Utah, (Lehi) but work in SLC as an estimator for this type of work & just found this channel!
Watching from Estacada Oregon👊
From Traralgon, Victoria, Australia, different voltages but looks similar to what we have in Australia. Nice work.👊
That's a bulky 69 kV fuse. We don't have such in my country. Thanks for showing it 👍
First time watching, subcribed after 15 seconds of watching!!
Great videos, great info!! THANK YOU!
Watching from Houston TX.
There was a guy named Al Ineman who worked for our electric utility.
Hah no way! Nice
Nice kvs!
Fun fact, in WW2 the british sent balloons aloft that dragged long lengths of cable that would be carried east towards germany for the purposes of losing altitude at the correct distance and dragging the cable over power lines and substations. One balloon succeeded in knocking out and heavily damaging a power station inside germany. The US damaged substations in Bosnia using a special munition that disperses strips of aluminum foil, they crippled the power grid. You can just imagine the headaches caused for sub stations if its in an area that has thousands of on roof solar installations all putting power back into the grid with varying voltage and sine wave quality. Some inverters will even 'drop off' randomly when they cant match spec with the grid. So in summer, on a clear sunny day, the voltage can surge in an area and the backfeed production will push up the voltage causing the home/business located inverters to drop off, and this happened in Victoria, Australia in a heatwave to the point that it caused blackouts and brownouts. Victoria did have base load coal fired stations meeting most of the demand, but the sudden drop out of solar production unbalanced the grid enough to trip the systems. In winter, when there are bouts of very overcast weather and no wind, renewables decline to almost nothing and Victoria has to borrow power from inter state and run a lot of very expensive natural gas peaking plants to meet demand.
Yes,I'm watching it from a rural area just north of Sydney (Newcastle area) in Australia.
It seems that our local company (Ausgrid) who bought the poles & wires off the New South Wales government & has leased it back to them has done away with a lot of the 66 kV high voltage feeders within the power distribution grid except perhaps for the coal mines which are still powered by a 66 kV high voltage feeder network which is stepped down to 11 kV at the mines sites substations & high voltage switchrooms.
Back in 1930,the State Rail Authority were actually the people who erected a 66 kV high voltage feeder in our area which was connected to a substation which was also supplied power from a local coal mines (Richmond Vale Colliery) own power station as it supplied electricity to run the conveyor system & the water 💦 pumps for its coal washery.
It supplied power through a corridor to a substation further north which supplied power to our area even before my parents were born, while it was left erected for 63 years,a separate 132 kV high voltage feeder was ran to it & in parallel at a later date when they started building larger power stations.
Our town has had the 66 kV feeder pulled down in 2013 when they began to a erect a twin 132 kV concrete pylon structure which supplies the substation at the end of where the 66 kV high voltage feeder ended & further onto a brand new substation 200 kilometres north of the point of origin which is our local aluminium smelters switchyard which is supplied with power by a twin 330 kV tower structure from our local power station (Eraring).
Ausgrid built us a new 132kV-11kV twin 37 MVA transformer substation in 2013 which was officially completed & commissioned in 2014,it is located about 20 kilometres North of the aluminium smelters switchyard.
A lot of the old 66kV feeder was dismantled or converted into a 33 kV feeder which tees into an existing 33 kV feeder as a backup supply if it has to be deenergized at its point of origin for any reason.
Many other 66 kV feeders have been converted into 33 kV feeders which are mainly used in an Urban area, they even do away with 66 kV feeders in a rural area now & have 132-33kV or 132-11kV substations instead !
VERRY INFORMATIVE!! I LIKED IT!!! The fence arround the substation seem very secure. I mean, another layer of metal mesh on the fence and very big rolls of barbed wire on top. We definetly don't have this level of security in here in Quebec. I think all of our station is just standard galvanized fence (grounded of course) with 3 wire of barbed wire on top if we are lucky.
Electricity is so complicated yet so simple! Start the voltage high from the power plant, and drop it down as needed to deliver to sub stations, transformers, businesses and homes. Let's ya use relatively small cables to deliver major amps at high voltage.
An excellent video. 💙 T.E.N.
When I was an apprentice, I was putting cell towers through transmission towers. 266kv, 220 feet in the air. We started the day by climbing the tower, and we stayed up all day. That job was a ton of fun.
What if you have to take a shit
@@TerminallyCh1ll then, naturally, you'd come off the tower
Wow interesting, watching this guy makes me wanna take electrical over conputer science lol...
You ought to see the linesman *hanging* from a *helicopter,* maintaining *live wires. Scary.*
@@BritishBeachcomber think of it this way: if you slip, it’ll be the last slip you ever make. If you do this, you make DAMN SURE of every step you make.
5:26 one important thing you left out is that arrestors are semiconductors :3
They will conduct only if the voltage is raised beyond normal operating limits, clamping it hard to ground and will stop conducting when the overvoltage is gone. But yes they do actually have a leakage current and it also grows with every time it fires
There's one on the transformer on the pole across the street from my house that is conducting in such a fashion that it is generating RFI of harmonics of the local am radio station. 1350 AM heard as a 60 hz modulated on 2700, 4050 and 5400 kHz in 60 meter ham band. I called power company a year ago, nothing done. It only bothers me, it doesn't travel far.
@@mikekokomomike I don't think that's the case. In normal operation they are just a simple resistor, there's nothing smart in them. They either conduct or don't. It's just a very big diode
@@whatevernamegoeshere3644 didn't you say that they conducted more after each surge they take? I know if I walk over to the pole with a receiver the ground wire is hot with RF. I have a spectrum analyzer and it is very visible. Maybe it's a corroded joint.
Thank you for the video. BTW the previous one was fine. My first thoughts "hands in pockets", lol but I remembered what you said (dispatch, perimeter check...). I noticed that there is a lot of equipment mounted on wood. I guess that needs to be rebuilt every once in a long while.
HEYY Aaron!! 👋👊🏼💪🏼🤘🏼 Much love brother! Love your videos! It’s just so interesting to me 😃
good videos Bob, could u make some detailed videos about how these substation assets are connected to busbars and ground. talk more about connector types such as side formed, 90 degrees, and connector compression types. thx
nice
Nice substation.
Excellent
Howdy Bob, nice channel and I do like the content. In watching what you present I have learned a lot about the "delivery side" of what the customers use. I was in traffic control manufacture for about 30 years and always was curious about the utility side of things. At our home we have breakers on the pole that covers an area for our neighborhood and down the street a ways. Really makes ya jump when one of those things go "Pop"! I am trying to figure out a way to convince our power company to move my power line to our home to a different transformer so I don't suffer the consequences of people not cutting their trees back. Thanks for your time and willingness to share your knowledge so we may be enlightened... no pun intended. By the way, I live in Oregon and I go by Bob also. Take care, be safe!
Increible los postes de madera. Aquí en España para baja tensión los postes son la mayoría de hormigón, y a partir de media tensión, todos en hormigón y/o celosía metálica.
Hey man been checking out your videos iam a electrician in the mining industry but work with the same equipment we usually use the same line voltage from the utilities just run through a separation transformer our safty devices and arresters before heading underground with it nothing like being in a confined wet space with 12470 lol keep up the great vids
I used to live near a 400,000 volt national grid switching station. Whenever a breaker tripped the inert gas spark suppressor sounded like a massive explosion.
Fun video. Thanks 4 showing us around
Wow awesome video, thanks for taking us inside ... I kept thinking "Danger Zone" as you were walking around :D
Thanks Tom! Good thinking, the entire inside the compound is a danger zone!
Thanks again for another great video. Stay safe out there- respect from IBEW LU#41
Thanks Dean! 🤝
Nice
Loved this. Wish we could see controls too but get why not.
Thanks! A few of the being a lineman videos show a few quick shots of some controls that don't allow enough info that can be used for malicious purpose. Ultimately the instructions can be found online, but there's just too many liability issues.
Hey Aaron I'm Jon watching from Waukesha Wisconsin‼️‼️‼️‼️
Hey Jon! Thanks for stopping by 👊. What's the badge in the profile pic? FD?
@@Bobsdecline it's from a former railroad that got bought out from the Canadian national where I live we had a railroad called the Wisconsin Central it got bought out by a Canadian national in 2001 so the badge was a former Railroad police badge I collected on ebay.
Oh nice! Very interesting, thanks for the reply!
Was this particular substation built in the 70's? Im not a lineman, but ive been fascinated with powerlines since i was a kid. I appreciate these videos they are awesome. Watching from Palatka, Florida. 🤜
Nice video! Thanks!

We have a 500 kV AC line beside of our city. It really strikes your butt when riding bicycle underneath those line. I mean literally HV electric discharges are jumping between metal parts and human body.
🤜 from Berlin, Germany
Man, when you say this is a basic substation, you ain't kidding lol
Like your videos my company won't allow anyone to video record anything they said it's a distraction to the work being done. Likely also they want to control any video footages being created on their property. IMO videos like this give the public an inside view of what it takes to flip a switch turn a light on at home. During thunderstorm season ill see lot of people complaints about loss of power for a few hours or even my neighbor complain that he had to reset 3 clocks. Shows how bad of a job they do in communicating with the public how electric power is created, and brought to their homes. I'm not on the T&D side of the company but I do go to substations, and powerplants for other work.
Me: "That must be the flux capacitor"
Him: "It's the high voltage metering tank"
...
Me: "Of course"
🤣👊
I would like to see how one of those disconnects work. Maybe you could put an unpowered spare one on a bench and shows us which bits move?
You ought to do a video of how a residential transformer works, and what said transformer is made of!
Ah so that's why you Canadians do that snow thing up there all the time -- footprint detection medium! Genius! ;-)
whats that?
Very good video Aaron. Thank you.
I was noticing the razor tape and double layer fence. I take it you have a lot of intrusion for copper theft? I live near a 500Kv switchyard and it's perimeter is patrolled by security guards because the fence was cut open on a almost weekly bases.
There is a weird thing I havn't seen in any of your videos on the power that leads down my valley here in Alaska. Single phase to serve my valley, that just a mile down the 12 mile valley, like 5 houses before it on the line, and 250 houses after it in the rest of the valley. Looks like a transformer. One wire coming in, one wire coming out. Like those voltage regulators. But this is easily 3-4 times the size of the ones in that substation. Only thing I could think of was it was some sort of voltage booster. Can't really get a good loot at it though, they have it up on a platform on a pair of twin poles, and huge sheets of plate steel shielding it. Pretty sure that's to protect from gunfire. Damn near everything gets shot at here.
Thanks for the video and the explanations!
