I'm a retired Lineman / Cable man of 38yrs. This may look more time consuming, but compared to hand taping as I was taught early on in my carrier, it is more faster. Price is very expensive, either way, you miss one step on primary voltage and your screwed. You'll see extra pieces on trucks when you had to open a new kit to replace one part, then you have to answer for the added cost to the project. Trick is when working with high voltage cable slow and easy, faster you go more mistakes happen. I encourage all young'uns to look at this trade, it was very good to me.
This protection tube doesnt protect anything, therefore another protection tube is applied. Now its time to apply another protection tube to protect the previous two protection tubes. And finally a protection tube is applied on to the previous 3 protection tubes which doesnt protect the connection very well.
When you have a cable with 30kV and 3kA in it you really , really, really , really don’t want a leak. There’s enough power going through a cable like that to vaporize a bathtub of water in couple seconds.....
Borkzilla I’m thinking this splice is probably made on a power line up in the air. Not underground. Underground lines are contained in conduit. This line did not appear to be contained in a conduit. In fact it looked more like a communications line than a power transmission line.
Cables in Australia are buried direct, and the jointers Dona bit better of a job of making sure it ain’t going to leak. Sure, this is a demo, but I see a few bits that could encourage water to wick in.
Nice video, and after seeing the comments below, I can tell there are a lot of hacks commenting. There are good reasons for having connections like this, sure there's more than one way to skin a cat, but if you have to have a connection that will out last the rest of the cable and be safe while doing so then this it. Plus it keeps the guys with the clip boards off your back.
About a 100 years In the future , when they find this thing and carefully forensically unwrap it expecting to find ancient power crystals. They are gonna laugh for hours when they realize its a wire splice...
I have to say, I'm impressed, I did not know so much work went into making these cable joins. I'm glad it does though, that's not the kind of cable you want coming apart.
Man, I wish they explained what everything did and why it's useful to use multiple layers etc. But probably the target audience already knows the details.
NEEDS MORE LUBE! (OR TAPE) LOL AND.... IT'S 2019, HOW DARE YOU REFER TO GENDER THAT WAY>??!!? IT'S "IF I COULD ONLY FIND A XXXXXXX" INSERT GOVERNMENT SOCIAL JUSTICE WARRIOR TYPE PRONOUN AFTER "FIND A".
think theres same amount of tape if not more .. he be better with silicone wtf he doin to it 😂 😂😂 3m I used to work in a place that cut their tape rolls 😂😂😂 fuckin Neva sent us this shit lol
1st MV termination I was involved in as an apprentice went to shit and blew up a 4160v switch at a NORAD site on Antigua in 1987. It was just after dark when the base lineman called the power house and told them to energize the circuit. I was great fireworks display! I am just glad I was the apprentice and essentially handed the Journeyman tools and other items as he did the work (did the work wrong evidently). I flew back to Florida the next day and missed the ass chewing on base.
😂 Great story. Better him than you at the time, but you know too that you may have the same responsibility at some point. It’s learning by mistakes be it yours or others. I like redundancy and having either a coworker, senior, or junior checklisting every step to insure a proper job with complex and high risk tasks. I’m no electrician by any means, but the redundancy works with other trades tasks as well.
Doing the same job here in America, using 3M products, I feel that ours would hold up longer. The process is different, but same idea. We use a one piece outer boot. Just a different kit I suppose.
TUT: how zu use all our products in 9minutes. And we don't know what tape works the best for this kind of operation, therefore use all in random order.
i don't think you know what kind of cable this is... its for 7Kv-33Kv(after what i can see in the video), if there is any small airpocket between the grounding layer and the inner core then you will see the joint burn over in a couble of hours, or a couble of days if you're lucky.
Borkzilla this line would not be running to a single house. If anything it would be coming from a telephone relay station. High power lines are rarely dual conductor cables. This looks more like a communications cable.
Jat Tan. Cleans cable to remove any contamination. Then applies electrically inert, void filling grease. Best to know what’s being done, before commenting on it .
I love mastic, but geez never seen so much crap used to seal a joint. Might as well of used some glue at the edges of those cool shrink wrap tubes, just to make sure.. but I think its sealed.
That was only one phase.. in a clean room. Now try doing this in a small manhole or in a half water filled ditch.. 3m splice kit does make this job easier.
They had to repair the cable in my yard and it had 10 layers of repairs the whole thing took 2 weeks and maybe 20 guys. And left the directions pages laying in the grass it was kind of interesting
I see a lot of steps that will get skipped unless you have documented quality control checkpoints for each process. And that takes a lot of time unless the inspector stays there thru the entire process.
Sigh at all the keyboard warriors in this comments section. Unless you are a professional grid electrician, please shut the hell up. There are hundreds of engineers designing this stuff to bring society a reliable grid, and some DIY kids here who have tightened a wire nut or two come tell them that it’s not good.
Haha, "How to spend $300 plus half an hour on a single joint". Oh, and don't forget to join a "Training" before you use our tape... Incredible, just incredible!
Shylesh Srinivasan it was pretty clear. This was a cold repair. There are many situations where heat is not permitted. For example, in a joint trench with a natural gas pipeline. In a refinery. In a chemical plant. These are just a few examples where heat would not be allowed.
I didn't think you were supposed to splice primary underground cable, oh yeah I forgot the company can do anything they want when it benefits them ,what was I thinking.
I'm LMAO!!! Just when you think they won't add any more mastic tape/shrink, they just bring more that are bigger and bigger. I seriously thought it was a troll video by 6:55
Obviously this was back in 2011. I don't see the reason to use three shrink tubes when the insulation can be brought up with rubber tape 1.5 % greater than the original OD of the cable.
Because that cable carries like 20,000 volts at 200 amps. Plenty to vaporize the guy's whole arm with or without the ring, if he tried to splice it live.

Too bad I'm afraid of heights :(
Slow is smooth, smooth is fast.
I think 3M wants you to buy some of their tape...
Don't forget their specialty tape knife.
Well, I have to say 3M products are damm good quality. I would pick them over Chinese crap any day.
Yes no but 3M is best
Needs more tape
This protection tube doesnt protect anything, therefore another protection tube is applied. Now its time to apply another protection tube to protect the previous two protection tubes. And finally a protection tube is applied on to the previous 3 protection tubes which doesnt protect the connection very well.
The first is applied to protect the first wire, the shrink tube is the one who protects and the tape is used to seal the shrink tube
Then the tube protects the tube and tape then big tape the ends 😂😂😂
Don’t forget about lube

Embrace the pointless, but oh so fascinating knowledge lol
because you is a dyatelochek :)
My Dad worked for 3M for decades and grew up with a garage full of cable jointing equipment, happy memories.!
Doesn't matter how broken your shit life is, 3M can tape it back together for you
what if you're like me and forget to put all those shrink tubes on one end before you start?
Than your fucked. I know that feeling man. When you solder like 30 wires and figure out you forgot the heat shrink...
Hot glue for life.
duct tape
Super 88 is your friend.
then you’re like me and get to do it again.
Should have made this video under the usual URD cable splicing conditions. At the bottom of a trench during a rainstorm.

@@originalusernamefail maybe they need more protection tubes lol.
@@thewidower1 not all lines under ground are in conduit, that is a power cable with a concentric neutral. They are used for high voltage under ground.

Welcome to the Department of Redundancy Dept.

I think NASA Approves this splice.
even NASA does not have this competency to approve 3M's MV joint.
Approved but barely
Needs more tape
Needs more bureaucracy
NEEDS MORE TAPE!! lol
I have to say, I'm impressed, I did not know so much work went into making these cable joins. I'm glad it does though, that's not the kind of cable you want coming apart.
It's good to know Michael Caine is still keeping busy with voiceover work.

Take a shot every time a new 3M product is used for the same joint. Have your affairs in order before hand.
Remember to apply tape to the bottle beforehand.
I have no clue how I got onto this video
Man, I wish they explained what everything did and why it's useful to use multiple layers etc. But probably the target audience already knows the details.
Essentially, everything thing inside the mesh is electrical isolation and everything outside the mesh is mechanical protection and moisture sealing.
This video posted 7 years ago and now i see in my home screen of youtube was satisfied

How far will a 3M 2228 Mastic sleeve go up a 3M representatives ARSE.
May I ask, what would be the purpose of this application?
You may want to find a cheaper solution for your problem!
Imagine completing a splice and realizing you forgot the heat shrink.

gosh so mee
I need to contact your repesentative in Egypt. I have a big project and need big quantities @ 3M UK & Ireland
These sort of videos relax me..
Brings back nightmares of doing hundreds of these.
Man that was something. 3M is the best!
This is fascinating and I'm not even an electrician.
That's a million dollar splice (3M to be exact)
This is one time super job, for maximum security coverage!!☝️

I don't own a trans-atlantic fiber-optic cable but is there somewhere I can buy this? I can find a few uses for these products
Top notch bass playing in this song.
Interesting, but the cable preparation phase is missing.
That job looks majorly EXPENSIVE. You know 3M doesn't sell all that stuff cheap !!
i don't think you know what kind of cable this is...

kV*
Small k for kilo, big V for Volt.
In large companies nothing gets done in the 100$ range.. Amounts of 5000 - 10.000 $ is a normal bill.
Wouldn't you want it done right if it's the splice powering your house?
Borkzilla this line would not be running to a single house. If anything it would be coming from a telephone relay station. High power lines are rarely dual conductor cables. This looks more like a communications cable.
I dont get the silicone grease, i know it has good dielectric value but why a grease?
I already thought it would be something like bending moving
Thanks! :D
1:40 wipe cable to remove grease
3:17 applies grease to cable

Ok sir
I have no idea what I just witnessed but it was cool as hell.
how much this work??? and tapes glues.... i only use a glue bonder and finish
Wonder what that splice cost? Including labour!
I love mastic, but geez never seen so much crap used to seal a joint. Might as well of used some glue at the edges of those cool shrink wrap tubes, just to make sure.. but I think its sealed.
anyone who knows what's the "name" of the tool he uses to keep the connector stable while he "breaks" the bolts
What is the song in the video?
Why did I watch this? I couldn’t stop myself. I learned that with enough tape you can fix anything
I'm still twying to figyou out what gwease is.
This is great! I'm sure our company can use this product.
are these heat-less shrink membranes available for 14ga wire?
never ending insulation....
Next: Splice of a submarine power cable.
Get the tape ready...
Proper insulation is needed when you're splicing a cable that'll carry up to a million volts.
Is the guy's wedding band 3M branded?
I think this video contains the most entertaining comment section of all time
That was only one phase.. in a clean room. Now try doing this in a small manhole or in a half water filled ditch.. 3m splice kit does make this job easier.
I need more videos like this.
i have the feeling they had some extra rolls of these tapes and sought some way to use it^^
Thats such a genius way to do things omg!!!

Looks a bit tough to work with. Great however if in an area were using heat is not an option

still can't wrap my head around how the cold shrink sleeve actually shrinks by itself, it's like if you stretch out a sock, the elastic is gone
Next, 3m will be selling mastic tape trucks in the UK to follow the boom trucks around so the electrician has all 300 types of mastic take he needs.
I'm LMAO!!! Just when you think they won't add any more mastic tape/shrink, they just bring more that are bigger and bigger. I seriously thought it was a troll video by 6:55
You would think 3M would of made one special tape for all of that then then use the shrink tube.
Obviously this was back in 2011. I don't see the reason to use three shrink tubes when the insulation can be brought up with rubber tape 1.5 % greater than the original OD of the cable.
This video would cost me at least 40 dollars just to watch.

I think the tape is a great idea over heat shrink when you’ve forgotten to thread the heat sharing before mechanically connecting the cables 😂😂😂

I can't believe I am watching this...again
Therapeutic watching love it
from 3:30 music should change to "Yello - Oh Yeah"
