Just out of curiosity, what is your background and how did you get into this? I'm an electrician and high voltage SAP in the UK and would love to see this side of the industry
Guys did a good job. I have worked with different companies providing UD training. Some companies don’t provide enough training and the proper tools to properly make these terminations. My experience has taught me that some of the less experienced think that if it holds upon energizing everything is ok. They do not know or realize that improper termination of medium voltage cables with the proper tools will eventually fail prematurely. I came up with I company that provided the training that taught us why we take all the proper steps in UD terminations and the proper tools. While providing training most of those that didn’t follow each step required by manufacturers just didn’t know. Most these guys want to do it right
How many errors did you find here? No proper tools and some cuts are way too deep. The edges are not as clean as they should be and some effects at the edges might appear. Kudos for working with these tools and maintaining the grid with this.

Much prefer load break connectors. Fast off and on loaded or not, simple grounding of the cables and the primary for safe service work. Far superior. But good job on this one none the less.
If you want right, you better watch other channels, like jointech cabling. As for the issues: They didn't apply the proper torque spec in the end and they scored the conductor, as you can clearly see around the 9 minute mark.
The craftsmanship is very skilled. For future inspection and maintenance, I feel that if the three-color tape is wrapped on the wiring cable to separate the phases, and whether the phase sequence is marked on the cabinet body will be clearer to the staff.
No. Phase sequence is not determined by the body of the transformer. Phase sequence is determined by the actual phase of the voltage on the cables. You can actually change the order of the cables connected to the transformer and as long as the output cables are also correspondingly changed, everything is good. So the correct way to indicate the phase of the electricity is to mark the cables first and foremost. You cannot not do that. It must be done.

Scoring the aluminum when removing the white nylon layer is a no, no. Yes I have done industrial underground power vaults and you don't score the conductor with a blade while removing insulation.
@@DrHarryT I know I'm an electrician , as long as the cuts are not deep and non of the strands are cut off thus reducing the csa of the conductor which is not gonna happen on cable this size, then it will be fine but I won't disagree with you that its a no no I'm just saying cable this size with a slight mark from a Stanley blade.. not really an issue is it let's use some common sense here
@@LordLorenzo834 It was well over 30 years ago and I was not actually making the connections but an observer apprentice, Working with MCM1000 AL they had specialized strippers that cut 95% through the plastic rolling it in a circle with end cutter set to the same to cut down the length of the cable so the plastic would easily peel off leaving the AL completely unscathed. The thing about AL is once you score a strand it creates a fracture point when you crank it down in the lug and the strands distort, it can cause strands to fracture/break completely through. AL it brittle like that. Of course you must also use Noalox as I recall.
Seriously! I built a few load breaks as well. Yes i saw a couple things i would do different but the teamwork housekeeping and attention to detail was pretty damn good. What stood out to me was when my man filed any burrs off lug after crimping. R That spoke volumes. I was trained by 3m and ive had to build these things in nasty paper mills and pwr plants. These guys are better than most of the shit sticks I left behind in contracting. I say if it passed high pot test and im sure it did then good job.
Crimping the terminal directly on the insulator is an unnecessary risk in my opinion ... it could break !!! for the rest, great manual skills, word of an electrical technician
@@blackviper7754 Yes I am an electrical technician and I have worked with terminals up to 30KV I have never crimped directly on the insulator above all in glass or porcelain where breakage is at high risk
Professional but random work brother. You work in a field where you must have advanced tools in order to work, especially we are talking about the field of electricity. Good luck
Больше всего мне понравилась идея надеть на контакт "Y1 конденсатор", выполненный в виде внешнего черного корпуса. Вот так и нужно заводить электричество на дачу и в квартиру, т.е. с использованием конденсатора в месте контакта ввода. Не силен в физике, но по-моему по проводкам заземления из кабеля будет уходить на землю вакуум через конденсатор. Было бы любопытно измерить емкость между кабелем и заземлением, наверное ~2nF.
Absolutely nothing is right about this installation. 1: wrong type cable for the job, single cores in a trefoil should have been used instead of a multi core cable 2: wrong type termination kit used, a break out or multi to single core kit should have been used which keeps the screen on all the way to the dead break elbow. 3: no grommet or gland used to seal the in enclosure from ingress or moisture 4: the clamp is installed at the crutch which will cause stress and early kit failure Solution: have your technicians trained and educated properly. Government should introduce a standard based apprenticeship system. Follow jointing kit instructions to the letter.
use extended elbows EZ FIX ...we have even cut off OLD elbows short and still re use the old cable just have new elbows and lightning arresters ..this is just a 3 phase going IN im sure they got 3 more on the other side.
Nowadays, there is no need for stamping pliers on the terminals. It is safe and fast. Also, the protective cover is not very good if it is heated by fire. Now there are terminals that do not need to be burned. Just put it on and it can be used.
You sure? Did you see them apply proper torque on the bolts using the proper tool? Did you not see the scoring of the outer conductor @9:00? I sure as heck did not. So if you please, would you guide me to those missing pieces?
@@Milten130 true story: I went to an outdoor lan party back in 2000. Big army tent, diesel gens, etc. The power was ..... bad. Loads of parasitic voltage through the earth lead. So we all tied our computers to a piece of UTP cable and wrapped it around a couple of tent pegs. Then through the magic of powerstrips, all our computers were all cross-connected to many small grounds. It was enough from getting us zapped by our own computers tho, as stupid as it looked.
4:05 it’s better to start tape wrapping at the bottom and move up towards the top. This way each wrap covers the top edge of the last the way that shingles do and help prevent water getting under the tape.

If you are going to only use music for sound, and if you are going to loop it, please choose a song that is longer than 15s.
Yes, it's fucking annoying
Personally I prefer a good 10s loop to a shitty 5 minutes song
I wanna make that song my ringtone. I had no problem with it. I was actually more interested in what they were doing than listening to the song.
Sounds like adult film music from the 80s.
Yeah, that's hideous.

crimiping start always from bottom of lugs ....like this chance of cable to sleep downwards
You are wrong. It will leave a gap when connector grows

@paolo D'Olimpio - I thought the same thing. I’ve seen plenty of cracked bushings cause ground faults, spectacularly.
All the beauty got ruined at final thanks to those damn groundings. Great job anyway 😉
Good job
Que mala onda de TODOS LOS COMENTARIOS, de repente todos son INGENIEROS, yo creo que son puras mulas, BONITO TRABAJO. ✔✔
How come they applied (dieletric?) silicone grease to the contact area? Shouldn't grease be applied after making the contact crimping?
I assume they do that to slip the bigger piece over?
My best educated guess is that it's to mitigate oxidation inside of the crimped lug.

Good work!
Big cable, compared to the physical size of the transformer. 500 kcmil @ 13.8 kV, corresponds to 10 mVA?? Transformer seems smaller.
Absolutely nothing is right about this installation.
1: wrong type cable for the job, single cores in a trefoil should have been used instead of a multi core cable
2: wrong type termination kit used, a break out or multi to single core kit should have been used which keeps the screen on all the way to the dead break elbow.
3: no grommet or gland used to seal the in enclosure from ingress or moisture
4: the clamp is installed at the crutch which will cause stress and early kit failure
Solution: have your technicians trained and educated properly. Government should introduce a standard based apprenticeship system.
Follow jointing kit instructions to the letter.
i have question
do we use phase sequence on Higher side of transformer like in this case he didnt use any sort of color for different phases.
worst fear: accidentally cut the cable shorter so it doesn't reach the contacts
Get so m.h e thick ass solder and a torch lol.
There's even parts for that, if someone mess up, or changes needed. Otherwise it needs I-joint and some cable, angry boss and try again! $$$
Other worst fear: getting the phase rotation wrong when its done.
th-cam.com/video/f0k2aUizj4s/w-d-xo.html
use extended elbows EZ FIX ...we have even cut off OLD elbows short and still re use the old cable just have new elbows and lightning arresters ..this is just a 3 phase going IN im sure they got 3 more on the other side.
I'm not really qualified to question anything but wouldn't a heat gun be safer than risking frying insulation from the cables?😮😮
Михалыч! мы внешнюю термоусадку забыли надеть. снимай обратно! xD

Different from what we learn during our training in raychem
very good💪
This is confusing and seemingly good
Y’all did good until you took off the vinyl insulation and went too deep, putting a deep nick in all the outer conductor strands.
great job lads.
All protection is good but earth connection is best important part

Why was this black insulation peeled off like that at 6:45? wouldn't it have been easier to file it completely from bottom and then just pull it off?
