I just got back from a subsea cable termination for chevron in angola, power and fiber, the experience was awesome
Guys, NO! You do NOT use a naked flame on the shrink sleeves!!!! Heat yes; naked flames no!
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
👍
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.
Thanks from France, really good work !
9:00 seems like the most dangerous part, both for the cable conductors and the bloke's thumb.
ماشاءاللہ میں بھی ریاض میں شرکہ کھربا میں اس کام کی ہیلپری کرتا رھا بہت اچھا کام ھے
Чудова робота! Молодці!
Mr Asf I appreciate ur work dedication / tc urself during working
Saludos DESDE BOLIVIA... soy Tecnico Electricista.. muy buen video 👌
Professional job well done
꼼꼼하게 설명 잘해주시네요
Very professional and neatly done job.
Excellent professional installation..
Good Job!!
not really - no safety glasses at all anywhere.
The cable clamping bracket was pretty average!
Parabéns, é satisfatório ver um trabalho desses ser concluído sem falhas. Pernambuco - Brasil.
Excelente presentación muy buena gracias
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.
This is a ticking time bomb. Get a qualified Jointor . Jus pay attention to how he removed the seni con layer,This is a NO NO.
@@rajthanya с помощью ножниц для резки пластиковых труб... SUPER-EGO не делает инструмент для снятия изоляции с кабелей. Наружные проволоки надрезаны по кругу...
Manchmal nervig, aber manchmal auch schön das es hier Standards gibt.... Oh mein Gott ....
its nice to see someone doing things the right way in one of these videos.
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.
You FLICK the switch...
The LIGHTS go on!
Good work, gentlemen!
"Глаза боятся руки делают" " Опыть приходит годами" "Семь раз отмер, один раз отреж " Музыка несовсем,кто монтировал ролик имей ввиду ! Работа окуратная, хорошая.👍
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.
Good work!
Big cable, compared to the physical size of the transformer. 500 kcmil @ 13.8 kV, corresponds to 10 mVA?? Transformer seems smaller.
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.
Mr pedantic I don't know how you even seen that , a bit of scoring on the cable isn't the end of the world man
@@LordLorenzo834 Ot's a no no per electrical codes.
@@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.
How to derate the line by scoring the outer row of conductors. @ 9:00
Looked like it was done by the bloke with the conduit cutters. Not good
Doesn’t that cause resistance/heat and worse? I am taking my first electronics class.
Great work.
Respectable professionalism.
Reall enjoyable watch.
Thank you for sharing.
Did you use a dull axe to cut those holes in the clamp bracket ?
No, they seem to have burnt the holes with a welder
Good job 👍
We shall take little more care when sleeving insulations and clamping.
Thanks for the video.
God job brother and bravo every one amin❤
Excellent job
👍👍👏👏بسیارعالی
Good job. So many unhappy people here seeing work being done well
Thank you😍
Good job guys with adequate toils il would be better
Nice work ❤
السلام علیکم ماشاءاللّٰه ماشاءاللّٰه
Nice work 👏
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.
Trabalho bonito e profissional. Parabéns a toda a equipe!
Good work.
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?
The right jobs are done with the right tools.
Just like in the 1970s when I studied electrical engineering in Rome
PS ; is the Bucholtz relay still used?
Great job
Good job!!!
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.
Excelente trabajo 👏🏻 👍🏼 💪 pero algo muy importante los EPP
Elementos de protección personal ✅️
Knowledgeable able vedio
Nice work but please wear safety glasses especially when using a Sawzall to cut wire!
Very Good....
great job lads.
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.
Nice working.
Good job brothers
интересный вариант полупроводящий слой ножом снимать так бывает на одном кабеле из 100 и не нужно говорить что это только на импортных , так же там инструмент нужен
I specialize in this! Only minor errors but congrats.
well done, it was a clean and professional work
Ram ram Asif ji 🙏🙏
Во дела, даже инструкцию прочитали.
Why you have not filled gap between lug and adaptor. this may create partial discharge
good job!
Excellent work. It might get a fault but it sure AF isn't going to be the primary feed connection 😎
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?
@@patrickd9551 also resistance to ground is not important there, they can just go by with crusty torch cut metal 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.
Very good job
why did you cut the sleeve from the adhesive coating side? and you need to use the tool for making cut on Semicon.
nice video boss
❤❤❤ Super
Medium high voltage of 13.8 kV. They do a good work
Fellas. Think about your eyes . You have flakes of aluminum flying. We always wear eye protection . Especially when cutting wire with saw.
Странно что при таких сечениях кабеля точка контакта совсем маленькая, там где гайка.
Это высоковольтка там и не нужно большое сечение, там токи очень маленькие, а вот 0.4кВ уже нужно больше сечение из-за тока
Сечение выбирают исходя из патерь. На длинной линии прийдется переразмерить сечение что бы снизить потери. Иначе ПБВ не хватит и напряжение будет сильно зависить он нагрузки. А гужоны в изоляторах бывают разными здесь видно что тр-р не сильно мощный.
Да многое странно!
Зачем высокую сторону подключать таким большим сечением провода?, если исходя из расмеров тр-ра, то его мощность не так велика.
Еще обратил внимание, что когда закроется крышка, то клеммы окажутся совсем рядом с нею. А заглушки на клемах, это так себе... всёже 14 кВ.
@@user-zx4nw1pr6q расстояние там позволяет, у нас ячейки открываешь и сразу ВН стоит и кабель, и расстояние 10см, про RM6 молчу там еще меньше места, до крышки ячейки, все же нагрузка там есть, по высокой максимум 70А, ТР на видео примерно 1600А по низкой это в районе 2312А
@@Grishagin1997
И тем не мение, там сечение минимум 300 квадрат, и на ток в 70А?
Ну да ладно. Как говорится, хозяин-барин.
А вам спокойной ночи!👋😉
Before applying silica grease.. Should be rubbed with smooth sand paper on grey layer
No, you shouldn't. One little scar on the dielectric layer and bye bye termination.
why
You kicked the aluminum conductors with the conduit cutters when you removed the inner insulation layers and you should not use retractable blade cutters on HT cable, there are special knives for removing insulation. Did you put dielectric grease on the TX stems before putting the boots on?
Where is the QA at!
They probably don't even have multilins or sweitzers on the high voltage side.
@@schamberlain1 I should have said nicked the conductors, but that is what happens if you use a stanley knife to cut through the outer layers. We use to use venitian blind cord to cut through the outer layers, the friction cut through the plastic layers with out damaging the copper conductors.
This looks like a dry climate
@@XREXP0 It is dry, and so they don't have horizontal venetian blinds, but the vertical ones with a stiff staff to open & close them.
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.
VERY GOOD,,
I'm not really qualified to question anything but wouldn't a heat gun be safer than risking frying insulation from the cables?😮😮
Good job
Three guys to do a one man job an the rest sitting around watching.
imagine the GDP growth
very good💪
Nice 🎉
Hello! If I understand correctly, you work in oil production. Are you connecting a control station and a step-up transformer?
If yes, then compliance with safety regulations is at a low level ...
You work at least - without a protective helmet, goggles and gloves...
Does the opening at bottom get closed off or can any animal build a nest/home up there?
변압기 각 3상에 터미널 물려놓고 압착기 찍는 거는 처음 보네요....
잘못하면 변압기 부싱 망가져요..
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.
ua-cam.com/video/f0k2aUizj4s/v-deo.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.
crimiping start always from bottom of lugs ....like this chance of cable to sleep downwards
why did they lubricate the exposed part of the cable with silicone this will worsen the contact
It's probably has dielectric properties so when tightened IF any is between it shouldn't effect much, on the other hand it should provide waterproofing, oxidation and maybe lessens the chance of arching (not sure how effective on high voltage but on main breaker panel thin layer on rail contacts might prevent arching when breaker is installed in that spot..
Thanks bro
Don't put silica grease on conductor,
I know right? Doh!
Very good
You never wanna use a constructive material to secure MV cables inside equipment.
Proper application would've been some sort of fiberglass bracing.
Was not fond of the stress cones on those MV terminations.
Tying and bonding to a grounded rod or job ground-loop may have been a better idea. I've had to do so even on smaller, pad-mounted XFMRs.
Прикольно смотреть !
lubricating contact joint is priceless 🤦
Plus the box cutter technology.
My favourite was the clamp/strap that secured the cable in.
It looks like they drilled the holes by shorting it out on a car battery.
At 0:51😂
looking at the cable, I think that some-one misplaced a decimal point, as one would not want to use any voltage below 400V/3phase for any substantial length .. this looks like 200V and looking for a 1.5% drop. maybe this is cheaper than a transformer in the short run. the cable looks to be 2.5cm dia. PLUS the definition of " Medium Voltage Cables" is 2.4kV and above.. so is it MW that we are really looking at?
First time ever?
All protection is good but earth connection is best important part
Perfect
How do you know which cable is which? They all seem to be identical.
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
Definitely. 🙏
So are you electrician?
@@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
@paolo D'Olimpio - I thought the same thing. I’ve seen plenty of cracked bushings cause ground faults, spectacularly.
Mashallah 5000kw good 👍👍@electricalpowerpk
ماشالله ❤❤❤
Those nuts need to be torqued to mfg. settings. Didn't see a torque wrench being used.
The real question is: can you still do an MRI with aluminum chips in your eye?
