Glad to see he's wearing the high voltage insulating safety flipflops.
Stay safe out there guys.
Standard issue. OSHA approved
Why don't you donate some work boots?
@@AnOriginalUA-camr Why doesn't their workplace supply them?
two fuses are made of coat hangers
These guys are not soft and risk-averse, they take responsibility for their own safety rather than rely on mummy OSHA to keep them wrapped in cotton wool. It's a basic culture difference.
13:33 Когда чувак сращивал эмаль провод, показалось, что он алюминиевый. Это фиаско, братан!

Stay tuned for next week's installment where 7 men in steel tipped flip flops pull out spent fuel rods from a reactor and refurbish them for use as a personal x-ray machine.
🤣🤣🤣 was thinking the same thing!
LOL 🤣🤣🤣🤣
😂😂😂
with just ordinary flip flops🤣
"We need you to go up onto the roof and look down at the reactor"
"Well...OK. But I need to go get my safety squints!"
Все на проволоку скрепляем !Совсем прям как у нас.Не удивительно что не продемонстрировали в работе под нагрузкой.

24:06 Waterproof testing for transformers: leave them outside in the monsoon! :-)
Not live wire … firstly he cut voltage from grid than he go near to 11kv wires
@@skillfounder except he was grounded when he was touching the metal pole and standing on metal with non-insulated shoes
I salute the person who removed the transformer from the pole. Very skillfully done. Then transported to an equally primitive workshop where conditions are not only bad but nonexisting. How can one work in such conditions is a subject of research. Let alone repairing a transformer. You guys are INCREDIBLE. And at last hats off to the person who shot the video. Good job done.
Lots of Ignorant comments mostly from westerners , I am an engineer myself and although it was somewhat reckless but they are skilled workers. respect from 🇮🇳.
These dudes are badass. They do fix stuff the primordial way😂
These dudes are idiots, a clear example of what NOT to do to fix something.
Соединение проводов и шин было супер, на одной скрутке 😀
Там олово и паяльник ещё не изобрели) лол.
Там площадь этой скрутки - мое почтение. По госту низя - но работать в масле это будет. А качество сборки - вы видели, он даже бортики у обмоток делал. Явно не первый раз и все ок.
@@crfuture По моему они свои же отремонтированные чинят😀
я думаю что нужно внедрять подошву от тапочек,изолятор хороший,трусов я так понимаю пара пошла,резинкой он трубочки завязывал.Про шину напоминать не буду,в начале видео видно как счетчик просто на столбе висит,под дождем,пофиг,в принципе это и побудило досмотреть виде до конца.
Обмотка Алюминий не Айс . .. мужик без работы не сидит зато !!
Если так работать, без работы никогда не останешься :)
yes this is exactly how utility transformers are made, hand work bits of wood and card, the only difference in the ones made in the UK was the connections were welded not twisted together especially the high current connections
Yeah... Thought the HV side was bad... There's a whole lot of WTF on that secondary side lol... 🤔
welding would be safer and less time consuming...unprofessionnal, because high current in a poor contact creates HEAT
And the laminations are always placed right side up.
@@quinquiry
Ya I know I worked in the field for 40 years at san diego gas & electric and what the heck are they doing there right ? Alan Thomas
Nice work The wires instead of drop out fuses are scary. Great job of getting that transformer down the pole.
Жесть в том что без каких либо средств защиты. Масло трансформаторное оно при нагреве токсичное!!! Сам электромонтёр поэтому знаю. Отмыть руки после него ох как не легко.
I love the hand chopped yardstick and brown kraft wrapping paper.....Along with the old re-purposed cardboard boxes, Masking Tape, 'n Elmers Glue and impressive clean room winding facilities.....LoL
Соединение шинок в конце видео - топ😁
Без работы товарищи точно не останутся😀
13:15 Провод обмотки нарастили просто скруткой
Я тоже думал, шину кинул, пропаяет! А тут и так сойдёт! Вторичка, дикий ампераж, но нет, там свои законы физики
и тааак сойдёт, неделю поработает и само сплавиться
лох не мамонт не когда не вымрет...
Посмотри на "предохранители" по ВН в начале - странно что вообще не рвануло как следует. Плюс внутри наверное смесь отработанного моторного масла, воды и грязи :)
Соединения хорошие чтобы через месяц опять перемотать.
Yeah dear
Market economy's first principle is,creat demand and then supply 😝😝😝😝😝😝😝😝😝 some transformers ! ! !
Смотать медные шины алюминиевой проволокой это верх мастерства ! ))))
I love how 2 of the 3 fuses on the transformer appear to be just thin guage wire
Makes me wonder how they connected the wires into the high voltage in the first place.
This transformer isn't going to last long as the 11kV windings are not staggered and enameled aluminum wire is used instead of copper...
Es para que no se acabe el trabajo, haces de cuenta que es un transformador desechable para una cantidad de tiempo, no se tal vez 2 o 3 años y así sucesivamente, siempre habrá transformadores que arreglar, me imagino yo!
@@simonsmith2802 not a primary concern there :D
@@simonsmith2802 Oil and paper insulation is common All but dry transformers use that method.
Have you noticed what they used for the insulation between the secondary and the primary winding it would just burst into flames
Это жесть! Все на соплях, ещё нужно скотчем матануть 🤣🤣🤣🤣🤣🤣
Fascinating, yet i am puzzled with the work. Back in the 1980's I worked for a company (Emerson Electric) that built power systems large enough to power small cities. They used to wind their own transformers and the biggest miss I saw in the video is how they spliced their connections. The splices and connections should always be arc welded and not twisted together. Also, some of their insulation methods would lead to a short-lived operation. Much more varnish goes into production transformers. The Iron core would also be bettered with a welded core instead of sheet metal bound by a couple of I-beams. Still I am impressed.
yes I have seen welded connections oxy acetylene welded
This is why the transformer rebuilders are very busy.
Я тоже был поражён тем, как он соединяет медные шины. Это просто недопустимо так делать в высоковольтных сетях!
Seems they are using Aluminum wires. Probably no facility to weld aluminium wires. That is why the long twist. Once the exposed wires start to oxidize, they will fail.
What theya accomplish with the means they have is simply incredible. Elbow greasd and simple tools and voilà ....
You should have soldered the connections on the windings, remember there's a lot of current passing through those windings and twisting them together isn't good enough!
That copper joint 😁😁
На производстве ручных талей можно самым богатым стать.
Что? Техника безопасности? А, не, не слышали!🤣🤣🤣
LoL bro
This was originally a copper transformer with delta connections
U put Aluminium in it with star connections
This is not gonna last long
Explain for us that don't know?
I am saying that this transformer is not gonna work for long
Bcz of Aluminium wire and the star connections
@@ghazielectricworks why
Сколько ручного труда ! Линейка изолятор 🤣
Умение лазить за кокосам тут пригодилось ))) Заказчик Пусть требует Медную Обмотку . . .служить будет дольше .. но скрутки на Алюминии тоже хотябы сваривать нужно .. .32:50 НО ноль у Звезды вообще Чотко замучен ))) ))) это топ !!

Properly protected tranformers are forever. We have one installed in circa 1960 and it is still working (300kVA).

И у меня есть 2 трансформатора 1960 года ))) 3200 kVA , работают на понижение с 35kV на 6 kV
Да, техника безопасности на высоте.
Да ладно, монтажник даже со страховочным поясом был. А рядом мелькали пара ребят в новеньких спецовках. Практиканты по ходу, на балдахин еще не заработали🤣
когда они научатся сваривать все соединения в место скручивания,то трансформаторы будут жить гораздо дольше!
для сварки электричество нужно, а его нет - транс сгорел
Я конечно не спец, но данное видео вызывает некоторую озабоченность :)

Ремонтируют быстро. За день и сделали. У нас бы люди без света сидели месяц а то и больше. Качество конечно никуда не годиться. Вон сколько трансформаторов стоит на ремонте.
Да ладно, не знаю где вы живёте, но на Смоленщине если вышла из строя трансформаторная подстанция сразу туда тянут генераторы, и подключают потребителей. И ремонт ТП производится в любое время суток.
Those workers definitely work hard and know what they are doing good work in very difficult environment. Disconnecting the 11KV feed made me shudder though, thankfully everything was dry at the time.
Yeap
They shut the supply from feeder grid first before disconnecting the 11kva wires. Also they do no work in rain.

Техника безопасности на высоте😂
I had a foreman stomp my toe last week because he didnt think my boots were steel toed. He would love these guys. I like the motorized 2-wheel cart.
Ясно, почему у него во дворе так много трансформаторов...
0:31 - wires instead of fuses...gee, I wonder why the transformer got torched...also, the tower is bent with some of the braces broken. I understand money is tight here, but you can definitely afford to fix this. And to put the meter in a box.
Great work, soldering the splices would be a little better.
Aqui no Brasil tem tanta norma de segurança que as vezes fica até difícil trabalhar , aí os caras de chinelo e sem nenhum equipamento de segurança e tudo braçal.
That reminded me when I was contracted to do a repair in a company work shop and had to wear safety glasses which wear constantly steaming up so I could not see what I was doing, so refused to use them the job did not need safety glasses any way just typical company red tape.
sem falar que o transformador já parecia ser sucata...
Watched my dad rewire many armatures and staters when I was a kid. My older brothers cooked and stripped them and took the copper to the wrecking yard. They got to keep what they made.
Glad to see Canada is so safe
🤣
Ah the sweet smell of PCB transformer oil in the morning
It's good but for the connections. Brazing the connections is better to avoid resistive contacts & hence prevent excessive I2R losses.
Теперь понятно почему у них трансформаторы сгорают 😂😂😂
Вот они трудяги, конечно! При таких допотопных технологиях выполняют ремонты современного (более или менее) оборудования.
ага Была медь намотали люминь Фигня вопрос
@@ALEKSANDOR5 Не было там меди. Все трансформаторы такого размера намотаны алюминием. Исключение может составлять какое-нибудь особо ответственное оборудование или научно-исследовательские установки.
Wow I didn't know that they built their power grid using construction paper and yard sticks :) oh and delicious pcb oil
What a beautiful job. I congratulate you for that repair capacity. You are an amazing person. Thank you for sharing!
Very impressed except I notice there are no older guys doing this..
they are buried in the bushes near this pole.
one guy does all the hard work getting the transformer down and up on the litel transport while everyone just stand and talk beside him,
В конце видео медные шины проволокой обмотал, а я думал хоть горелкой и тугоплавким припоем пройдётся. Разочаровал ты меня Али.
Да хоть оловом!
Didn't know it only took Mod podge, rulers and rubber bands to make such a device. Props to them!
much to learn from these videos yes
This is basically how it's done anywhere... And yes things like masking tape get into the mix in a lot of things you might be surprised would use it 🤣
Fascinating the work involved.
These people are actually as good as a good engineer if we speak about the specific work they are doing. A recent engineer graduate will have a very hard time to fix something like this. And they know a lot better about transformers than recent graduate students.
Did you notice that the guy carefully placed two extra Kraft papers each on both sides of the copper wire join, he knows exactly what he is doing. 👍
In the developed world you wouldn't fix it. You would replace it with another one from the depot and ship the busted one back to the manufacturer for defect investigation or just recycle it.
True. You guys are smart and inventive. You can make something out of nothing.
But please! MIND YOUR HEALTH AND SAFETY for Gods sake!
@@Spookieham Not true, transformers get repaired. I worked in that and it is a huge business.
@@Spookieham We replace the damaged transformer, the old transformer gets rebuilt then put back in stock.
All transformers in the United States that are destroyed get recycled. All transformers that reach their maximum allowed service hours get rebuilt and DERATED. Anyone that thinks an unrepaired and not rebuilt transformer is out back into service should never be a sparky.
As a lineman of almost 40 years that was horrifying,the lack of PPE is criminal.
When you are poor and still need power to look at cat pictures and boobies, PPE is optional I'd wager lol
I am amazed at how they get by with so little. It's impressive.
You may have noticed the lack of a lot more too... 🤷♂️🤣

@@willrobbinson why
Frickin insane safety measures.
You know what. A number of us commentators, me included, deride the "primitive" work methods shown in so many of these videos. However, there is one quality which comes through every time.......their "can do" attitude. Jobs we softies from the Western world would dismiss out of hand, they tackle with unbounded enthusiasm. These guys don't sit on their butt waiting for handouts, or play the perpetual 'victim'. No, these guys are hard working, resourceful and innovative. I salute them.
Thanks
Now how do you know that????
How does this kind of work get done in the west if we ar all softies then?
great,but they obviously never seen OSHA in their lives. this job ( the removal n replace part) is easy for us( I am a retired HV lineman here in the Northeast.)is easy enough on a nice day with a 20' steel tower. Try it at night in the rain on a 45' pole,oh and let's add a bit of wind and maybe 40° to that. And the guys in our refurb shop would have done the rehab in less time with a lot more reliability. NEXT!
@@Mr39036ce your guys would just stand there clueless, completely different world.
Тоже экономят, перешли на алюминиевый провод.
Somethings are universal - at the beginning one guy doing all the work and everyone else standing around and watching!
Монтажник классный, сам снял сам поставил, сам перетащил, остальные стояли смотрели. Нафига так сильно лак для пропитки греть, там хватило бы 60 градусов, эффект был бы лучше, если бы при пропитке вакуумировали.
i guess they are using the smoking hot oil to drive off moisture
Обмотки масляных трансформаторов не пропитывают в лаке. Это была сушка изоляции обмоток в кипящем масле
Ээ, а ничего что он в конце медную шину алюминиевой скруткой прихерачил? Гальваническая пара и всё такое. 😳
не страшно, она лакированная. )) наверное, синяя изолента кончилась.
Lift chain knot tying is seldom taught in Lineman school today!
Cielos, que seguridad tan impresionante.😳
в самом конце он мотал перемычки медной проволокой в лаке! Там, наоборот, нужен хороший контакт, а его не будет.

É impressionante como na Índia eles fazem improvisos pra tudo. Parece que Normas Técnicas passam longe desse local. Mas por incrível que pareça as coisas, no final, funcionam !
As que não funcionam, e as que resultam em acidentes fatais não são mostrados ...
SMUD and PG&E should watch this.
It’s like this country is stuck in the 1920s
The fundamental product as winding was well executed on what I view as limited equipment. Save for perhaps weldment out of reach to site. As for safety, transport, hydralic lift and various process.....well...I am a bit at a loss to describe. Save as lineman (apprentice) I might call "Lurch" in fact managed disconnect and dismantle to ground, subsequent transport operations. *I would say bare bones with a chain hoist and pipe tripod as (site) minimal gear. The transport as very useful conveyance. Again, bare bones.
As for the hot work at barrel, the oil containment as near flame might be well changed to piped steam? But, then again, resources seem lesser and where workers might simply face deficit to understand the hazards. (many) at the underlying oil chemistry and de facto environment shown.
In the end, I'm reminded how tough and resourceful workmen in fact can become. Most with huge patience, good humor and endurance. Still, if offered as service to payment, I would hope some safety might be demanded even if in the simplest of upgrades. I cite native (New Guinea) tribal members to mine haul operators as aptitidue.
