Thats essentially how it's done.. Although in modern factories they use machines for rolling, and instead of shit on of what I'm assuming is cable they use full aluminum sheets
I'm not an electricity power engineer, but it looks like each low voltage phase (secondaries) consists of 2 windings in parallel. I guess this is simply because a single winding would be to stiff to wind on by hand. The high voltage primaries looks also to have 2 windings each as well, one with taps, the other without. In operation at the lightest loads, the transformer primary would have just the phase windings without taps connected to the incoming supply. As an automatic 'on load tap changer' detects secondary voltage drop with increasing load , tapped windings are switched in parallel to restore the secondary voltage, i.e. automatic tap changing takes place without interruption to the supply.
@@CubicSpline7713 aluminum does actually find use in large distribution transformers (it's good for foil windings and especially for resin cast unit), but copper definitely is a better conductor. Oil soaked paper (or cardboard as you put it) is the norm for transformer insulation, and isn't a "low quality Chinese" thing
Amazing crafstmanship & industrial skilled workers, but it's sad they're not being provided with PPE (personal protective equipment) such as respirators (masks) or gloves when handling the solutions, torches and solder as well as the painter.
Actually some of those welds sucked! They will likely fail under pressure and expansion/contraction due to heating/cooling cycles. Where is the quality control for this company?

Сам работаю на трансформаторном заводе, но до такого "технологического уровня" нам конечно далеко. Особенно умиляет покраска бака из краскопульта и пропитка катушек в корыте из бочки. Жаль не показаны изготовление бака и резка ламелей для магнитопровода.
У нас примерно такая же технология ремонта. Катушки на подобном же станке мотают. Медные обмотки сейчас редкость, алюминий везде. Ну и шайбы граверные подкладыают. А так одень в спецовки "Россети" и за своих принять можно. Стенд по испытанию транса даже лучше нашего выглядит
@@Pikulev_Evgeniy Ну, технология намотки похожа на нашу, только по низкой стороне мотаем единой лентой, а не пучком шин. Станки у нас не новые, но с программным управлением.

RickFox below had the correct concept, only a few missing washers, many metal chips down into the windings, painter spraying chromate or zinc paint with no mask, and using the old style paper & jute insulation (which actually works good in oil), and no pretesting before final assembly. We did this also, and it was the PCB oils which made these designs durable. Later, some of us got cancer. In the US, this would be a crime against humanity, but no worries over there.

This is likely not General Electric or ABB. I don't see too many production workers in factories I have been to in the United States wearing flip-flops.
9:15 на шайбах сэкономили. как и у нас примерно также лепят. раз уже приходилось переделывать транс, где отводы прикрутили как попало, прямо на пластиковую панель. когда по уму надо было сперва болты прикрутить к пластику на гайку как надо. Было : Болт - пластик - отвод - шайба и гайка. в итоге отгорело. Стало: Болт - пластик - шайба - гровер. потом Гайка - шайба широкая- отвод - шайба широкая - гровер - гайка. только так стало надежно работать и провод перестал греться.

Great video. Just natural sounds. No bullshit music.
looks like a very serious craftwork. Amazing to see, how a handful people build such one.
Great craftmanship. Very nicely build coils and assembly. A few missing washers and spring washers on the connections.

Transformer production facilities are the perfect place for flip flops. I always say
No, No. Those are safety flip-flops!

In the West, this would be done in a clean room... These guys are way ahead of us in cost and quickness.
That is a clean room by Indian standards. Notice - no sand on the floor.
@@CHMichael and no fire inside the building.
These also don't last a fraction of the time that western transformers do before they go nuclear. lol
I bet it doesn't last half as long as a western one would.

Es maravilloso la fabricacion de Transformadores gracias por compartir
Thanks for the tutorial, it's much faster than any other method I came across.
Pretty nice,thank you soooo much
The tap-offs on the primary side really needed some washers with lock washers. You don't want anything to start arcing on the inside.
Studies show split lock washers don’t help.

Should be a picture of Tesla hanging in the shop. They could look at it and say "Thanks for this backbreaking job".
No way I’d energise that on the grid
