Isn't nice how capitalism works ? You get stuff from these 'slaves' basically because they're paid very shit wages for what they do, for your comfort. That's reality btw, I'm not insulting anyone here. That's how the world works based on this capitalism bs.
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.
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

Whilst these are rather small transformers, the construction requirements are generally similar throughout all scales. Look how much time and effort goes into just the one; now, consider how much materials / time / effort goes into the very HV "Supergrid" systems, and consider the far, FAR longer lead times for replacement should they be significantly damaged, as we saw in the US Metcalfe attack in 2014 ($15 million in damage over 20 minutes).
our military budget costs us 1.5 million a minute, 93 million a hour or 2.2 billion a day. so while 15 million in 20 minutes sounds like a lot, when compared to real wastes of money...it's not even a drop in a bucket. clearly the time and effort required to build these transforms is no joke, still the cost of that attack isn't much in the grand scheme of things. also seems kinda crazy that they wouldn't have replacements ready....but i suppose that shouldn't be unexpected with how lax regulations are for companies.
@@rocksfire4390 Its the time requirement and limited amount of manufacturers. Lead times are insane right now. Almost 2 years for any transformer order if you can even get a manufacturer that will take an order.

Interesting that they don't do any measurements during the assembly, when any errors would be relatively easy to fix. They only measure when the transformer is already assembled and filled with oil, when any issue is most difficult to fix.
From what I can see the primary is 3 phase 3 wire delta. The secondary is 3 phase 4 wire Y. In my area the primary voltage would be 34,400 volts and the secondary would be 277/480 Y with a grounded neutral 60 hertz. I dont know what nation you are from but what would the primary and secondary voltages be on this transformer you show in the video?? Hear in the states we have what they call a pad mounted transformer thats 2,500 kva thats dead front that sits on the ground and you dont need a fence or vault to put it in. It sits next to the building its serving.
The complete transformer may handle kilovolts but the potential difference between the individual windings is so low it can be insulated by only a coat of varnish and some very thin cloth.

Ok..so who's doing the quality control...geez
cant believe, that this transformer works. they made it with ancient tools
My whole body cringed when I saw that 25mm wrench used on a nut that was closer to 23mm at 6:39.

Given their country's power infrastructure, these transformers are suitable for use. As for exports, quality needs to be further improved.
