If you ever wanted to see the process of making a heavy duty transformer in a modern factory try the following video:

Note also the rigorous QA testing of the finished product.
Amazingly they actually work but the efficiency might be on the low side.

Hey! I used to work in joints like that!!!!!!
Check out the rusty roof iron laminations, but mind the fingers! Obviously grain oriented high permiability grade steel!
At least they used actual COPPER building wire for the windings not steel wire like in Chinese trannies..
Love the Hi-Qual insulation used with built in advertising.
Just love the dexterity of the workers and most of it done on the ground.
And that advanced workshop equipment.............although I should not talk when I look at some of the gear in my workshop.
The funny thing is those suckers will probably be working into the next ice age.
Fred.

I am amazed that there aren't more buildings burnt down from electrical fires in India because of this sort of thing. Grossly inefficient transformer design, no grommets, E's and I's bunched and held together with timber, testing by shorting out the secondary terminals - which won't do the half wave rectifier much good and did anyone notice the power indicator blinking after the 'testing' had been completed?
The designer needs to equate himself with crimp lugs too as twisting wires around studs and sandwiching them between nuts doesn't cut it. If the factory owner gave each worker a workbench and stool and set up a proper production line as well as removing the manufacturing bottlenecks, which are also basic electrical design faults, the end product would be more efficient, made in far greater numbers and wouldn't be a hazard to the end user either.
I am assuming India builds its cars the same way, which is probably why few here drive a Tata.

I have not heard anything re Tata going Tata's because of fire; seen others locally made do it.... Might be a case of the regulations of the country they are exported too?

That's because they fall to bits before they get a chance to catch fire.
The scary thing is that mobs like Tata (India) and Geely (China) are buying up more well known and reputable brands. What will become of them over the longer term we are yet to find out.
It was reported the other day that Daimler Benz is now 20% Chinese-owned. Some Mercedes engines are already built there. A typical Merc owner doesn't hang on to their car for that long before replacing it with another later model so long term build quality probably no longer matters.
I live on the North Shore in Sydney. There are German car brands everywhere amongst my Holden. Very few would be more than five years old, yet my car is nudging 19 and the car has been half way around the clock and is on its second engine everything still works including things like electric mirrors and antenna.

Another owner of an old car. My car is 25 years old, still on original engine, runs fine. Of course, there's no electronic screen, airbags, cameras or in-car computers.

At the risk of sounding pedantic, Abdul Brothers from Karachi are from Pakistan, not India.

Yet another owner of an even OLDER vehicle.
A 1990 Toyota Dyna 200 with a fibreglass motorhome body on the back now 31 years old 285,000 kms on the clock and only a 2.4L petrol/Gas motor pulling 4 tonnes of vehicle.
Slow (85-90KPH MAX) and steady and most parts still readily available...body parts a different story though and I will need a windscreen soon as the existing has many stone cracks so that could be fun sourcing one.

MY ex has a Pulsar with 300K plus on the clock. About eight years ago she called the RACV one cold morning because it would not start.
The RAVC mechanic changed the oil on the spot. She never bothered to have it changed until it became tar and impeded the engine from cranking fast enough that particular morning.
Car is still running today, new front universal joints all that was needed for road worthy certificate. Same oil from eight years ago, I imagine.

I know this thread has left the rails with regard to dodgy transformers but in relation to car rego, I put mine in for a pink slip the other day only to find that the RMS did a system upgrade a day prior and messed it up and it's taken until now to fix it. Why don't they do these things over Christmas or Easter when mechanics aren't uploading pinkslips? I guess that is too sensible for bureaucrats to get a grip on.

Some older stuff was made to last. The end of last year I sold the 2001 Mazda it had a 1500 engine that loved chewing up water pumps every 50,000Km and it had friends. So that's the end of Mazda's.
Tractor is 72 it blew the head gasket at the end of 2019; last refit prior 1986. Parts still available. Bottom end, sleeves & pistons still original. Stamped 1951.
MKII Zephyr 1958 First life motor, water pump failed at 99,800 miles, same bearing & seal as Fordson tractor, of the shelf part, pump is cast iron as is the thermostat housing, runs corrosion inhibitor, no corrosion on pump, block or thermostat housing. Charging system had a malfunction recently. New belt (off the shelf) I rotated the generator & voltage regulator out & sorted the wiring issue. They will be overhauled & rotated back in, when the current generator runs out of brushes.
Normal Tractor & Ute schedule is change at 2 years with filter and don't use crap oil. Both are petrol & run oil with a diesel spec. Inside of Tractor engine was free of rust and extremely clean despite the added water. That got a brief run with oil from the Ute after a hot run. That's standard procedure around here for an engine that has blown a head gasket. You swat the oil from a hot good engine (diesel preferred) and us it to scavenge the rest of the water.
Neighbour & his Father bought different model Great Walls they crumbled fast. Drove the Ute one, Zephyr is superior.

Back to the Abdul Bros charger!
What a stunning design!
A truly MULTIPURPOSE charger, it can charge any number, any size, any voltage any type of battery.
No matter if its a Li-Po or a Ni-Mi or a La or any other acronym this baby does the lot!
No need for all those microprocessor laden taper charge voltage regulating lardy dah controllers, you just hook this baby up to the terminals and away it goes! The secret is it has.....wait for it........a RECTIFIER!
AND, while you boil the truck battery up you just clip the optional stick weld leads on and weld up that nasty crack in the chassis.
What more could you want?
( welding sticks not included).
AND, as well as welding, this hero also doubles as an air ioniser, insect zapper, room heater and many many more purposes!
Throw out all those unnecessary modern electronic controlled pieces of equipment in the workshop, you no longer need them as this baby does the lot! Just ring 1-800-123456789 or log onto wwww.abdulbroskarachi123.com to secure yours but hurry only a limited number available!
Sorry about that............ I have been watching too much day time television.......................................
Back on earth, the level of technical design reminds me of equipment available around the turn of the century 1900.
Back then manufactuers were just one step forward from rolling there own lammo steel and smelting and belting their copper wire.
Abduls build quality does need a touch up though.
Fred.

Now that's where the Zephyr & Tractor win. There is no such thing as an obsolete chipset, or the required board is no longer made rendering the thing bin material. Lots of bits in them are still gettable, fit something else, or are repairable.

If this is to work in up country Pakistan it needs to be rugged and capable of working in 40C heat, perhaps in sunshine. Considering the type of insulation on the windings - appeared to be single wire house wire - and the apparent lack of ventilation for the cabinet, it wouldn't last long. It might depend on the power output, and I couldn't quite make out the numbers on the volt and amp meters to work out a power output. There was no maximum current mark on the meter or current rating on the cabinet, so would assume the maximum amp meter number.
