Like those flat rate boxes from the Post Office say "If it fits It ships!"
I can't say, never had one apart. They have iron cores wrapped in copper. One big enough to feed your house weighs 400 LBS.I've often wondered what it is inside transformers that makes them so heavy? I've these things go 600 tonnes in what appears to be dimensions that are relatively not much larger than a couple of shipping containers.
Askarel was not used by the time I was graduating high school in 1973. Transformers are still filled with oil, but no longer contain PCBs.Don't a lot of them have a cooling liquid too? Old ones were full of PCB's and needed special care to remove them.
Copper and iron wrapped as tight as you can make it is what is inside them, plus the case and fins are a good portion of an inch thick steel, everything is heavy. Of course utility transformers may have aluminum windings but that is only for cost, all the other heavy stuff remains.I've often wondered what it is inside transformers that makes them so heavy?

Yup, that's what it does with lighting strikes....Yeah, I'd be very surprised too. There would be a lot of bombs just waiting to go off if something went wrong like a lightning strike or downed wires or a short. I certainly couldn't see them listed as meeting ULC standards.
