False. I have bought, inspected and done start up on US manufactured transforms in Medium Voltage Systems in the past year (and the past couple decades). There are multiple US factories building these, larger and smaller transformers.
They are not all built in the US, but there is a significant amount built here.
seriously? that’s good to know, for the longest time the only stories i’ve seen are that all the large and midrange tramsformers are made’,overseas now. who makes them here still? i’d like to know so i can remember it the next time this comes up, as i think a lot of other folks have the same info i did.
