WikiAnswers - Why is a power transformer so heavy

What a guy....I tried searching for the same thing and all I got was stuff on bleedin' robots! Didn't even say what voltage they worked on.

Your transformers are called isolation transformers the input voltage is 230v and output is 110 v. There is a primary and secondary winding which is copper wire they are isolated from each other and the voltage is developed with the magnetic field. The copper windings are wrapped around an iron core which is very heavy. Larger transformers for hotels eg weigh several tonnes.

They do have sand in them to dissipate heat, then epoxy is poured on top.
