Different internal construction, external cooling fins, etc..
My pig is mostly oil. Pigs designed to step down high voltages
are not built like a transformer that steps down a lower voltage
but handles more input current. I can pick my pig up and move it
without too much trouble.
... If all else fails... Throw another megavolt across it!
