There is an empirical relation between kVA and pounds of iron for most
big power transformers (sadly, I can't find the book with it just now).
At the least, the oil alone will weigh several hundred pounds.  If I had
to guess, based on other HV equipment, I'd say you're looking at
1000-2000 pounds, minimum.
