Re: [TCML] 100kVA trannies as salvage?

["John Forcina" <forcijo10@xxxxxxxxx>]

I have a friend who has a 50kva 7200v pig and it weighs 629lbs.  Those
100kva units must weigh at least 1000lbs.  If you want a general breakup on
how much copper is in them, this is my best guess.  Total weight,
1000lbs-oil=900lbs-can=750lbs-core=350lbs.  You have roughly 350lbs of
copper in there.  If copper sells for $1.50/lb the you come up with a
whopping $525 in copper.  I would still try to get it for $50 because there
is always the chance that they will say yes.   Good luck.
