RE: [TCML] 100kVA trannies as salvage?

At the current salvage rates for copper you will be hard pressed to get
them for anywhere close to $50. I'm betting that the meth-heads will
offer them more than that.
At $3 + a pound for copper, and assuming that the transformer weighs at
least 500 pounds, guesstimating that 200 pounds of that is copper, you'd
be looking at $600 worth of copper alone in each transformer. 
I am guessing (and probably being conservative) on all of those weights,
as my direct experience with pole pigs is pretty limited, but those
sound like fairly reasonable assumptions. 
So if you can pick them up for $50 you are a lucky man!

Subject: [TCML] 100kVA trannies as salvage?

I saw a couple of 100 kVA pole transformers in the yard of a local HVAC
contractor a while back.  At least they are marked with the '100' on the
side.  They are huge, maybe 5' tall (it has been a while, need to go
back and look at them again), and must weigh a lot.  I was thinking of
calling them and offering them salvage value for them, or $50.  I think
they are really too big for me to use, as they are much bigger than the
one feeding my house and about 5 others!  

But they may be worth dismantling...  Does anyone know how big the cores
are (if they are indeed 100kVA) and if it might be worth placing it in a
smaller container and using at lower power, or would that be too
