I have just tracked down a source of GE transformers at very reasonable
Here's the info:
"GE has the best pricing and features (50/60 HZ is a "beefier design than a
The 5 KVA version is aluminum windings with dimensions of : 10.75 W X 14.5 H
X 11.2 D and 115 Lbs. Technically the aluminum has better electrical
characteristics; The amount of aluminum is equal to 120% of copper.
GE pricing is: 3 KVA general purpose single phase wall mounted- $ 244.19
each net plus tax
5 KVA - $ 339.93
each net plus tax"I have not heard of 50 / 60 Hz trafos and I don't believe
that al has better electrical characteristics than cu but it sure is a lot
less dense. I have seen a 5 KVA for sale that weighed 160 lbs.
Al cabling is used as a substitute for cu and I know it works quite well.
But in trafos?
Comments really appreciated.
