I have pole xmfrs that can be pulled out of their original tank. I recase
them in a steel case 18 x 18 x 19 inches high. I use a phenolic top for
input output. Weight is reduced from 300 lbs to 110 lbs and you can run
any range from 3 kVA up to 20 kVA with these bullet proof beasts.
Contact me off list if interested.
