Mr. Ensign: Regarding the matter of efficiency, so far as I can understand the transformer design, you can make the efficiency what you please if you put the proper bulk in it. If you have to allow air space, you make your transformer that much heavier, and get the same efficiency that you have when you have lowered the insulating space.

Our company builds the self-cooling type, the air-cooled type, the oil-insulating self-cooling type, and the water-cooled, oil-insulated type.
