Electric Cables

April 28, 1938

Cross section of a three-conductor gas-filled cable rated 15 kilovolts, 800,000 circular mils.

The three small channels which convey the gas and equalize pressure are designed to "leak", so that the nitrogen actually is in direct contact with and saturating the impregnated paper insulation.

This cable is of the type and rating now being used by the Consolidated Edison Company of New York and the Yonkers Electric Light and Power Company for [the] city.
