Definitions

  • a high-tension electric cable comprising a conductor surrounded by a plurality of layers of oil impermeable insulating tape of synthetic plastic material, each of said layers being formed by a single thickness of said tape, at least one oil impermeable, continuous filament of synthetic plastic material which is thin relative to the thickness of said tape disposed intermediate and in contact with each of said layers and the next layer and separating each of said layers from the others throughout their lengths, said filament being disposed in a predetermined ordered arrangement throughout the length of said cable with at least portions of its periphery separated from other portions thereof and from the adjacent tape to provide lengthwise and circumferential fluid passageways between the adjacent layers, each of which passageways extends from one end to the other end of said cable, and an insulating oil filling said passageways.
