ABSTRACT:
A high voltage overhead electrical transmission cable in which an electrical conductor is eccentrically disposed in a water permeable electrically conductive jacket in electrical contact with the jacket to create a chamber therebetween. A layer of high water-sorbing material, preferably water swellable and insoluble gel-forming polymer, is disposed in the chamber. In this system, water falling on the surface of the jacket permeates through it for absorption by the sorbing material to reduce corona losses.
