Abstract

This electric power cable, and method of making it, relate to high voltage cables with solid extruded insulation, and the life of the cable is lengthened by protecting the insulation from localized voltage stresses which cause emission of electrons into the insulation. An emission shield is used between a semi-conducting conductor shield and the insulation that surrounds the conductor shield and preferably, for higher voltage cables, an emission shield is used between the outside of the insulation and a semi-conducting insulation shield.
