ABSTRACT OF THE DISCLOSURE An electrical power cable for use with submersible motors, particularly in the high temperature, high pressure environment of relatively deep oil wells, comprises electrical conductors disposed within an ethylene-propylene copolymer or termpolymer jacket. The conductors may be electrically insulated by the jacket compound itself or by individual insulators of butyl rubber, silicon rubber, or copolymers or terpolymers of ethylene and propylene. The jacketed cable is protected by an outer armor formed by a tightly wrapped band of suitable metal. The cable thus formed is flexible, abrasion resistant, and pervious to the gas and nonpolar solvent present in a well environment.
