Abstract: A high strength, lightweight electrical cable having a center strength wire rope member and a plurality of shielded and insulated conducting wires arranged around the center strength member is disclosed, the conducting wires being shielded through the use of a spirally wound layer of conducting material and being cushioned through the use of a soft insulation layer and a plastic filler interposed between the center strength member and the conductors. The conducting wires are formed in bundles and are spirally wound around the center insulator and strength member. A sheath consisting of an open braid of nylon strands secures the conductor bundle, and the entire assembly is jacketed by means of an extruded layer of polyurethane which penetrates into the nylon braid, thereby providing a strong waterproof shield for the conductors. The center strength member is torquebalanced to avoid twisting and imparting rotational movement to a suspended load member.
