ABSTRACT:
An electromechanical tow cable which includes a central strength member comprised of a plurality of yarns of electrically conducting aramid fibers. The electrically conducting central member is surrounded by a dielectric medium on the surface of which is located two or more groups of electrically conducting wires circumferentially separated by electrically insulating sections. An outer electrically insulating jacket forms a protection for the cable. The central conducting strength member may be utilized for the application of a relatively high voltage which utilizes one of the conducting wire groups as a ground return. Another one of the conducting wire groups may be utilized for a relatively lower voltage which may utilize the same conductor group as the high voltage for a ground return.
