A self-supporting cable, more particularly a vertical riser, borehole, dredger and mine shaft cable is disclosed. The self-supporting cable comprises a cable core, a jacket surrounding the cable core and having one or two diametrically opposed sections of increased thickness, and at least one supporting member totally embedded in each jacket section of increased thickness and disposed parallel to the longitudinal axis of the cable. The supporting member preferably consists of wire ropes made of plural elementary strands wound around a central strand, each strand comprising plural individual wires twisted together.

Self-supporting cable

A power cable comprising three insulated power conductors helically stranded together, at least two grounding conductors located in the outer interstices between the power conductors and an extensible ground check conductor also located in the interstices between the power conductors or at the center. The ground check conductor includes a plurality of metallic wire strands helically wound together in a short lay in the same direction of lay, and extensible non-metallic materials separating the metallic wire strands for substantially eliminating direct friction between the groups of metallic wire strands during flexing and twisting of the cable.
