Compression Cable

A mass-impregnated pressure cable in which the pressure medium is separated from the insulation by a membrane or sheath. In these external pressure cables, the insulated cores are constructed in the same way as for solid cables. Each core is usually covered with a polythene or thin lead sheath, which serves as a diaphragm. One or more cores are then enclosed in an outer protective covering. See Pipeline Compression Cables and Self Contained Cable.
