Title: Filling compound for multi-wire conductor of an electrical cable and cables including such compound

Abstract

An electrical power transmission cable is described including a conductor surrounded by insulation material and a filling compound filling any interstices in the conductor. The filling compound comprises: a polymeric compound which has a 100 gram needle penetration value between 50 and 100 tenths of a millimeter at 25/sup 0/C; and particles of a water swellable material contacting the polymeric compound, the particles having a particle size not greater than 200 microns. A method of making an electrical power transmission cable having layers of conductive wires thereby providing an outer layer of wires and an inner layer or layers of wires is described comprising: bringing together the wires while applying flowable polymeric compound around at least the wires forming the inner layer or layers; putting particles of a water swellable material having a particle size not greater than 200 microns into contact with the polymeric compound which has been applied around the wires forming the inner layer or layers; extruding a layer of semi-conductive material around the wires; and extruding a layer of insulation around the layer of semi-conductive material.
