Electrical cable having crosslinked insulation with internal pulling lubricant
Abstract:
Electrical power cable having a reduced surface coefficient of friction and required installation pulling force, and the method of manufacture thereof, in which the central conductor core, with or without a separate insulating layer, is surrounded by a sheath of crosslinked polyethylene. A high viscosity, high molecular weight silicone based pulling lubricant or fatty acid amide pulling lubricant is incorporated by alternate methods with the polyethylene to form a composition from which the outer sheath is extruded, and is effective to reduce the required pulling force on the cable during installation.
