Abstract
An energy transmission cable is provided with a lubricating coating layer upon its outer covering, such as an outer jacket or outer insulation of the cable, is permanent on the outer covering, provides for a coefficient of friction between the cable and a cable engaging surface that is less than the coefficient of friction between the cable without the lubricating coating layer and the engaging surface and which has an outer surface which is dry, non-tacky and water insoluble. The features of the lubricating coating layer remain substantially unaffected upon exposure to the environmental and physical conditions associated with storage and installation of an energy cable.
