  • Electrical cable with semi-conductive outer layer distinguishable from jacket
    Patent number: 9064618
    Abstract: An electrical power cable has an outer semi-conductive layer extruded around and in contact with an outermost layer of a cable jacket. The jacket may have a plurality of polymeric layers. The semi-conductive layer is distinguishable from the outermost layer of the jacket immediately underneath it by at least color and possibly also texture. The distinguishable characteristics between the semi-conductive layer and the outermost layer of the jacket decrease the risk of inadvertent damage to the jacket when removing the semi-conductive layer for jacket integrity tests.
