Cable having expanded, strippable jacket

Abstract From the Canadian patent

An electric power cable contains a core and a jacket forming the exterior of the cable. The jacket is formed by extruding a first layer and a second layer over a plurality of concentric neutral elements substantially encapsulating , these elements. At least the first layer is an expanded polymeric material by , having its density reduced through the use of a foaming agent during extrusion. The second layer, which may also be expanded is extruded around , the first layer. The expanded polymeric material makes stripping the jacket easier, minimizes indentations in the cable's insulation layers lightens the , cable, and increases the cable's flexibility.
