Abstract

An electric cable 11 is manufactured by extruding a layer of electrically insulating material 13 around an electric conductor 12 to form an electrically insulated core. An intermediate layer of electrically insulating material 14 is then extruded around the core. Two such insulated cores with their intermediate layers 14 are laid up together a sheath 15 of electrically insulating material is extruded around the intermediate layers 14 and the insulated cores. The intermediate layer 14 is predominantly of a material which is incompatible with the material of the sheath so that the sheath does not form a bond with the intermediate layer and the sheath can easily be stripped away from the cores when preparing the ends of the cable for electrical connection to electrical components. In other embodiments the intermediate layer is incompatible with the core insulation so that the intermediate layer comes away with the sheath when the sheath is stripped. The intermediate layer may also be extruded over the insulated cores after they have been laid up together. <IMAGE>
