A method of forming at least a portion of a cable comprises providing at least one conductor, extruding at least an inner layer of polymeric insulation over the at least one conductor to form a cable conductor core, embedding a plurality of conductors into the inner layer of the cable conductor core, and extruding an outer layer of polymeric insulation over the cable conductor core and the plurality of conductors and bonding the inner layer to the outer layer to form the cable and provide a contiguous bond between the inner layer, the conductors, and the outer layer, wherein embedding comprises heating a one of the inner layer and the conductors prior to embedding the conductors into the inner layer.
