a method and apparatus for producing a reinforce a conductor of a utility transmission line is provided by selecting an electrical or communication conductor for a desired utility , selecting a plurality of strands of filaments to mechanically reinforce the utility transmission line , selecting a polymer treated with a catalyst to encase the strands of filament and the transmission line , pulling the strands of filament and the transmission line encased in the treated polymer through an elongated protrusion die to form an electrically insulated and reinforced utility cable , maintaining an elevated temperature gradient along the die to control the physical property of the polymer as the polymer catalyze , bending the cable in reversed directions after emerging from the protrusion die during completion of the catalyzing and during cooling to ambient temperature to avoid the occurrence of a permanent set in the catalyzed polymer , and coiling the newly formed electrically insulated and reinforced utility cable .
