REINFORCED UTILITY CABLE AND METHOD FOR PRODUCING THE SAME

摘要

A reinforced 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 (30) to mechanically reinforce the utility transmission line (12), selecting a polymer treated with a catalyst to encase the strands of filament (30) and the transmission line (12), pulling the strands of filament (30) and the transmission line (12) encased in the treated polymer through an elongated protrusion die (38) to form an electrically insulated and reinforced utility cable (72), 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 (38) 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 (72).
