摘要:
A process for manufacturing finished wire and cable having reduced coefficient of friction and pulling force during installation, includes providing a payoff reel containing at least one internal conductor wire; supplying the at least one internal conductor wire from the reel to at least one extruder; providing the least one extruder, wherein the at least one extruder applies an insulating material and a polymerized jacket composition over the at least one internal conductor wire, wherein the polymerized jacket composition comprises a predetermined amount by weight of nylon; and at least 3% by weight of a silica providing a cooling device for lowering the temperature of the extruded insulating material and the polymerized jacket composition and cooling the insulating material and the polymerized jacket composition in the cooling device; and, reeling onto a storage reel the finished, cooled, wire and cable for storage and distribution.
