Method of manufacture of electrical wire and cable having a reduced coefficient of friction and required pulling force
First Claim
1. A process for making a finished wire and cable having a reduced coefficient of friction and reduced pulling force during installation, the process comprising:
- 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 at 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 jacket composition comprises;
a predetermined amount by weight of nylon; and
at least 3% and less than 5% by weight of a predetermined amount of amorphous silica, wherein the nylon and silica are polymerized together without a pulling lubricant as an extrudable, pelletized compound;
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;
wherein the extruded nylon and silica of the finished wire and cable reduces the coefficient of friction and reduces the pulling force during installation.
