Claim 0:
1. A thermoplastic high heat-resistant nylon-coated (THHN) electrical cable having reduced installation pulling force through a polyvinyl chloride (PVC) conduit setup, the THHN electrical cable comprising:
at least one conductor capable of carrying an electrical current through the THHN electrical cable, wherein the conductor is formed at least in part from a metal; and,
a sheath for protecting the conductor, wherein the sheath comprises:
an insulating layer surrounding the conductor and providing electrical insulation to the conductor, wherein the insulating layer is formed at least in part from extruded polyvinyl chloride (PVC); and,
an outer layer surrounding, contacting and forming a coating for the insulating layer, wherein the outer layer further comprises;
an extruded nylon component;
a pulling lubricant provided at an exterior surface of the extruded nylon component that aids in reducing the installation pulling force as the THHN electrical cable is pulled through a PVC conduit setup; and wherein,

the outer layer is both resistant to heat, moisture, oil and gasoline, and provides the THHN electrical cable with the physical characteristic of having an average coefficient of friction against an interior surface of a PVC conduit setup of less than about 0.25.
