A method is herein provided for making round electrical cable for use under severe environmental conditions including the step of providing a conductor, coated with a layer of insulating material. A lead sheath is applied over the layer of insulating material and a layer of heat resistant, abrasive resistant, protective material, such as a nylon base substance, is extruded onto the outer surface of the lead sheath. The conductor is then twisted with other similar conductors, through a die, and the bundle of mutually twisted conductors is then encased in a nitrile-base jacketing material.
