Patent ID: 8701277

Claim:
A method of installing an electrical cable through angled building conduits or passageways through internal sections of walls, ceilings, conduits, rafters or joists in a manner that reduces the amount of force required for such installation, said method comprising: (a) selecting a finished electrical cable having an outermost extruded protective jacket of preselected material surrounding a conductor core, the cable of the type in which a preselected lubricant has been internally combined with the preselected jacket material in connection with the extrusion, and prior to the completion of formation, of the extruded jacket, the lubricant having been effective to migrate through, or permeate, the jacket to be available at the exterior surface of the jacket, and reduce the amount of force required to install the cable through the angled building conduits or passageways through the internal sections of walls, ceilings, conduits, rafters or joists, at the time the cable is to be installed; and (b) installing said cable in the building conduits or passageways without need of adding any additional external lubricant to the exterior surface besides said preselected internal lubricant.
