ABSTRACT:
A lubricating composition and method are disclosed for lubricating the inner wall of a hollow conduit and the outer surface of an insulated flexible electrical conductor installed in the conduit. The lubricating composition is a powder comprised of the following powdered ingredients: lubricant such as talc; drying agent such as a micron-mesh silica; surfactant such as calcium stearate; odorant such as sassafras; and colorant such as a nontoxic food or cosmetic dye. The lubricating method first includes the step of blowing a quantity of a powdered lubricating composition into a hollow conduit resulting in the deposition of powdered lubricant on the inner wall of the conduit. In the next step of the method, an insulated flexible electrical conductor is inserted into the pre-lubricated conduit whereby powdered lubricant on the inner wall of the conduit rubs off onto the outer surface of the insulation of the electrical conductor thereby lubricating the insulation as it advances through the conduit.
