Abstract
The present invention is directed to enhanced compositions that facilitate the pulling of cables through conduits. In one embodiment, the composition comprises a sufficient amount of boron nitride, which, upon application onto the cable surface, allows the cable to be pulled faster and/or with less force through the conduit than without the boron nitride present. The invention further relates to a method for pulling cables through conduits by applying an effective amount of boron nitride composition onto the cable surface. Lastly, the invention relates to an apparatus for distributing a cable-pulling composition comprising a block of boron nitride onto a cable as it is being pulled through a conduit.
