ABSTRACT:
A method for reducing the friction between a conduit and a cable while the latter is pulled into the conduit consists of locating a layer of balls on the surface of the conduit or cable before laying. The balls have a diameter much lower than that of the cable, typically of the 0.1 to 1 mm range. The balls may be adhered to the cable as it progresses into the conduit, using for instance electrostatic forces. The balls may as well be blown into the conduit to form a carpet before the cable is forced into the tube. In both cases, friction is reduced whatever the angular portion of the conduit which is contacted by the cable during pulling.
