ABSTRACT:
A method of laying a cable system in which the cable guide tube has internal ribs alternating in helical direction and of dimensions and number designed for particular cable radii and cross section to allow the cable, whether a single cable or a bundle or cables to be blown through about 2000 m of the tube with 90 kN of force or to be pulled by a strand through the conduit with a force of 2.5 kN over a stretch of 1400 m without damage to the cable.
