Abstract

A method for drawing a cable which inherently lacks tensile strength into cable channels or cable pipes includes providing a tensile yarn skin on the end of the cable before the step of drawing the cable into the channels or pipes. The yarn skin can either be a net hose or a spin-wrap applied onto the cable. One application of the method is the connection of the cable incoming at a terminal tower to a switching center or exchange.
