Converting laid electric cable to accept new transmission lines involves moving melting head through cable with tubular push/pull element with electrically isolated leads for heating power

摘要

The method involves melting the distance holders by introducing heat and pulling the inner conductor (2) out, whereby a heated melting head (5) is moved through the cable with a tubular push/pull element (7) with at least two mutually electrically isolated leads through which the electrical energy for heating the melting head is passed. Independent claims are also included for the following: an arrangement for implementing the method.
