Abstract

PURPOSE:To improve a heating process in a method of manufacturing bridged polyolefine cable by forming a continuous insulation cover with an extruder such as to reduce oxidation of conductor by heating to as great an extent as possible while at the same time precluding decomposition residue at the time of bridging and further better the heating effect.
