Abstract：

Based on the CATV coaxial cable practice in continuous extrusion cladding and analyses in its reasons for burning,this paper presents the method in protecting the cable core from being burnt by means of using “the sheath of the cable core” and “the device of cooling heat by spraying water”.Here we also present the calculating methods of designing the sheath of the core to protect the core from being burnt by convex die and the device of cooling heat by spraying water to protect the core from being burnt by aluminum tube.
