The outer semi-conducting layer of the terminal area where it possesses the main leadership body (1)

摘要

PROBLEM TO BE SOLVED: To provide a method for connect the return path conductors of DC coaxial cables with no risk of thermal damage on the external semiconductive layer and the main insulation layer of a cable, or the external semiconductive layer and the reinforcing main insulator at the joint when the return path conductors are connected by welding.;SOLUTION: A thermal buffer layer 25 is provided on an external semiconductive layer 4 in the region of a return path conductor 5 performing connection by welding, and the return path conductor 5 is connected by welding on the thermal buffer layer 25. The thermal buffer layer 25 is formed by winding up a semiconductive cushion tape from the external semiconductive layer 4 of a cable to the external semiconductive layer 24 at the joint such that the outside diameter becomes uniform.;COPYRIGHT: (C)2008,JPO&INPIT
