Method For Making High-Temperature Winding Cable

Abstract

A method for making a high-temperature winding cable is winding a tinned copper line around a coaxial line, signal lines and power lines after being assembled together, lapping the rim of the tinned copper line with a packaging material of Polytetrafluoroethene, and then, extruding an insulating layer of thermoplastic material on the rim of the packaging material, and finally, extruding an outer cover of fluororubber on the outer rim of the insulating layer, thereby forming a cable; sintering the cable; winding the sintered cable clockwise around and fixing it to a iron bar; cooling the wound cable; and finally, taking down the wound cable from the iron bar by rewinding it counterclockwise so as to obtain a high-temperature winding cable. The winding cable so made is not melt, damaged, and retains elasticity after the impact of high temperature 260 C.
