Hochspannungswiderstandskabel vom Spulentyp zur Unterdrückung von Rauschem

摘要

There is provided a coil type noise suppressing high voltage resistance wire wherein, without applying a releasing agent to the coil core, by reducing the viscosity of the fluororubber in unvulcanized state to a moderate degree, winding work of the resistance wire can be smoothly carried out. On the coil core 12 covered by extrusion coating with a fluororubber mixed with ferrite powder, a resistance wire 13 is wound widthwise, and the coil core 12 on which the resistance wire 13 is wound widthwise is gradually covered with an insulating layer 14, braid for reinforcement 15 and a sheath 16 . The fluororubber is a blend polymer blended as a polymer for reinforcement with an ethylene-vinyl acetate copolymer (EVA) which has compatibility with the fluororubber and is co-vulcanized in vulcanizing. The blend ratio is 5 to 25 % by weight of the EVA to the blend polymer. $$
