ABSTRACT:
A coil type, noise suppressing high voltage resistor wherein, without applying a releasing agent to the coil core, the adhesiveness of the fluorocarbon polymer in its unvulcanized state is reduced sufficiently so that unwinding of the unvulcanized core, followed by winding of the resistance wire, can be smoothly carried out. On the coil core covered by extrusion coating with a fluorocarbon polymer mixed with ferrite powder, the resistance wire is helically wound. The coil core to which the resistance wire has been applied is then covered in sequence with an insulating layer, a braid for reinforcement, and a sheath. The fluorocarbon polymer is a blend polymer mixture including a reinforcing polymer, preferably an ethylene-vinyl acetate copolymer, which is compatible with the fluorocarbon polymer and can be co-vulcanized therewith. The blend ratio is 5% to 25% by weight of the EVA, based on the total mixture.
