    (54) Winding-type high-voltage resistant, resistive cord for preventing noises


    (57) There is disclosed a winding-type high-voltage resistant, resistive cord for preventing noises which comprises a fiber bundle (11), a core (12), a metal small-gage wire (13), a removal layer (15), an internal layer (16), an insulating layer (17), a braid (18), and a sheath (19), wherein the core (12) is formed by immersing the fiber bundle (11) in a fluorocarbon rubber coating containing fluorocarbon rubber filled with carbon and ferrite and regulated by a solvent which is MEK to impregnate the fiber bundle (11) therewith, and the internal layer (16) is made mainly of polyethylene (PE) similar to the insulating layer (17). The core (12) is not removed from the fiber bundle (11) during extrusion of the internal layer (16) which has good adhesion to the insulating layer (17), which prevents lowering of resistance to voltage due to corona discharge. The winding-type high-voltage resistant, resistive cord ensures sufficient resistance to voltage if a high voltage is required.
