Abstract: To reduce resistance change due to heat and external force, the noise prevention high-voltage resistance wire comprises a non-metallic reinforcing core wire; a conductive composite including gaseous phase growth carbon fiber, in particular; and at least one insulating layer. The gaseous phase growth carbon fiber is obtained by thermal decomposition of hydrocarbon compound with a catalyzer within a reducing atmosphere. Further, the conductive composite further comprises preferably conductive carbon powder such as conductive carbon black or graphite.

Abstract: A high tension feeding cable, includes:a body of cable which has a high tension core for supplying a high tension current, and an inner covering layer provided on the outer surface of said high tension core, cylindrical terminals, attached to said cable body, for connecting the high tension core to mating electrical apparatus, said cylindrical terminal having a connecting section which connects the inside and outside of the cylinder, said cylindrical terminal being attached to said cable body so as to have the connecting section positioned in the neighborhood of the end surface position of said cable body, and terminal caps, provided on the end sections of the body of cable with the cylindrical terminal, for protecting said cylindrical terminals and further for connecting the high tension feeding cable mechanically to mating electrical apparatus.

Abstract: An electromagnetic wave-shielding material is disclosed. The material is comprised of one or more electromagnetic wave-shielding layers and one or more surface layers. The shielding layers are comprised of a thermoplastic resin, an aluminum or aluminum alloy and electrically conductive carbon black. The surface layers are comprised substantially of thermoplastic resin. The proportion of the carbon black and aluminum in the shielding layer are from 5 to 50% by volume and 5 to 50% by volume, respectively, provided the total proportion of the carbon black and aluminum is 10 to 60% by volume. The difference in solubility parameter between the thermoplastic resin of the surface layer and the thermoplastic resin of the shielding layer is 3.0 or less. The material has superior mechanical strength and electromagnetic wave-shielding properties.
