A conductor for an automobile is provided. The conductor is configured by compressing a plurality of surrounding wires that surround a central wire. Individual wires of single materials are combined in various combinations. Materials from which individual wires are formed in one embodiment are one of stainless steel, copper or copper alloy. Materials from which individual wires are formed in another embodiment are one of stainless steel, aluminum or aluminum alloy.

Electric wire for automobile

To provide a non-crosslinked flame-retardant resin composition delivering excellent heat resistance without deteriorating over a long period of time, as well as possessing sufficient flame retardancy, mechanical properties, flexibility and workability, and an insulated wire and a wiring harness using the same. The non-crosslinked flame-retardant resin composition includes (B) a metallic hydrate, (C) a hindered phenolic antioxidant, (D) a sulfurous antioxidant, and (E) a metallic oxide in (A) a non-crosslinked base resin which includes a propylene resin containing 50 wt % or more of propylene monomer. It is preferable to utilize an imdazole compound as the ingredient (D) and an oxide of zinc as the ingredient (E). In addition, the composition is used as an insulated covering material for a non-halogenous insulated wire, which is used in a wire bundle of the wiring harness.

A conductor for an automobile is provided that exhibits the characteristics of slender structure, improved strength and reduced weight. The conductor is configured by compressing a plurality of surrounding wires that surround a central wire. Individual wires of differing materials are combined in various combinations to achieve the slender structure, improved strength and reduced weight. Materials from which individual wires are formed in one embodiment are one of stainless steel, copper or copper alloy. Materials from which individual wires are formed in another embodiment are one of stainless steel, aluminum or aluminum alloy.

A cable and cable system is provided having a conductor and an insulation layer on an outer circumference of a conductor. The insulation layer is impregnated with a medium-viscosity insulating oil that has a viscosity of 10 centistokes (cst) to less than 500 cst at 60&deg; C. The insulation layer includes an insulating tape that may be one or a combination of composite tape having a polyolefin resin film laminated with a kraft paper on both its sides and an insulating tape including a polyolefin resin film. The cable includes a metal sheath provided on an outer circumference of the insulation layer, and a reinforcing layer formed on an outer circumference of the metal sheath. The reinforcing layer reinforces the metal sheath by absorbing hoop stress exerted on the metal sheath. The cable system includes a submarine-portion cable and a land-portion cable, an oil stop joint box, and an oil feeding tank. The oil stop joint box connects the submarine-portion cable to the land-portion cable, and the oil feeding tank is connected to the land-portion cable which feeds the medium-viscosity insulating oil to the land-portion cable.
