Patent ID: 8809684

Claim:
An insulated wire comprising: a wire conductor; and an insulation coating formed on the wire conductor by extrusion coating a resin composition, the insulated wire being heat treated at 250° C. or higher after the extrusion coating of the insulation coating, the resin composition being a mixture of a polyphenylene sulfide-based resin (A) and a polyamide-based resin (B), a ratio of parts by mass of the resin (B) to that of the resin (A) being not less than 5/95 and not more than 30/70, wherein the resin (B) includes at least nylon 46, wherein the insulated wire exhibits a partial discharge inception voltage of 1800 V or more when a thickness of the insulation coating is 150 μm, and wherein an adhesion property between the insulation coating and the wire conductor is such that a peel length is 2 mm or shorter under a sudden tensile test described in JIS C 3003.
