Patent ID: 7488893

Claim:
A flexible, heat-resistant, non-halogen electric wire, comprising a conductor fabricated by twisting a plurality of strands and an insulator covering the conductor, wherein: the diameter of each of the plurality of strands is within a range of 0.12 to 0.31 mm; the insulator includes a resin material including an ethylene copolymer including 25 to 40 weight percent of vinyl monomer, which has an oxygen element in a molecular structure thereof, other than vinyl acetate, as a main constituent, which occupies 50 weight % or more of the resin material and also includes an elastomer as an accessory constituent, which occupies another part of the resin material; the main constituent and the accessory constituent are mixed to prepare the resin material; subsequently, the resin material and a metallic hydroxide are mixed to prepare a cladding material; the conductor is covered with the cladding material; and the cladding material is then bridged to form a cross-linked resin.
