High heat-resistance resin composition and high heat-resistance insulated cable which uses the same

A high heat-resistance insulated cable, comprising:

• a conductor;
• and
• an insulation for insulating the conductor having a thickness of 0.1 mm to 0.5 mm,
• the insulation comprising a high heat-resistance resin composition comprising:
• where the high heat-resistance resin composition is subject to a thermal treatment at 150° C. for 100 hours,
• a heat absorption amount of the high heat-resistance resin composition which is measured at a melting point thereof by Differential Scanning Calorimetry (DSC) being equal to or less than 45 J/g before the thermal treatment;
• an increasing rate of the heat absorption amount of the high heat-resistance resin composition which is measured at a melting point thereof after the thermal treatment by Differential Scanning Calorimetry (DSC) being equal to or less than 20% as compared to that before the thermal treatment;
• and
• a degree of extensibility thereof being equal to or more than 200% after the thermal treatment,
• wherein the high heat-resistance resin composition further comprises:
• polyester resin;
• PS-polyethylene/buthylene-PS triblock copolymer;
• and
• polyolefin and/or a compound including glycidyl.
