(57) [Summary] [Purpose] To provide a polyolefin-insulated electric wire capable of preventing deterioration due to copper damage even at high temperatures and greatly extending the heat-resistant life. [Structure] 0.05 to 10 parts by weight of a heavy metal deactivator, and 0.1 to 20 parts by weight of a mixture selected from magnesium hydroxide, aluminum hydroxide, calcium hydroxide and 100 parts by weight of polyolefin. And a conductor is extruded and coated on the conductor. |
