<P>PROBLEM TO BE SOLVED: To provide an insulated electric wire having high insulating characteristics, high scratch resistance, and high flame retardancy. <P>SOLUTION: The insulated electric wire is constituted by forming on a conductor 1 in order a first insulator layer made of PE or polyolefin resin in which volume resistivity after immersion in water for 100 hours is 1×10<SP>14</SP>Ωcm or more, a second insulator layer 3 made of a flame retardant resin composition obtained by blending magnesium hydroxide of 250-350 pts.mass to base resin of 100 pts.mass comprising EVA of 45-55 pts.mass, AEM of 35-45 pts.mass, and SEB elastomer of 5-10 pts.mass, and a third insulator layer 4 made of the scratch resistant composition obtained by blending flame retardant agent of 60-130 pts.mass comprising magnesium hydroxide of 50-100 pts.mass and melamine cyanurate of 10-30 pts.mass to base resin of 100 pts.mass comprising EVA of 60-80 pts.mass, SEEPS of 15-25 pts.mass, AEM of 5-10 pts.mass, and acid modified LLDPE of 5-10 pts.mass. <P>COPYRIGHT: (C)2007,JPO&INPIT |
