PROBLEM TO BE SOLVED: To provide a non-halogen multilayer insulation wire excellent in abrasion resistance, hydrolysis resistance, flame resistance, heat resistance, low smoking property, low toxicity and insulation resistance at high temperature, and especially adapted to EN standard (European standard).SOLUTION: A non-halogen multilayer insulation wire 1 contains a conductor 10, an inner layer 20 coated by a polyolefin resin composition containing high density polyethylene and either of an ethylene ethyl acrylate copolymer having the content of ethylene acrylate of 9 to 35 mass% or an ethylene vinyl acetate copolymer having the content of vinyl acetate of 15 to 45 mass% in a mass ratio of 50 to 90:50 to 10 on the conductor 10, and an outer layer 30 coated by a polyester resin composition containing 100 pts.mass of a base polymer containing a polyester resin as a main ingredient, 50 to 150 pts.mass of a polyester block copolymer, 0.5 to 5 pts.mass of a hydrolysis inhibitor, 0.5 to 5 pts.mass of an inorganic porous filler, and 10 to 30 pts.mass of magnesium hydroxide over the outside of the inner layer 20. |
