PROBLEM TO BE SOLVED: To provide a low voltage drawn insulation wire capable of improving flaw resistance when the wire is dragged during construction, without exfoliation, with ease, of an insulation body even if the wire is dragged during construction.SOLUTION: In an insulation wire 2, an inner layer 6 is formed on a conductor 5 by covering it with a low density polyethylene blended with metal hydroxide, and the inner layer 6 is covered with an outer layer 7 containing high density polyethylene colored in black by blending with carbon black. Two insulation wires 3 and 4 include insulation layers containing inner layers 9 and 14 which cover conductors 8 and 12 with a low density polyethylene blended with metal hydroxide, being colored in various discrimination colors, and containing outer layers 11 and 14 covering the inner layers 9 and 14 with high density polyethylene colored black by bending with carbon black, with a part of the inner layers 9 and 14 to be exposed outside being left out. The insulation wire 2 and the insulation wires 3 and 4 are twisted together to constitute a low voltage drawn wire 1. |
