NON-HALOGEN FLAME-RETARDANT ELECTRIC CABLE

摘要

PROBLEM TO BE SOLVED: To provide a non-halogen flame-retardant electric cable using a non-halogen flame-retardant resin composition excellent in terms of oil resistance and terminal workability.SOLUTION: In a non-halogen flame-retardant electric cable equipped with: a conductor; one or multiple insulating layers formed by coating a non-halogen flame-retardant resin composition on the outer circumference of the conductor; and a sheath formed by coating a non-halogen flame-retardant resin composition on the outer circumference of the outermost insulating layer positioned on the outermost side of the insulating layers, the non-halogen flame-retardant resin composition constituting the outermost insulating layer and the sheath includes: a base polymer including either an ethylene-vinyl acetate copolymer having a vinyl acetate content of 25 mass% or above or a polyethylene exhibiting a melting point peak of 115 to 140°C according to the differential scanning calorimetric measurement method; and 150-300 pts.mass of a metal hydroxide with respect to 100 pts.mass of the base polymer, and the sheath and the outermost insulating layer each yield a mass variation ratio of 420% or less after immersion within xylene heated at 110°C for 24 hours.
