PROBLEM TO BE SOLVED: To provide a flame-retardant coated cable provided with an insulator having a high heat-resistant temperature and excellent work execution performance, and a sheath providing excellent flame-retardance without generating hydrogen halide gas when burned and having excellent work execution performance. SOLUTION: The material used as an insulator is a silane-crosslinked polyolefin resin composition which has the hardness(JISA) of or more 90, the 5% elasticity of or less 5.7 Mpa, and the constitution of the resin component wherein low-density polyethylene is of or less than 90 pts.wt. in the resin component 100 pts.wt., and the remainder is ethylene copolymer. And the material used as a sheath is a non-halogen heat-retardant polyolefin resin composition which has the hardness(JISA) of or less 90 and the constitution of the resin component wherein ethylene acrylic acid ethyl copolymer(EEA) is of or less than 90 pts.wt. in the resin component 100 pts.wt., and the remainder is ethylene copolymer except for the low-density polyethylene and/of EEA. |
