Summary:PROBLEM TO BE SOLVED: To provide a cable having a self-extinguishing property and producing less smoke. used as an electric cable especially for low-voltage power transmission. or electric communication, or data transmission, or used as a mixed cable for power and electric communication. SOLUTION: This cable has a coating layer 3 based on a polymer substance and a nonflammable inorganic filler, The polymer substance includes a heterophase copolymer having elastomer phases based on ethylene copolymerizing with α-olefin and thermoplastic phases based on propylene, The elastomer phase content is at least 45 wt.% relative to the total weight of the heterophase copolymer, and the heterophase copolymer has substantially no crystallinity deriving from the polyethylene sequences.
