PROBLEM TO BE SOLVED: To provide a cable which has a small diameter and is excellent in flame resistance while securing excellent abrasion resistance and sufficient breaking strength without using halogen-based fire retardant.SOLUTION: The cable comprises: a pair of insulation wires 1 which twist each other; an internal sheath 2 made of non-halogen polyurethane covering the circumference of the pair of insulation wires 1; and an external sheath 3 made of a mixture of non-halogen flame retardant polyurethane elastomer and non-halogen flame retardant polyester elastomer covering the circumference of the internal sheath 2. A breaking strength is 300 N or more, and an external diameter is 3.4 mm or less. |
