PROBLEM TO BE SOLVED: To provide a silane cross-linked polyolefin resin composition which is free of Sn, secures rapid and reliable crosslinking and is good in appearance and insulation, an electric wire and a cable.SOLUTION: In a cable, an insulator is an Sn-free silane cross-linked polyolefin composition, and the silane cross-linked polyolefin composition contains 0.1-1 pt.wt. of an alkylated naphthalenesulfonic acid with respect to 100 pts.wt. of a polyolefin. The sheath is composed of an Sn-free polyvinyl chloride composition, and the polyvinyl chloride composition contains 0.1-3 pts.wt. of an alkylated naphthalenesulfonic acid, 30-100 pts.wt. of a plasticizer having a polar group and a nonpolar group and 2.5-8 pts.wt. of a stabilizer with respect to 100 pts.wt. of polyvinyl chloride. |
