Abstract:
1. A wire, comprising: a conductor extrusion-coated with a covering layer, the covering layer comprising a resin composition including a silane-crosslinked polyethylene as a main component provided by crosslinking a polyethylene selected from the group consisting of an ethylene-hexene copolymer and an ethylene-octene copolymer in presence of a silanol condensation catalyst and water, the polyethylene being graft-copolymerized with a silane compound by a free radical generating agent, wherein the polyethylene has a density of 0.87 to 0.91 g/cm wherein the silane compound is included not less than 2 parts by mass relative to 100 parts by mass of the polyethylene, wherein the resin composition includes silicon detected by a fluorescence X-ray at a rate of not less than 0.3 mass % and has a gel fraction of not less than 70%, wherein a mass ratio of the silane compound to the free radical generating agent is not less than 35 and not more than 150, wherein Gel fraction=(mass of gel remaining after extraction)/(mass of resin composition before extraction)×100(%), and wherein the covering layer has a load elongation of not more than 175% and a post-cooling permanent elongation of not more than 15% in JIS (Japanese Industrial Standards) C 3660-2-1-9 hot set testing conditions of an air temperature of 200 degrees C., a load of 20 N/cm
