括して照射架橋を行ってもよい。In the drawing, a first insulating layer 2 made of crosslinked polyolefin is applied around the outer periphery of a conductor 1 made of a single or stranded copper conductor plated with soot, nickel, silver, or the like. The first insulating layer 2 was formed to have a thickness of about 0.1 to 1 mm. Examples of crosslinked polyolefins include homopolymers of olefin monomers such as polyethylene, polypropylene, poly-1-butene, polyisobutylene, and poly-4-methyl-1-peretene, ethylene-ethyl acrylate copolymers (EEA), and ethylene-ethyl acrylate copolymers (EEA). Vinyl acetate copolymer (EVA)
, ethylene-propylene copolymer (EPR), ethylene-propylene-diene! Crosslinked polyolefins such as EPDM, copolymers such as ethylene-butene-1 copolymer, ethylene-butene-1-diene copolymer, or blend polymers of two or more of these are used. The crosslinking method here includes a method in which a composition in which an appropriate amount of an organic peroxide such as dicumyl peroxide or t-butylcumyl peroxide is added to the above polyolefin is extrusion coated, and the above polyolefin is crosslinked by heating. After coating by extrusion, crosslinking is carried out by irradiating with an electron beam, and a silane compound such as vinyltrimethoxysilane, vinylrutriethoxysilane, vinyltris(β-methoxyethoxy)silane and an organic peroxide are added to the polyolefin. This method includes kneading to form a silane-grafted polyolefin, extrusion coating the silane-grafted polyolefin, and then crosslinking in air or water. In the case of electron beam irradiation, irradiation crosslinking may be performed all at once after applying two or three layers.
