The invention discloses a shell powder-containing silicone crosslinked polyethylene cable material. The cable material is prepared from 70-80 parts by weight of high density polyethylene, 20-30 parts by weight of an ethene-octene copolymer, 12-16 parts by weight of nylon 6, 5-8 parts by weight of viscose fibers, 0.1-0.3 parts by weight of dibutylbis(dodecylthio)stannane, 3-5 parts by weight of nanometer zinc oxide, 3.2-4.4 parts by weight of sodium dihydrogen phosphate , 16-21 parts by weight of styrylethyltrimethoxysilane, 18-22 parts by weight of shell powder, 4-6 parts by weight of hydrogenated castor oil, 40-50 parts by weight of aqueous inorganic aluminum sol resin and a proper amount of water. The cable material has a reasonable formula. The used viscose fibers improve cable material strength and tearing resistance. A net structure obtained by crosslinking of the used styrylethyltrimethoxysilane and the polyethylene compound can prevent oil from permeating and diffusing into the blended molecules so that good obstruction performances are obtained. The cable material with other effective assistants has the advantages of flame retardation and good toughness and can be used in the field of dynamo-electric equipment.
