The invention discloses a high-flexibility cable material for high power. The high-flexibility cable material is prepared from, by weight, 1-2 parts of antiager D, 2-4 parts of nano calcium carbonate, 3-6 parts of polypropylene, 2-4 parts of petroleum wax, 2-3 parts of zinc oxide, 1-2 parts of antiager 4010, 1-2 parts of lead oxide phosphite hydrate, 3-5 parts of zinc borate, 4-5 parts of dilauryl thiodipropionate, 4-6 parts of ethylene bis stearamide, 6-8 parts of trioctyl trimellitate, 3-5 parts of sorbitan fatty acid ester, 40-50 parts of acrylic rubber, 2-4 parts of nanometer magnesia, and 8-12 parts of filler. According to the cable material, antiager D and antiager 4010 are adopted simultaneously, so that the heat resisting, antioxidation and bending, winding and fracturing resisting capacity of products are remarkably improved; meanwhile, sorbitan fatty acid ester and other materials are added, so that the cable material is high in flexibility and wide in market prospect.
