Abstract
The invention relates to the technical field of cables, and provides a high-strength aluminum alloy power cable. The cable is sequentially provided with an aluminum alloy conductor layer and an outer sheath layer from inside to outside. The outer sheath layer is prepared from the following raw materials in parts by weight: 40 to 50 parts of low-density polyethylene, 20 to 30 parts of ethylene propylene diene monomer, 8 to 15 parts of maleic anhydride grafted ethylene-vinyl acetate copolymer, 20 to 25 parts of modified attapulgite, 10 to 15 parts of nano hydrotalcite, 6 to 8 parts of coated potassium titanate whisker, 1.5 to 2 parts of dicumyl peroxide, 10 to 15 parts of magnesium hydroxide, 3 to 5 parts of zinc borate and 0.3 to 0.5 part of antioxidant 1010. 0.2-0.4 part of dilauryl thiodipropionate, 4-5 parts of a calcium-zinc composite stabilizer and 0.5-1 part of calcium stearate. According to the invention, the flexibility of the cable outer sheath is improved while high strength is ensured, and the heat dissipation performance of the high-strength outer sheath is improved at the same time.
