Abstract

The invention discloses a flame-retardant long-term ultraviolet aging resistant lapped aluminum alloy power cable which comprises an insulating cable core, packing, a refractory mica tape lapping layer and a PVC sheath, wherein the insulating cable core consists of an aluminum alloy conductor and an insulating layer; and the PVC sheath is prepared by mixing the following components in parts by weight: 100 parts of PVC resin, 15-20 parts of an ethylene propylene diene monomer, 10-15 parts of a heat-resisting reinforcing agent, 5-10 parts of polyisobutene, 20-30 parts of calcined clay, 1-3 parts of stearic acid, 10-15 parts of paraffin oil, 1-2 parts of a thermal stabilizing agent, 1-3 parts of a light stabilizer, 1-2 parts of an antioxidant, 5-8 parts of a toughening agent, 0.5-1 part of an ultraviolet protecting agent and 2-4 parts of molybdenum trioxide. The flame-retardant long-term ultraviolet aging resistant lapped aluminum alloy power cable disclosed by the invention is excellent in ultraviolet aging resistance, good in flame resistance and long in service life.

Description

technical field [0001] The invention relates to an aluminum alloy power cable, in particular to a wrapping aluminum alloy power cable which is flame retardant and resistant to long-term ultraviolet aging. Background technique [0002] At present, the leading product in the wire and cable industry is copper core cable, which has high raw material price and shortage of resources, and copper alloy has some defects, such as high cost and poor mechanical properties. Aluminum ore resources and rare earth resources are relatively abundant. In order to alleviate the tension of copper resources, using aluminum alloy and other materials to make high-performance cables can be a good solution. The electrical conductivity of aluminum alloy is 61.8% of copper IACS, the most commonly used reference material, and the ampacity is 79% of copper, which is better than the standard of pure aluminum. Under the same volume, the actual weight of aluminum alloy is about one-third of that of copper....
