Abstract
The invention discloses a creep-resisting aluminum alloy cable including an aluminum alloy conductor. The aluminum alloy conductor comprises, by mass, 0.5 to 1.3% of Fe, 0.1 to 0.5% of Ni, 0.1 to 0.6% of Cr, 0.01 to 0.02% of La and the balance being Al and unavoidable impurities. The aluminum alloy conductor includes two to four wire rods wrapped with duplex-PVC films respectively. The wire rods are arranged into a wire harness. Then the surface of the wire harness is wrapped with a layer of copper foil. The outer surface of the copper foil is wrapped with a high-strength nickel-coated fiber film. A vulcanized silicone rubber layer is wrapped on the outer periphery of the high-strength nickel-coated fiber film in an extruded manner. First, Fe in a comparatively high proportion is added into aluminum alloy, so that the creep-resisting performance of the creep-resisting aluminum alloy cable is improved substantially. Second, by adding Ni and Cr into the aluminum alloy, the creep-resisting performance is further improved. In addition, by utilizing the copper foil, the creep-resisting performance of the creep-resisting aluminum alloy cable is further enhanced. And the addition of the high-strength nickel-coated fiber film for wrapping improves the creep-resisting performance of the creep-resisting aluminum alloy cable to a higher degree.
