Abstract
The invention discloses a silver-copper-coated aluminum alloy cable including a cable core. The cable core includes an aluminum substrate, a copper coating and a silver coating. The diameter of the aluminum alloy substrate is 0.2 to 3.2 mm. The aluminum alloy substrate comprises, by mass, 0.51 to 1.25% of Ni, 0.23 to 0.79% of Mg, 0.005 to 0.062% of Ag, 0.08 to 0.75% of Cu and the balance being Al and unavoidable impurities. The aluminum substrate is covered with the copper coating and the copper coating is covered with the silver coating. According to the invention, the aluminum substrate has good performance in electric conduction and signal transmission and is low in mass, so that convenience is made for cable erection or other purposes. Besides, since the aluminum alloy substrate is wrapped with the copper coating and the silver coating, the electric conduction performance of the outer layer of the silver-copper-coated aluminum alloy cable is improved further.
