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.

Description

technical field [0001] The invention relates to the field of transmission cables, in particular to a silver-copper-clad aluminum alloy cable. Background technique [0002] Copper conductor wires and cables are currently the most important conductive wires. They are used in various fields of power and signal transmission. Copper conductor wires and cables have excellent electrical conductivity. However, as the market copper price continues to rise and fluctuate, copper raw materials can no longer fully meet the market demand, which brings great cost expenses to a large number of wire and cable companies that mainly use copper wires. Therefore, it is necessary to seek a method that can It is a problem to be solved at present to have the effect of a copper conductor and to have a cheap conductor. Contents of the invention [0003] In order to solve the above-mentioned problems, the present invention aims to provide a silver-copper-clad aluminum alloy cable, which has good co...
