Description

technical field [0001] The invention relates to the field of cable and wire processing, in particular to an aluminum alloy conductor for cables and a preparation method thereof. Background technique [0002] For a long time, copper has been used as a conductor in cables. Its electrical performance and stability have great advantages over other materials before. Therefore, copper has always been the best choice for cables and wires. However, based on the fact that my country has less copper and more aluminum In addition, under the national strategic vision of advocating energy conservation and sustainable development, more economical and more environmentally friendly aluminum materials will become the first choice for cable raw materials. "Replacing copper with aluminum" has become an inevitable trend in the transformation and development of the cable industry. . [0003] With the improvement of power transmission and transformation technology and the development of power tran...
