Description

technical field [0001] The invention relates to a production technology of an aluminum alloy cable, in particular to a high-performance rare earth aluminum alloy conductor and a preparation method thereof. Background technique [0002] With the rapid development of my country's economy, the great development of the power system, and the large-scale infrastructure construction, the demand for wire and cable in my country has grown rapidly. At present, most of the conductor materials of wires and cables in my country are copper conductors, but due to the shortage of copper resources in my country and the high price of copper, copper conductor materials account for about 70% of the cost of copper wires and cables, resulting in too much cost for manufacturing copper wires and cables; Using pure aluminum conductor material, after long-term use in our country, it is found that the pure aluminum conductor material will undergo large creep after long-term operation or current overloa...
