Description

technical field [0001] The invention relates to the field of wires and cables, in particular to a heat-resistant aluminum alloy wire with high conductivity. Background technique [0002] With the continuous development of my country's economic construction and the continuous growth of power demand, the demand for cables as carriers of electric energy transmission is also increasing. At present, most of the cable conductors used in China are steel-cored aluminum stranded wires and steel-cored aluminum alloy conductors. , These conductors are heavy in weight and high in resistance, and the existing copper cables have low ampacity, low heat resistance, and copper resources are in short supply. [0003] In addition, the existing cable cannot realize the communication function, and another communication line needs to be set up to meet the communication function, resulting in repeated wiring. The temperature rise of the wires during the operation of the cable cannot be monitored, ...
