　　 Lightweight steel core heat-resistant aluminum alloy stranded wire NAHLGJQ-1440/120 600-1600 expansion conductor

　　 Steel core heat-resistant aluminum alloy wire is a composite wire with aluminum clad steel core as the reinforcing wire and heat-resistant aluminum alloy as the carrier fluid. It is a new type of energy-saving wire. The reinforced core is replaced by aluminum clad steel core instead of traditional steel core, reducing its chemical corrosion and increasing its service life;The outer layer is made of heat-resistant aluminum alloy material, and the working temperature not only reaches 150℃Above, its conductivity has increased to60%IACSThis greatly improves the carrying capacity of the wires.

　　Product performance

　　Compared with traditional steel cored aluminum stranded wires, aluminum clad steel cored heat-resistant aluminum alloy wires have advantages such as high operating temperature, good heat resistance, high current carrying capacity, good corrosion resistance, and good creep performance. The characteristic of heat-resistant aluminum alloy wire is that it allows for high working temperatures. Compared with steel cored aluminum stranded wire of the same cross-section, the current carrying capacity can be increased50%In the process of line expansion and renovation, especially in narrow areas of the line corridor, it is only necessary to replace heat-resistant aluminum alloy wires with similar cross-sectional specifications without replacing the iron tower to achieve the goal of increasing the transmission capacity. This is very suitable for places that are restricted by land use or require more manpower and financial resources to update routes.

　　The widespread application of heat-resistant aluminum alloy wires can greatly save the cost of power construction and has enormous social and economic benefits. At present, China's power grid construction is in a period of rapid development. The application of new technologies and equipment such as heat-resistant aluminum alloy wires has practical significance for improving the level of power grid planning, design, construction, and operation.
