　　Characteristics of steel core heat-resistant aluminum alloy stranded wire:

　　 Steel cored heat-resistant aluminum alloy stranded wire overhead transmission lines, as the carrier of power transmission, play an extremely important role in transmission lines. For a long time, overhead lines have mainly used Aluminum Conductor Steel Reinforced (ACSR). In order to achieve safe and reliable power transmission, scientific and technological workers in various countries have been striving to find ideal overhead transmission lines to replace traditional wires, such as steel cored aluminum alloy stranded wire developed to improve strength, all aluminum alloy stranded wire, and aluminum clad steel cored aluminum alloy stranded wire. Aluminum clad steel cored aluminum stranded wire developed to improve anti-corrosion performance, various heat-resistant aluminum alloy wires developed to improve wire transmission capacity and heat resistance, and aluminum alloy used to replace ordinary aluminum wire developed to reduce wire sag. Wait.averageWhen constructing new lines and expanding and renovating old lines, in order to achieve more ideal transmission capacity and fully utilize the towers of old lines, steel core heat-resistant aluminum alloy stranded wire can be used, which can greatly improve the transmission capacity of lines at the same voltage level.

　　 China has been using heat-resistant aluminum alloy wires for more than 10 years As early as 1986, domestically produced 1440mm2 steel core 58% conductivity heat-resistant aluminum alloy stranded wire (NRLH58GJ) was used as the busbar in a 500kV substation, achieving significant technical and economic benefits With the development of power grid construction and the need for transmission capacity, the application of heat-resistant aluminum alloy wires has become one of the effective ways to improve the current carrying capacity of wires, and has been increasingly used in power grid construction. Currently, the application status of heat-resistant aluminum alloy wires in domestic power grid construction and the comparison of electrical energy losses.
