The aluminum clad steel core heat-resistant aluminum alloy conductor is a new type of energy saving conductor, which is made of aluminum clad steel core as the strengthening core and heat-resistant aluminum alloy as the fluid carrying composite conductor. The reinforced core is replaced by the aluminum clad steel core instead of the traditional steel core, which reduces its chemical corrosion and increases its service life. The outer layer is made of heat-resistant aluminum alloy material, its working temperature is not only above 150 degrees, but also its conductivity is increased to 60%IACS, which greatly improves the carrying capacity of the wire.
Compared with the traditional steel reinforced aluminum conductor, the aluminum clad steel core heat resistant aluminum alloy conductor has the advantages of high temperature, good heat resistance, large current carrying capacity, good corrosion resistance and good creep property. The characteristics of heat Aluminum Alloy wire is the biggest allowable working temperature is high, compared with the same cross section ACSR, load flow can increase more than 50%, in line expansion transformation process, especially in the narrow line corridor area, heat Aluminum Alloy wire only need to replace the similar section size, do not need to replace the tower can achieve increasing supply the purpose of capacitance. This is very applicable to the limits of the use of the land, or the need to spend more manpower and financial resources to update the line.
