　　Overhead carrying current aluminum alloy core aluminum stranded wire JL/LHA1-21/220 national standard quality

　　Application of aluminum alloy core stranded wire:

　　 Aluminum alloy core aluminum stranded wire is an overhead conductor made by using high-strength aluminum alloy wire as a reinforcing core and concentric twisting with hard aluminum wire.

　　Aluminum alloy core aluminum stranded wire is lighter in weight than ordinary steel core aluminum stranded wire with the same outer diameter, and the tension to weight ratio is basically the same, with less load on the tower. Due to the use of high-strength aluminum magnesium alloy core with 52.5% IACS in its reinforced core, the wire resistance is significantly reduced, and the current carrying capacity is higher than that of ordinary wires.

　　 Aluminum alloy core aluminum stranded wire is a single material of aluminum substrate, which has no hysteresis loss during AC operation. Therefore, its AC resistance under normal load is more advantageous. In addition, due to the fact that aluminum alloy core aluminum stranded wire is a single material of aluminum substrate, it does not have the electrochemical corrosion of bimetallic and has anti-corrosion function.

　　Application: Aluminum alloy core aluminum stranded wire, due to its advantages of light weight and high current carrying capacity, is generally used as a new line to replace the original steel core aluminum stranded wire, known as the second-generation wire product.

　　Execution standard:

　　IEC61089-1991 Concentric Stranded Hollow Wire

　　GB/T 1179-2008 ? Circular concentric twisted frame empty wire

　　ASTM B524

　　Technical Characteristics

　　 Lightweight, with a tensile strength to weight ratio consistent with steel cored aluminum stranded wire. The reinforced core adopts high-strength aluminum alloy wire with a tensile strength of 295MPA-315MPA, a conductivity of 52.5% IACS, and a wire tension to weight ratio equivalent to steel cored aluminum stranded wire.

　　The wire loss is small. Using all aluminum materials effectively reduces DC resistance and has no hysteresis loss.

　　Corrosion resistance and long service life. The reinforcing core of the wire is made of high-strength aluminum alloy stranded wire, which has no electrochemical corrosion of bimetallic and has anti-corrosion function. The service life of the wire is long.Aluminum alloy core stranded wire follows the standard GB/T1179-2017.
