　　 Steel cored aluminum alloy stranded wire JLHA1/G2A-185/30-26/7 with complete specifications

　　Characteristics of Steel cored Aluminum Alloy Stranded Wire:

　　1. 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.

　　2. 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, which reduces the load on the tower. Due to the use of high-strength aluminum magnesium silicon aluminum 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.

　　3. Aluminum alloy core aluminum stranded wire is a single material of aluminum substrate, which has no hysteresis loss during AC operation, so its AC resistance under normal load is more advantageous. In addition, because aluminum alloy core aluminum stranded wire is a single material of aluminum substrate, there is no electrochemical corrosion of bimetallic, and it has anti-corrosion function.

　　Application scope of aluminum alloy core aluminum stranded wire

　　1，Aluminum alloy core aluminum stranded wireDue to its advantages of light weight and high current carrying capacity, it is generally used as a new line to replace the original steel cored aluminum stranded wire.

　　Execution standard:

　　IEC61089-1991 Concentric Stranded Hollow Wire

　　GB/T 1179-2008 Round Wire Concentric Stranded Hollow Wire

　　Technical Characteristics

　　1. 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.

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

　　3. 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.

　　The utility model discloses a steel core formed aluminum alloy stranded wire, comprising a steel core composed of steel wires and an aluminum conductor wrapped around the periphery of the steel core. The aluminum conductor comprises multiple layers of aluminum alloy wires, and the aluminum conductor adopts an aluminum alloy wire with a profile structure. Two adjacent aluminum alloy wires are tightly matched and wrapped around the periphery of the steel core This utility model improves the tensile strength of the current carrying element and the deformation of the structure, replacing the traditional circular wire structure with a profile wire structure. On the basis of improving the tensile strength of the wire, it makes the wire have excellent performance such as smooth surface, tight, not easy to freeze, wind resistance, and corrosion resistance for overhead special wires
