Gansu hot selling steel core aluminum alloy stranded wire JLHA1/G1A-500/35 processed steel core heat-resistant aluminum alloy stranded wire

Description :

　　JLHA1/G1A-500/35 direct sales manufacturer, Aluminum Conductor Steel Reinforced (ACSR), with high-strength steel wire as the core and aluminum alloy wire twisted on the outer layer;

　　2. Aluminum Conductor Alloy Reinforced (2006), Vol. 34， Light alloy processing technology LAFT 5, also known as ACAR, has an aluminum alloy core and an outer layer of twisted electrical round aluminum wire;

　　3. All Aluminum Alloy Conductor (AAAC), all segments are composed of homogeneous aluminum alloy.

　　In order to solve the above technical problems, the present invention provides a method for manufacturing steel core aluminum alloy stranded wire with high conductivity, high strength, and large cross-section. The method is characterized by the structure of the steel core aluminum alloy stranded wire and the processing technology of the steel core aluminum alloy. The steel core aluminum alloy stranded wire consists of two parts: LHA2 high-strength aluminum magnesium alloy round wire carrying current on the outer ring and GIA high-strength galvanized steel wire reinforcing element on the inner ring. The LHA2 high-strength aluminum magnesium alloy round wire and GIA high-strength galvanized steel wire are twisted into steel core aluminum alloy stranded wire by a twisting machine. The diameter of the steel core aluminum alloy stranded wire is 43.54mm, with a diameter tolerance range of 0.44mm, The steel core aluminum alloy stranded wire is a multi-layer structure, from outside to inside, consisting of an outer layer of aluminum alloy wire, an outer layer of aluminum alloy wire, an inner layer of aluminum alloy wire, 12 layers of steel wire, 6 layers of steel wire, and a center root of steel wire. The aluminum alloy wire that constitutes the outer layer of aluminum alloy wire, the outer layer of aluminum alloy wire, and the inner layer of aluminum alloy wire is LHA2 high-strength aluminum magnesium alloy round wire, with a diameter of 4.84mm. The steel wire that constitutes the 12 layers of steel wire, 6 layers of steel wire, and the center root of steel wire is G1A high-strength galvanized steel wire, with a diameter of 2.90mm;

　　The preparation process of LHA2 high-strength aluminum magnesium alloy round wire includes:

　　1. Testing of high-strength aluminum magnesium alloy rods: The raw material high-strength aluminum alloy rods are inspected before production to ensure that the product is in good condition, with a smooth surface and no defects,

　　2. Wire drawing: (1) High strength alloy round wires are arranged neatly, without any collapse or loose circles caused by wire pressing. (2) During the wire drawing process, the surface of the high-strength alloy round wires is smooth and free of scratches
