Aluminum-magnesium-silicon alloys are the most used aluminum alloys in wires and cables. They are 6101 and 6201 alloys, and the state is T1 and T4. In 2020, the tensile strength of this alloy is 150MPa-220MPa, and the specific resistance is 0.034 Ω·mm2/m-0.0360Ω·mm2/m, the conductivity is equivalent to 50.0% IACS-47.9% IACS, and it is widely used in the field of overhead lines and ordinary wires. The consumption of this kind of aluminum alloy in the world exceeds 5000kt, and the consumption in China is expected to exceed 1600kt, accounting for more than 30% of the total consumption. Russia is developing nanomicrostructure wire aluminum alloys with a tensile strength of 320MPa-370MPa and an electrical conductivity of 57.2% IACS-56.1% IACS (International Annealed Copper Standard)
Aluminium Wire Cable 1350-H19
For a long time, aluminum cables are mostly made of 99.5% industrial pure Aluminium wire cable1350-H19 AAC 8MM. A variety of composite AAC aluminum stranded wires are mainly used in low-voltage lines and substation connection lines; AAAC stranded aluminum alloy core wires are mainly used in low, medium and high voltage lines and UHV overhead wires; core wires It is ACAR stranded wire of aluminum-magnesium-silicon alloy high-strength wire and industrial pure Aluminium wire cable1350-H19 AAC 8MM, and the number of strands depends on the design; ACSR stranded wire, the steel core wire is electroplated, and the outer layer is one or more layers of industrial pure cold drawn Aluminium wire cable1350-H19
In the initial production of aluminum cables, 8000 series aluminum alloys were used. Alcoa has done a lot of work in developing conductor aluminum alloys, with the first 8000 series alloy patented in 1972, followed by AA8030 alloy in 1973 and AA8176 alloy in 1975. Their mechanical properties are equivalent to those of copper, marking the dawn of a new era of aluminum cables.
