The core is used to manufacture conductive cores for wires and cables, overhead transmission and distribution stranded conductors, windings for electrical equipment, and other applications. It serves as a critical medium that connects power generation, transmission, and end-use applications, and is widely applicable across multiple sectors, including smart grids, new energy, rail transit, and high-rise buildings.
Aluminum-alloy conductor wire is a core conductive material for power transmission, electrical equipment, and specialized applications. It is manufactured from high-purity aluminum as the base metal, with alloying elements such as magnesium, silicon, copper, and rare earths added, and then processed through precision techniques including melting, refining, continuous casting and rolling, drawing, and annealing. Its primary applications include the production of conductor cores for wires and cables, overhead transmission and distribution stranded conductors, and windings for electrical equipment. As a critical medium that links power generation, transmission, and end-use applications, it is widely suited to diverse sectors such as smart grids, new energy, rail transit, and high-rise buildings. It simultaneously delivers outstanding electrical conductivity, mechanical strength, and weather resistance, thereby meeting the power industry’s need for efficient, energy-saving, and green upgrades in line with the “dual carbon” goals.
Applicable Application Scenarios
Leveraging a diversified alloy system, extensive product specifications, and outstanding performance, our products are widely used in core sectors such as power transmission, electrical equipment, new energy, and specialized applications, covering the full spectrum of scenarios from basic distribution to high-end ultra-high-voltage systems. Specifically, these include:
Power transmission sector: Used in the manufacture of overhead aluminum alloy stranded conductors for power transmission and distribution (such as ACSR/ACAR conductors) and conductor cores for medium- and high-voltage power cables, covering low- and medium-voltage distribution systems up to 10 kV, high-voltage transmission systems at 35 kV and above, and 1,000 kV ultra-high-voltage transmission projects. These applications are aligned with grid construction initiatives by State Grid Corporation of China, China Southern Power Grid, and other grid operators, accounting for 68% of total consumption in this sector in 2023.
Electrical equipment sector: Used in the manufacture of electrical components such as transformer windings, enameled wires, and motor lead wires; suitable for industrial motors, transformers, distribution cabinets, and other electrical equipment, as well as high-voltage wiring harnesses for new-energy vehicles and cable assemblies for charging stations.
New energy sector: transmission lines and associated cables tailored for photovoltaic, wind power, and energy storage systems, as well as internal cabling within new energy power plants, with consumption reaching 280,000 tonnes in 2023 and projected to exceed 450,000 tonnes by 2025.
Special-application sectors: the 5xxx series is used for power transmission and distribution cables in harsh environments such as marine settings, chemical plants, and high-humidity conditions; the heat-resistant series is employed in high-temperature power plants and ultra-high-voltage converter stations, as well as in rail transit, high-rise buildings, and mining operations. These products are exported to Vietnam, Indonesia, Europe, and other countries and regions, thereby supporting the development of overseas power infrastructure.
