1. Significant Cost Advantages and Better Economics
Aluminum is one of the most abundant metal elements in the Earth's crust, abundant in resources, and significantly cheaper than copper. For the same current carrying capacity, the procurement cost of aluminum alloy cables is approximately 30%-40% lower than that of copper cables. This advantage is particularly significant in large-scale power projects, significantly reducing initial project investment.
Furthermore, the lightweight nature of aluminum alloy cables (weighing only 50%-60% of copper cables) reduces labor and equipment costs during transportation and installation, further improving overall economic benefits.
2. Lightweight Design Improves Installation Efficiency
Traditional copper cables are heavy, making installation difficult and time-consuming in complex terrain or at high altitudes. The lightweight design of aluminum alloy cables significantly simplifies handling and installation, making them particularly suitable for long-distance power transmission and urban power grid transformation.
Furthermore, aluminum alloy offers superior flexibility to pure aluminum, and its creep resistance is enhanced through a special alloy formulation, making it less susceptible to breakage or deformation during installation and adaptable to a wider range of complex environments.
3. Strong Corrosion Resistance, Longer Lifespan
Aluminum alloy conductors naturally form a dense oxide film on their surface, effectively resisting corrosion from air, humidity, and chemicals. In highly corrosive environments such as coastal areas and chemical parks, their service life is 10%-15% longer than copper cables.
Some high-end aluminum alloy cables also feature an anti-oxidation coating, further enhancing their aging resistance and reducing the risk of failures caused by environmental factors.
4. Outstanding Environmental Protection, Contributing to Sustainable Development
Aluminum has a recycling rate of over 95%, and smelting energy consumption is only 5% of that of primary aluminum production. In contrast, copper mining and smelting processes impose a greater environmental burden.
Aluminum alloy cables have a significantly lower lifecycle carbon footprint than copper cables, meeting the global "dual carbon" goals for green energy infrastructure and making them a valuable choice for companies fulfilling their social responsibility.
5. Optimized Conductivity, Ensured Safety
Although the conductivity of pure aluminum is only 61% of that of copper, by adding elements such as iron, magnesium, and silicon to form an aluminum alloy and using a compressed stranded structure, its current carrying capacity can reach 78%-85% of that of copper cables. While meeting the same power requirements, performance can be matched by only slightly increasing the cross-sectional area, and safety indicators fully comply with international standards (such as IEC and UL certifications).
