1. Aluminum alloy cables offer significant cost advantages and superior economic efficiency, with procurement costs approximately 30%-40% lower than copper cables. This advantage is particularly pronounced in large-scale power projects, significantly reducing initial 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 enhancing overall economic efficiency. They are especially suitable for long-distance power transmission and urban power grid upgrades. Aluminum alloys are more flexible than pure aluminum, and their creep resistance is enhanced through a special alloy formula, making them less prone to breakage or deformation during installation and adaptable to more complex environmental requirements. 2. A dense oxide film naturally forms on the surface of aluminum alloy conductors, effectively resisting corrosion from air, humidity, and chemical media. In highly corrosive environments such as coastal areas and chemical industrial parks, their service life is 10%-15% longer than copper cables. Some high-end aluminum alloy cables also employ anti-oxidation coating technology, further enhancing their anti-aging capabilities and reducing the risk of failures due to environmental factors. 3. Aluminum has a recycling rate of over 95%, and the energy consumption for smelting is only 5% of that for primary aluminum production. Aluminum alloy cables have a significantly lower carbon footprint over their entire lifecycle than copper cables, meeting the requirements for green energy infrastructure under the global "dual carbon" goal and becoming an important choice for companies to fulfill their social responsibility. 4. Pure aluminum has only 61% the conductivity of copper, but by adding elements such as iron, magnesium, and silicon to form aluminum alloys and using a compressed stranded structure, its current carrying capacity can reach 78%-85% of that of copper cables. Under the premise of meeting the same power demand, only a slight increase in cross-sectional area is needed to achieve performance matching, and safety indicators fully comply with international standards.
