ALUMINIUM BUSBAR

• Aluminium is only 1/3 the density of copper, making aluminium busbars significantly lighter while maintaining the same current-carrying capacity.
• This reduces the overall weight of equipment, which is crucial in aerospace, rail transit, and automotive industries, improving energy efficiency.
• Transportation and installation are easier and more cost-effective due to reduced material weight.

• Although aluminium's conductivity (35~61% IACS) is lower than copper (100% IACS), increasing the cross-sectional area can achieve comparable electrical performance while reducing costs.
• High-purity aluminium (such as 1350-grade aluminium) provides excellent conductivity, making it suitable for high-current transmission.
• In applications like power distribution and data centers, aluminium busbars offer an efficient and cost-effective alternative to copper busbars.

• Aluminium naturally forms a dense oxide layer (Al₂O₃) on its surface, preventing further oxidation and corrosion.
• Suitable for humid and high-salinity environments, such as coastal power transmission systems and renewable energy installations like wind and solar farms.
• Additional anodizing treatment can enhance corrosion resistance, making aluminium busbars even more durable in harsh conditions.

• Aluminium has a thermal conductivity of approximately 235 W/m·K, slightly lower than copper’s 400 W/m·K, but still offers excellent heat dissipation.
• Its high surface-area-to-volume ratio allows for faster cooling and reduced temperature rise, ensuring the safety and stability of power equipment.
• This is particularly beneficial for high-power electronic devices such as data centers, industrial power systems, and renewable energy inverters.

• Easily cut, punched, bent, drilled, and welded, making it highly customizable for different electrical equipment needs.
• Suitable for extrusion, rolling, drawing, and casting, allowing the production of various aluminium busbar shapes, including solid, hollow, and multi-layer busbars.
• Commonly used in switchgear, battery connection busbars, and busway systems, offering flexibility in design and manufacturing.

• Aluminium is 100% recyclable, with a high recycling rate, contributing to sustainability and reducing environmental impact.
• Aluminium production requires less energy compared to copper, aligning with global trends towards green energy solutions such as solar farms and wind power stations.
• The use of aluminium busbars in electric vehicles (EVs) and renewable energy applications supports energy efficiency and environmental protection efforts.

• Aluminium is significantly cheaper than copper, typically costing 30% - 50% less, making it an economical alternative.
• Suitable for large-scale power transmission projects, data centers, rail transit, and electric vehicles, where cost efficiency is critical.
• Lower installation and maintenance costs, as aluminium’s lightweight nature makes transportation and assembly easier.

• The mechanical strength of aluminium busbars can be enhanced through alloying (such as 6061, 6101 aluminium alloys), improving wear resistance and durability.
• Aluminium busbars maintain good mechanical stability under high-current surges and vibration, reducing the risk of mechanical failure.
• Widely used in industrial busway systems, power transformers, and battery connection busbars, where long-term durability is required.
