New Materials Empower Power Distribution Upgrade

To meet diversified power distribution demands of data centers, energy storage power stations and high-end industrial plants, as well as deliver green and low-carbon development goals, the market has realized large-scale mass production of five new types of conductor materials for busbar trunking systems. Breakthroughs have been made in three major technical routes - high-conductivity copper, modified alloys and lightweight composites - to overcome performance bottlenecks of conventional conductors and supply core material support for the full range of busbar products.

For high-end computing and large-capacity power distribution scenarios, two new copper-based conductors are prioritized: T1 ultra-high-purity oxygen-free copper and copper-silver micro-alloy. T1 copper boasts a purity of 99.99% with lower resistivity. Combined with micro-arc busbar structure that mitigates skin effect, it cuts power loss by 2% for busbar systems carrying ultra-large current up to 6300A. Copper-silver alloy conductors withstand long-term high-temperature loads with remarkably reduced resistance drift under high-temperature operating conditions and stable temperature rise at joints, making them suitable for projects with continuous heavy loads such as AI intelligent computing centers and smelting plants. Supported by graphene composite modification technology, the conductors gain greatly enhanced surface anti-oxidation performance. Fire-resistant busbars equipped with such conductors are less prone to softening and melting under fire conditions, effectively extending emergency power supply duration.

To satisfy demands for cost reduction and lightweight design, vacuum hot-rolled copper-aluminum composite conductors and rare-earth high-conductivity aluminum alloy conductors have been launched. Nano-interfacial treatment is applied to copper-aluminum composite materials, integrating the high conductivity of copper and lightweight merit of aluminum. Products with identical current-carrying capacity achieve a 30% weight reduction and a 25% drop in overall material costs. Rare-earth zirconium modified 6063 aluminum conductors feature substantially improved conductivity, while double-sided thickened nano tin plating eliminates the pain point of overheating caused by aluminum busbar oxidation. They are widely adopted for DC busbar systems in photovoltaic plants and industrial & commercial energy storage facilities.

All new conductor materials are produced on standardized tin plating and precision forming production lines with full-process controllability. Each material category targets dedicated application sectors: high-purity copper and copper-silver alloys are specially used for data center main trunk lines and super high-rise buildings, while copper-aluminum composite and rare-earth aluminum conductors serve new energy industries and conventional power distribution in standard factories.

Supported by upstream material innovations, our company will keep pace with technical upgrades and achieve triple improvements in energy efficiency, cost control and safety in busbar trunking manufacturing.
