As the core conductive component of controlled fusion devices, our company’s liquid-cooled DC busbar for controlled fusion is custom-built for high-power pulse/DC power supply systems in tokamaks, stellarators and other fusion devices. It serves as the core hub for ultra-high-power power transmission that ensures stable, efficient and safe operation of fusion devices, supporting the transition of controlled fusion from laboratory research to engineering and commercial applications.

 

Positioned around high current carrying capacity, high-efficiency heat dissipation, ultra-low inductance and extreme environment adaptability, the product adopts high-purity copper alloy conductors and special high-temperature-resistant insulating materials, integrated with a one-piece forced liquid-cooled channel design. It enables stable current transmission from tens of thousands to hundreds of thousands of amperes, and its current density is several times higher than that of conventional busbars under the same volume, effectively solving the power supply challenges of compact space and high heat flux in fusion devices.

 

To date, the product has been adapted to major national fusion engineering projects including EAST, HL-2A/M and CFETR (China Fusion Engineering Test Reactor). It has also been successfully applied in fusion-related projects in France, with deep participation in Sino-French international cooperation in the fusion field, demonstrating the product’s world-class technical strength. We provide customized design, R&D and manufacturing services according to customer requirements, offering reliable technical performance to deliver core support for breakthroughs in controlled fusion technology.
