High power Laminated BusBars: a key technology to solve the problem of heat generation in power transmission

Laminated Copper BusBar, also known as laminated busbar, is composed of multiple layers of conductive copper foil or aluminum foil alternately stacked with insulation material, and formed into an integrated structure through high temperature and high pressure molding. It is optimized from the source of heat generation and has significant temperature control advantages. In terms of low resistance design, the Laminated BusBar for Mersen adopts a multi-layer conductor parallel structure, effectively increasing the conductive cross-sectional area and significantly reducing DC resistance and Joule loss; At the same time, the thickness of each layer of conductor is controlled within the skin depth to make the current distribution more uniform and suppress local overheating at high frequencies. In terms of low inductance characteristics, the Laminated Flexible BusBar tightly overlaps the positive and negative busbars, allowing the current and magnetic fields to cancel each other out. The distributed inductance is only 1/10~1/100 of the traditional scheme, effectively reducing reactive power loss and switching loss, and indirectly reducing heat generation. In terms of efficient heat dissipation, the flat structure of the Laminated Copper Bar has a larger surface area and much better heat dissipation conditions than circular cables. It can directly adhere to the heat dissipation structure to achieve rapid heat conduction and maintain the overall temperature rise at a lower level.

With the advantages of low loss and low heat generation, Laminated Bus Bar for Telecom has been widely used in various high-power power transmission systems. In the field of new energy vehicles, BusBar for Transformer are used for high-voltage connections from battery packs to inverters, maintaining low heat operation at hundreds of kilowatts of power transmission, improving power system efficiency, and extending component lifespan. In energy storage systems, the Laminated Bus Bar for IGBT-based Motor Drive is responsible for battery module convergence and PCS power conversion tasks. Its low resistance and high heat dissipation characteristics can avoid overheating at the convergence point, improving system safety and cycle efficiency. In the field of industrial frequency converters, Laminated Bus Bar for High Current Inverter can effectively suppress skin effect, reduce the operating temperature of power modules, and improve the long-term reliability of equipment operation. In addition, in scenarios such as photovoltaic inverters, rail transit, and high-power power sources, stacked busbars also play a stable, efficient, and low heat transmission role.

Reliable design and manufacturing processes are important guarantees for the Laminated Bus Bar for Mounting Structure of Capacity Bank to achieve low heat generation and high stability operation. High conductivity oxygen free copper is usually used as the conductor in materials, combined with high temperature resistant and high insulation performance dielectric materials to ensure safe conductivity and insulation. The process adopts vacuum bonding technology to eliminate interlayer bubbles and gaps, reduce interface thermal resistance, and avoid the risk of partial discharge and overheating. At the same time, customized design needs to be carried out based on actual current, voltage, space, and heat dissipation conditions, reasonably determining the number of layers, thickness, and external structure of Laminated Busbar Design to ensure current balance, sufficient heat dissipation, and installation adaptability.

The Laminated Bus Bar for Hign Frequency Welding Power IGBT, with its comprehensive advantages of low resistance, low inductance, and high heat dissipation, effectively solves the heating problem in high-power power transmission, significantly improves system efficiency, reliability, and safety, and has become a key component of modern power electronic equipment. With the rapid development of new energy, energy storage, industrial automation and other fields, BusBar for Electric Locomotive is constantly upgrading towards lightweight, integrated, and high power density. In the future, driven by the demand for higher power, higher frequency, and higher reliability, stacked busbars will continue to optimize materials, structures, and manufacturing technologies, providing stronger support for the efficient and safe operation of high-power power transmission systems.
