Laminated Copper BusBar: An Efficient Electrical Connection Solution For The New Energy Industry
Jun 18, 2025
Laminated Copper BusBar is a multi-layer composite structure connection bar, widely used in new energy vehicles, power electronics equipment, and communication systems. It is formed by laminating and pressing multiple layers of copper foil with insulating materials to create a unified structure, effectively reducing inductance, voltage drop, and improving heat dissipation. Compared to traditional single-layer copper bars, Laminated BusBars offers significant advantages in high current density and high-frequency applications.
Material Characteristics
The main material of Laminated Copper BusBar is high-purity T2 copper, with a copper content of up to 99.9%, providing excellent electrical conductivity and low electrical resistivity. Additionally, the copper foils are separated by insulating materials such as epoxy resin and polyester film, which not only provide electrical isolation but also enhance the mechanical strength and corrosion resistance of the busbar.
Production Process
The production process of Laminated BusBars includes several key steps:
| Copper Foil Cutting and Lamination | Multiple layers of copper foil are cut and stacked according to the design requirements. |
| Insulation Material Insertion | Insulating materials are inserted between copper foils to ensure electrical isolation. |
| Pressing and Curing | The copper foils and insulating materials are pressed and cured together under high temperature and pressure. |
| Surface Treatment | Surface treatments such as tin plating, nickel plating, or silver plating are applied to improve oxidation resistance and contact performance. |
| Quality Inspection | The finished products are rigorously tested for electrical and mechanical performance to ensure compliance with standards. |
