Copper Foil Multi-Layer Welding Busbar
The Copper Foil Multi-Layer Welding Busbar is constructed by laminating multiple layers of high-purity copper foil and connecting them into a single integrated structure through a solid-phase diffusion welding process. Unlike traditional mechanical riveting or silver soldering, diffusion welding creates a metallurgical bond between each layer of copper foil without solder or impurities, achieving a low-resistance, high-density, and highly reliable conductive connection.
The entire Copper Foil Connector combines the bendability of a flexible conductor with the overall rigidity and long-term stability of the busbar structure, making it an ideal solution for connecting power battery modules, converters, power distribution systems, and other electrical equipment.
Using high-purity T2 oxygen-free copper or C1100 copper foil, the conductivity reaches over 99.9%, ensuring low-loss, high-efficiency current conduction for Copper Foil Flexible Busbar.
01
The multiple layers of copper foil maintain slippage, effectively absorbing equipment vibration and thermal expansion stress, extending system life for Flexible Copper Foil Laminated Connectors.
02
Using a vacuum diffusion welding process to form a metallurgical bond under high-temperature and high-pressure conditions, this eliminates solder interlayers, voids, and oxidation, improving contact reliability and electrical stability.
03
The diffusion-bonded surface is free of oxide layers, resulting in extremely low resistance and long-term stable operation in high-temperature, high-current environments.
04
A variety of sizes, hole positions, terminal structures, and plating options are available to accommodate different equipment layouts and current levels for Laminated Copper Flexible Connectors.
05
The Copper Foil Flexible Storage Energy Battery Busbar body is constructed from high-purity oxygen-free copper (T2 or C1100), precision-rolled to form a copper foil layer with uniform thickness and a smooth surface. This material exhibits excellent electrical and thermal conductivity, maintaining low temperature rise and stable current conduction even under high current density conditions.
Tin, nickel, or silver plating can be selected based on application requirements to enhance oxidation and corrosion resistance. Uniform coating ensures long-term operation in high humidity, salt spray, and complex industrial environments.
Multiple layers of copper foil are precisely laminated to ensure both a stable lateral conductive area and flexible deformation, ensuring excellent performance despite repeated bending and micro-vibration, and resisting breakage or delamination for a Flexible copper laminated busbar.
| The diffusion-bonded terminal structure is flat and solid, with no voids or delamination, ensuring low contact resistance and high mechanical strength. | |
| Multi-dimensional Spatial Flexibility | Enables flexible routing within confined equipment spaces, enabling optimal routing for complex electrical systems. |
| Compared to traditional thick Copper Foil Bus Bars, the copper foil laminated structure significantly reduces weight, maintaining high current carrying capacity while reducing system load. | |
| The terminal can be designed with round holes, elongated holes, special-shaped terminals, or bolt-on welds for easy assembly and maintenance. |
