Product Introduction
Flexible Laminated Copper Bus Bars (FLCBs) are essential conductive components in modern power systems and new energy equipment. They are made from multiple layers of high-quality electrolytic copper foil or sheet through welding, riveting, or diffusion bonding. The surface can be tinned, silvered, or nickel-plated as desired. Known for their flexibility, high conductivity, low impedance, and excellent fatigue resistance, FLCBs are widely used in new energy battery modules, energy storage systems, rail transit, variable-frequency power supplies, charging stations, and industrial automation equipment.
Compared to traditional solid copper busbars, FLCBs effectively absorb vibration and thermal expansion in electrical equipment, ensuring stable electrical performance and mechanical strength even under high current transmission and dynamic operating conditions. They are an ideal solution for high-performance electrical connections and safe electrical conduction.

High Conductivity and Low Impedance Design
Using high-purity T2 electrolytic copper (Cu ≥ 99.9%), it maintains extremely low resistance and temperature rise during high current transmission, significantly reducing energy loss.
01
A multi-layer laminated structure combines flexibility and stability
The multi-layer copper foil structure maintains a flexible connection despite bending, vibration, and temperature fluctuations, effectively reducing mechanical stress and fatigue damage at the connection points.
02
Highly Reliable Welding and Anti-Oxidation Surface
Using precision diffusion welding or friction welding processes to achieve molecular-level bonding between the multiple copper sheets. The surface can be plated with tin, silver, or nickel to enhance corrosion resistance and conductive stability.
03
Precision Customization and Modular Design
Customizable shapes, thicknesses, hole pitches, and terminal types can be tailored according to customer drawings, ensuring compatibility with various installation requirements, including Copper Foil Bus Bars, terminal blocks, and bolt-on connections.
04
Excellent Heat Dissipation and Electromagnetic Shielding Performance
The multi-layer stacked structure quickly disperses heat during high-current operation, preventing localized overheating and providing excellent electromagnetic interference (EMI) shielding.
05
Material Advantages
High-Purity T2 Electrolytic Copper
Tinned Foil Connector for Electrical Battery selected refined and annealed T2 copper strip boasts excellent electrical conductivity (IACS ≥ 99%), ensuring efficient power transmission and reducing energy consumption and heat loss.
High-Strength Insulation
Copper Foil Connector imported polyester film, polyimide (PI), or PET insulation films are used between layers to withstand high temperatures (over 155°C), arcing, and humidity, ensuring long-term, safe operation.
Environmentally Friendly Coatings and Corrosion Protection
The tin plating prevents oxidation and improves weldability; the silver plating enhances contact conductivity; and the nickel plating is suitable for use in harsh industrial environments. All materials are RoHS and REACH compliant.
High-Reliability Terminals
Terminals can be constructed with copper, aluminum, bolt holes, or silver-embedded contacts to accommodate diverse electrical interface requirements while ensuring consistent mechanical strength and conductivity.
