Laminated Copper New Energy Connecting Busbar
Products Description
Laminated Copper New Energy Connecting Busbars are flexible connectors formed by stacking and pressing multiple layers of high-purity copper foil. They possess excellent conductivity, low impedance characteristics, and high mechanical adaptability. Based on application scenarios, they can be divided into two categories:
Small flexible copper foil busbars: Primarily used for series-parallel connections, voltage balancing, and high-frequency dynamic load transmission within new energy vehicle battery packs.
Large laminated busbars: Suitable for power distribution equipment, industrial high-voltage switchgear, and DC control systems, enabling reliable conduction under high current and high power conditions.
Their main features include:
High conductivity and low contact resistance
Flexible design to adapt to thermal expansion and mechanical vibration
Optimized laminated structure to reduce electromagnetic interference
Customizable number of layers and thickness according to current requirements
Material Advantages: Ensuring Current Carrying Limits at the Crystal Lattice Level
High-Purity T2 Copper Substrate
Multi-Layer Bending Power Electrical Busbar Using extremely high-purity T2 copper foil as the substrate, its oxygen content is strictly controlled, its crystal structure is dense, and its electron scattering rate is extremely low. This ensures excellent conductivity and thermal conductivity from the material source, minimizing Joule heat generated when large currents pass through.
Annealing Process Reshaping Plasticity
Before slitting and laminating, the copper foil undergoes precision annealing to eliminate processing stress and restore its molecular-level ductility and flexibility. This ensures that the final soft connection will not harden or develop microcracks even under repeated bending and torsion.
Multi-Dimensional Surface Protection System
Copper Laminated Flexible Shunts provide surface treatment solutions, including bare copper, tin plating, nickel plating, and silver plating, for various application environments. Tin plating provides excellent corrosion and oxidation resistance, making it suitable for harsh electrical environments. Nickel plating enhances high-temperature resistance, and silver plating reduces contact resistance to the micro-ohm level, making it the preferred choice for terminal connections in high-end new energy battery packs.
Detailed Showcase and Customer Value
Smooth, Burr-Free Contact Surfaces
Precision-polished contact surfaces combined with standardized drilling ensure full contact with terminals during installation, reducing contact resistance and minimizing heat sources.
High Consistency and No Interlayer Misalignment
Strict control over stacking fixtures and welding jigs prevents interlayer slippage or misalignment of multi-layer copper foil during welding.
Weather-Resistant Surface Treatment
The tin plating thickness is rationally configured according to the operating environment and has been verified through salt spray testing, making it suitable for coastal industrial areas or outdoor Multi-Layer Copper Foil Bus Bar for Electricity System applications.
Full Specification Standards and Customized Drawing Compatibility
Supports customized needs based on CAD engineering drawings. A segmented confirmation system is implemented from sample making to mass delivery, avoiding on-site rework issues caused by dimensional discrepancies from the outset.
Main functions: Power transmission, stress reduction, and safety shielding
High-efficiency current carrying
Press Welding Foil Busbar provides maximum current-carrying capacity within a minimal cross-sectional area.
Vibration resistance and fatigue prevention
Absorbs minute vibrations across the entire frequency range during vehicle powertrain operation.
Safety protection
Copper Foil Flexible Connector for Busway Systems provides a reliable electrical insulation barrier for the system through the selection of flame-retardant (UL94 V-0 grade), high-temperature resistant, high-performance insulating outer layers.
