Battery Bus Bar
Products Description
A battery bus bar is essentially a high-conductivity metallic conductor, typically made of high-purity copper. Through optimized cross-sectional design and surface engineering, it achieves stable current transmission under high current density. Compared to traditional cable connections, copper busbars offer lower contact resistance, stronger mechanical stability, and superior heat dissipation, making them particularly suitable for continuous high current and multi-node parallel structures.
Products are available in the following forms to meet application requirements:
Bare copper busbar (no surface treatment): Suitable for standard environments and internally encapsulated systems, prioritizing conductivity.
Nickel-plated copper busbar: Enhances oxidation and corrosion resistance, suitable for humid or high-reliability applications.
Zinc-plated copper busbar: Balances economy and basic protection performance, used in general industrial applications.
By combining different surface finishes and structural forms, busbars can achieve balanced current distribution and low-loss connections in complex electrical systems.
Material Advantages: Absolute Purity of T2 Grade Pure Copper
Guaranteed Conductivity
Copper content ≥ 99.95%, conductivity meets IACS international standards, minimizing heat conversion during power transmission.
Thermal Stability
Superior materials ensure excellent heat dissipation capabilities of the bending copper busbar under continuous load, preventing localized overheating and system failure.
Plasticity and Toughness
Possesses excellent cold bending performance; the material fibers do not break or develop microcracks during complex 90-degree or multi-level bends.
Manufacturing Process and Advantages: A Concentrated Example of Precision Industry
| Laser Precision Blanking and Cutting | Abandoning traditional sawing processes, we employ high-precision laser cutting or precision punching for blanking. Laser cuts are smooth and burr-free, and the heat-affected zone is controlled at the micron level, avoiding the risk of partial discharge caused by rough cutting. For irregularly shaped chatsworth ground bus bars, laser cutting provides a high degree of design freedom. |
| CNC Bending and 3D Forming | Using a high-precision CNC bending machine and specialized molds, we achieve three-dimensional bending of copper busbars. Our process ensures precise and consistent bending angles, eliminates visible cracks at the bends, and maintains the integrity of the cross-sectional area, avoiding increased local resistance due to thinning during bending. |
| Press-fit Nut/Stud Insertion Technology | For thin copper busbars that cannot be directly tapped, we use a high-tonnage press-fit machine to insert nuts or studs. The press-fit torque meets stringent standards, ensuring high thread precision and strong pull-out resistance. Compared to welded studs, the press-fit process eliminates the risk of weld spatter. It does not damage the integrity of the copper busbar's plating, making it particularly suitable for UPS server rooms with extremely high cleanliness requirements. |
| Fully Automated Rack Plating Production Line | The surface treatment process utilizes a fully automated rack plating line, avoiding surface scratches caused by workpiece collisions during barrel plating. The rack plating process ensures uniform plating in deep holes, grooves, and other hard-to-reach areas of the copper busbar bending, eliminating the risk of "blind spot" corrosion. |
Application Advantages: Deep Focus on Three Core Areas
1. Power Equipment and High/Low Voltage Switchgear
In switchgear and distribution boxes, rigid copper busbars are the standard conductive carriers. Our galvanized copper busbars, with their high cost-effectiveness and excellent grounding performance, are widely used in grounding systems; while nickel-plated copper busbars, due to their superior conductivity and corrosion resistance, are the preferred choice for main busbars. Products comply with IEC and GB standards, ensuring that complete sets of equipment can successfully pass CCC certification.
2. New Energy Photovoltaics and Energy Storage
Photovoltaic power plants are mostly built outdoors in harsh environments. Our photovoltaic-specific nickel-plated copper busbars have undergone rigorous salt spray testing and can resist acid rain and sandstorm corrosion. Their UV-resistant insulating sheath design ensures that they will not age or break down under long-term direct sunlight, guaranteeing stable operation of the photovoltaic power plant throughout its 25-year lifespan.
3. UPS Uninterruptible Power Supply Servers
Data centers have extremely high requirements for power supply reliability. Our UPS-specific copper ground busbars are manufactured with high precision to ensure consistent torque at every bolt connection, eliminating the risk of power outages caused by poor contact. The copper busbar has a high surface flatness, which effectively reduces the skin effect loss under high frequency ripple and ensures a clean power input for the server.
