Electrolytic Copper Busbar
Products Description
Electrolytic copper busbars are essentially highly conductive, high-current-carrying-capacity metal busbars used in electrical systems to achieve low-loss, high-current, and low-temperature-rise energy transmission.
Their core features include:
High conductivity ≥97% IACS, resulting in high current transmission efficiency.
Strong structural stability, adaptable to complex spaces and multi-point connection scenarios.
Can be combined with insulating materials (PVC, PET, ETFE, epoxy powder, etc.) to enhance system safety.
isolated ground bus bars not only perform power transmission but also serve as a crucial supporting structure for the overall electrical performance, heat dissipation, and service life of equipment.
Structural Design: Balancing Efficiency and Safety
Modular Custom Design
Supports various cross-sectional shapes such as rectangular, slotted, and irregular shapes, with widths ranging from 10mm to 200mm, thicknesses from 2mm to 50mm, and lengths customizable to customer needs (up to 12m per unit length). No splicing required, adaptable to different power distribution spaces and current carrying capacity requirements.
Anti-Oxidation Sealing Structure
busbar connectors connections utilise a combination of silver/tin plating and sealing gaskets to reduce air contact, lower the risk of oxidation, and improve the fit of conductive contact surfaces, preventing overheating due to excessive contact resistance.
Optimised Heat Dissipation Design
Optimises the battery bus bar cross-sectional aspect ratio through finite element analysis, adding heat dissipation grooves or ventilation holes (for high-power scenarios), increasing the heat dissipation area by 30% and enabling more precise temperature rise control.
Material Advantages and Innovations
1. 99.99% High-Purity Electrolytic Copper
Compared to ordinary copper (99.9%), the impurity content is reduced by 90%, significantly improving conductivity and long-term reliability. High-purity copper forms a dense oxide layer in a sulfur-containing environment, effectively preventing corrosion.
2. Oxygen-Free Copper Substrate Technology
The oxygen-free copper treatment process ensures that the copper material is free of pores and impurities, fundamentally solving the stress concentration problem caused by internal defects in traditional copper materials.
3. Environmentally Friendly Surface Treatment
The surface undergoes an environmentally friendly passivation treatment, forming a nanoscale protective film that not only improves corrosion resistance but also meets the most stringent global environmental regulations.
Core Value Created for Customers
System Energy Efficiency Value
Extremely low resistance and optimised high-frequency characteristics directly reduce losses during power transmission. Over long-term operation, the savings in electricity costs can far exceed the initial purchase cost of the copper battery bus bar itself, resulting in a significant return on investment.
01
Power Density and Space Value
By allowing for higher safe current carrying capacity and superior heat dissipation, customers can accommodate higher-power electrical equipment within the same space or design existing equipment more compactly, directly enhancing bending copper busbars competitiveness.
02
Long-Term Reliability and Safety Value
Excellent creep resistance and corrosion resistance ensure the stability of power connection points throughout the equipment's lifespan, significantly reducing the risk of downtime or fires caused by overheating at connection points, and improving the overall system's MTBF (Mean Time Between Failures).
03
Simplified Integration and Optimised Total Cost
Providing pre-assembled, pre-tested busbar electrical assemblies reduces wiring workload and error rates during on-site installation, shortens system integration time, and lowers total installation costs.
