Product Details (Core Functions of Copper Busbars)
Copper busbars deliver three core functions in charging piles:
High-Current Transmission
Connecting grid, rectifier modules, and output cables for efficient and stable power delivery.
Equipotential Bonding & Grounding
Equalizing enclosure and structural potentials while providing safe protection paths.
Absorbing Vibration & Thermal Expansion
Preventing rigid connections from fatigue failure due to temperature changes and external shocks.
Low parasitic inductance effectively suppresses switching overvoltage, protecting power devices; flat profile saves cabinet depth and increases power density; custom L/Z shapes fit compact layouts.
Ultimate flexibility with an extremely small bending radius, absorbing plug/unplug shocks and cabinet vibrations; the braided structure distributes stress to resist high-frequency fatigue; open surface enhances heat dissipation; high tolerance simplifies on-site assembly.
Manufactured from high-purity T2 copper via rolling or extrusion, offering extremely high current-carrying capacity and strong mechanical rigidity. With a fixed form, they are ideal for main-circuit busing and distribution connections, delivering superior cost-effectiveness for standardized mass production.
Frequently Asked Questions (FAQ)
Copper busbars offer superior current-carrying capacity, lower electrical resistance, and compact structural integration compared to traditional round cables. They effectively minimize space inside crowded charging enclosures and facilitate superior thermal dissipation.
Braided copper busbars feature exceptional flexibility and a tight bend radius. They absorb thermal expansion cycles, mechanical vibrations, and shocks during charging cable handling, preventing connection looseness and fatigue failures.
Laminated busbars minimize parasitic inductance, which suppresses peak switching overvoltages and protects sensitive power semiconductor components. Their slim profile also boosts power density in space-constrained cabinets.
Rigid busbars are fabricated from high-purity T2 copper using rolling or extrusion processes, ensuring exceptional electrical conductivity, robust structural rigidity, and dependable long-term continuous operation.
