Advantages
Product Display
Core Application
Rigid copper busbar is used for electrical conduction in power, automotive and mechanical equipment that requires standard and special-shaped connections. It features high strength, shock resistance and anti-deformation. It is widely applied in hard connection of electrical equipment such as distribution cabinets and transformers.
Operating Conditions
- Temperature range: -40℃ to +120℃ (dip-coating/epoxy raises upper limit).
- Relative humidity: ≤95% non-condensing.
- Ideal applications: Hard connections in distribution cabinets, transformers, EV battery modules, high-power charging piles, industrial VFDs.
- Flammability rating: Meets UL94 V-0.
Maintenance & Service Life
- Designed service life ≥20 years under rated current and environmental conditions.
- Recommended torque and insulation check every 6 months.
- For dip-coated or PI film insulated busbars, clean with dry lint-free cloth; avoid organic solvents.

Frequently Asked Questions
What copper material is used for the rigid copper busbars?
Our rigid copper busbars are manufactured from premium C11000 and C10100 grade copper with electrical conductivity ≥98% IACS, effectively minimizing resistive power loss and heat build-up.
What insulation coating options are available?
We offer multiple insulation solutions including PVC dip coating, epoxy powder spray coating, PI film wrapping, heat shrink tubing, and glass fiber sleeving to meet specific voltage, temperature, and space requirements.
What is the operating temperature range and flame resistance rating?
The busbars operate smoothly between -40℃ to +120℃ (with dip-coating/epoxy further increasing temperature limits), operate under relative humidity ≤95%, and meet the UL94 V-0 flammability standard.
Can rigid copper busbars be customized to specific engineering drawings?
Yes, we provide full customization capabilities including precision laser cutting, stamping, CNC 3D bending, deburring, and specialized surface treatments (tin, silver, or nickel plating) according to customer blueprints.
What is the expected service life and maintenance routine?
The designed lifespan is ≥20 years under normal operating conditions. Regular maintenance requires torque verification and insulation resistance inspections every 6 months, using dry lint-free cloths for surface cleaning without organic solvents.
What applications are best suited for rigid copper busbars?
They are extensively applied for solid/hard electrical connections in power distribution cabinets, switchgear, power transformers, electric vehicle (EV) battery packs, high-power DC fast charging stations, and industrial variable frequency drives (VFDs).
