Non-Insulated Rigid Copper Busbar

Ultra-high conductivity: Made of C11000/C10100 copper with conductivity ≥98% IACS, minimizing resistive loss and heat generation.

High strength & deformation resistance:  Rigid structure provides shock resistance and anti-deformation, ideal for vibration-prone or high-load-fluctuation environments.

Precision manufacturing: Supports laser/die cutting, dry polishing/brush deburring, CNC/3D bending, passivation/plating surface treatment to ensure accurate dimensions.

Multiple insulation options: PVC dip coating, epoxy spray coating, PI film wrapping, heat shrink tubing, glass fiber tube – meeting different voltage, temperature, and thickness requirements.

Fully customizable:  Standard or special-shaped connections available per drawing, adaptable to distribution cabinets, transformers, EV battery modules, etc.

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.

Temperature range: -40℃ to +120℃ (dip-coating/epoxy raises upper limit).

Relative humidity ≤95% non-condensing.

Ideal for hard connections in distribution cabinets, transformers, EV battery modules, high-power charging piles, industrial VFDs.

Flammability rating meets UL94 V-0.

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.
