Rigid Aluminum Busbars

High conductivity & lightweight: High-conductivity aluminum alloy (≥59% IACS) minimizes resistive loss; density is only 30% of copper, greatly reducing equipment weight.

High strength & deformation resistance: Manufactured from high-strength aluminum alloy, the rigid structure provides excellent shock resistance and anti-deformation, ideal for vibration-prone or high-load-fluctuation environments.

Multiple insulation options: PVC dip coating, epoxy spray coating, PI film wrapping, heat shrink tubing, glass fiber tube. Available with different voltage ratings (up to 3000V), temperature ranges (-40℃ to +120℃, extendable with special insulation), and thicknesses.

Precision manufacturing: Supports laser/die cutting, CNC/3D bending, passivation/tinning/nickel plating surface treatment to ensure accurate dimensions and low contact resistance.

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

Temperature range: -40℃ to +120℃ (extendable with dip-coating/epoxy insulation). Relative humidity ≤95% non-condensing.

Flammability rating meets UL94 V-0. Insulation dielectric strength available from 600V, 1500V to 3000V depending on selection. Contact surface tinning or anti-oxidation treatment is recommended to prevent galvanic corrosion.

Designed service life ≥20 years under rated current and environmental conditions. Recommended torque and insulation integrity check every 6 months.

For dip-coated or PI film insulated connectors, clean with dry lint-free cloth; avoid organic solvents.

If the contact surface is uncoated, regular cleaning and application of anti-oxidation paste is advised.
