With a high-strength rigid structure designed to withstand shock and deformation, our busbars are fully customizable according to your specifications. Partner with our factory to enhance your projects with top-quality aluminum busbars today.

Product Details

Advantages

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.

Frequently Asked Questions (FAQ)

What are the main advantages of rigid aluminum busbars over copper busbars?

Rigid aluminum busbars provide high electrical conductivity (≥59% IACS) with approximately 70% less weight compared to copper, significantly reducing overall equipment load while maintaining structural rigidity and cost efficiency.

What insulation types are available for rigid aluminum busbars?

Multiple insulation options are available, including PVC dip coating, epoxy spray coating, PI film wrapping, heat shrink tubing, and glass fiber tubing, supporting dielectric voltages from 600V up to 3000V.

What is the standard operating temperature range?

Standard operating temperatures range from -40℃ to +120℃, which can be further extended using specialized dip-coating or epoxy insulation configurations.

Can busbars be custom-designed based on specific drawings?

Yes, full customization is supported via precision laser/die cutting, CNC/3D bending, and specialized plating (passivation, tinning, nickel) to match your custom electrical drawings.

What is the expected service life and maintenance routine?

The expected service life is ≥20 years under rated conditions. It is recommended to perform torque checks and insulation integrity inspections every 6 months.

How is galvanic corrosion prevented on aluminum busbar connections?

Surface treatments such as tinning, nickel plating, or the application of anti-oxidation paste on contact surfaces are used to effectively eliminate galvanic corrosion.
