Frequently Asked Questions

Q What conductor material is used in your insulated flexible braided copper busbars?

Our busbars use T2 electrolytic copper with a purity of Cu≥99.95%, ensuring excellent electrical conductivity, low resistance, and long-term reliability in demanding applications.

Q Can the insulated flexible copper busbar be customized to specific dimensions?

Yes. We offer full size customization including cross-section (24mm²–1200mm²), length (100mm–6000mm), and installation hole positions/spacing — all processed according to your provided drawings or specifications.

Q What insulation materials are available for the flexible copper busbar?

We offer multiple insulation options including TPE/LSHFFR (low smoke zero halogen flame retardant), PE heat shrink tubing, and PVC. Special grades such as oil-resistant or heat-resistant variants are also available upon request.

Q What surface treatment options are available?

We provide four surface treatment options: bare copper, tin plating, silver plating, and nickel plating. Each option offers different levels of oxidation resistance and contact performance to suit various application environments.

Q What is the typical lead time for orders?

For sample orders, the lead time is typically 3–7 working days. For bulk production orders, the lead time is 8–12 working days, depending on the structural complexity and order volume.

Q What industries and applications are these flexible copper busbars suitable for?
