Frequently Asked Questions
Q
What is C11000 copper and why is it used for busbars?
C11000 (ETP — Electrolytic Tough Pitch) copper offers a minimum purity of 99.9%, delivering electrical conductivity of ≥100% IACS and extremely low resistivity (≤0.0177 Ω·mm²/m). These properties make it the industry standard for busbars used in power distribution, switchgear, and electrical panels where maximum current efficiency is critical.
Q
Can you produce busbars according to my custom drawings or samples?
Yes. We fully support OEM/ODM orders. You can provide 2D/3D drawings, CAD files, or physical samples. Our engineering team will review the design and confirm feasibility before production. All custom shapes — including L, U, Z, and irregular profiles — are available with CNC machining accuracy of ±0.05 mm.
Q
What surface treatment options are available for copper busbars?
We offer several surface treatment options: bare copper (no coating), tin plating (0.8–3μm) for improved solderability and corrosion resistance, and nickel plating (1–5μm) for high-temperature and harsh-environment applications. Optional insulation with PVC/PE heat shrink tubing or epoxy coating (UL94V‑0 rated) is also available.
Q
What is the minimum order quantity (MOQ) and lead time?
The MOQ is 5 pieces for standard custom shapes. For prototype or sample orders, we accept as low as 1 piece (negotiable). Lead time is typically 5–7 business days for simple shapes and 7–15 business days for complex or multi-step profiles, depending on order volume and specifications.
Q
Which international standards do your copper busbars comply with?
Our C11000 copper busbars are manufactured in compliance with ASTM B152, ASTM B187, and IEC 60439 standards. All products are RoHS compliant, ensuring they meet environmental and safety requirements for global markets including Europe, North America, and Southeast Asia.
Q
How are the busbars packaged and shipped internationally?
Each order is carefully packed with moisture-proof film, anti-scratch protective paper, export-grade cartons, and wooden pallets to prevent damage in transit. We ship worldwide via sea freight, air freight, or express courier services (DHL, FedEx, UPS). Our team will recommend the most cost-effective shipping method based on your order size and destination.
