Frequently Asked Questions
Q
What is C11000 copper and why is it used for busbars?
C11000 (ETP) copper is electrolytic tough pitch copper with a minimum purity of 99.9%. It offers excellent electrical conductivity (≥100% IACS), outstanding thermal conductivity, and good mechanical workability, making it the preferred material for power distribution busbars in switchgear, transformers, and electrical panels.
Q
Can you produce busbars in custom shapes such as L, U, or Z profiles?
Yes. We specialize in custom-shaped copper busbars including L‑shaped, U‑shaped, Z‑shaped, and fully irregular profiles. All shapes are produced via CNC bending, punching, drilling, milling, and cutting to meet your exact drawing or sample requirements.
Q
What surface treatment options are available for copper busbars?
We offer bare copper, tin plating (0.8–3μm), and nickel plating (1–5μm). Optional insulation coatings include PVC/PE heat shrink tubing and epoxy coating rated UL94V‑0. The appropriate treatment can be selected based on your application environment and electrical requirements.
Q
What is the minimum order quantity (MOQ) and lead time?
The MOQ is 5 pcs for standard custom shapes, and 1 pc for prototypes (negotiable). Lead time is typically 5–7 business days for simple shapes and 7–15 business days for complex profiles, depending on specifications and order volume.
Q
Which international standards do your copper busbars comply with?
Our C11000 copper busbars comply with ASTM B152, ASTM B187, IEC 60439, and RoHS directives. We maintain a strict ISO 9001 quality management system to ensure consistent product quality and traceability for every order.
Q
How are the busbars packaged and shipped internationally?
Each order is carefully packaged with moisture‑proof film, anti‑scratch paper, export-grade carton, and wooden pallets to prevent damage during transit. We ship worldwide by sea, air, or express courier (DHL / FedEx / UPS), and can assist with customs documentation upon request.
