Frequently Asked Questions (FAQ)
Q
What is the copper purity of your electrolytic copper bus bar?
Our high-purity electrolytic copper bus bars are made from T2 / C11000 / TU2 grade copper with a copper content of ≥99.95%, and premium grades reaching up to 99.99%. This ensures extremely low resistivity (≤0.01724 Ω·mm²/m) and conductivity ≥100% IACS for maximum electrical efficiency.
Q
What surface treatment options are available for the copper bus bars?
We offer a full range of surface treatments to suit different application environments: bare copper, tin-plated, silver-plated, nickel-plated, epoxy coated, and PVC heat shrink insulation. Each option provides different levels of corrosion resistance, conductivity, and environmental protection.
Q
Can the copper bus bars be customized in size and shape?
Yes. We support full customization including thickness (2–30mm), width (10–250mm), and length (standard 1m/2m/3m/6m or custom lengths). We also offer secondary processing services such as cutting, punching, bending, drilling, milling, and tapping to meet your specific project requirements.
Q
What international standards do your copper bus bars comply with?
Our copper bus bars comply with multiple international and domestic standards, including GB/T 5585.1 (China), IEC 60228 (international), ASTM B187 (USA), and RoHS environmental compliance. This ensures the products meet the requirements of global markets and major certification bodies.
Q
What is the working temperature range of the copper bus bar?
The copper bus bars are designed to operate reliably across a wide temperature range from -40℃ to +120℃, making them suitable for both extreme cold environments and high-load industrial applications such as substations, data centers, and EV charging infrastructure.
Q
How are the copper bus bars packaged for shipping?
Our copper bus bars are carefully packaged to prevent damage during transit. Packaging is tailored to the product dimensions and destination requirements, ensuring safe delivery whether shipped domestically or internationally. Please refer to the packaging and shipment images above for more details.
