Product Description
The ASTM C11000 T2 Copper Bus Bar is a high-performance, solid electrical conductor designed for demanding power distribution systems. Manufactured from 99.99% pure electrolytic copper, this bus bar delivers exceptional electrical and thermal conductivity, making it the preferred choice for switchgear cabinets, panelboards, and industrial machinery.
With a conductivity rating of 100.98% IACS and low resistivity of 0.01707 Ω·mm²/m, this copper bus bar minimizes energy loss and heat generation. Its red, square or round-edged profile is available in custom lengths up to 6 meters, with thicknesses from 5mm to 100mm and widths from 10mm to 200mm. Each bar undergoes strict quality control to ensure mechanical strength, corrosion resistance, and long-term reliability.

A copper bus bar functions as a low-impedance conductor distributing high currents across multiple circuits. Unlike insulated cables, the rigid bus bar provides a direct, short-length path for current flow between incoming power sources and outgoing feeders.
When installed inside a switchgear cabinet, the bus bar connects the main breaker to branch breakers or disconnects. Due to copper’s high conductivity (second only to silver), voltage drop along the bar is minimal. Its large cross-sectional area and thermal mass allow it to carry hundreds or thousands of amperes without excessive temperature rise.
The 99.99% pure copper composition ensures grain boundaries are free of oxides or impurities, which would otherwise increase resistance and create hot spots. This purity, combined with proper cross-section sizing, guarantees stable operation under continuous or intermittent loads.
Q1: What is the difference between ASTM C11000 and T2 copper?
A: They are equivalent specifications. ASTM C11000 is the U.S. standard for electrolytic tough pitch (ETP) copper, while T2 is the Chinese GB standard. Both require minimum 99.9% copper content, but our product exceeds that at 99.99%.
Q2: Can you cut the bus bar to custom lengths?
A: Yes. We offer custom lengths from 0 to 6 meters. Longer lengths may be available upon request.
Q3: Is this bus bar suitable for outdoor use?
A: While copper has natural corrosion resistance, outdoor applications often require additional plating (tin, nickel, or silver) or anti-corrosion coating. Please contact us for surface treatment options.
Q4: What is the maximum current capacity?
A: Current capacity depends on cross-section, ambient temperature, and allowable temperature rise. For a typical 50×5mm bar, continuous current can exceed 500A. Contact our engineers for exact sizing.
Q5: What edge types are available?
A: Both round edges (for reduced corona discharge and safer handling) and square edges are available.
Q6: How is the product packaged for shipment?
A: Each bus bar is individually protected and packed in sturdy wooden boxes to prevent bending or scratching during transit.
Q7: What is your lead time for a 300 kg order?
A: Standard lead time is 15–25 working days after deposit confirmation.
Q8: Do you provide test certificates?
A: Yes. We provide mill test certificates (MTC) including chemical composition and conductivity results for each batch.
