Angle Copper Busbar

An angle copper busbar is a T2 copper conductor formed into an L-shaped, angle-steel style cross-section rather than a flat bar. One leg sits flat against the panel backplane and bolts down, while the other leg stands forward to receive component connections, so the same part carries current and serves as its own mounting bracket. Because the 90-degree corner is the critical feature, we control the inner corner radius for each material thickness - too large and bolt heads cannot seat flat against the copper, too small and the bend cracks under load. The angle is checked after forming so the L seats squarely against the panel, and leg lengths and thickness follow customer drawings. Produced to GB/T5585.1-2026, the T2 copper reaches Cu >= 99.90% purity with >= 97.3% IACS conductivity.
 

For panel builders, an angle busbar that fits on one piece but drifts on the next is a real assembly problem, because there is nothing to adjust on site. We select the bending die for the specific thickness and hold the inner radius against an in-house reference table, then verify the 90-degree angle on each piece before it leaves the line. Run across a batch, the value is consistency: leg length, corner radius and right angle land within the same tolerance order after order, so your crew bolts the bar down the same way every time. Because we cut bulk only after a pre-production sample you confirm, the cross-section you approved is the cross-section you receive in full production.
