L Shaped Copper Busbar

The corner radius affects bolt installation directly. A large radius creates a curved surface at the corner. Bolt heads may not sit flat against the material. This reduces clamping force. A small radius concentrates stress at the bend point. The material may crack under load. Our workers calculate the optimal radius for each thickness. They have a reference table based on years of experience. The bending die gets selected specifically for your thickness. We also check the angle accuracy after bending. A perfect 90 degrees ensures proper fit against the panel surface. Even one degree off causes alignment problems. Our quality checks catch these issues before shipping.

L shaped copper busbar follows your custom drawings for leg lengths and thickness. The material is T2 copper. Production follows GB/T5585.1-2026. Copper purity reaches Cu≥99.90%. Total impurities stay below 0.10%. Conductivity is ≥97.3% IACS. Resistivity at 20°C stays ≤0.0177 Ω·mm²/m. Density is 8.9 g/cm³. Tensile strength ranges from 220 to 260 MPa. Yield strength exceeds 170 MPa. Hardness is 65 to 90 HV. Elongation is 17% or higher.

Panel builders appreciate the L shape for one simple reason. It speeds up assembly. The pre-formed busbar drops into place quickly. No need to bend material on site. No need to create custom mounting brackets. The busbar itself serves as the bracket. This reduces labor time and material costs. The design also improves reliability. Fewer parts mean fewer potential failure points. Our customers report faster panel assembly times with our L-shaped busbars. The product has become a standard component in their designs.

We start production after receiving your drawings. The design review includes a bend feasibility check. We deliver custom orders within one to two weeks. The minimum order is 1000 kilograms. Mixed specifications are allowed in one order. We accept USD, EUR, and CNY.
