Direct Factory Production with Full Control
Our pure copper busbar comes from our own production floor. We are not traders or middlemen. Our workshop covers 1200 square meters. We have extrusion units, straightening lines, and overhead cranes. The air compressor system powers all equipment. We operate and maintain these machines ourselves. This means we do not outsource any processing step. Everything happens under one roof. This gives us complete control over quality and delivery. Our team knows the equipment inside out. They can spot potential issues before they affect production. This hands-on capability gives us an edge in flexibility and reliability.
Size Coverage and Material Properties
We stock a broad range of sizes. Thickness from 2.7mm to 12mm. Width from 15mm to 125mm. Stocked sizes include 12×120, 12×100, 10×125, 8×80, 6×60, 5×40, 4×30, and 3×25. The "L" prefix shows the busbar has an L-shaped bend. Standard fixed length is 6000mm. We also cut to custom lengths. Our material meets GB/T5585.1-2026. Copper purity is Cu≥99.90%. Impurities stay within 0.10%. Conductivity reaches ≥97.3% IACS. Resistivity at 20°C does not exceed 0.0177 Ω·mm²/m. Density is 8.9 g/cm³. Tensile strength falls between 220 and 260 MPa. Yield strength stays above 170 MPa. Hardness is 65 to 90 HV. Elongation measures 17% or higher.
CNC Programs Ensure Batch Consistency
We use CNC equipment to maintain processing accuracy. Once we set the parameters, every piece in the batch matches. This method gives better results than manual operations. Before shipping, we inspect the surface condition. We do not re-measure every single piece. But our records show consistent performance across batches. We also welcome third-party inspectors. They can visit our factory and verify our work. Our raw material warehouse stays full. This allows immediate production after order confirmation. Returning customers get priority scheduling. This helps maintain steady supply for your projects.
Main Applications in Power Distribution Equipment
Pure copper busbar serves as the backbone of power distribution. High and low voltage cabinets use it extensively. Switchgear and busway systems rely on it too. Energy storage equipment and power engineering projects depend on its performance. Many electromechanical devices use it for conductive paths. We have supplied domestic assembly plants for many years. Now we serve international customers through our export channel. We check your drawings carefully before production. During manufacturing, we can send progress photos. This keeps you informed at every stage.
Pure copper busbar offers a proven solution for reliable power transmission. The material composition and processing methods ensure long service life. Our manufacturing approach gives you consistent quality across shipments.
