Product Introduction
Cu Busbar
This product has a high current-carrying capacity, and the current density per unit cross-sectional area can reach 2-4A/mm². Low impedance design reduces line loss and temperature rise. Modular structure supports flexible configuration and expansion. Surface anti-oxidation treatment to maintain stable contact resistance for a long time. Comply with RoHS and REACH environmental standards and meet international power equipment safety regulations.
Material advantages
The selection logic of high-purity oxygen-free copper and tough copper
Copper materials with different oxygen contents and grain size levels are recommended based on the usage scenario (whether there are frequent thermal cycles, whether there is a vibration environment).
Grain refinement process
By controlling rolling and annealing parameters, a uniformly refined equiaxed grain structure is obtained, which significantly improves the fatigue resistance after bending for Electrical Copper BusBar.
Impurity element control
Focus on limiting impurities such as phosphorus, sulfur, and lead that affect conductivity and thermal stability to ensure that long-term flow does not cause local overheating for Power Bar BusBar.
manufacturing technology and processes
Excellent performance comes from rigorous manufacturing. Our production process represents the top level of the copper processing industry, achieving closed-loop quality control from raw materials to finished products.
Source control
Only high-quality cathode copper is used to ensure that the impurity content is controlled within an extremely low range for the Copper Busbar Manufacturer.
Continuous extrusion molding
The introduction of internationally advanced continuous extrusion technology. Compared with traditional continuous casting and rolling, this process can make the metal's streamline distribution more reasonable.
Precision stretching and straightening
Through multi-pass precision stretching, the dimensional tolerance is controlled at the micron level to ensure the smoothness and straightness of the busbar surface, laying a perfect foundation for the subsequent tin plating.
Full inspection system
Each batch of products must undergo ultrasonic flaw detection, conductivity testing and mechanical performance random inspection to ensure zero defects in the factory High Current Connectors.
