Precision Copper Busbar for Rail Transit - China Suppliers & Factory Custom Solutions

Select T2/T3 copper, C11000 electrolytic copper. The copper purity is ≥ 99.95%, and the conductivity is ≥ 98% IACS. The low-resistance characteristic can effectively reduce energy loss during current transmission, improve the operational efficiency of the power system, and is suitable for high-current and high-precision power supply scenarios.

Through fully automated processes such as CNC cutting, precise bending, and precise drilling, the dimensional tolerance is strictly controlled within ±0.05mm, and the bending angle error is ≤±0.5°. The surface is polished and deburred, with a roughness Ra of ≤0.8μm, without sharp edges or corners, which avoids scratching the insulation components during installation and ensures the safety and fit of the assembly.

It has excellent anti-oxidation and corrosion resistance properties. Bare copper products can be used stably in a dry environment for a long time; products with surface treatments such as tin plating and silver plating can withstand complex environments like humidity and dust. The working temperature range is -40℃ to +120℃. Special customized models can be adapted to high-temperature scenarios up to +200℃. The service life is long.

Covering both standard and non-standard specifications, with cross-sectional dimensions (width × thickness) ranging from 10×2mm to 300×25mm, the maximum length can reach up to 12 meters. It can be cut to size as needed. Support various surface treatments such as tin plating, silver plating, passivation, and insulation coating, which are suitable for different corrosive environments and assembly requirements.
