Busbar - hard copper busbar

Advantages: 

High and low voltage power distribution: main busbars of switchgear/distribution cabinets, transformer and switch connections, substation equipment room connections

New energy: DC busbars of energy storage PCS, series connection of battery pack modules/main positive and negative outputs, high-current connections inside charging piles

Industrial equipment: electrodes of electrolysis/electroplating equipment, power connections of welding machines, control centers for large motors

Rail transit: traction converters for locomotives/metro stations, auxiliary power system busbars

· High-purity T2 / C11000 electrolytic copper (Cu ≥ 99.9%) for low electrical resistance and high ampacity.

· Bare, tinned, nickel- or silver-plated surfaces to match corrosion and contact requirements.

· CNC bending, punching, drilling and deburring to your exact drawing and tolerance.

· Optional PET/NOMEX or heat-shrink insulation for creepage and dielectric protection.

· Custom lengths, widths, thicknesses and hole patterns for OEM / ODM projects.

Product Description

Our rigid copper busbar is manufactured from high-purity T2 / C11000 (ETP) electrolytic copper, with Cu purity of 99.9% or above to keep resistance low and current-carrying capacity high. Each solid copper busbar is cut, deburred, bent, punched and drilled by CNC equipment to your drawing, so connection points, hole patterns and angles are consistent from prototype to batch production. Standard surface options include bare copper, tin plating, nickel plating and silver plating, depending on the corrosion environment and contact resistance your application requires. Insulation is available in PET/NOMEX laminate, heat-shrink tubing or powder coating when creepage distance and dielectric protection matter.

The rigid copper bus bar is a core conductor in battery energy storage systems (BESS), EV battery packs, switchgear and control cabinets, busway systems, power distribution panels and renewable energy equipment. Whatever the current rating and layout, we customize thickness, width, length and mounting holes to suit your assembly. Dimensional accuracy follows your tolerance notes (e.g., GB/T 1804-C) so panels and cabinets assemble without rework. As an OEM / ODM copper busbar supplier, we support your design from material selection, plating and insulation to finishing and packaging.

Applications

Rigid copper busbars are widely used in battery energy storage systems (BESS), EV battery packs and charging infrastructure, switchgear and control cabinets, busway systems, power distribution panels and renewable energy equipment. Because the conductor path, current rating and mounting layout differ from project to project, we make each copper busbar to your drawing. Tell us the current rating, operating environment and connection method, and we will recommend the right material, plating and insulation.

 Customization

OEM / ODM rigid copper busbar manufacturing is our core service. Send your drawing (DXF/PDF) or a sample, and we handle material selection, plating, insulation, CNC bending, punching and finishing in-house. Prototype, small-batch and mass production are all supported, with strict dimensional and surface checks before shipping. Contact us to confirm your MOQ, lead time and certification requirements.

Quality control system

Every production step is inspected from raw material forming, welding, surface finishing to pre-assembly testing, with all dimensional, appearance, electrical and corrosion indicators strictly aligned with international technical standards, delivering stable, durable and high-standard custom metal & busbar solutions.
