Custom Copper Busbars

Material & Manufacturing
Engineered for Superior Power Distribution

At JUMAI Tech, we manufacture custom copper busbars utilizing high-purity T2/C11000 copper (99.9% pure). Our busbars are critical components for efficient power transmission, offering exceptionally low electrical resistance and excellent thermal management properties.

Whether you need robust rigid connections for heavy industrial machinery or highly flexible braided solutions for the vibration-heavy environments of New Energy Vehicles (NEVs), we have the complete in-house capabilities to punch, bend, plate, and insulate to your exact CAD specifications.

Types of Copper Busbars We Manufacture

We offer three primary categories of busbars, fully customizable in shape, size, and finish to suit your specific spatial, electrical, and mechanical requirements.

Standard Power

Hard / Rigid Busbars

Solid copper bars precision cut, punched, and CNC bent. Ideal for static applications requiring massive current carrying capacity and structural rigidity where vibration is not a primary concern.

Low voltage drop
High mechanical strength
Complex 3D CNC bending
High Vibration

Soft / Braided Busbars

Woven from fine copper wires (bare or tinned) with solid cold-pressed terminals. Specifically designed to absorb extreme vibrations, accommodate thermal expansion, and compensate for dynamic misalignments.

Maximum flexibility
Shock & vibration absorption
Custom terminal pressing
Tight Spaces

Laminated Flexible Busbars

Constructed from multiple layers of thin copper foils, firmly press-welded (diffusion welding) at the mounting areas. Offers the exceptional conductivity of solid bars combined with the ability to bend and twist in extremely tight spaces.

Space-saving routing
Excellent heat dissipation
Reduced skin effect
Industries We Serve

Powering the Industries That Move the World

Our precision-engineered copper busbars deliver safe, efficient, and reliable power distribution across demanding industrial applications. From electrification and renewable energy to critical infrastructure, we build solutions designed for performance, durability, and exact application requirements.

NEVs & Batteries

High-performance busbar solutions for battery packs and electric vehicle systems, engineered for reliable current flow, compact integration, and high-vibration environments.

Renewable Energy

Precision copper busbars designed for solar inverters, energy storage systems, and wind power equipment, helping manage high currents efficiently and reliably.

Power Distribution

Custom busbars for switchgear, transformers, control panels, and electrical distribution systems, providing dependable connections and efficient power transfer.

Data Centers

Reliable power distribution solutions for data center infrastructure, supporting uninterrupted power delivery across server racks, UPS systems, and critical electrical equipment.

Customization
Surface Finishes & Insulation Capabilities

We deliver more than raw copper. JUMAI Tech provides fully finished, ready-to-assemble components equipped with required surface protections against oxidation and high-grade electrical insulation for safety.

Plating & Coatings

Prevent oxidation and reduce contact resistance. We offer Tin Plating (Sn) for standard anti-corrosion, Nickel Plating (Ni) for harsh environments, and Silver Plating (Ag) for ultimate conductivity at contact points. Bare copper is also available.

Electrical Insulation

Safety is paramount. Choose from Heat Shrink Tubing, custom PVC Dipping for complex shapes, or high-performance Epoxy Powder Coating. All insulations can be formulated to meet UL94 V-0 flame retardant standards.

Precision Machining

Our CNC equipment ensures tight tolerances. Capabilities include multi-axis CNC bending, precision punching, hole tapping, cold pressing for braided terminals, and advanced diffusion welding for laminates.

How We Work

From Drawing to Delivery

A streamlined, transparent process ensuring your custom components meet exact specifications on time.

1. Drawing Evaluation

Send your 2D/3D CAD files. Our engineers review for manufacturability (DFM) and provide a quote.

2. Rapid Prototyping

We produce physical samples for your team to test fit, form, and electrical function before mass production.

3. Mass Production

Upon approval, we initiate CNC machining, pressing, plating, and insulation processes.

4. QC & Global Shipping

100% inspection for dimensional accuracy and insulation integrity prior to secure global dispatch.
