Copper Busbar
Flexible busbars, made from thin layers of copper foil or strips and covered with a heat shrink insulation layer, offer excellent conductivity and heat dissipation. Compared to rigid copper busbars, they are lighter and allow for more flexible and adaptable installation. Flexible copper busbars are widely used in EV battery packs, distribution cabinets, energy batteries, solar panels, etc.

Flexible bus bars are composed of multiple layers of copper foils, varying in width and number of layers. The thickness of these copper foils ranges from 0.1mm to 1mm. Thanks to their excellent conductivity, flexibility, ease of installation, and space-saving design, flexible busbars are widely used in EV battery packs, new energy power distribution systems, UPS systems, charging piles, and more.

RHI bends, punches, welds, rivets, and dips in-house, and uses automatic robots to raise capacity. A project engineering team helps customers hold cost and keep the connection stable.
Flexible insulated busbars feature laminated electrolytic copper conductors, tin or nickel plated surfaces, and EVA heat shrink insulation. With 97 percent IACS or higher conductivity and a temperature resistance range from -50 to 125 degrees Celsius, these copper busbars provide reliable high current transmission from 125A to 1600A for EV batteries, ESS, and power distribution systems.
Flexible busbars, made from thin copper or aluminum foil layers, offer excellent conductivity and flexibility. Their insulation improves heat dissipation, reduces vibration, and saves space. Widely used in EV battery packs, energy systems, UPS, and charging stations, they provide reliable performance in compact environments.
Flexible busbars are made from copper foil with thicknesses ranging from 0.1 to 1mm. Produced through welding, stamping, plating (tin or nickel), forming, and insulation (PVC dipping or PE heat shrink tubing), they offer excellent conductivity, flexibility, easy installation, and space-saving design. These features make them ideal for EV battery packs, new energy power distribution, UPS systems, and charging stations.
Rigid copper busbars excel in both mechanical strength and electrical conductivity, making battery bus bars ideal for applications demanding superior performance in both areas. And the PVC insulation offers excellent wear and weather resistance, making these insulated busbars perfect for demanding environments that need robust, stable power transmission and distribution.
Insulated busbars are widely used in EV applications. Battery busbars feature PA12 insulation with a 5000V AC withstand voltage rating. These copper busbars can be manufactured up to 3 meters in length, enabling high-precision 3D bending for complex routing requirements.
