Insulated Copper-Nickel Busbar with Stable Conductivity for Energy Storage Systems
This precision copper nickel busbar adopts a composite structure of 0.3mm high-purity copper substrate plus 0.15mm uniform nickel plating, strictly manufactured per GB/T standards. Engineered for universal power distribution and battery spot welding scenarios, it integrates copper’s superior electrical conductivity and nickel’s anti-rust, high-temperature resistant traits. The composite material delivers ultra-low contact resistance, extends battery discharge duration and reinforces spot welding firmness. With stable physical performance and excellent weldability, this busbar adapts to high-humidity Southeast Asia, dusty Middle East, temperate Europe and diverse climate zones across Americas. All items pass ISO9001:2015, RoHS and SGS tests, supporting full dimensional customization for diversified electrical assembly demands.
