Tin Plated Copper Flexible Busbar

Tin Plated Copper Flexible Busbar (also known as Flexible Laminated Copper Busbar, Copper Foil Flexible Connector) is a high-performance, flexible power transmission component. It is fabricated by stacking multiple layers of high-purity thin copper foils, bonded through diffusion welding or brazing, with the entire surface or terminals coated with a protective tin layer. It excellently solves challenges of vibration absorption, thermal expansion compensation, and precise alignment in complex electrical installations.

The busbar can be totally customized according to customer drawing (length, width, thickness, hole number & diameter)
