Laminated Busbars by Varnek Busbar Co., Ltd.
A laminated flexible busbar is a stack of thin copper foils, welded at both ends and insulated with PVC dip coating or epoxy powder, that carries high current between cells, modules, inverters and contactors. The lamination lets it absorb vibration and assembly tolerance where a rigid busbar would crack.
