Abstract
Abstract A laminated bus bar comprises a pair of elongated flat conductors separated by a layer of insulating material which is provided with longitudinally spaced cut-outs. Capacitors which are comprised of a flat wafer of solid dielectric material are positioned in each of the cut-outs in the layer of insulating material and the capacitor plates are electrically and mechanically connected to the conductors.
