A bus bar assembly includes a bus bar formed of a first electrically conductive material having a planar contact portion. The bus bar defines a first bore extending through the contact portion. The bus bar assembly further includes a contact insert formed of a second electrically conductive material that has a greater hardness than the first electrically conductive material. The contact insert defines a first surface that is mechanically and electrically connected to the contact portion of the bus bar. The contact insert defines a second surface this is plated with a third electrically conductive material which is different than the second electrically conductive material. The contact insert defines a smooth second bore coaxial with the first bore and extending from the first surface to the second surface.

A busbar for an aircraft with at least two conductive layers and at least three insulating layers. The conductive layers and the insulating layers are stacked together alternatingly and extend in a longitudinal direction. The conductive layers and the insulating layers include different coefficients of thermal expansion. Each of the conductive layers includes spatial structures. Each spatial structure is connected to an adjacent one by an interconnecting segment. Each conductive layer is embedded between two insulating layers, resulting in a deforming of the side walls of the spatial structures under heat, thereby compensating a longitudinal expansion of the conductive layers. Further, an aircraft with a disclosed busbar and a method of producing such busbar is provided.
