Busbar device and method for producing a busbar device

A method for producing a busbar device for carrying and distributing electric currents, the busbar device having at least one ferrite core filter and having at least two busbars, wherein the at least two busbars are each one-piece busbars, which are spaced from one another in an electrically insulated manner, wherein the busbars have the same or different electric potentials, so that the busbars can carry an electric current appropriate for a bar cross-sectional area, the method comprising:

• bend forming and re-shaping the one-piece busbars in a first step, and
• guiding the busbars through a passage area of a feed-through opening of the ferrite core filter in a following step, so that a passage cross-sectional area of the busbars in the passage area is at least just the same size as the bar cross-sectional area of the busbars outside the passage area, so that the busbars can carry the same electric current along the run of the busbars;
• wherein the at least two busbars are in each case reshaped by at least 90 degrees along the passage area of the feed-through opening in a v-or u-shaped manner via bend forming.
