1. A branch busbar device for high-voltage and/or medium-voltage arrangements, whereby the branch busbar device comprises a first electric line with a first electric contact area and a second electric line with a second electric contact area, whereby the first electric contact area is connected to the second electric contact area, whereby a first field limiting part is arranged at a first place adjacent to the contact areas, whereby a second field limiting part is arranged at a second place adjacent to the contact areas, and whereby the first field limiting part and the second field limiting part are electrically connected to the first electric line or to the second electric line or to a third electric line of the branch busbar device, wherein the first field limiting part comprises a first slim plate, that the first slim plate comprises a conductive material, and that the first slim plate is connected to one of the electric lines, wherein border parts of the first slim plate are encased by a first insulating coat, wherein the second field limiting part comprises a second slim plate, the second slim plate comprises a second conductive material, and the second slim plate is connected to one of the electric lines, wherein border parts of the second slim plate are encased by a second insulating coat, and wherein the first insulating coat and the second insulating coat enhance the positive effect of the first field limiting part and the second field limiting part for the first electric contact area of the first electric line and the second electric contact area of the second electric line.
