Abstract: An apparatus for establishing a multi-phase electrical connection including at least one connecting element per phase, wherein each connecting element comprises two busbars and a number (N) of substantially identical, flexible conductors arranged in parallel with one another in a plane, said conductors electrically conductively connecting the two busbars. Further, a spacing (a) of geometric center points of cross sections of adjacent conductors from one another is at least twice as large as an equivalent diameter (d, dequiv) of one of the conductors, and each busbar respectively comprises a connection region for electrical and mechanical connection of the connecting element to an electrical device. In addition, the connecting elements are arranged in parallel with one another and the geometric center points of the cross sections of adjacent conductors of adjacent connecting elements, which are assigned to different phases, have a spacing (b) from one another that is in each case at most half the product of the number (N) of electrical conductors minus 1 multiplied by the spacing (a) of the conductors of a phase from one another.
