  • Device for establishing a multi-phase electric connection and an arrangement comprising corresponding devices
    Patent number: 10193284
    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.
