Due to the high power demand in modern, passenger-carrying rail traffic, the previous solution from the prior art is outdated and inefficient. Especially in the case of heavily stressed contact elements, such as in the area of rail-bound traffic, there is an increasing need for repair and maintenance due to ever-increasing requirements, for example due to increased electrical erosion or electro-corrosion due to the high currents of over 500A up to a few thousand amperes and voltages from over 500V to several kilovolts.
