ABSTRACT:
When dimensioning electrical plants for high voltages for regions exposed to earthquakes, it is necessary to design the current paths between the different apparatuses in such a way that the apparatuses in case of great oscillations are not subjected to abnormally great forces at the points of connection. The problem arises particularly in connection with convertor plants for high-voltage direct current designed with suspended valves, since the oscillating amplitudes there may become considerable. The invention relates to a current path intended for such plants, which is flexible its longitudinal direction and comprises at least two parallel, non-insulated straight conductors which are each connected to a respective end of the current path and electrically interconnectd via roller contact elements, the contact force of which is individually resilient.
