sf6 base unit for railroad

Our complete 3AP family up to 800 kV and above relies on our arc-quenching principles, either the self-compression or the dynamic self-compression principle using the thermal energy of the arc. Siemens patented this method of arc quenching in 1973 and has continued to develop the technology of the self-compression interrupter unit ever since.
