Live Tank Circuit Breakers

GE offers highly reliable live tank circuit breakers for air-insulated substations up to 800 kV. The GL series features advanced switchgear technology with self-blast interrupters and spring-operated mechanisms (type FK) to ensure safe and efficient operation.

The field-proven interrupter design features the energy-optimized self-blast principle with single or double motion technology. The FK mechanism equips all GE high voltage circuit breakers with more than 250,000 drives in operation worldwide today.

This range of live tank circuit breakers can be used everywhere in the energy field even in highly seismic, highly polluted and very low temperature environments. All breakers are tested according to international and national standards to ensure the highest quality and reliability.
