Live Tank Circuit Breakers up to 800 kV
The GL series is safer and more reliable that previous circuit breakers designs. It offers a new generation of spring-spring operating mechanism that enables quick and easy onsite installation.
This range of Live Tank Circuit Breakers can be used everywhere in the energy field even in highly seismic, highly polluted and low temperature environments. The breakers benefit from single and three pole application and their low energy operation makes them a cost-effective option.
The GL Live Tank Circuit Breaker range includes breakers using single or double motion technology and reduced chamber size. Both, porcelain and composite insulators are available.
