Live tank circuit breaker from 36 kV up to 40.5 kV
Highly Reliable Performance
GE’s GL 107X live tank circuit breakers for outdoor installation are provided with third-generation self-blast interrupter chambers and spring-operated mechanisms. The field-proven interrupter chamber operates on the energy-optimized self-blast principle. This live tank circuit breaker provides a high level of reliability for customers, even under extreme conditions and climates or in highly active seismic areas.
The GL 107X live tank circuit breaker is preset, pre-filled with SF6 and completely assembled at the factory before shipping (pole columns, base frame and spring-operated mechanism). Due to this preassembly, no adjustments are necessary during installation and commissioning of the circuit breaker which allows for quick and easy installation on site with long intervals between maintenance.
High Quality Components
The GL 107X live tank circuit breaker provides high reliability based in part on high quality components, including:
Installation and Maintenance
