Live-tank circuit breaker GL 107X

spring operatedSF6 gas-insulatedhigh-voltage

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: •Third-generation self-blast interrupter chamber •Operating linkages in one common gas enclosure forming part of the base frame •Only one seal is dynamically stressed •Insulator flanges sealed with Portland cement •Pressure relief system for passive protection of both substation and personnel •Compact design in line with considerations of current transformers •Field-proven, temperature-compensated density monitor with two-stage transducer and three-color dial •Easy access to the SF6 filling connection (type DILO) •Extruded aluminum base frame •Reliable spring-operated mechanism with position indicator clearly visible from outside
