Advanced Switchgear Technology Live tank circuit breakers for outdoor installation are provided with third-generation selfblast chambers and spring-operated mechanisms. The field-proven interrupter chamber operates on the basis of the energy-optimized self-blast principle. High Quality Components • 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 cementnsulator 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 SFe filling connection (type DILO) • Extruded aluminum base frame • Reliable spring-operated mechanism with position indicator clearly visible from outside Enhanced Installation and Maintenance • Preset at factory before shipping - no adjustments necessary during installation and commissioning • Pole units pre-filled with SFe at factory before shipping • Circuit breaker completely assembled before delivery (pole columns, base frame and spring-operated mechanism) Rigorous Testing GE's live tank circuit breakers meet national and international requirement standards. This has been confirmed by comprehensive type tests according to the latest IEC, GOST and ANSI standards. Reliable Performance Live tank circuit breakers ensure a high level of reliability every day. Even under extreme conditions and climates or in highly active seismic areas customers can count on GE's live tank circuit breakers. Superior Manufacturing The entire development and production procedures are fully compliant with the latest ISO 9001, ISO 14001 and OHSAS 18001 quality standards. This ensures the high quality of our products and services and is confirmed by regular audits. Key Benefits • High reliability due to field-proven components and rigorous testing • Enhanced installation and commissioning thanks to complete assembly before delivery • Long maintenance intervals
