GL 314 BPS

High Quality Components

The GL 314 BPS live tank circuit breaker provides high reliability based in part on high quality components, including:

• Three pole operating design
• One self-blast interrupting unit with guard rings at  upper and lower positions
• Supporting column is composed of two to four insulators (depending on the voltage to ground/earth)
• Spring mechanism FK3 equipped with a position indicator visible from the outside
• Field-proven, temperature-compensated density monitor with two-stage transducer and three-color dial
• Easy access to the SF₆ filling connection (type DILO)
• Sealings suitable for temperatures down to -50 °C
• Hot-dip galvanized steel parts and mechanism housing made completely of aluminum

Optional Components

• Standard low voltage equipment provided, additional equipment is available
• Composite insulators are available
• Seismic dampers for high seismic request can be provided
• Pressure relief system for passive protection of both substation and personnel
• CBWatch: compact and modular circuit breaker monitoring solution

Installation and Maintenance

• Preset at factory before shipping; no adjustments necessary during installation and commissioning
• Disassembly of interrupter chamber without removal of entire pole column possible

Advanced Testing

The by-pass switch meets the requirements of national and international standards. This has been confirmed by comprehensive type tests according to the latest versions of IEC standards.

Certified Quality

GE's quality (ISO 9001:2008), environmental (ISO 14001:2004) and occupational health and safety (OHSAS 18001:2007) management systems determine the development and production procedures for the high voltage switches.
