Live Tank Circuit Breakers from 100 kV to 145 k
Live tank circuit breakers for outdoor installation are designed for temperatures down to -60 °C and feature the latest technologies in interrupter chambers and spring-operated mechanisms. For example, the latest double motion technology effectively reduces the opening energy by approximately 65 %.
High 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 live tank circuit breakers.
Quality
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.
Customer Benefits
High reliability even in the coldest regions of the world:
Down to -40 °C with pure SF6 Down to -60 °C with gas mixture
Quick and easy installation and commissioning
Long maintenance intervals
Components
• Interrupter chamber with integral double motion technology and self-blast system
• Pressure relief system for passive protection of substation and personnel
• Field-proven, temperature-compensated density monitor with two-stage transducer and three-color dial
• Easy access to the SF6 filling connection (type DILO)
• SF6 non-return (check) valve on each pole column
• Protected opening springs inside each pole column
• Hot-dip galvanized steel parts
• Mechanism housing made completely of aluminum
• Reliable spring-operated mechanism with position indicator clearly visible from outside
Installation and Maintenance
• Preset at factory before shipping - no adjustments necessary during installation and commissioning
• Pole units pre-filled with SF6 at factory before shipping
• Independent disassembly of the interrupter chamber without having to remove the entire pole column
• Single-pole operated circuit breakers partially pre-assembled before delivery (base frame with mounted and wired mechanisms)
Testing
Our 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.
