Siemens Dead Tank Circuit Breakers Air-insulated switchgear

SIEMENS DEAD TANK CIRCUIT BREAKERS- AIR INSULATED SWITCHGEAR

We deliver dead tank circuit breakers for applications from 72.5 kV to 550 kV with a service life of up to 50 years. Our DT circuit breakers deliver the greatest possible reliability – even in extreme environmental conditions. The interrupter unit in this technology is located in a grounded metal-enclosed housing.

All construction types of our dead tank circuit breakers consist of the same basic components: 1. Bushing; 2. Current transformers; 3. Interrupter unit; 4. Operating mechanism cubicle; 5. Control cabinet

Dead Tank Circuit Breakers Main features:

  • Toroidal-core current transformers on bushings (compact construction)
  • High short-circuit breaking currents possible (up to 90 kA with one interrupter unit)
  • Low center of gravity of the bases (higher seismic withstand capability)
  • Gas-insulated components ensure highest availability with minimum maintenance effort
  • Metal-enclosed interrupter unit (grounded housing)
  • Available with porcelain or composite insulators
  • Suitable for temperatures from -60 to 55°C with mixed gas solutions or various heating systems
  • High seismic safety up to 0.5 g
  • Suitable for altitudes of up to 1,000 meters

Advantages:

  • Gas leakage rate of less than 0.1 % per year
  • Inspection after 12 and maintenance after 25 years
  • 10,000 switching operations are guaranteed
  • Product life time of up to 50 years
  • Easy installation and commissioning: only few assemblies
  • Installation, commissioning, maintenance, training and technical advice from a single source
  • Guaranteed availability of spare parts for all Siemens circuit breakers for a minimum of 25 years after delivery
