Dead tank compact (DTC) overview

The dead tank compact (DTC) circuit breaker for 145 kV and 245 kV applications is a compact arrangement of several functions needed in a substation. The hybrid concept combines SF6-encapsulated components and air-insulated components. It is possible to arrange the components in a variety of ways depending on your substation configuration.

Flexible solutions according to your substation configuration

  • CB with single- or three-pole operating mechanism
  • Disconnector, earthing switch, high-speed earthing switch
  • Current transformer, voltage transformer and voltage detection system
  • Cable connections possible at various positions
  • Bushings available as porcelain or composite insulators
  • Additional separation of gas compartment, with SF6 density monitor on request
  • Double breaker modules for ultra-compact substation designs
  • Possibility for stand-alone components, e.g. disconnector module with VT

Advantages:

  • Flexibility in confined spaces and extreme environmental conditions
  • GIS components ensure the highest availability and safety at minimum maintenance effort
  • Optimized investments acc. to individual substation requirements
  • Minimum design work for various applications thanks to predefined modules

Our dead tank compact circuit breaker family

Based on our modular design, the core components are adopted from our high-voltage circuit breakers, disconnectors and the GIS product family. Our dead tank compact circuit breakers have a three-pole operating mechanism with a common base, or single-pole operating mechanism on separate bases.
