For the distribution of electrical energy, Siemens offers various gas-insulated switchgear types. In compact substations or small distribution substations, such switchgear contributes to guaranteeing uninterrupted power supply through to households and small industries.

In all these applications, gas-insulated switchgear technology from Siemens provides exceptional advantages in respect of climatic independence, personal safety and maintenance-free design. For the power supply companies,  this offers the high benefit of maximum supply reliability in their networks and thus, satisfied customers.

Generator Switchgear

Generator Switchgear

High performance for the power supply of tomorrow

Independently of the type of power plant Siemens generator switchgear provide numerous advantages:

  • Increased cost-efficiency and service continuity
  • Optimum personal safety
  • Increased productivity
  • Environment-friendliness
  • Minimized installation and maintenance costs
  • Tailored solutions according to your requirements

Generator circuit-breaker switchgear (GCB) with vacuum switching technology is used in hydro, pumped storage, gas-fired or steam power plants, as well as in coal-fired, solar thermal and geothermal power plants. It offers solutions for retrofit projects as well as for new power plant constructions. The customers profit from continuously increasing cost-efficiency and uninterrupted operation.

Medium-voltage outdoor systems

Maximized reliability and minimized operating costs

Medium-voltage outdoor switching devices are essential components of medium-voltage distribution grids with overhead distribution lines. Siemens’ outdoor vacuum circuit-breakers (OVCB) protect overhead lines in case of a temporary fault and reduce outage times and the number of affected customers. Outdoor vacuum circuit-breakers offer systems for overhead distribution lines as well as for substations.

Siemens’ comprehensive portfolio of outdoor vacuum switching devices has been especially designed for a wide variety of climatic conditions. Type-tested reliability as well as long electrical life and mechanical robustness increase the profitability of medium-voltage grids. They offer the greatest possible benefit for every application, from the optimization of less developed network environments to the use in future-oriented smart grids.
