Siemens generator switchgear for a power range up to 400 MW is the result of more than 25 years of continuous development and more than 40 years of experience in vacuum switching technology. It fulfills the highest technological and quality requirements.
It provides numerous advantages, independently of the type of power plant. Due to the use of tested and durable components with a service life of more than 20 years, a high level of operating reliability and availability is achieved that leads to increased profitability. The maintenance-free vacuum switching technology and components in the generator switchgear guarantees minimum maintenance costs.
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.
The advantages for your power plant are:
Reliable synchronization and power plant optimization
Increased cost-efficiency and service continuity
Optimum personal safety
Minimized installation and maintenance costs
Tailored solutions according to your requirements
