1 High-Current and Generator Switchgear Reliable and cost-efficient in every way Answers for energy.

2 Siemens Partner of the power plant sector The growing energy demand calls for more and fail-safe power from the power plants and the cost pressure on the market demands a higher efficiency in the provision of energy. As a pioneer for vacuum switching technology, Siemens has developed solutions and technologies for the reliable transmission and distribution of electrical power from power plants to consumers for more than 30 years. The resulting comprehensive know-how is reflected in our high-quality solutions and services. Be it availability, cost-efficiency or safety: As power plant builders or operators you are confronted with maximum requirements at all times. So, it is just reasonable to expect the same from crucial components such as the generator switchgear. Therefore, generator switchgear from Siemens offers maximum efficiency and safety on the whole as well as for every single component, e.g. especially for the centerpiece of the switchgear, the generator vacuum circuit-breaker: To guarantee availability and performance, high-current and generator switchgear assemblies are equipped with circuit-breakers that withstand maximum stress. Switchgear details that pay off: Our high-current and generator switchgear with the proven vacuum switching technology from Siemens is designed to withstand maximum normal currents, featuring durable contact materials, an optimized design in respect of cooling as well as maximum mechanical stability. The generator circuit-breaker meets the severe requirements of the generator circuit-breaker standard IEEE C37.013, demonstrating its outstanding qualities. This increases the performance, reliability,and cost-efficiency of the complete generator switchgear. 2

3 More functionality lower costs With the highly integrated generator switchgear, Siemens enables more functionality on less space. For the first time, the neutral treatment of the generator as well as the auxiliary feeder are integrated in a single generator switchgear. The switchgear can be installed both indoors and outdoors: close to the generator, without expensive cabling. All functions are therefore available out of one hand without time-consuming coordination between different suppliers, which offers considerable cost savings due to lower expenditure for planning, investment, and installation lower demand for space, material (cabling), and service More safety and reliability from Siemens With our generator switchgear you are always on the safe side. Regardless of the switchgear type you decide for, you will obtain: High reliability due to the intelligent and proven switchgear design and the use of reliable components tested to the standards High security of operation due to clear switching operations High personal safety due to safety-oriented design of the switchgear High cost-efficiency due to maintenance-free or low-maintenance components More efficiency with powerful circuit-breakers High mechanical stability Low fire load due to omission of solid insulation Without forced cooling up to maximum current ratings thanks to the utilization of natural convection Ecological and, at the same time, operationally safe vacuum switching technology 3
