Upgrade your power plant with a vacuum GCB


Product information

A well rounded portfolio for all types of power plants

Whether you’re planning a retrofit project or will be building a new power plant, plan your work with an experienced partner. For more than 25 years, Siemens has been systematically advancing generator switchgear with vacuum switching technology in the power range from 10 MW to 400 MW. And tested, especially long-lasting components maximize operating safety and availability.

Discover the best solution for your application. For high terminal and mechanical loads in generator switching applications in nearly all types of power plants.

HB3 generator switchgear: with single-phase encapsulation for power plant units up to 400 MW

Especially safe for the power range up to 400 MW: the HB3 generator switchgear

Maximum safety for people and equipment: the HB3 generator switchgear is the world’s first to have a vacuum generator circuit-breaker. For up to 12,500 A with natural cooling and a type-tested switching capacity of up to 100 kA. Thanks to its single-phase encapsulation, short-circuits between the phases are eliminated.

The switchgear can also be smoothly integrated in the generator leads. The phase spacing and diameter of the single-phase, encapsulated IPBs are flexible. The switchgear can also be operated with the overpressure needed for the IPB system.
