The document describes the features and characteristics of Siemens' SGen-2000H series hydrogen-cooled generators, including their ratings up to 600 MVA for steam, gas, and combined-cycle applications. The use of hydrogen as a cooling medium enhances cooling performance and reduces frictional losses, improving overall generator efficiency and performance.
The SGen-2000H series is a hydrogen‑cooled, two‑pole generator line offered by Siemens for steam, gas and combined‑cycle power plants. The design uses thin laminations, advanced insulation, and a patented core‑spring mounting system to achieve high efficiency and reliability.
The document includes technical data such as frequency, apparent power, efficiency and terminal voltage, as well as information on coolant, enclosure IP rating, thermal classification and transport dimensions. Customer benefits, reference installations and contact details are also provided.
