The document describes the features and characteristics of a product.
Siemens offers the SGen‑1000A series of air‑cooled, two‑pole generators for steam and gas turbines, covering ratings from 165 MVA to 350 MVA. The design builds on more than 100 years of experience and incorporates patents from the former Westinghouse Power Generation Business.
The generators feature modular rotors, multiple cooling options (air, OAC, TEWAC), IP55 outdoor‑ready enclosures, and rail‑transportable dimensions. Efficiency reaches up to 98.94 % at rated load, and the system uses a GVPI insulation system for high reliability.
