Siemens SGen-100A-2P series air-cooled generators are used in various types of power plants, including coal-fired power plants, gas-fired power plants and steam turbine generators.
The SGen-100A-2P series is a two‑pole, three‑phase synchronous generator range designed for fossil‑fueled power plants, including gas and steam turbines. Siemens offers a building‑block system that lets customers select rotor diameter, length and cooling type to match specific project requirements.
Technical features include brushless or static excitation, double‑layer stator winding with epoxy‑mica insulation, and various cooling options such as TEWAC, CACA or DAC. The standard design follows IEC 34‑7 (IM 7215) and provides high efficiency (up to 98.7%), low noise emissions and long service life.
| Apparent Power (50 Hz) | 25 MVA to 300 MVA |
|---|---|
| Apparent Power (60 Hz) | 25 MVA to 235 MVA |
| Power Factor | 0.80 to 0.85 |
