SGen-3000W
Generators with water-cooled stators and hydrogen-cooled rotors are optimal for the highest output ranges. Their compact design coupled with our unique direct water-cooled stator is suitable for large steam power plant applications ranging up to 1270 MVA.
| Frequency | Model | Power factor | Apparent power | Efficiency | Terminal voltage |
| 50 Hz | SGen5-3000W | 0.85 | 675 MVA to 940 MVA | up to 99 % | 15 kV to 21 kV |
| 60 Hz | SGen6-3000W | 0.85 | 600 MVA to 1,270 MVA | up to 99 % | 16 kV to 27 kV |
- Typically equal or more efficient than equally rated air-cooled model
- Smaller in size than equally rated hydrogen- and air-cooled models
- Not prone to contamination by dirt, oil and humidity
- Simple, low maintenance, primary water system with demineralized/pH controlled cooling water to suppress copper corrosion
- Bracket bearings and shaft seals arranged to minimize H2 leakage
- Frame arranged for ease of alignment and foundation loading
- Spring-mounted stator to minimize vibration transmission to foundation
- Pre-stressed, non-magnetic, through bolts minimizing the need for maintenance and re-tensioning of the core
- Stator bar tightness is maintained with pre-stressed ripple springs to avoid mechanical and electrical degradation
- Stator end windings surrounded by a glass-fiber cone for radial support
- Water-cooled stator winding to maximize output
- High-pressure multi-stage compressor blower for intense cooling
- Hydrogen-cooled rotor winding for high current (MVA) capability
