Performance range 25‐370 MVA
Efficiency up to 98.9%
Highly efficient generator for sustainable power supply
Our air-cooled generator series offers you a competitive advantage by providing ratings of up to 370 MVA with operationally proven technology. The SGen-100A series with 25–180 MVA is optimized for industrial applications and the SGen-1000A series with 180–370 MVA for large power applications. We continuously improve our generators and focus on increased reliability, improved serviceability, high efficiency, and optimum plant integration. Our generator designs benefit from more than 150 years of engineering experience going back to the invention of the electrical generator by Werner von Siemens in 1866.
The entire SGen-100A/1000A series is optimized for world-class efficiency of up to 98.9% and stability during load changes and flexible operation. They are designed for 10,000 start/stop cycles during their operational life, making them a cost-effective alternative to hydrogen- or water-cooled generators for industrial applications up to 370 MVA.
Our experts have designed a product line that meets all major market and application requirements. By applying our modular design philosophy and using pre-designed options, we can customize your generator the way you need it with minimum lead time.
The proven Siemens MICALASTIC® insulation system with Global Vacuum Pressure Impregnation (GVPI) technology ensures maximum electrical endurance and outstanding availability.
- Insensitive to thermal cycling
- No maintenance required
- Very low mechanical stress during operation
- Non-flammable and self-extinguishing; no fire-extinguishing system needed
The SGen-100A/1000A series is designed and manufactured for ease of use. Our robust and proven design features pre-assembled components to shorten the commissioning period. The self-supporting structure of the base frame with integrated cover, machine auxiliaries, and exciter set facilitates easy on-site installation.
There are more than 1,000 air-cooled generators in operation. Our design, engineering, sales, project management, manufacturing and testing experts work closely together in one location in Erfurt, Germany. By using the latest manufacturing technology and process automation we ensure outstanding quality.
Our generators are designed using our building-block system with optimized diameter and length sizing to achieve perfect alignment with your plant and the grid requirements. Grid studies can be performed. Many more options are available including variants of the cooling system and the position of the generator leads. All parts and connections are readily accessible and the enclosure can be easily removed for installation or maintenance.
