    Highlights of the SGen-3000W generator series

    Modern grids require high operational flexibility because of the increased integration of renewable energy sources. Our design supports high ramp-up/down rates, frequent start/stops while maintaining low thermal mechanical stress in the stator windings.

    Our proven MICALASTIC® insulation system and Global Vacuum Pressure Impregnation (GVPI) technology ensure maximum electrical endurance and outstanding availability.

     

    Your benefits:


    - Insensitive to thermal cycling
    - No maintenance required
    - Very low mechanical stress during operation
    - Non-flammable and self-extinguishing; no fire-extinguishing system needed

    Combining GVPI stators with water cooling enables uniform temperatures and low stress levels to enhance operational flexibility. The proven reliability is greater than 99.9% for more than 1,700 stator windings between 10 and 22 kV with an output of up to 1,300 MVA. Our fleet leader has over 150,000 operating hours and 3,320 start/stop cycles.

    Our generators display a high level of common parts across the portfolio (e.g. stator core assembly and rotor). The reusing of parts and components improves the availability of spare parts and increases the quality in manufacturing and assembly at our factory as well as on site.

     

     

     

    Generator technology

    The SGen-3000W implements technology featuring the latest verified design with more than 1,700 GVPI stators in operation across all operating ranges and a fleet-leading water-cooled GVPI stator with over 150,000 hours of operation and more than 3,320 start/stop cycles with no indication of thermal-mechanical stress-related  issues. Hydrogen cooling with water-cooled stator bars makes this generator series ideal for any operating regime.
