WARRANTY

2-Pole Steam/Gas Turbine Driven Turbo Generators

• Ratings range from 6,000kW to 120,000 kW, 0.8–0.9 P.F. and include 50Hz at 3,000 rpm and 60Hz at 3,600 rpm.

• Custom engineered to match your mechanical, electrical and site requirements.

• Enclosures available include TEWAC (Totally Enclosed Water Air Cooled), room air cooled and hydrogen cooled to fit various applications requirements.

• Duraguard VPI (Vacuum Pressure Impregnation) insulation is fully Class F rated and uses a split component epoxy-mica system to provide industry proven long life.

• Robust design coupled with state-of-the-art, rated speed, dynamic balancing provides the lowest levels of vibration which results in smoother/longer life.

• Brushless excitation without collector rings or brushes provides maintenance-free operation.

• High voltage terminal boxes can be top, side or bottom mounted to accommodate customer installation requirements.

• Fully assembled and tested at rated speed and voltage while running in its own bearings to demonstrate conformance to customer requirements.

• All designs incorporate the features to meet the rigid requirements of cyclic-duty, rapid loading and peaking applications.

• Custom designed to match steam or gas turbine drives.

• Various mounting arrangements are available to match different OEM turbine interface requirements.

ExperienceConverteam EM has built over 1,000 units since 1947; representing over 20,000 MW of installed capacity worldwide.

Stator CoreThe frame is engineered, welded andmachined to withstand forces exerted byelectrical and mechanical stresses in thecore.

A “thin” cylinder support providesflexibility in the radial direction as well asstrength in the tangential direction. Above16,000kVA, flexible core mounting is usedto isolate low frequency vibration fromthe foundation.

Core laminations are punched frominsulation-coated electrical steel. Spacerlaminations are stacked into the core atregular intervals to provide openings forradial ventilation to ensure even coolingthroughout the core.

Stator coils are form-wound and vacuumpressure impregnated to meet Class Finsulation requirements. This systemprovides outstanding dielectric properties,superior moisture and chemical resistance,superb mechanical integrity and provenlong life.

Brushless Excitation SystemThe shaft mounted brushless exciter isprovided with permanent magnetgenerators, redundant fused diodes, andground detector system to providemaintenance-free, reliable operation.Voltage regulators offered by Electric Machinery or manufacturer of your choice.

RotorThe rotor is forged from high quality,vacuum degassed alloy steel. Forging istested for ductility, tensile strength andchemistry. Ultrasonic tests are made todetect subsurface flaws.

Rotor coils are formed from silver-bearingstrap copper to reduce dimensionalchanges under various load conditions.Each turn is individually insulated priorto winding.

After winding, coils are pressed andheated to bond the insulation. A solidconfiguration is formed which allowsuniform movement of the coils undervarious loading conditions.

Air is forced into the rotor body, where itpasses through the ventilation slots, andis discharged through spacer laminationsin the core to provide uniform cooling.

Rotor shaft journals are precision machinedand burnished. Coupled with precisionbalancing at rated speed, this enablesElectric Machinery to meet the most stringentindustry requirements for balance andvibration.
