Operating conditions​
  • The generator can operate at rated power under the following conditions:
  • Altitude of no more than 1000 meters.
  • Cooling air temperature 258~313K (-15°C ~ +40°C).
  • Relative humidity not exceeding 90%.
​Features​
  • The optional permanent magnet generator and auxiliary winding excitation system is capable of withstanding short-circuit current.
  • The advanced automatic voltage regulator (AVR) control system guarantees reliable operation even under the harshest conditions.
  • Easy paralleling with the mains or other generators. The standard 2/3 pitch winding suppresses excess current in the neutral.
  • Dynamically balanced rotor with sealed ball bearings, available in single and double bearing structures.
  • Simple installation, convenient maintenance and service; easy-to-operate terminals, rotary rectifiers and coupling screws.
  • Multiple sizes of transition adapters and single bearing disk plate couplings.
  • Compliance with all major terrestrial standards.
