Serie G2R

Alternators and PTO’s

  • 8 a 1700kVA
  • 4 Poles
  • 380 to 600 Volts

ACCORDING TO STANDARDS

  • IEC 60034-1
  • VDE 0530
  • BS4999-5000
  • CEI 2-3
  • UTE NFC 51-100.111
MECHANICAL CHARACTERISTICS
  • Steel casings and shields in gray cast iron.
  • High strength steel shaft.
  • Sturdy design of the rotors suitable for the running speeds of the drive motors.
  • Dumper cage for single-phase and / or distorted loads.
  • Self-lubricated bearings.
  • Brushless exciter and easy to disassemble.
  • Couplings B3 / B14 y B2.
  • All standard SAE couplings.
  • Ventilation: Axial, with air intake from the side opposite the drive.
  • Sense of Rotation: Both.
  • Mechanical Protection: Normal IP 23 (on request, other forms).

Class H insulation
Impregnation: VPI (vacuum and pressure).
Enamelled wires 200 degrees.
The voltage is automatically adjusted by an electronic regulator fed by a special winding, isolated from the main, which protects it from service surges.
Windings with 2/3 shortened pitch that guarantee low harmonic distortion and parallel operation with reduced neutral currents.

  • Voltage Accuracy: From no load to full load, cos fi 0.8: ± 0.5% for constant speed.
  • Engine Starting Capacity: 1 HP for each kVA of the alternator.
  • Transient Voltage Dip: Less than 18% when the full load is applied to cosine fi 0.8.
  • Single phase load: Up to a power equal to 0.65 of the normal three-phase catalog.
  • Frequencies: 50 or 60 Hz.
  • Voltages: Alternators are normally supplied to 12 star terminals with accessible neutral. Special voltages upon request.
  • Manual Voltage Adjustment: ± 5% of the nominal value. An external rheostat can be connected to do it remotely.
  • Waveform: Total Harmonic distortion less than 4% for L-N voltages with no load or three phase balanced linear loads.
  • Radio Interferences: Normally they are G grade according to VDE 0875 standards. Grades N and K, on ​​request.
  • Telephone Interferences: THF lower than 2% (BS 4999). Lower TIF 50 (ASA C 50.12).
  • Short Circuit Current: Greater than 3 times the nominal.
  • Parallel Device: G2R 250 and larger are provided with AVR prepared for parallel operation with other alternators of the same or different brand.Bellow G2R 250, on request.
  • Ratings: The values on the rating charts ​​refer to the following conditions: maximum ambient temperature 40 ° C, Altitude no over 1000 m a.s. and cos fi 0.8.

At an altitude higher than 1000 m.s. Is necesary a power derate of 4% every 500 m of increase.
At room temperature greater than 40 ° C, it is necessary to derate the power 4% every 5 degrees of increase.
Overloads: 10% overload for 1 hour every 6 hours. Larger overloads can be accepted for short times. (2.5 times the rated current).

  • Control panel
  • Air filters
  • EMI filters
  • Voltajes especiales
  • Thermometers.

On request other specialties and / or accessories are possible.
