The generators are three phase, open ventilated with a large terminal box suitable for easy connection to the terminals. Frame size range from 160 to 710 mm. These generators comply with the following standards:
- CEI EN 60034-1
- IEC 60034-1
- BS 4999-5000
- DE 0530
- NF 51-100,111
- OVE M-10
- NEMA MG 1.22
Main features
Auxiliary windings as standard up to 1300kVA (frame size 400mm). PMG available on request.
Three phase sensing AVR from 150kVA to 1300kVA. On all the other outputs on request.
Voltage precision +/- 0,5%.
2/3 Pitch Winding.
THD <= 2% up to 1300kVA (frame size 400mm).
Radio interference conforms to Class B Group 1 as defined by IEC 60034-1.
Icc > 3In up to 1300kVA (frame size 400mm), Icc > 2,5In above.
Class H Insulation System.
12 leads up to 660kVA; on request up to 1300kVA.
The generators are impregnated using the most modern technologies (Vacuum Pressure Impregnation). A further protection from any corrosion phenomenum is guaranteed by a tropicalisation treatment as standard on all generator series.
Standard mountings are B2 (single-bearing configuration) and B3/B14 or B3/B5. Special constructions can be supplied on request.
Standard enclosure is IP23. Higher protection levels (up to IP55) can be supplied on request using air filters or heat exchangers mounted on the generators.
MJB generators can operate at 50 and 60 Hz.
Low Voltage Generators 380 - 480 V; special voltage on request
10 - 4000 kVA
4 - 18 poles
Medium Voltage Generators 3000 - 6600 V; special voltage on request
400 - 6000 kVA
4 - 18 poles |
