Characteristic:

1.Optional auxiliary winding system provides sustained short circuit capability;

2.Advanced automatic voltage regulator(AVR) control for trouble-free operation under the most

  demanding conditions;

3.Easy paralleling wiht mains or other generators;

4.Standard 2/3 pitch windings avoid excessive neutral currents;

5.Dynamically balanced rotors, with sealed-for-life ball bearing and single or two-bearing

  construction.

6.Simple installation and maintenance, with easy access to terminals, rotaing diodes and

  coupling bolts;

7.Built to conform with all leading industrial standards.

Electrical specification:

   Excitation systems TP460&TP465 AVRS.

Insulation/Impregnation:

1.The insulation system is class "H";

2.All generator stators are wound to 2/3 pitch;

3.Telephone interference (as fefined by BS4999 part 40)is better than 210.TIF(as defined by

   ASAC50.12)is better than 50;

4.The absence of brushgear and the hign quality AVR ensure low levels of interference with radio transmissions. Additional RFI suppression may be supplied if required.

5.Standard generators are 3 phase reconnectable with 12 ends brought out to the terminals, which are mounted on a cover at the non-drive end of the generator. A sheet steel terminal box contains the AVR and provides ample space for customer's wiring and gland arrangements, it has removable panels for easy access.

Enclosure:

 IP23(NEMA1) is standard for all industrial and marine generators.

Shaft and keys:

  All generator rotors are dynamically balanced to better than BS6861: Part 1 Grade 2.5 for minimum vibration in operation. Two bearing generators are balanced with a half key.
