 The generators are to be used in town,the countryside, worksites, mountain and pasture lands as a electric power source for lighting purpose,It can also be used as a reserved power source for emergent case.The generators are of drip-poof with rotary field type and with the adoption of harmonic excitation system, that allow your easy operation and simple maintenance.
The generators are of three-phase four-wire type, making use of atar connection with neutral point. The rated line voltage is 400V. phase voltage 230V. frequency 50Hz. power factor 0.8(lag). It can provide 60Hz and the other voltages generator according to necessary. They can be coupled with a prime mover directly or through V-belt making right or reverse continuous rotation at the rated speed. when the revolution slip of prime mover is 3% and load varies in the range of 0   100% cos F 1.0   0.8 they give food constant voltage. After sudden change (increase or decrease)of load. the generators will soon return to their normal working state. without any starting devices the generator can directly start an unloaded squirrel cage induction motor.

Operating conditions

Under the following environment,the generator could run continuously:

1.Altitude:not exceed 1000m

2.Ambient temperature:-15°C-40°C

3.Relative air humidity:≤90%

Operating Conditions:
Under the following environment, The generator could be continuous and rated running:
