Stc Three Phase Alternator

This series alternators are to be used in town, countryside, work sites, mountain and pasture as electric power source for lighting purpose, it can also he used as reserved power source for emergent case using.
The alternators are of drip proof with rotary field type and adopt harmonic excitation system, easy operation and maintenance.
The alternators are three-phase, four-wire type, adopting star connection with neutral point. The rated line voltage is 400V, phase voltage 230V, frequency 50Hz. power factor 0.8(lag). We can provide 60Hz and the other voltage's generator according to the customer's request.
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 rotation speed of prime mover changs 3% or so and load varies in the range of 0~100% cos j 0.8~1.0, the alternators offer constant voltage, when sudden change (increase or decrease) of load, the generator will soon return to their normal working state, at the same time, without any starting device the generator can directly start an unloaded squirrel cage induction motor.

Operating Conditions:
Under the following environment, The generator could be continuous and rated running:
Above sea level: Not exceed 1000m
Cooling air temperature: 258~313K(-15 oC ~ 40 oC)
Relative air damping: not exceed 90%
