STC THREE PHASE GENERATOR
----------------------------------------------------------------------------------------------------
This series generators are to be used in town, countryside, worksites, mountain and pasture as electric power source for
lighting purpose, it can also be used as reserved power source for emergent case using.
The generators are of dripproof with rotary field type and adopt harmonic excitation system, easy operation and
maintenance.
The generators 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 generators 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
o
C ~ 40
