STC Series three phase A.C.synchronous generator Stc 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 star 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 voltage generator according to necessary. This series generators adopt with the jb/t8981-1999 standard, also accord with the iec34-1 standard. Environment conditions: Under the following conditions, the generators could continuously run and output the rated power: 1. Above sea level: not exceed 1000m 2. Cooling air temperature: 258 ~ 313 k 3. Relative air damping:90% Wooden case
