STC Series three-phase a.c. synchronous alternators are mainly designed to serve as power generating unit for lighting purpose in villages , towns, and house-hold electric appliances or standby power.The construction of the generators are salient-pole rotating field , self excitation with 3 phase harmonic .

GP-S series three-phase brushless excitation synchronous alternators by introducing and developing on foreign advanced technology of well-known alternators, like Stamford alternators etc, The generator set by coupling the alternator with engine is mainly designed to serve as power supply in national defence , post and telecommunications, hospital, hotel, market and factory as electric appliances or standby power. The generators are made as per standard JB/T3320.2-2000 and in conformity to IEC34-1
