ST series generators are mainly designed to serve as power generating unit of small capacity which supply electricity for lighting purpose in ships as well as for household electric devices used in towns or villages.

The construction of the generators is of drop-proof type, salient pole rotating field self-excitation and constant voltage type. The alternator inside is used with high quality electric magnetic and electrical materials. Stator insulation is of Class E(or B).rotor insulation is of Class B. These generators are excellent in appearance. they are consolidate in construction and easy to maintain. Europe, America and other countries if the end covers are model B.

The alternators are of harmonic wave self-ex-citation constant voltage system and automatic voltage control excitation constant voltage system, both of them have excellent dynamic characteristic performance, convenient and reliable in operation.
