ST/STC Series Single/Three-phase Synchronous generaotr have been awarded the national gold medal in recognition of their superiority in quality. ST/STC series generators are mainly designed to serve as power generating unit of small capacity,which supply electricity for lighting purpose in ships, for house-hold electric used in towns or villages. The construction of the generators id of drip-proof, salient pole rotating field self excitation and constant voltage type. The alternator is adopted with high qualty electric magnetic and electrical materials. stator insulation is class B. These generators are elegant in appearance, light construction and easy maintenance. IEC standard are adopted on dimension, these dimension are suitable for using in Australia, Europe, America and other countries with the end covers to be model B. The generators adopt harmonic wave self-excitaion constant voltage system and automatic voltage control excitation constant voltage system, both of them have excellent dynamic characteristic performance, convenient and reliable in operation.
