1.the construction of this series generators is of drip-proof type, ip21， salient pole rotating field self-excitation and constant voltage type. the stator insulation is of class b(or f) and rotor insulation is of class b.
2.the manufactures of generator are adopted standard jb/t 3320.2-2000 and also meet the dimensions of iec standard. they will satisfy the market needs of australia、europe、america、 and other countries if the end covers are of model b.
3.the generators are of harmonic wave self-excitation constant voltage system and automatic voltage control excitation constant voltage system. both of them are excellent dynamic characteristic in performance, convenient and reliable in operation.
4.the voltage of the generators is 230v or 115v (if necessary it can be designed for 240v or 120v). the continuous duty frequency is 50hz or 60hz in operation.
