The hydro-generators of Changzhou hydro-complex are arranged based on horizontal bulb structure. The main shaft supports are two supporting points and double-cantilever structure, which construct two supporting points and main shaft supporting mode by the radial bearing of turbine and a set of combined thrust and radial bearings set at the downstream side of the generator rotor. The generator adopts double closed loop forced air cooling method;and the secondary cooling system consists of axial flow fan, air cooler, centrifugal pump and conical cooling jacket etc.
