1.When the steam turbine thrust pad, the support bearing bushing, hydrogen cooled generator sealing pad are installed, the metal wall thermal resistance shall be installed and the leading wire shall be laid well. Before the pad is covered, the thermal resistance shall be re-checked to see whether it is damaged and whether the leading wire is dropped or not. 

2.Before the front box, middle box and cover of the steam turbine are buckled, the measuring elements of axial displacement, relative expansion, shaft vibration and rotating speed of steam turbine, the components of solenoid valve and position switch etc. must be installed and wired. 

3. Before the rotor is through the generator and the end cover is buckled, check and test whether the generator coil and iron as well as the new temperature-measuring element are damaged or not, check whether the insulation is good or not, and install the temperature-measuring element for the cold and hot air and the outgoing line.
