Lube oil can not leak in stator housing. There is only one main fan of generator rotor. It is convenient to install generator rotor in stator. The suspend stator core reduces vibration influence to stator housing. Laminated press plates at two sides of stator core that have same material as stator core reduces flux loss at two ends greatly. Temperature rise at end of stator core is controlled well. Leading phase operation ability is very high. Operation is not limited by time at leading power factor 0.95. There is re-tight device at end windings to ensure tight condition all the time during generator operation life. There is re-tight design in stator slots.It ensures the bars in slots are tightened during operation life. TVPI technology of stator bar manufacture guarantees stator bar insulation integrality and good heat conductivity. Stainless steel hollow conductor avoids to be clogged by CuO2 that cause copper hollow conductor clogging. Closed air cooling system with filter and hum
