The article introduces the optimize design insulate structure of 1250MW, 24kV grade nucleus generator stator module bar. The bars behave excellent characteristic. Breakdown strength mean value (60 second voltage endurance) is 26.5kV/mm; Strain capability at fracture is 2497.4 μstrain; There is no distinctness inflected of bending strength after 107 cycles at 600×10-6 strainP-P magnitude. The bars stringent checking test had passed. Nucleus generator can work 60 yeas at dependability, stability and security.
