| Abstract: | On the condition that the insulation margin and the high relability remain the same as the original product,starting from improving the utilization factor of the dominant insulation of the core,by adjusting the electric field strength distribution in radial and axial direction to lower the non-uniformity of electric field strength,the initial partial discharge level is raised,hence the electric performance of220kV capacitive bushing is improved. |
