Abstract :
Some 110 kV arrester base-plate isolator in the 110 kV electric substation dominated by power transformation Dept.1, Foshan power supply bureau, burst frequently in the last years. The most serious one ruptured just working three months. This paper talks about the cause of disruption, the settlement and the effect of crack control.
