| Abstract: | Aiming at the accident of post porcelain insulator rupture in 220 kV isolating switch,made the field test and analysis, From technology and management aspects puts forward to prevent thesuggestions of post porcelain insulator rupture. The analysis result shows that insulator rupture iscaused by its bending strength insufficient and not according to technology request to lay on the bitu?men layer. |
