Analysis On The Causes Of Fracture Of High Voltage Epoxy Resin Insulators
Date: | Read: 15
As mentioned above, the main reasons for the breakage and fracture of high voltage standoff insulators are high voltage epoxy factory defects; epoxy resin insulator damage during packaging, transportation and installation; high voltage epoxy resin operation in harsh environments, the difference in expansion coefficients between the electric porcelain, cement and cast iron flanges, coupled with temperature differences, leading to high voltage standoff cracks.
