Hidden Dangers Of Cracking Of High-voltage Epoxy Resin Insulators
Date: | Read: 16
However, the three materials of high voltage standoff insulators have different linear expansion coefficients and thermal conductivity. Therefore, when the ambient temperature changes rapidly, the local position of high voltage epoxy will be subjected to greater mechanical stress, and sometimes the porcelain will break. At this time, the larger the volume of epoxy resin insulator and the more complex the structure, the greater the possibility of high voltage epoxy resin breaking and the severity of high voltage standoff.
