Electrical Performance Of Pin Polymer Insulator:
The destructive discharge along the insulation surface is called flashover. Flashover is the main electrical performance of pin insulator. For different voltage levels, the voltage tolerance requirements of pin insulators are different, and the indicators include power frequency dry, wet voltage, lightning shock voltage, lightning shock carrier voltage, operating shock voltage and so on.To avoid breakdown in operation, the breakdown voltage of the insulator is higher than the flashover voltage.
