The Voltage Grading Ring Plays An Important Role In Epoxy Resin Insulators

The grading ring improves the electric field distribution of high voltage standoff insulators, reduces the corona and radio interference of high voltage epoxy, and protects the shed of epoxy resin insulator from being burned in strong arc. The effect is more significant for high voltage level high voltage epoxy resin, making high voltage standoff play an important role in overhead transmission lines.
