Application Of Equalizing Rings In Epoxy Resin Insulators

During the structural design phase, manufacturers select appropriate voltage equalizing ring sizes and materials based on the high voltage level and place them near the high voltage epoxy hardware terminals to improve the electric field distribution and reduce the electrical stress on the epoxy resin insulator skirt ring. In high voltage epoxy resin voltage levels of 220kV and above, setting one or two voltage equalizing rings can significantly improve the electric field distribution.
