Application:

Compared to electric porcelain insulator, composite insulator is featured with high intensity, light weight, high wet flashover and flashover voltage, easy operation maintenance, strong ability of impulse withstand, widely applied to transmission line suspension string, and has spread application in tension string in recent years. Surface field distribution and potential distribution for composite insulator without corona ring is greatly uneven, due to composite insulator structure characteristics and high resistivity feature of silicon rubber, surface field density is highest at mandrel and steel cap joint, distribution voltage is highest at first umbrella dress near high voltage end. Exorbitant surface field density not only generate corona discharge, affect transmission line electromagnetic environment, produce audible sound pollution, but also cause strong electric erosion, causing further insulator aging. Grading ring installation is the normal solution to the problem of uneven potential field density distribution at insulator high voltage end. Installation of grading ring helps to transfer maximum field density from insulator surface to grading ring surface, thus effectively improves electric field distribution on insulator surface.
