What is Grading Ring?


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. Corona ring installation is the normal solution to the problem of uneven potential field density distribution at insulator high voltage end. Installation of corona ring helps to transfer maximum field density from insulator surface to corona ring surface, thus effectively improves electric field distribution on insulator surface.

4.Q:How does you factory do regarding quality control?
A:HighV people always attach great importance to quality controlling from the very beginning to the very end. We could do the pre-shipment inspection for you.
5.Q:How about the shielding grading ring surface treatment?
A:Hot Galvanized/Polished Bright.
6.Q:What's painting of the grading ring?
A:During normal processing, the grading ring is made of the aluminum and steel. The surface finish does not require the painting.
HighV supply painting service according to customers requirement.
Such as Color painting, Galvanized etc. Other Tungsten plating, copper plating, etc, are available.
