Detail Information

Grading ring is a ring-shaped protective fitting designed to improve the voltage distribution of insulator strings. The function of the grading ring is to prevent lateral lightning strikes. It is suitable for AC voltage applications and is used to evenly distribute high voltage around an object, ensuring there is no potential difference between different parts of the ring, thereby achieving the equalization of voltage.


Grading rings can be categorized based on their applications, including lightning arrester grading rings, lightning protection grading rings, insulator grading rings, transformer grading rings, high-voltage testing equipment grading rings, and transmission and distribution line grading rings, among others. They can also be classified based on the materials used in their production, such as stainless steel grading rings, iron grading rings, aluminum grading rings, and so on.
