Description: The Grading Ring is used to improve the voltage distribution of the insulator strings, ensuring that there is no potential difference around the ring.
The grading ring can be divided into lightning arrester voltage grading rings, lightning protection voltage grading rings, insulator voltage grading rings, transformer voltage grading rings, high voltage test equipment voltage grading rings, power transmission and transformation line voltage grading rings, etc. according to different uses.
According to different materials, the grading ring can be divided into aluminum grading ring, stainless steel grading ring, iron grading ring, etc.
