Product Name: Grading Ring
Application: Insulator/Surge Arrester/Bushing
Material: Aluminum/Stainless Steel
Grading Ring Specification
- Grading ring is suitable for the voltage form of communication, high pressure can be evenly distributed around the object, ensure no potential difference between each part of the ring, so as to achieve the effect of the equalizer.
- It can be divided by use different, such as insulator, surge arrester, current transformer, high voltage test equipment, power transmission and transformation line, etc.
- Grading rings are according to the material are qualitative different, can be divided into aluminum grading ring, stainless steel grading ring, etc.

Grading ring is also used on high voltage equipment. These are similar to corona rings, but they encircles insulators rather than conductors. Although they may also serve to suppress corona, their main purpose is to reduce the potential gradient along the insulator, preventing premature electrical breakdown.
1. Material: Aluminum/Stainless Steel
2. Operating Temperature: -80° C-80° C
3. Polishing Bright Surface Finish
4. Preventing premature electrical breakdown
The grading ring packing can be done by wooden case or carton box.
Wooden case packing is suitable for heavy weight ones.
Carton box packing is always for light weight rings. It is also convenient for delivering by hands.
