Product Description

550kV Aluminum Grading Ring/ Corona Ring for Composite Insulator

Brief Introduction:
The design of the corona ring is done by accurate digital assimilation in order to reduce and to balance the electrical field around and on the insulator's sheds. The corona ring is made of aluminum which is resistant against harsh weather conditions; it is polished for the reasons of reducing Corona and partial discharge. The utilized bolts and arms in Corona ring are all made of stainless steel in order to be anti-corrosion.

The special design of the Corona ring makes impossible any inaccuracy in its installation.
