Overview
The equalizing ring can improve the voltage distribution, and at the same time, the ring is discharged to the ground during the flashover, which can play a role in protecting the umbrella sleeve from being arc burned, and alleviate the aging of the umbrella sleeve at the live end. The high-voltage end of the 110kV product is equipped with a equalizing ring, but it is recommended to be equipped with equalizing rings at both ends in the multi-mine area; Products of 220kV and above voltage level have a voltage equalizing ring at the high voltage end and the grounding end.
