High voltage corona ring design is the basic and important part on corona control project. Aluminum corona rings and grading rings are mainly used in power transformer bushing, high voltage laboratory, impulse voltage generator, insulator, surge arrester and other high voltage systems. It is easy to operate, convenient to move, and fast to install. Here…
When it comes to aluminum corona rings production process, Highv’s 30 years of manufacturing experience will really show.
From the beginning of 2017, China XD Group decided to invite bids for their new center high voltage testing project. Corona ring and shields were made by Highv which were successfully performed in Xian XD high voltage laboratory testing hall. We appreciated all group members efforts for China High Voltage development.
