A Corona Ring is a circular conductive material, usually metal, which is attached to a terminal of high voltage equipment. The function of the Corona Ring is to distribute the electric field gradient and lower its maximum values below the corona threshold and thus preventing corona discharge


Powder coating gun with corona ring provides higher transfer efficiency for better surface quality. When coating profiles, radiators, lamps, rims etc. the coating result is exceptional, using a corona ring can overcome the all difficulities. By coating with several powder types, an "orange peel" finish can be completely avoided. By coating with structure powder, the "picture frame effect" is hardly visible.
