Abstract
An improved apparatus for deconcentrating an electric field surrounding a high voltage insulator. A clamp assembly centrally formed within a coronal ring permits positive placement of the coronal ring about an insulator end fitting. The clamping assembly comprises an integral clamp with a u-shaped opening for engaging a cylindrical portion of an insulator end fitting. A keeper clamp mounts superjacent to the integral clamp and a smaller second u-shaped opening engages a portion of the insulator end fitting having a smaller diameter. A captive fastener such as a bolt extends upwardly through the clamp and keeper clamp to secure the keeper clamp in position against the insulator end fitting and the integral clamp to secure the corona ring in position relative the insulator end fitting and sheds. The varied sized openings of the clamp and keeper clamp prevent inverted installation of the corona ring.
