Abstract:
An apparatus for deconcentrating an electric field surrounding a high voltage insulator comprising:a corona ring; and a clamp assembly for mounting said corona ring to an insulator end fitting of a high voltage insulator said clamp assembly for engaging an annular bell on said insulator end fitting wherein said clamp assembly further comprises an integral cross member connecting interior edges of said corona ring, said integral cross member forming a clamp seat at a central portion of said cross member, said cross member defining a first U-shaped opening therein, two keeper clamps pivotally mounted to said clamp seat, said keeper clamps defining a second and third U-shaped opening, said second and third U-shaped opening s being of a dimension smaller than said first U-shaped opening, and fastening means for securing said keeper clamps subjacent said clamp seat, wherein said second and third U-shaped openings are capable of receiving said insulator end fitting only on one side of said bell, wherein said keeper clamps are pivotally mounted about an axis passing through the integral cross member such that said keeper clamps rotate concomitantly in opposing direction between a first fixed position for receiving said insulator end fitting and a second fixed position for securing said insulator end fitting.
