ABSTRACT:
A corona shield for tension insulator assemblies for use in extra-high and ultra-high voltage overhead transmission lines comprises shielding rings at anchored ends of conductors consisting of a plurality of rings arranged in planes substantially along the longitudinal direction of the conductors so as to surround them and further at least one ring horn arranged perpendicular to the conductors at energized ends of the insulator strings anchoring the conductors, thereby preventing corona discharge from the insulators and line hardware on the energized side of insulator assemblies.
