Transmission line audible noise and corona reducing device

Claim 1

In combination: an overhead high voltage transmission line conductor extending between spaced supports, and a device for reducing corona and audible noise mounted on said conductor, said device including a plurality of preformed electrically conductive members each having opposite end sections being mounted on the transmission line conductor at a location between and spaced from the supports, and each having a helical configuration with the internal diameter of the helix generally being equal to the outer diameter of the transmission line conductor with the ends of the conductive members being held in tight gripping relationship on the conductor; the intermediate section being arcuate and having a radius of curvature greater than the radius of the conductor and being spaced from the conductor; said intermediate section being integral with the end sections and extending generally longitudinally along the axis of the conductor between said end sections; the end sections of said conductive members being disposed at intervals in circumferential relationship on the conductor; the radiI of curvature of said intermediate sections generally being equal to each other and forming an open cage-like body coaxial with the conductor, with said intermediate sections being spaced from each other and from said conductor; and the cage-like body being free of any intervening material between said intermediate sections and the conductor thereby reducing the weight and wind resistance of the device.
