BIRD EXCREMENT SHIELDS FOR ELECTRIC POWER TRANSMISSION TOWERS

Last updated:

Abstract:

A shield system for an electric power transmission tower includes a plurality of panels configured to be secured to a cross-arm structure of the tower in adjacent, end-to-end arrangement so as to overlie insulators supported by the tower and prevent excrement from birds nesting and/or congregating on the tower from contacting and accumulating on the insulators. Each panel has opposite ends and opposite lateral edges extending between the opposite ends. A plurality of spaced-apart apertures are formed in each panel adjacent each of the lateral edges and at least one of the ends, and each aperture is configured to receive a respective fastener therethrough for securing the panel to the cross-arm structure. Each panel has a shape that generally conforms to a shape of a portion of the cross-arm structure to which the panel is secured.
