Abstract
A wildlife guard, designed to prevent an electrically grounded animal, such as a bird or small mammal, from contacting energized electrical equipment. A one-piece construction fabricated from an insulating material, such as a high-density polyethylene, the wildlife guard can be installed on energized electrical equipment using standard live-line tools, thereby obviating the need to shut down the electrical power. The guard includes inner protrusions to fit below the topmost skirt of an insulator bushing, outer protrusions to be grabbed by a live-line tool, and a lengthwise slot through which a conductor is forced during installation.
Claims8
A wildlife guard for covering energized electrical conductors where they emerge from insulator bushings comprising:
- a hollow shell of electrically insulating material having
- a first opening at one end of said shell to accommodate an electrical conductor;
- a second opening at the other end of said shell to accommodate an electrical insulator bushing;
- a longitudinal slot, connecting said first and second openings, through which an electrical conductor can be forced;
- a plurality of inward protrusions to fit under the skirt of an insulator bushing;
- and
- a plurality of outward protrusions to be grabbed by a standard live-line tool during installation or removal.
