ABSTRACT:
The invention relates to a shield which prevents squirrels or other animals from causing faults in power distribution substations. Switch and bus insulators are primary points of contact when a small animal crawls from a grounded, supporting structure across an insulator to an energized conductor. The present invention provides for a barrier on switch and bus insulators which prevents animals from coming into contact with a grounded structure and an energized conductor simultaneously, thus eliminating a ground path from the energized conductor through the animal to the grounded structure.
