The invention relates to a shield (118, 124) 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 (102) across an insulator (108, 112) to an energized conductor (104, 106). The present invention provides for a barrier (118, 124) on switch and bus insulators (108, 112) which prevents animals from coming into contact with a grounded structure (102) and an energized conductor (104, 106) simultaneously, thus eliminating a ground path from the energized conductor (104, 106) through the animal to the grounded structure (102).
