Abstract: A dielectric cover for an insulator, supporting a high voltage conductor in an electrical distribution system, has holes for receiving retaining pins. The retaining pins are used to secure the cover over the insulator and conductor. Arched fenders, which may be circular or have a bottom opening, extend out from the cover and overlie the holes and ends of the pins. The fenders prevent birds roosting on the pin, increase the dielectric surface length between the top of the cover and the electrical conductor above the pins, and protect the pins from contamination issues which would reduce the dielectric properties of the pins. Contamination issues include birds defecating on the pins, which can create a conductive path between the bird and the inside of the cover, and atmospheric moisture such as rain, snow, and ice on the pins. Thus, wildlife is protected from electrocution.
