These covers are made of high-dielectric polyethylene. The wax-like surface provides a natural self-cleaning action and resists theeffects of greases and other contaminants. The bright-orange color gives a visible warning to those who are working close to the equipment. Chance conductor covers are designed to help protect the lineman while working close to energized conductors. They are rated phase-to-phase for voltages through 46kV and can be easily installed with a Grip-All clampstick. The conductor cover clips on and covers conductors up to 2 inches in diameter. A positive air gap is maintained by a special hanger system inside the cover. The conductor is locked in the hanger by a swinging latch that can be opened and closed with a hot stick.
