250A, 24kV Insulated Protective Cap

The CEE JYM-24/250 insulated protective cap is an accessory device designed to electrically insulated andmechanically seal deadbreak bushing interfaces. It can also protect the de-energizedinterface from dust and damp. This insulated protective cap can be used for permanent or temporary installation on bushings, 250A bushing. If there is a reservedinterface in the bushings, the insulated protective cap must be used. The cap is molded of highquality EPDM insulation. When mated toa deadbreak product and the drain wire is attached toground, the insulating protective cap provides a fully shielded insulatingcover for energized deadbreak bushings.
