End Sealing Kit for Extensible RMU / GIS Bushing

End Sealing Kit for RMU extensible / GIS Bushing is used to seal and insulate the ends of Bushings & also protect it from ingress of water / moisture. The caps used in End Sealing Kits are manufactured from high quality Cross-linked Non-tracking Polyolefin material.
Compatible with all types of Bushings.
The caps need to be removed from the Bushings for new connections.

Screened Sealing Kit with Ground

Touch Proof Protective Cap is designed to electrically insulated and mechanically seal busing interfaces. The cap can be sued for permanent and temporary insulation on bushing, junctions.

Screened End cap is an accessory device designed to electrically insulate and mechanically seal bushings. When installed on the bushings and the drain wire is attached to ground, the Screened End cap provides a fully shielded, submersible insulating cover for energized bushings. The cap can be used for permanent or temporary installation on bushings, junctions, or feedthru devices.
