Insulating SheetMedium Voltage Insulating barriers. BCIC preformed covers provide connections for insulators, bushings and busbars. Customized covers can be made simply and economically by vacuum forming non-shrinkable sheet material. Installation is very simple often with no need to disconnect busbars. BCIC covers are held in place with UV-stabilized plastic nuts and bolts, rivets or tie-wraps, and can be easily removed for maintenance, or else sealed with Raychem sealing mastic. Suitable for applications up 36 kV. Rigid Red Barrier Board (RRBB) is a non-structural, interphase barrier for switchgear applications. The RRBB board has excellent track resistance, especially following a power-arc. It can be easily fabricated into a shape; produces less nuisance dust and less tooling wear than other boards.
