Medium 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.

  • Make in India
  • TE
  • BCIC - Insulating covers designed to prevent animal caused outages on MV distribution lines, substation connections and bushings
  • Rugged, track resistant, UV resistant polymer ensures long-term performance even in the most extreme environmental conditions
  • Made from Raychem Red HV outdoor material
  • Flexible to fit many configurations and insulator sizes
  • RRBB - Excellent tracking resistant properties provides longevity not found in typical polymers
  • UV properties of barrier boards are suitable for outdoor applications
  • Extremely durable barrier boards are damage resistant from solvents, mechanical impact and general wear and tear
  • Innovative cross-linking polymer withstands power-arcs without compromising its physical shape. The high temperature resistant material can be wiped clean after power-arc events resulting in no visible effects of surface damages.
