BLF-77
BLF-77 tape is a fire-retardant arc proofing tape designed to protect all types of electrical cables. Its unique formulation allows the manufacture of an unsupported elastomer that expands to provide a thick char buildup. This insulating shield protects the cables and accessories from fault arc generated heat and flames. All adjacent wrapped cables and accessories are protected when exposed to fault arcs until limiting devices can interrupt the faulted circuit. Because BLF-77 tape is unsupported, it is extremely conformable. Installers can wrap cables and irregularly-shaped accessories easier and more rapidly. This exceptional conformability enables better product control while wrapping, and more uniform coverage. Also, the tape’s thin cross sections greatly reduce overall weight compared to other methods while providing equal or better arc protection times. Cable heat is dissipated more rapidly than with other forms of thick arc protection. One-half lap wrap provides adequate protection for most installations. However, additional wraps can be applied if conditions warrant without requiring a reduction in conductor loads.
