DF77 Fire-Retardant and Electric Arc Proofing Tape

DF 77 Tape is a fire retardant arc proofing tape designed to protect all types of electrical cables. It makes unsupported elastomer that expands to provide a thick char buildup. 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.

Description
Feature
Flexible unsupported elastomer—clean, easy to apply, eliminates cuts and contusions of hands.
Conformability provides wrinkle-free wrapping and complete coverage with minimum effort.
Self-extinguishing
Thin (30 mils) thickness, cable heat to be slow dissipated..
Will last and maintain its arc proofing properties for the life of the cable.
Water, salt water, acids, sewage and ultraviolet light resistant.
Can be removed and reused.
 
Application
To arc proof high-energy power cables where exposed to failures of other high-energy cables.
To arc proof control cable when high energy power cables are present
Provide additional electrical insulation, thus reducing possibilities of transferred arcs.
