Protect YourValuable Assets
The cost of repairing adjacent cables and other assets from
fire damage is expensive. The Scotch®
Fire-Retardant Electric
Arc Proofing Tape 77 Series provides protection for adjacent
electrical circuits when a cable or splice fault is damaged by fire.
The intumescent quality of the tape makes it expand with heat,
providing a barrier for adjacent cables until limiting devices can
interrupt the failed current.
