Scotch Fire-Retardant Electric Arc Proofing Tape 77 is a 30-mil thick, premium grade, flame-retardant, electric arc proofing tape used to help protect most types of electrical cables from fault arc-generated heat and flames of nearby cable failures. These halogen-containing elastomeric tapes are formulated to generate a thick, insulating charred buildup when exposed to high temperatures. The insulating charred buildup protects wrapped cables and cable accessories from the fault arc-generated heat and flames of cable failures within approximately 20 inches until limiting devices can interrupt the faulted circuit. The tape’s thin cross section reduces the overall weight compared to other methods while providing 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. Since the Scotch Tape 77 Series is not adhesive coated, it must be held in place after wrapping with bands of Scotch Glass Cloth Electrical Tape 69. One of the most effective and economical ways to hold either of these tapes in place is by banding (2 complete wraps) the first and last applied wrap. Application/Industry: Mining, Commercial Construction, Solar, Industrial Construction, Wind Power, Maintenance and Repair Operations, Utility, Residential Construction
- INTUMESCENT ELASTOMER BACKING: Flexible unsupported elastomer makes it easy to apply and remove for cable inspection
- IDEAL FOR OVER-EXPOSED ELECTRICAL CABLES: To arc proof high-energy power cables exposed to nearby arc-fault high-energy cables (within 20 inches)
- CONFORMS EASILY WITH MINIMAL EFFORT: 30 mls thickness offers virtually wrinkle-free wrapping
- REUSABLE: Can be removed and reused
- COMPLIANCE: UL Listed and RoHS 2011/65/EU Compliant
- STABILITY: 5-year shelf life (from date of manufacture)
- For protecting most types of electrical cables when exposed to potential failures in an adjacent cable
