3M 7100004701 | 77B-3X20FT Scotch 20' OAL x 3.000" Width x 30.0 mil Thickness Electrical Tape

Scotch tape 77 is a 30 mil thick, premium grade, flame retardant, electric arc proofing tape. This tape is 600V rated and is suitable to protect most types of electrical cables when exposed to potential failures in an adjacent cable. It is designed with a flexible unsupported elastomer, which makes it easy to apply and easy to remove for cable inspection.

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 "es until limiting devices can interrupt the faulted circuit.

• Thin cross section for reduced weight
• Adequate protection with one half-lap wrap
• Possibility to apply additional wraps if needed

Wrap Scotch Tape 77 in half-lapped layers. The tape should be stretched slightly to obtain a snug, wrinkle-free wrap which conforms to the cable. Overlap the last 6 "es of protected cable when starting a new roll of tape.

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.

• 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"es)
• Conforms Easily with Minimal Effort: 30 mls thickness offers virtually wrinkle-free wrapping
• Reusable: Can be removed and reused
• Compliance: RoHS compliant
• Stability: 5-year shelf life (from date of manufacture)
