3M Scotch Electrical Tapes include Scotch 77 fire proofing and arc proofing tape which is a 0.762mm thick tape designed to protect all types of electrical cables.

3M Scotch 77 unique formulation allows the manufacture of an unsupported elastomer that expands in fire to provide a thick char build-up between the flame and cable.

This insulating firewall acts as a heat shield and flame barrier fire proofing and protecting cables, joints and electrical equipment.

3M Scotch 77 Tape - Arc Proofing

Scotch 77 Tape is an arc and fireproofing tape designed to protect all types of LV-HV electrical cables.

The tapes unique formulation allows the manufacture of an unsupported elastomer that expands in fire to provide a thick char build-up between the flame and cable.

This insulating firewall acts as a heat shield and flame barrier, thus protecting the cables and accessories.

All adjacent wrapped cables and accessories are protected when exposed to fault arcs until limiting devices can interrupt the faulted circuit.

Scotch 77 Tape is unsupported and 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 3M Scotch 77 tape’s thin cross sections greatly reduce overall weight compared to other methods while providing equal or better fire and arc protection times.

Cable heat is also dissipated more rapidly than with other forms of thick fire protection, and, therefore, does not de-rate the cable.

One-half lap wrap of 3M Scotch 77 tape provides adequate protection for most installations. However, additional wraps can be applied if conditions warrant without requiring a reduction in conductor loads.
