Fire Retardant &
Arc Proofing
You can plan ahead for the best outcome in fire and arcing scenarios. Protect your low- and
medium voltage cables and accessories with 3M’s arc proofing and fire retarding tapes. When
the heat rises, the tape expands putting a thick layer of char between the flames and your cable
to help minimize potential damage.
Scotch® Fire
Retardant Electric
Arc Proofing Tape 77
Cables During and After the
Consolidated Edison Flame Test
Applications
• Protect cables from electric
arcs and fires
• Use on energy cables
running in close proximity to
other energy cables, such as:
Swells with
exposure to heat
Light color makes fire
damage easy to identify
Insurance for your cables.
- Cables in substations,
manholes, and vaults
- Critical feeder cables and
nearby branch circuits
- Energy cables in buildings
that cannot afford to
lose power, (e.g. hospitals,
military bases, server
farms, etc.)
- Energy cables in cable
trays
