3M 700 Electrical Tape 03429NA 3/4 in x 66 ft x 7 mil

Primary insulation up to 600V

This 3M 700 vinyl tape provides primary electrical insulation for wire and cable splices rated up to 600 volts. It suits electricians and maintenance crews who need reliable dielectric protection for indoor or outdoor installations. The black finish identifies phase conductors in standard colour coding.

Fits irregular shapes and harsh environments

High-strength stretch with 200% elongation lets the tape conform tightly around splices, connectors and cable bundles. It adheres across a wide temperature range from 0°C to 80°C, so it stays secure on overhead lines, underground ducts or panel wiring. The 66 ft roll covers multiple jobs without frequent changeovers.

Resists abrasion chemicals and flame

Excellent resistance to abrasion, corrosion, alkalies, acids and weather extends service life in exposed locations. Flame-retardant construction adds a safety margin where cables pass through fire-rated penetrations. The tape also serves for general bundling, harnessing and protective jacketing on high-voltage repairs.
