3M 2520 Varnished Cambric Tape 1 in x 108 ft 8 mil Yellow

Insulating Electrical Tape for High-Temperature

This 3M varnished cambric tape provides abrasion-resistant insulation for electrical conductors. The rubber adhesive bonds to cotton cloth backing rated for continuous operation up to 220 degrees Fahrenheit. It suits electricians and maintenance crews wrapping motor leads, transformer coils or bus bars where heat and mechanical wear are concerns.

Thermals Noise and Power Draw in Normal Use

The tape withstands maximum operating temperatures of 220 degrees Fahrenheit without degrading its insulating properties. As a passive wrapping material it generates no noise and draws no power during application or service. The 8 mil thickness maintains dielectric strength while resisting abrasion from vibration or movement.

Continuous Roll Format Simplifies Long Runs

A single 108 foot roll eliminates splices when insulating extended conductor lengths. The one inch width covers standard wire gauges and small bus bars in fewer passes. Yellow colour coding allows quick visual identification of phased circuits or high-temperature zones during inspection.
