3M 7000132814 Varnished Cambric Electrical Tape 2x36yd

Product Description

The 3M 7000132814 is a varnished cambric electrical insulating tape designed for use in motor, transformer, and coil winding applications where reliable dielectric protection is required. Constructed from straight-cut woven cotton cambric fabric, the tape is oil primed and finished with a high-grade yellow electrical insulating varnish. It measures 2 inches wide by 36 yards in length per roll. The flexible construction and smooth varnish surface make it well suited for wrapping irregular or contoured components without cracking or delaminating. Electricians and motor rewinding technicians are the primary installers of this tape in both shop and field environments.

This tape is used in residential and commercial electrical applications where a combination of flexibility, moisture resistance, and electrical insulation is required. Typical uses include slot insulation on motor windings, transformer coil wrapping, and general dielectric barrier work. The moisture-resistant varnish coating helps protect windings and insulated components from environmental contamination during normal service conditions.

Key Features

• Straight-cut woven cotton cambric fabric base for consistent tensile strength
• Oil-primed fabric coated with high-grade yellow electrical insulating varnish
• Electrically insulating and moisture resistant construction
• Flexible build conforms to contoured or irregular surfaces without cracking
• Smooth finish supports clean layering in coil and winding applications
• 2 inches wide by 36 yards per roll for extended coverage per unit

Compatibility

Designed as an OEM-style electrical insulating tape suitable for motor rewinding, transformer wrapping, and general dielectric insulation tasks in residential and commercial electrical work.

Installation Notes

Installation should be performed by a licensed electrician or qualified motor rewinding technician. De-energize and lock out all equipment before applying tape to any winding or electrical component, following applicable NFPA 70 lockout/tagout procedures. Apply with consistent tension to avoid gaps or air pockets between layers. Do not stretch the tape beyond its natural flexibility, as distortion of the cambric weave may reduce dielectric performance.
