Insulate and Protect with 3M Electrical Tapes

  • Well-insulated wires and cables can make all the difference in an industrial site as it is critical to the safety of a plant’s operation, especially in extreme temperatures and harsh environments.

    Over the years, 3M has understood the challenges of keeping wires and cables in good shape and innovated continually to keep your operations running smoothly and safely. 3M electrical tapes are designed to provide exceptional insulation in a wide range of temperatures, environmental conditions, and industrial facilities. For every cable or splice you need to insulate, there’s a 3M tape you can rely on.

    Discover which insulation tape to use for your facility’s maintenance program.


Low Voltage Insulation & Splicing

For low voltage applications (<600V), PVC electrical tape is often the ‘go to’ solution for primary insulation. 3M Vinyl Tapes have better stretching ability than other cloth or film tapes, and wrap tightly around cables for highly secure, long-lasting insulation.

When choosing a PVC tape for low-voltage wire and cable splices, consider premium-grade tapes. They have a thicker backing of up to 10 mil for stronger insulation and abrasion resistance. Premium-grade tapes also adhere fast to a wide range of plastics, PVC, copper, and aluminum.

Explore our best professional-grade tapes for low-voltage insulation.

  • Scotch Super 33+ Vinyl Electrical Tape
    • 7 mil thickness
    • Withstands a temperature range of -18–105°C
    • The world’s first vinyl electrical tape
    • Ideal for primary electrical insulation for wire and cable splices up to 600V, and sealing for motor lead connections
  • Scotch Professional Grade Vinyl Electrical Tape Super 88
    • 8.5 mil thickness
    • Withstands a temperature range of -18–105°C
    • Ideal for primary electrical insulation for all bus applications and wire and cable splices up to 600V

Medium Voltage Insulation & Splicing

Medium-voltage cables need splice kits to create a safe, well-insulated connection that won’t break in rugged environments. Use 3M electrical tapes to install the splice kit and quickly rebuild the cable’s insulation, shielding, and cable jacket. Each tape material forms a tough layer that reinforces the splice and protects the integrity of the entire cable.

Bring a splice kit together with these 3M electrical tapes.
