Electrical Tapes
3M has been developing and manufacturing high performance, easy handling electrical tapes since the 1940s. The 3M Electrical Tapes range includes
tapes for low and medium voltage insulating, colour coding, moisture sealing, padding, shaping, protective jacketing, bundling, and harnessing.
Additionally, 3M manufactures a variety of tapes for technical applications; semi-conducting tape to reconstruct a medium voltage cable, track resistant
tapes for terminations, and fire retardant electric arc proofing tapes to protect cables from arcs and fires from nearby cable failures.
Taping Tips
To ensure the safest, most reliable use of PVC Electrical Tapes, always:
• Apply tape with enough stretch to conform to the objects you’re wrapping. Be
sure to let the last 50 mm relax before tabbing it down to prevent unwinding
(sometimes called “flagging”).
• Wrap an irregular mechanical connector, such as a split bolt, with rubber or
mastic tape to pad sharp edges, before overwrapping with vinyl electrical tape.
• Wrap tapered shapes “uphill” – that is, from the smallest to the largest point. This
way you always secure the previous layer.
• Always use scissors or a knife to cut tape. If you must tear it by hand, then keep
fingers close together when tearing tape. The farther apart they are, the more the
tape will stretch before it tears.
• Use the right tape for the right conditions. Vinyl tapes are rated for cold weather
application in two classes: 0°C and -18°C. Tapes formulated for high temperature
environments are typically rated 80°C or 105°C. Only professional grade tapes
should be used on cables rated for less than 0°C and higher than 80°C.
Type of Tape
Number of Layers/Application Instructions
Vinyl Electrical Tapes -
Jacketing and Mechanical Protection Always use a minimum of two half-lapped layers. The last layer should be
wrapped in a more relaxed manner - let the last wrap relax to prevent the
layer from flagging.
Rubber Tapes -
Electrical Insulation, Mechanical Padding, Water
Sealing and Shaping
Wrap tape tightly to achieve the watertight seal. Rubber tapes are typically
overwrapped with vinyl tape (refer image above).
High Voltage Tapes -
Insulating and Semi-conductive Layers
Apply outside of roll to the cable, in highly stretched half-lapped layers.
Never use a semi-conductive tape as an insulation.
Mastic Compounds -
Insulating, Mechanical Padding, Moisture
Sealing and Shaping
Overwrapping with vinyl prevents mastic flow and helps to create a
watertight seal. Do not apply excessive amount of mastic to prevent oozing.
