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.
- Semi-conducting tape to reconstruct a medium voltage cable
- Track resistant tapes for terminations
- Fire retardant electric arc proofing tapes to protect cables from arcs and fires from nearby cable failures
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 50mm 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 it with vinyl electrical tape.
Wrap tapered shapes “uphill” — that is, from the smallest to the largest point. This way you always secure the
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
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.
|Type of Tape||Number of Layers/Application Instructions|
|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 over wrapped with vinyl tape.
|High Voltage Tapes||Insulating and Semi-conductive
|Apply outside of roll to the cable, in highly stretched
halflapped layers. Never use a semi-conductive tape as an
|Mastic Compounds||Insulating, Mechanical Padding,
Moisture Sealing and Shaping
|Over wrapping with vinyl prevents mastic ﬂow and helps
to create a watertight seal. Do not apply excessive
amount of mastic to prevent oozing.
