| Wrapping Tips |
| Type of Tape |
Number of Layers/Application Instructions |
| Vinyl Electrical - 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 water tight seal. Rubber tapes are typically overwrapped with vinyl tape. |
| 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 |
Mastic compounds are to be overwrapped with vinyl tapes to initiate flow and watertight seal. Do not apply excessive amount of mastic to prevent oozing. |
