|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.
