3M SCOTCH SUPER 33 TAPE – Installation Techniques
- Scotch 33 Tape should be applied in half-lapped layers with sufficient tension to produce a uniform wind (for most applications this tension will reduce the tape’s width to approximately 5/8 of its original width)
- On pigtail splices and joints, the 3M tape shall be wrapped beyond the end of the wires and then folded back, leaving a protective cushion to resist cut-through
- Wrap tape up-hill, taping from a smaller diameter surface to a larger diameter surface
- Apply 3M Scotch 33 tape with no tension on the last wrap to prevent flagging
