3M  2151 Electrical Tape should be applied in successive half-lapped, level-wound layers until desired build-up is reached. To eliminate voids in critical areas, highly elongate the tape. Stretch the tape in these critical areas just short of its breaking point. Doing so will not alter its physical or electrical properties. In less critical areas, less elongation may be used. Normally, 2151 Tape is stretched to Ύ of its original width in these less critical areas. Always attempt to half-lap to produce a uniform build-up. When using 2151 Tape for splicing cables from 35kV to 69kV, always elongate the tape throughout the entire splice.

3M Tape Wrapping Tips

3M 膠帶纏繞技巧

Type of Tape

Number of Layers/Application Instructions

Vinyl Electrical - Jacketing and Mechanical Protection

PVC電氣膠帶 – 外表保護和機構性保護

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.膠帶一半寬度層層搭接 至少使用兩層。最後一層應以更寬鬆的方式纏繞 - 讓最後一段結束纏繞時,以放鬆無張力方式貼上,以防止該段鬆脫。

Rubber Tapes - Electrical Insulation, Mechanical Padding, Water Sealing and Shaping

橡膠膠帶 - 電氣絕緣、機械填充、防水和填充成型

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

高壓膠帶 – 用於絕緣層和半導體層

Apply outside of roll to the cable, in highly stretched half-lapped layers. Never use a semi-conductive tape as an insulation.

將膠帶拉開伸展 以膠帶外側面貼在電纜上 一半寬度層層搭接。勿使用半導體膠帶作為絕緣膠帶。

Mastic Compounds - Insulating, Mechanical Padding, Moisture Sealing and Shaping

膠泥化合物膠帶 - 絕緣、機械填充、防潮密封和成型

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.

膠泥化合物膠帶纏繞好時 應該用PVC膠帶再包裹 使其具有撥水流動性和防水密封性。不要用過量的膠泥以防止滲漏。
