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.

緊緊纏繞膠帶以實現防水密封。橡膠膠帶通常用PVC膠帶包裹。

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。
