Knowing the intended use will dictate how much coverage is required, how many layers are required and how precise the installation technique needs to be. Is the material an adhesive-backed, elastic polymer film, a woven fabric or a metal foil? Is it intended to loosely hold a group of wires together so they all follow the same general direction or is it intended to constrict the wiring into the smallest possible bundle diameter and/or provide a secondary performance characteristic? There are specific tape types which are designed to provide additional performance characteristics to cables such as adding abrasion protection, improving dielectric insulation, providing thermal protection, providing EMI shielding or a combination of these. You need to define what type of tape is being used and what the purpose of the tape wrap is. To maximize harness assembly efficiency, long run sections of a cable harness should be jacketed using a wrap-around, zip-on jacket material with tape wrap areas kept to a minimum. Generally, tape wrapping should be limited to short run lengths, cable branch intersections and cable branch legs. Furthermore, tape wrapping is a “craft sensitive” process and the finished installation can vary from installer to installer. Although the tape materials are extremely versatile and appear inexpensive at the buyer level, the finished assembly cost will generally be high because tape wrapping is a very labor-intensive process.
Tape users should be aware that a tape wrap jacketing installation is a highly inefficient and costly harnessing solution. All procedures described herein have been found to provide good mechanical and electrical performance, however, The Zippertubing® Company cannot guarantee end performance results. These instructions are provided as an “idea guide” rather than a rigid requirements document. In-house engineering requirements should always be consulted prior to making any production installation.
The methods described are typical of industry installations and may or may not apply to customer-specific installation requirements. It applies to all tape materials which can be helically wound around a wire and cable bundle. This document describes generic methods for applying insulating, thermal or EMI tape materials.
