![]() Multiple color choices allow for easy identification. Both polyamide and polyethylene are available. Spiral wrap tubing-allows cables or wires to enter and exit the covering at multiple points.Cable assemblies and wire bundles can be flexed repeatedly without damage. Full flexibility is maintained in any direction, even at low temperatures. Braided polyethylene sleeving is popular, because it’s durable and lightweight. Sleeving-Expandable or wrapable sleeving is easy to install and highly flexible, enabling fast, easy wire bundling.It can also be difficult to apply to an entire harness. Requires a heat gun to apply, which adds to production time. Adhesive-backed tubing provides a strong seal against moisture and chemicals that can corrode harness components. Heat shrink tubing-wraps snugly around wires and smooths out rough surfaces, providing thermal and electrical insulation.Popular cable and wire harness coverings include: For instance, some are easier to install than others. Each option provides different pros and cons that engineers must consider. Wire harness protection is available in multiple configurations based on factors such as color, material and size. “Cost is typically more of a concern for a buyer within the company than for an engineer.” Multiple Options “This is a matter of selecting the right tool for the job,” Brasch points out. “Engineers want to ensure that the being specified into their design will operate ideally in the environment that the wire harness is to be used. “While cost can be a concern for some, we typically see that material performance is the primary concern for engineers,” adds Brasch. “Because of the intense focus on these requirements, cable bundle protection is generally an afterthought. “However, there are still a large number of engineers who don’t address, because the larger focus of wire harness designs are the geometric and electrical requirements,” notes Brasch. “As development of abrasion protection products and materials has become more and more prevalent over the years, some engineers have started to incorporate and specify certain products and materials for use in their wire harness designs,” says Brasch. Manufacturers often learned the hard way that protection is something that’s necessary in most modern wire harnesses. ![]() In the past, wire harness coverings were not usually specified by engineers. ![]()
