For those who often purchase components, they must have encountered the procurement items of electronic wiring harness and cable products, then do you know what are the types of outer packaging materials for electronic wiring harness and cables? If you don't know anything about layer packaging materials, you can take a look at this article.
Cables and electronic wiring harnesses are often used in different environmental scenarios. Their outer packaging materials provide an additional insulating layer to prevent abrasion, chemicals, electromagnetic interference, fluids, heat, moisture and other adverse factors. According to the color, wire harness protection is available in a variety of configurations depending on factors such as material and size. Let's take a detailed look at the types of outer packaging materials for electronic wiring harnesses and cables.
1. Heat shrink tubing
Heat-shrinkable tube tightly wraps the wires so that the rough surface becomes smooth, providing thermal and electrical insulation. And the adhesive-backed tube provides a strong seal to prevent moisture and chemicals from corroding the wiring harness assembly. But it requires the use of a heat gun, which increases production time and may also be difficult to apply to the entire harness.
2. Casing
Sleeves expandable or packable sleeving is easy to install and highly flexible for quick and easy wire bundling. Braided polyethylene sleeving is popular because it is durable and lightweight, and can be used in any environment, even at low temperatures. The orientation remains completely flexible, allowing cable assemblies and wire bundles to be bent repeatedly without damage.
3. Spiral wound tube
Spiral wound tube allows cables and electrical harnesses to enter and exit the outer packaging material at multiple points and is also available in a variety of color options for easy identification, eg. orange is often used for high voltage applications.
4. Split loom tube
Split-type loom tubes are generally cut from the side downwards for easy insertion into cables and electronic wiring harnesses. After installation, the cuts are closed and there is no need for heat-shrinking or dispensing ends, thereby reducing production time. Plastic tubes are usually made of polyamide, polyethylene or polypropylene. However, if we only handle but not compress wires would be cumbersome.
5. Tape
Tapes, single-sided coated, pressure sensitive tapes are available in a variety of backing materials and pressure sensitive adhesives. PVC is the most commonly used tape material, but other materials are also available including cloth, felt, foam and aluminum foil. In addition, the tape minimizes the flexibility of the wiring harness.
