Cables and electronic harnesses are often used in different environments. Their outer packaging materials provide additional insulation to prevent wear, chemicals, electromagnetic interference, fluids, heat, moisture, and other adverse factors. Depending on the color, the material And size and other factors, can provide a variety of wiring harness protection. This article mainly introduces five kinds of outer packaging materials commonly used for cables and electronic wiring harnesses.


Cable electronic harness
1. Heat shrinkable tube
The heat-shrinkable tube is tightly wound around the wire to smooth the rough surface and provide thermal and electrical insulation. The adhesive-backed tube provides a strong seal to prevent moisture and chemicals from corroding the wiring harness components. A hot air gun is required, which increases production. Time may also be difficult to apply to the entire seat belt.

2. Casing
The sleeve is expandable or packable. The sleeve is easy to install and highly flexible, enabling fast and easy wire bundling. Woven polyethylene sleeves are very popular because they are durable and light-weight, even at low temperatures. The direction maintains complete flexibility, so that the cable assembly and the wire harness can be bent repeatedly without damage.

3. Spiral
The spiral-wound tube allows cables and electronic harnesses to enter and leave the outer packaging material at multiple points. It also offers a variety of color options for easy identification, for example, orange is commonly used in high-voltage applications.

4. Split loom tube
Split loom tubes are generally cut down from the side to facilitate the insertion of cables and electronic harnesses. The cut is closed after installation. No heat shrinkage or dispensing ends are required, thereby reducing production time. Plastic tubes are usually made of polyamide, polyethylene or Made of polypropylene, however, handling wiring without compression can be cumbersome.

5. Tape
The single-coated pressure-sensitive adhesive tape can provide various backing materials and pressure-sensitive adhesives. PVC is the most commonly used tape material, but other materials can also be used, including fabric, felt, foam and aluminum foil. In addition, the tape is also the smallest The flexibility of the harness is reduced.

After reading the above, I believe everyone should understand the five kinds of outer packaging materials commonly used in cables and electronic harnesses.
