Introduction to five types of outer insulation materials for wire harnesses and cables


Electronic wire harnesses and cables are widely used in our daily lives. Today, Connector Network mainly talks about the knowledge of their packaging materials. Wire harnesses and cables come in various colors, and their main functions are to provide insulation, protect internal lines, prevent external wear and tear, and pollution and damage caused by some adverse environments. Generally, depending on the color, material, and size, the outer packaging materials of wire harnesses and cables are also different. Let's take a look at the types of materials below.

Generally, depending on the color, material, and size, the outer packaging materials of wire harnesses and cables are also different. Let's take a look at the types of materials below.

Heat-shrink tubing: Heat-shrink tubing tightly wraps around the wires, smoothing rough surfaces, providing thermal and electrical insulation. Adhesive-backed tubing provides a strong seal, preventing moisture and chemicals from corroding the wire harness assembly. A heat gun is required, which increases production time and may be difficult to apply to the entire harness.

Sleeving: Expandable or wrap-around sleeving is easy to install and highly flexible, enabling quick and easy wire bundling. Braided polyethylene sleeving is popular because it is durable and lightweight, maintaining full flexibility in any direction even at low temperatures, allowing cable assemblies and wire harnesses to be repeatedly bent without damage.

Spiral wrap: Spiral wrap allows cables and electronic harnesses to enter and exit the outer packaging material at multiple points. It also offers a variety of color options for easy identification; for example, orange is commonly used for high-voltage applications.

Split loom tubing: Split loom tubing is generally cut open from the side, making it easy to insert cables and electronic harnesses. After installation, the cut closes, eliminating the need for heat shrinking or dispensing end caps, thus reducing production time. Plastic tubing is typically made of polyamide, polyethylene, or polypropylene. However, handling and not compressing the wiring can be cumbersome.

Tape: Single-sided coated pressure-sensitive adhesive tape offers a variety of backing materials and pressure-sensitive adhesives. PVC is the most commonly used tape material, but other materials can also be used, including fabrics, felt, foam, and aluminum foil. In addition, tape minimizes the flexibility of the harness.
