Wire loom tape, also known as wire harness tape, plays an important role in protecting the wires in the wire harness for long-term use. Have you ever found that when using wire harness products, the wire harness gets damaged after a short period of use? And as a result, they have borne a lot of unnecessary maintenance costs? In the following article, we will take you to understand the reasons why wire loom tape can still maintain the durability of the wire harness under extreme environmental conditions.

 

The definition of wire harness tape

Wire Harness Tape

Wire loom tape, also known as harness tape or wire loom harness tape, is not the transparent tape for sealing boxes that can be seen everywhere in daily life. Instead, it is a kind of tape specifically used to protect and fix the wires in wire harnesses.

This type of tape is widely used in various industries, such as home appliance wiring harnesses, industrial wiring harnesses, electronic product wiring harnesses, etc. It is one of the important tools for wiring professionals to carry out wiring.

The main functions of wire loom harness tape

 

Protection:The main functions of wire loom harness tape for wire harnesses

The functions of Wire loom tape, in addition to the main protection, also include fixed binding, insulation, identification, noise reduction, etc.

 

Dust-proof and moisture-proof measures should be taken to prevent the wires from being affected by adverse environments.

 

 

It can withstand extreme temperatures. Under high or low temperature conditions, it can still maintain the stable operation of the wiring harness and is not easy to melt the casing.

 

 

Corrosion-resistant, it can resist the corrosion of chemical substances such as gasoline and engine oil.

 

 

Wear-resistant. For example, automotive wire loom tape can reduce the friction between the wiring harness and the components of the vehicle body during operation and prevent the insulation layer of the wires from being damaged.

Insulation

Insulation

cable harness tape enhances the safety of the wire harness, which is equivalent to forming an insulating layer on the outside.

Noise reduction

The Wire loom tape is on the outer layer of the wire harness, which can reduce the frictional noise generated by the wire harness as the vehicle starts and runs.

Fixation and bundling

Messy wires can be neatly bundled together to form a single wiring harness. For example, inside a car, the application of car wiring loom tape helps to quickly wire the harness.

Marking

When cloth wiring harness tape is wound on the outside of the wiring harness, it usually has words and colors, making it easy to distinguish various different wiring harnesses.

The features of cable harness tape

 

  • Non-sticky winding design

This is the biggest difference between cloth wire loom tape and ordinary tape. Wire loom tape does not stick to the wires. It is only sticky to itself. When the wire harness tape is wound around the wire harness, each layer on the outside will stick to the next layer and will not stick to the wire harness. The advantage of this is that it is convenient for later unwinding, modification and maintenance, and no residual glue will be left on the wiring harness after unwinding.

 

  • Used materials of Wire loom tape generally 

1.PVC(polyvinyl chloride): This is the most commonly used material, featuring excellent flame retardancy, high wear resistance and good flexibility.

2.Non-woven fabric: It has heat insulation effect and excellent sound absorption.

3.Cloth: The most common type is fiber cloth coated with PVC. Its touch is similar to that of electrical tape, but it has stronger performance, high heat resistance and tear resistance.

4.Felt: Generally used for noise reduction and vibration damping.

Summary

Wire loom tape is an indispensable material in the manufacturing and post-production protection of wire harnesses. By self-bonding, it provides a strong and wear-resistant "protective cover" for the wire harness, ensuring its safety, reliability and long-term durability in complex working environments.
