What Is a Wiring Protector?
Wiring protectors are products that protect various types of wiring from force and electrical action.
There is a wide range of products, many of which are tube-shaped, with snap-button closures or slits.
Among them, corrugated tubes are often used because they are strong, soft, easily bendable, and easy to remove.
Each tube is available not only for indoor use, but also for heat-resistant or cold-resistant outdoor use, depending on the material.
Uses of Wiring Protective Materials
Shape-memory braided tubing is lightweight and flexible, so it can be used as a wiring protector to flexibly bundle wires, and is used to bundle airplane wiring, concerts, and theater sound and lighting equipment.
In addition, corrugated tubing in the form of bellows with slits is widely used in automobiles, construction machinery, agricultural machinery, home appliances, and housing, especially for protecting wiring harnesses.
Grommets are used to protect wiring from damage caused by holes in panels such as wiring pullouts.
Principle of Wiring Protective Materials
Each wiring protector basically protects the wiring by covering it with a tube or similar material. Protective materials with slits are more easily inserted into the wiring. The part number is selected by comparing the inner diameter of the wire that fits the protective material with the natural inner diameter of the tube. In addition, the use of the tube will vary depending on the material of the tube. Descriptions of materials are provided below.
1. Polypropylene
Insulating and does not conduct electricity. It is often used for standard tubing because of its flexibility and resistance to cracking. It is also inexpensive and available in a wide range of sizes and colors.
2. Nylon
This material can withstand temperatures as high as 100°C and is insulating. It tends to be slightly harder and more expensive than polypropylene. It has excellent weather resistance and is preferred for outdoor use.
3. Nylon (containing rodent repellent)
This product can reduce damage caused by rodent bites when used indoors or outdoors. It is designed to cause irritation and pungency when gnawed by rats, preventing wire breakage.
4.Chlorotrifluoroethylene
It is elastic, slippery, and heat resistant up to about 150℃. It is however, expensive.
Other products with self-extinguishing properties and heat resistance up to about 180°C, such as silicon braided and glass braided tubes, are also available.
