Corrugated cable types and sizes which exist

One of the variants of protection is to use wire the corrugated pipe, which not only protects supply cable against mechanical damage, but also increases the wiring resistance to aggressive environmental manifestations environment. In this article I will tell about the main types and sizes of corrugated pipes, as well as they are made of any material.

What is the corrugation

Primarily corrugation is designed to protect the cable from all sorts of mechanical influences, for protection against moisture and high temperatures and the corrosive chemicals. With proper installation and use of special fittings provided excellent protection from moisture.

Basic types and kinds of corrugated pipe

Corrugated pipe varies according to parameters such as:

1. Diameter. The larger the size, the thicker the cable can be placed inside.

2. wall thickness. Corrugated tube with thin walls is easy to bend, but it is deformed by slight pressing, and with thicker walls is not so plastic, but reliably protects the cable from the kinked.

3. applicable material for the manufacture of. For the production is used as a metal plate, and various kinds of plastic. Just depends on the material, which is better to use some form of corrugations.

4. Color palette products.

5. Strength characteristics.

Let us now for each of the parameters will talk in more detail.

The diameter and wall thickness of the corrugated pipe

As mentioned above, the diameter of the bellows depends on how thick cable can be placed in it. It is worth mentioning that according to the SAE 7th item edition 2.1.61. "The occupancy rate of the corrugations must not exceed 35% of the cross-section of the light." Therefore, in order to understand what you need to buy a corrugation, it is necessary to measure the diameter wire and then from below the table to select the corrugated pipe to the desired internal diameter corresponds to the occupancy requirements PUE:

In this case the wall thickness of the corrugations may vary quite widely from 5 to 15 mm.

Used material and color versions

So, let's talk about the material and color of the product. These two items also go together, because there is no manufacturer that would just dyed your product (with very few exceptions). So even just by looking at the color, you can immediately see what material is manufactured.

Thus, gray corrugations means that it is made of polyvinylchloride (PVC), which has the following features:

Black or orange color indicates that the product is made of high density polyethylene (HDPE), and it has the following features:

Blue color indicates the use of self-extinguishing the polypropylene (PP). It has the following features:

Metal hoses do not have any color and features are as follows: increased mechanical strength.

strength characteristics

Thus, resistance to stress corrugated pipe characterized as follows:

1. Lungs. Can withstand loads of up to 320 Newton 5 square centimeters. They are the easiest and flexible.

2. average. Can withstand loads of up to 750 Newton on the same 5 square centimeters. Such corrugated tubes are mainly placed in Stroebe.

3. severe. Keep the load to 1250 Newton for 5 cm2. Hard to use when laying the screed.

4. Superheavy with a reinforcement. Keep the load to 4000 Newton 5 square centimeters. Intended for laying in the ground, as well as for suspending the supports with mounting street.

That's all I wanted to tell you about the types and characteristics of the corrugated pipe. Thanks for attention.
