Cable corrugation: what is it and how to choose it?

At the moment, there are a number of ways to protect electrical and other types of wires from mechanical damage, but the cheapest and most affordable option is cable routing in corrugation. This is completely unsurprising. The corrugation for the cable is flexible, which allows it to be attached to any part of the object, even inaccessible. This material is fireproof. If the wire ignites, the corrugation is compressed. This stops the combustion due to the lack of oxygen.

The corrugation for the cable can be made in different modifications, which is worth exploring in detail. Knowing what they can be is very important. Even if you are not going to install yourself, this will allow you to monitor the actions of those who will do it.

The corrugation for a cable happens of such types:

1. Light flexible hose with a low degree of mechanical stability. This kind of corrugation is usually used for external and internal laying. A distinctive feature of this device is the rapid damage due to heavy and sharp loads, so the cable will not be fully protected. This type is ideal for use under plasterboard structures, over stretch ceilings, and also where it will not be subjected to direct pressure.

2. A heavy version usually has medium strength. Such cable corrugations are intended for installation in plaster, concrete or earth.

3. Superheavy view is excellent for laying underground networks or in places where there is a need for increased safety. These include schools, hospitals or other public institutions. This can be a metal corrugation for the cable, capable of withstanding significant loads.

With what kinds exist, everything is clear. It is worth noting the need to pay attention to a number of points before buying. Before ordering corrugation, it is necessary to clarify the conditions of its operation. With mechanical loads, everything is clear, so you need to know how she will behave under the influence of moisture and ultraviolet. You also need to make sure that the fastening clips are of the same quality. They have to withstand the planned load. Very often the corrugated is sold defective, while inside it there is no steel cable, and in fact it is designed for pulling the cable.

Usually corrugated pipes are a product of polymer production, which consists of two layers: internal and external. The latter is low-pressure corrugated polyethylene, which is designed to protect the first. Inside the corrugation is absolutely smooth. It is made of high-density polyethylene. Such smoothness is needed to ensure that the product inside does not get scraped and does not go out of order too quickly. The diameter of the corrugation for the cable can be arbitrary.

Today this type of protection is used all over the world, as it is environmentally friendly, safe and affordable. In case of failure it is easier to replace the corrugation than to lay new cables.
