At the moment, there are a number of ways to protect electrical and other types of wires from mechanical damage, but the most inexpensive and affordable option is to lay the cables in the corrugation. This is completely unsurprising. The corrugation for the cable is flexible, which allows you to attach it to any part of the object, even inaccessible. This material is fireproof. If the wire ignites, the corrugation seems to be compressed. This stops combustion due to the lack of oxygen.
Corrugation for the cable can be made in different versions, which is worth exploring in detail. Knowing what they can be is very important. Even if you are not going to carry out the installation yourself, this will allow you to control the actions of those who will do it.
Corrugation for cable is of the following types:
1. Lightweight flexible sleeve having a low degree of mechanical stability. This type of corrugation is usually used for outdoor and indoor installation. A distinctive feature of this device is its quick damage due to heavy and sharp loads, so the cable will not be completely protected. This type is ideal for use under drywall constructions, over stretch ceilings, and also where direct pressure will not be exerted on it.
2. The heavy version usually has medium strength. Such a corrugation for cable is intended for installation in plaster, concrete or earth.
3. The super-heavy look is perfect for laying underground networks or in places where there is a need for increased security. These include schools, hospitals or other public institutions. It can be a corrugation metal for a cable, capable of withstanding significant loads.
With what species exist, everything is clear. It is worth noting the need to pay attention to a number of points before buying. Before ordering a corrugation, it is necessary to clarify the conditions of its operation. With mechanical loads, everything is clear, so you need to find out how it will behave under the influence of moisture and ultraviolet radiation. Care must also be taken to ensure that the fastening clips are also of appropriate quality. They are required to withstand the planned load. Very often, corrugation is sold defective, while inside it there is no steel cable, and yet it is designed to pull the cable.
Typically, corrugated pipes are a polymer product, which consists of two layers: internal and external. The latter is a low-pressure corrugated polyethylene that is designed to protect the former. Inside the corrugation is absolutely smooth. It is made of high pressure polyethylene. Such smoothness is needed so that the product inside does not fray and does not fail too quickly. The diameter of the corrugation for the cable can be arbitrary.
Today, this type of protection is used around the world, as it is environmentally friendly, safe and affordable. When a failure occurs, it is easier to replace the corrugation than to lay new cables.
