Cable wells are most often objects of the telecommunications canalization or technological channel KT. They are used to pull, connect, branch or install cable reserves (including cable joints). It is worth learning what is most important about them, In the article you will learn what a cable well is, you will learn about the types of cable wells and you will see which cable well to choose.

What is a cable pit?
Cable wells have a very important task, because they provide access to pipes and cables, i.e. important components of cable canalization. Of course, it is necessary not only in the context of network installation, but also future tasks related to maintenance and modernization. Many cable wells also provide more - connecting or branching cable reserves. They consist of several important elements. The base is the body, and apart from it, it is worth mentioning, among others, concrete settling tanks, used to drain water from the well chamber. They also have another, equally important, role, providing space for the installer's legs.
Other parts include well brackets and support tubes to support cables running through the well chamber. We can also see here the throats of cable wells (a characteristic narrowing of the well chamber at the wall) - this is where the openings for the sewage pipes are located. The top of the well consists of a frame and a cover (they function as a manhole to the well).
What types of cable pits are there?
Cable wells are most often divided according to their application. Taking this into account, we have many different types of cable wells to choose from. Main wells (SKM), used for the construction of multi-hole cable canalization, SKR distribution wells, used for branching cable routes or canalization bends, or cable through wells (SK) - perfect for straight sections of canalization, are very popular.
As you already know, the main function of cable pits is to provide access to pipes and cables for installation, maintenance or modernization. An equally important role is that they allow for connecting or branching cable stocks. They differ in many ways, especially when it comes to size, purpose and material.
Optimal cable wells (SKO) are also very popular, as they are very versatile, so they can be used as through, corner and distribution wells. Other types include through main wells (they allow for the construction of many, from 8 to 12 multi-holes), distribution main wells (similarly to the previous case, but not for straight sections, but when there is a need for a branch or a bend in the sewage system) and corner cable wells (as the name suggests - they are used on bends in cable routes).
