What is a cable shelf

The system for the installation of power lines and wires contains details of varying complexity that are used to distribute energy carriers and simplify the fixing process. A cable shelf is just one of these parts, created for the convenience and rationality of service, a presentable appearance.

It is made mainly of profiles with a coating of zinc to protect against corrosion. Perforated material is used to increase the transferred loads. Cable shelf Must comply with state standards, have the manufacturer's data on the surfaces of the elements and be created taking into account the technological operating conditions.

What does it consist of?

The cable shelf is assembled only with additional elements, due to which a solid support structure is formed, since it can not withstand the full load of electric wires. These elements include the following:

• Base for shelves;
• Hardware;
• Shelves for wires;
• Racks for fixing to the ceiling.

In addition to the main parts, additional parts are used, which are intended for separating or joining cables and energy carriers, for example fasteners, carriages, nuts, broaching boxes. So it becomes clear how many key and additional parts are required to bring the electrical cable to the end users. The protection of the wiring against overheating and simplified access for repair are formed in this way. Shelves are used in those situations when it is impractical or impossible at all to install wires and lines with a hidden method. So they are the bearing structures that form the location of the power path.

Characteristics

The standard cable shelf, whose weight can reach up to 0.6-0.8 kg, has a U-shape. There are different types of products, differing among themselves such characteristics as permissible loads, compliance with climatic conditions, structural features, size. The profile extends somewhat towards the center, thus providing additional density. The cable shelf with the rack, which accounts for the weight of the structure, has the most stable fastening, and with its dismantling one person can not cope. Due to this, it is actively used in places with seismic activity. The house will receive electricity even with a noticeable earthquake. Each element has a galvanized coating and is suitable for subsequent painting. When choosing shelves, you need to build on the operating conditions, features of the room and other characteristics. Today in the market you can find a wide variety of devices of Russian manufacturers, which differ in acceptable cost and high quality.
