The system for installing power lines and wires contains parts of varying complexity, which are used to distribute energy carriers and simplify the fixing process. The cable shelf is just one of these parts, designed for convenience and rationality of maintenance, presentable appearance.
Produced mainly from profiles coated with zinc to protect against corrosion. The perforated material is applied to increase the transferred loadings. The 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 is it made of?
The cable shelf is assembled only with additional elements, due to which the load-bearing one-piece structure is formed, since it cannot withstand the full load of electrical wires. These items include:
- base for shelves;
- hardware;
- shelves for wires;
- stands for ceiling mounting.
Used, in addition to the main parts,additional parts that are designed to separate or connect cables and energy carriers, for example, fasteners, carriages, nuts, pull boxes. So it becomes clear how many key and additional parts are required to bring the electrical cable to the end users. The wiring protection against overheating and simplified access for repairs are formed in a similar way. Shelves are used in situations where it is impractical or impossible to install wires and lines in a hidden way. So they are load-bearing structures that form the location of the power track.
Features
A standard cable shelf, the weight of which can reach up to 0.6-0.8 kg, has a U-shape. There are various types of products that differ from each other in such characteristics as permissible loads, compliance with climate conditions, design features, size. The profile expands slightly towards the center, thus providing additional density. The cable shelf with a rack, which bears the weight of the structure, has the most durable fastening, and one person cannot cope with its dismantling. Due to this, it is actively used in places with seismic activity. Electricity will be supplied to the house 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 operating conditions, room features and other characteristics. Today on the market you can find a largea variety of devices from Russian manufacturers, which are distinguished by reasonable cost and high quality.
