The system for installing power lines and wires contains parts of varying complexity that are used to distribute energy and simplify the fastening process. A cable shelf is just one of such parts, created for the convenience and rationality of service, a presentable appearance.
It is produced mainly from profiles coated with zinc to protect against corrosion. Perforated material is used to increase the carrying loads. Cable shelf must comply with state standards, have 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 supporting integral structure is formed, since it cannot withstand the full load of the electrical wires. These items include the following:
- base for shelves;
- hardware materials;
- shelves for wires;
- racks for mounting to the ceiling.
In addition to the main parts, additional parts are used that are designed to separate or connect 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 electric cable to end consumers. The wiring protection from overheating and simplified access for repair are formed in this way. Shelves are used in situations where the installation of wires and lines by the hidden method is impractical or completely impossible. So they are load-bearing structures that form the location of the power track.
Specifications
A standard cable shelf, whose weight can reach 0.6-0.8 kg, has a U-shaped shape. There are various types of products that differ in such characteristics as permissible loads, compliance with climate conditions, design features, size. The profile expands somewhat towards the center, thus providing additional density. The cable shelf with a rack, which accounts for the weight of the structure, has the most durable fastening, and one person can not cope with its dismantling. Due to this, it is actively used in places with seismic activity. Electricity will come into the house even with a tangible earthquake. Each element has a galvanized coating and is suitable for subsequent painting. When choosing shelves, you need to build on operational conditions, room features and other characteristics. Today on the market you can find a wide variety of devices from Russian manufacturers, which are distinguished by reasonable cost and high quality.
