Laying cable trays

## laying cable trays: order and safety
Cable trays are an indispensable element of modern electric installation. They allow you to organize the laying of cables and wires, ensuring safety, order and ease of maintenance. The correct laying of cables in the trays is the key to the long and uninterrupted operation of the entire electric system, whether in the office, in production or in a residential building. Let's figure out how to do it right.
### Preparation and Selection of Lots
Before starting work, it is necessary to carefully plan the cable laying route. Consider the location of electrical panels, workplaces, lighting devices and other elements of the mains. Choose a suitable type of trays: perforated (for better ventilation), deaf (for protection against dust and moisture) or stairwell (for large volumes of cables). It is also important to take into account the load - the quantity and diameter of the cables. Do not save on the quality of the trays - a reliable design will ensure the durability of the entire system. Stell the necessary fasteners: clamps, holders and suspensions.
### Cable laying process
The laying of cables in the trays should be carried out carefully and sequentially. Cables should be laid evenly, without excesses and excessive tension. A group of wires of the same purpose is better grouped together and marked for the convenience of identification. Too dense styling can lead to overheating and damage to insulation. When using perforated trays, provide a sufficient distance between the cables for air circulation. Do not forget about the reserve - take into account the possible expansion of the network in the future. For large volumes of cables, it is recommended to use separators inside the tray to organize bundles.
### final stages and safety
After the cable laying is completed, it is necessary to fix the trays reliably. Check all the connections, make sure that the cables are not pushed or damaged. Properly installed and fixed trays exclude sagging cables, increase fire safety and simplify subsequent maintenance. Remember that working with electricity requires caution. If necessary, attract qualified specialists. Correctly performed laying cables in trays is a guarantee of safety and uninterrupted operation of your power grid for many years.
