Installation of cable trays

## installation of cable trays
Cable trays are an indispensable element of modern electric installation. They provide safe and organized laying of cables and wires, protecting them from mechanical damage and providing convenience of maintenance. Proper installation of trays is the key to durability and reliability of the entire system. But how to do this right? Let's figure it out.
### preparatory stage: planning and calculations
Before starting work, it is necessary to carefully plan the location of the trays. It is important to take into account the number and type of cables, the distance between the supports, the presence of obstacles (pipes, walls, engineering communications) and, of course, safety requirements. It is necessary to make accurate measurements and calculate the required number of trays, fasteners and additional accessories (corners, tees, crosses). The correct calculation will avoid unnecessary costs and problems in the installation process. Do not forget about the availability for subsequent maintenance and repair - free access should always be provided to cables.
## direct installation: from simple to complex
The installation process itself is relatively simple, but requires accuracy and attentiveness. First, brackets are installed for attaching trays to the walls, ceilings or other structures. The distance between the supports depends on the type of tray and its load, but usually does not exceed 1.5-2 meters. Then, in fact, the trays are installed, connecting to each other using the necessary connecting elements. It is important to monitor the horizontal and vertical installation in order to avoid distortions and sagging. When working at altitude, do not forget about security measures - use safety belts and other protective equipment.
### The final stage: checking and grounding
After the installation is completed, it is necessary to carry out a thorough check of the entire system. Make sure that all connections are reliable, the trays are installed smoothly and firmly, and the laying of cables does not violate safety requirements. Pay special attention to grounding - this is a critical aspect that provides protection against electric shock. Correctly performed grounding of trays is a prerequisite for the safe operation of the entire electric system. Only after all the checks can the installation of cable trays be considered completed.
