Cable tray is an important equipment for cable laying and support, its installation requirements are to ensure the normal operation of the cable system is the key. Here are some requirements on the installation of cable tray:
1, safety: cable tray installation must give priority to safety. The installation process should pay attention to the safety of the operators, the use of appropriate safety equipment and personal protective equipment, and follow the relevant safety regulations. In addition, the installation location of the bridge should be away from flammable, explosive and other dangerous places.
2, laying planning: before installing the cable tray, should be electrically planned and designed to determine the laying path and length of each section of cable. According to different needs and environmental conditions, choose the right type and size of the bridge.

3, to determine the support mode: the support mode of the bridge has a variety of options, including hanging, hanging, wall and ground installation. According to the actual situation and requirements, choose the suitable support method, and ensure that the support points are evenly spaced, firm and reliable.
4, installation specifications: in the installation process, should be in accordance with the relevant installation specifications. According to the type and size of the bridge, carry out the correct and fixed to ensure that the connection between the components is tight and firm.
5, guide the laying of cables: After the installation is completed, it is necessary to guide the laying of cables. According to different system requirements, select the appropriate cable guide bracket or elbow, and keep the minimum bending radius of the cable to avoid excessive stretching or stranding of the cable and other problems.
6、Check and test: After the installation is completed, carry out the inspection and test of the bridge system. Check whether the fixing of each connection point is firm, whether the straightness and verticality of the bridge meet the requirements. At the same time, the cable connectivity test and insulation test to ensure the normal operation of the cable system.
To summarize, the installation requirements for cable trays include safety, planning, support methods, installation specifications, cable guidance laying and inspection and testing. Following these requirements will ensure the stability of the bridge system and the normal operation of the cable system, ensuring the smooth operation of electrical equipment in the industrial and commercial sectors.
