The cable bridge will naturally encounter various problems in use, which is not very good for the cable bridge, because the rainy season weather is more common, the cable bridge production equipment should be away from the doors and windows, to prevent the invasion of outdoor rain and humid air. Before starting production, workers shall check the power supply, switch and other components to ensure that everything is normal before production and the power supply and other components are not affected with damp. In the production process, workers should always pay attention to the pointer and circuit on the equipment, and do not have electrical accidents such as power connection.
The raw materials of cable tray are usually stored indoors. If the foreign metal material is used for production, it is recommended that you clean it before use to prevent metal and rainwater from entering the production equipment, which will cause the equipment to be affected by humidity or power, which is also very harmful production. After the completion of production, the cable bridge factory shall cut off the power supply in time and conduct a comprehensive inspection of the equipment circuit to ensure that there is no danger of electricity before leaving.
Cable bridge is not a device for managing cables, but for protecting power safety. When installing cable tray, the manufacturer shall fully consider the requirements of working environment and carry out reasonable fire protection design.
It is a simple and effective method to seal the cable through the wall hole with fireproof material, and it can also prevent the air from leaking through the wall.
One method of fire protection design is to separate different types of cables. Different types of cables have different widths and even rated voltages. In use, due to heat dissipation and other problems, fire is inevitable. Therefore, different types of cables should be laid from top to bottom according to the high-voltage cable layer, power cable layer and control cable layer.
The second fire protection design method is to add fire walls and fire doors. Every 100m of the main gallery is provided with a fire section, and every 60m of the cable tray is provided with a firewall. Fireproof filler, fireproof partition and inorganic materials are the main components of fireproof doors and firewalls.
The third method of fire protection design is to separate the floors. In other words, add fire-proof materials to the cable tray layer to make a fire-proof cover, and set a fire-proof board every three layers to prevent the fire from spreading. The above four methods are applied comprehensively, and the fire prevention effect is good.
Electric power is an indispensable energy in production and life. As an important medium of power transmission, cable bridge naturally needs regular maintenance in such winter. The cable bridge manufacturer will explain the maintenance content for you. The scope of use of cable bridge is generally divided into indoor and outdoor. For the cable tray installed indoors, the maintenance should pay attention to the stability, fire resistance and flame retardancy of the installation, because the indoor environment is relatively simple, the safety risks are relatively few, and the maintenance of workers is relatively simple.
Different from indoor, the maintenance of outdoor cable tray is more complex, especially in the field. First, outdoor and wilderness areas need to be exposed to extreme natural weather. In addition, at present, the environment is bad and the corrosion is serious. During bridge maintenance, whether the screws on the bridge are loose and whether the important connections are corroded are the contents that need to be maintained. In addition, whether the cable on the bridge is in good condition and whether the transmission process is smooth is also within the scope of maintenance.
