Cable trays are commonly used in the installation of power engineering, consisting of many accessories and support structures, which have the function of supporting and protecting cables. There are many functions, but do you know what they are used for? Most cables are very soft, and utilizing the characteristics of the architecture can effectively support the cables and provide a protective effect. Let's take a look at some of its specific functions.
1. Support cables
Attaching and supporting cables to buildings (structures) through their own structural characteristics, or independently supporting cables through tunnels or caves, underground, in the air, etc., mainly to support cables. It serves as the skeleton of the cable and attaches the cable to the cable tray to complete the installation. Due to the fact that most cables are flexible structures, they cannot be laid independently. By utilizing the rigid structure of cable trays, cables can be well supported.
2. Protective cable
Cable is like blood, its main function is to transmit various electrical energy, information transmission, information control, and so on. And hoist the cable for effective alignment. Cable protection.
For example, large-span cable trays can be used when laying power cables. It can effectively prevent sagging caused by the weight of the cable, avoid direct exposure of the cable to the atmosphere, and isolate direct damage to the cable caused by factors such as sunlight, fog, rain, snow, and wind. Effectively improving the service life of cables.
Slot type cable trays are used to lay control cables for highly sensitive systems such as computer cables, communication cables, and thermocouple cables, which have a good effect on shielding interference of control cables and protecting cables in heavily corrosive environments.
Fire-resistant cables can ensure that they can still work effectively for 30 minutes to 1 hour when encountering 700 ° C high temperatures, and can be used in high-temperature workshops or building environments with high fire protection requirements. Fire engineering cables.
The fiberglass type has high corrosion resistance and moisture resistance, and adopts a closed structure. When used in coastal areas and heavily corroded factories and mines, it can effectively protect cables from direct corrosion and damage caused by moisture.
Cable trays with different materials and structural forms have different functions, and the protection of cables is also diverse. Choosing suitable cable trays according to local conditions can meet the needs of cable protection under different conditions and environments.
