Information

Compared with other cable laying methods, cable trays have obvious advantages. Cable bridges can be used regardless of the main line of the plant or the wiring inside a certain device. Although the cable is directly buried, the construction cost is low, but the floor space is large. When the device is expanded, the cable should be re-excavated. The cable is often damaged due to expansion and construction, resulting in power failure, and the accident handling is difficult. It takes a long time to restore the power supply. When the cable is buried directly, the armored cable is required, and the price is more expensive than the general cable, and the bending is inconvenient. Although the cable trench scheme has certain flexibility compared with direct cable burying, most petrochemical enterprises are inflammable and explosive places. Cable trenches tend to accumulate dangerous gases, causing hidden dangers, and chemical surface water mostly contains chemical materials, which takes a long time. It will inevitably cause pollution to the cable trench. The cable trench is generally about one meter deep and has a cover plate. It is inconvenient for personnel to inspect. Although the cable tunnel has the characteristics of maintenance and cable increase, because it is underground, the cable has poor heat dissipation conditions, generally requires forced ventilation, and is often troubled by leakage. It needs regular drainage and high operating cost. The cable tunnel can only be used in the concentrated area of ​​the cable. After the cable is taken out, the direct burial or cable trenching method still needs to be adopted, and the disadvantage of this method is inevitable.
