Characteristics of cable tray manufacturers and pipeline erection
The cable tray can be laid together with the process pipeline, which does not occupy the cable channel separately, which saves space and avoids the problem of intersection with underground pipelines.
When the cable is laid in the air, the heat dissipation condition is better than that of the cable tunnel, and there is no need for ventilation and drainage. The operation cost is low. Once the cable fails, it is also very convenient to deal with it.
When the device is expanded, the new cable added can make full use of the standby position of the cable bridge, which is very convenient.
With the gradual improvement of fire alarm series products, cable detectors can be used to monitor the cables. Once the temperature at a certain place is too high and exceeds the set value of the detector, the alarm can be given in time, so that the personnel on duty can conduct patrol inspection in time and solve hidden dangers to prevent accidents.
Compared with other cable laying methods, cable tray has obvious advantages. Cable tray laying method can be adopted regardless of the main line in the plant or the wiring in a device. Although the civil engineering cost of cable direct burial is low, it covers a large area. When the device is expanded, the additional cables need to be re excavated. The cables are often damaged due to expansion construction, resulting in power failure accidents, and the accident handling is difficult. It takes a long time to restore power supply. When the cables are directly buried, armored cables need to be selected, which is more expensive than ordinary cables and inconvenient to bend. Although the cable trench scheme has a certain degree of flexibility compared with the direct burial of cables, most petrochemical enterprises are flammable and explosive places. The cable trench is easy to accumulate dangerous gases and cause hidden dangers. Moreover, most chemical surface water contains chemical materials. Over time, it is bound to pollute the cable trench. The cable trench is generally about one meter deep with a cover plate on it, which is inconvenient for personnel to patrol. Although the cable tunnel has the characteristics of maintenance and convenience of increasing cables, it generally needs forced ventilation due to its underground location, many cables and poor heat dissipation conditions. It is also plagued by leakage from time to time, regular drainage is required, and the operation cost is high. The cable tunnel can only be used in the cable concentrated section. After the cable is led out, it still needs to be directly buried or cable trench, which inevitably has the disadvantages of this method.
