Characteristics of cable tray manufacturers and pipeline erection

电缆桥架可以和工艺管道共架敷设,不单独占用电缆通道,节省空间,同时也避免了和地下管线交问题。

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.

电缆敷设在空气中,散热条件比电缆隧道好,且不必通风排水,运行费用低,一旦电缆发生故障,处理也很方便。

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.

装置扩建时,增设的新电缆,可充分利用缆桥架的备用位置,十分方电便。

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.

随着火灾报警系列产品的日趋完善,可利用缆式探测器对电缆进行监护,一旦某处温度过高,超过了探测器的设定值,可及时报警,使值班人员及时巡检,解决隐患,以防造成事故。

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.

电缆桥架与其他电缆敷设方式相比,具有明显的优点,不论厂区主干线路或某个装置内的配线,均可采用电缆桥架敷设方式。电缆直埋虽然土建造价较低，但其占地面积大，装置扩建时增加电缆要重新开挖，常因扩建施工等损坏电缆，造成停电事故，且事故处理困难，恢复供电所需时间较长，电缆直埋时需选用铠装电缆，其比一般电缆贵，弯曲不便。电缆沟方案虽然和电缆直埋相比，具有一定的灵活程度，但石化企业大多都是易燃易爆场所，电缆沟易聚集危险气体，造成隐患，并且化工地表水大多含有化工物料，时间长了，必然会对电缆沟造成污染。电缆沟一般深一米左右，上有盖板，人员巡检多有不便。电缆隧道虽然具有维修，增加电缆方便的特点，但因它处在地下，电缆多散热条件差，一般需强制通风，时时还受到渗漏的困扰，需定期排水，运行费用高。电缆隧道只能在电缆集中地段使用，电缆引出后，仍需采用直埋或电缆沟方式，不可避免地又出现了该方式的缺点。

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.
