The cable tray can be laid together with the process pipeline, which does not occupy the cable channel separately, saving space and avoiding the problem of intersection with underground pipelines.

電纜敷設(shè)在空氣中,散熱條件比電纜隧道好,且不必通風(fēng)排水,運行費用低, 一旦電纜發(fā)生故障,處理也很方便。

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 handle it.

裝置擴建時,增設(shè)的新電纜,可充分利用電纜橋架的備用位置,十分方便。

When the device is expanded, the new cable added can make full use of the standby position of the cable tray, which is very convenient.

隨著火災(zāi)報警系列產(chǎn)品的日趨完善,可利用纜式探測器對電纜進行監(jiān)護,一旦某處溫度過高,超過了探測器的設(shè)定值,可及時報警,使值班人員及時巡檢,除掉隱患,以防造成事故。

With the gradual improvement of fire alarm series products, cable detectors can be used to monitor cables. Once the temperature at a certain place is too high and exceeds the set value of the detector, alarms can be given in time, so that the personnel on duty can patrol in time and remove hidden dangers to prevent accidents.

電纜橋架與其他電纜敷設(shè)方式相比,具有明顯的優(yōu)點,不論廠區(qū)主干線路或某個裝置內(nèi)的配線,均可采用電纜橋架敷設(shè)方式。電纜直埋雖然土建造價較低，但其占地面積大，裝置擴建時增加電纜要重新開挖，常因擴建施工等損壞電纜，造成停電事故，且事故處理困難，恢復(fù)供電所需時間較長，電纜直埋時需選用鎧裝電纜，其比一般電纜貴，彎曲不便。電纜溝方案雖然和電纜直埋相比，具有一定的靈活程度，但石化企業(yè)大多都是易燃易爆場所，電纜溝易聚集危險氣體，造成隱患，并且化工地表水大多含有化工物料，時間長了，必然會對電纜溝造成污染。電纜溝一般深一米左右，上有蓋板，人員巡檢多有不便。電纜隧道雖然具有維修，增加電纜方便的特點，但因它處在地下，電纜多散熱條件差，一般需強制通風(fēng)，時時還受到滲漏的困擾，需定期排水，運行費用高。電纜隧道只能在電纜集中地段使用，電纜引出后，仍需采用直埋或電纜溝方式，不可避免地又出現(xiàn)了該方式的缺點。

Compared with other cable laying methods, the cable tray has obvious advantages. No matter the main line in the plant or the wiring in a device, the cable tray laying method can be adopted. Although the civil engineering cost of direct cable burying is low, it covers a large area. During the expansion of the device, additional cables need to be re excavated. The cables are often damaged due to the expansion construction, resulting in power failure accidents. The accident handling is difficult, and the time required to restore power supply is long. Armored cables are required for direct cable burying, which are 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, and the cable trench is prone to accumulate dangerous gases, resulting in hidden dangers. Moreover, most chemical surface water contains chemical materials, which will inevitably pollute the cable trench over time. The cable trench is generally about one meter deep and has a cover plate, which makes it inconvenient for personnel to patrol. Although the cable tunnel has the characteristics of convenient maintenance and increased cable convenience, because it is underground, there are many cables and poor heat dissipation conditions, it generally needs forced ventilation, and it is troubled by leakage from time to time. It needs regular drainage, and the operation cost is high. The cable tunnel can only be used in the section where the cables are concentrated. After the cables are led out, they still need to be directly buried or cable trench, which inevitably leads to the disadvantages of this method.
