Characteristics of cable tray manufacturers and pipeline erection

電纜橋架可以和工藝管道共架敷設(shè),不單獨(dú)占用電纜通道,節(jié)省空間,同時也避免了和地下管線交問題。

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.

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(yùn)行費(fèi)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 deal with it.

裝置擴(kuò)建時,增設(shè)的新電纜,可充分利用纜橋架的備用位置,十分方電便。

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.

隨著火災(zāi)報(bào)警系列產(chǎn)品的日趨完善,可利用纜式探測器對電纜進(jìn)行監(jiān)護(hù),一旦某處溫度過高,超過了探測器的設(shè)定值,可及時報(bào)警,使值班人員及時巡檢,解決隱患,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.

電纜橋架與其他電纜敷設(shè)方式相比,具有明顯的優(yōu)點(diǎn),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(jià)較低，但其占地面積大，裝置擴(kuò)建時增加電纜要重新開挖，常因擴(kuò)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(xiǎn)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(diǎn)，但因它處在地下，電纜多散熱條件差，一般需強(qiáng)制通風(fēng)，時時還受到滲漏的困擾，需定期排水，運(yùn)行費(fèi)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(diǎn)。

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.
