There are many advantages of cable bridge laying in Jinan. Why should cable bridge laying be adopted? I summarize the following points for you.

1.濟(jì)南電纜橋架可與工藝管共架敷設(shè)，不單獨(dú)占用電纜通道，節(jié)省空間，避免與地下管線交叉的問(wèn)題。

1. Jinan cable tray can be laid on the same frame with the process pipe without occupying the cable channel separately, saving space and avoiding the problem of crossing with underground pipelines.

2.線纜敷設(shè)在空氣中，比電纜隧道的散熱條件好，不需通風(fēng)、排水，運(yùn)行費(fèi)用低，一旦出現(xiàn)故障，處理也非常方便。

2. The cable laid in the air has better heat dissipation conditions than the cable tunnel. It does not need ventilation and drainage, and the operation cost is low. In case of failure, it is also very convenient to deal with it.

3.在擴(kuò)建中增設(shè)新電纜，可以充分利用電纜橋架的備用位置，非常方便。

3. Adding new cables in the expansion can make full use of the standby position of cable tray, which is very convenient.

4.隨著火警系列產(chǎn)品的日益完善，可使用纜式探測(cè)器監(jiān)測(cè)電纜，一旦某個(gè)地方溫度過(guò)高，超過(guò)設(shè)定的檢測(cè)器設(shè)定值，就能及時(shí)報(bào)警，使值班人員及時(shí)發(fā)現(xiàn)隱患，以排除隱患。

4. With the increasing improvement of fire alarm series products, cable detectors can be used to monitor cables. Once the temperature in a place is too high and exceeds the set value of the detector, an alarm can be given in time, so that the personnel on duty can find hidden dangers in time to eliminate hidden dangers.

5.與其它敷設(shè)方式相比，濟(jì)南電纜橋架具有明顯的優(yōu)勢(shì)，無(wú)論在廠區(qū)主干線路還是在某一設(shè)備內(nèi)，都可以采用電纜橋架敷設(shè)方式。纜直埋管雖然土建成本較低，但其占地面積大，在裝置擴(kuò)建時(shí)增加電纜要重新開(kāi)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(shí)間較長(zhǎng)，電纜直埋時(shí)需要用鎧裝電纜，要比一般電纜貴。盡管電纜溝方案與電纜直埋相比有一定的靈活性，但石化企業(yè)大多是易燃易爆的場(chǎng)所，電纜溝易聚集危險(xiǎn)氣體，造成隱患，而且化工地表水大多含有化工物料，而且化工地表水大多含有化學(xué)物質(zhì)。

5. Compared with other laying methods, Jinan cable tray has obvious advantages. The cable tray laying method can be adopted whether in the main line of the plant or in a certain equipment. Although the civil engineering cost of cable directly buried pipe is low, it covers a large area. When increasing the cable during the expansion of the device, it is necessary to re excavate. The cable is often damaged due to the expansion construction, resulting in power failure accidents, and the accident handling is difficult. It takes a long time to restore the power supply. Armored cable is required when the cable is directly buried, and the price is more expensive than ordinary cable. Although the cable trench scheme has certain flexibility compared with the direct burial of cables, most petrochemical enterprises are flammable and explosive places, and the cable trench is easy to accumulate dangerous gases, resulting in hidden dangers. Moreover, most chemical surface water contains chemical materials, and most chemical surface water contains chemical substances.

電纜溝一般深一米左右，上面有蓋板，人員巡視多有不便。盡管電纜隧道具有檢修、增加電纜方便的特點(diǎn)，但由于它位于地下，電纜多散熱性差，一般需要強(qiáng)制通風(fēng)，時(shí)時(shí)也受滲漏之苦，需要定期排水，運(yùn)行費(fèi)用高。由于電纜隧道只能在集中的地段使用，電纜引出后，仍需采用直埋或溝敷設(shè)的方式，不可避免地也存在這種弊端。

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 convenient maintenance and increasing cables, because it is located underground, there are many cables and poor heat dissipation, it generally needs forced ventilation, suffers from leakage from time to time, needs regular drainage, and the operation cost is high. Since the cable tunnel can only be used in concentrated sections, it is still necessary to adopt the method of direct burial or trench laying after the cable is led out, which inevitably has this disadvantage.
