電纜橋架的敷設(shè)

Laying of cable tray

電纜橋架可與工藝管線一起鋪設(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。

The cable tray can be laid together with the process pipeline without occupying the cable channel separately, so as to save space and avoid the problem of crossing with underground pipelines.

電纜在空中敷設(shè)，散熱條件比電纜隧道好，無(wú)需通風(fēng)排水，運(yùn)行成本低。擴(kuò)建安裝時(shí)，新增的電纜可以充分利用電纜橋架的空閑位置，用電非常方便。

When the cable is laid in the air, the heat dissipation condition is better than that of the cable tunnel. There is no need for ventilation and drainage, and the operation cost is low. During the expansion and installation, the new cables can make full use of the idle position of the cable tray, which is very convenient for power consumption.

與其他電纜鋪設(shè)方式相比，電纜橋架具有明顯的優(yōu)勢(shì)。無(wú)論廠區(qū)的主線還是某臺(tái)設(shè)備內(nèi)的布線，都可以采用電纜橋架的敷設(shè)方式。直埋電纜雖然成本低，但占地面積大。當(dāng)安裝擴(kuò)大時(shí)，電纜需要重新開(kāi)挖。

Compared with other cable laying methods, cable tray has obvious advantages. No matter the main line in the plant area or the wiring in a certain equipment, the laying method of cable tray can be adopted. Although the cost of directly buried cable is low, it covers a large area. When the installation is expanded, the cable needs to be re excavated.

電纜經(jīng)常因擴(kuò)建施工而損壞，導(dǎo)致停電，事故處理難度大，恢復(fù)供電時(shí)間較長(zhǎng)，電纜直埋時(shí)，需要選擇鎧裝電纜，比普通電纜貴，彎折不方便。

The cable is often damaged due to expansion construction, resulting in power failure. It is difficult to deal with the accident and takes a long time to restore power supply. When the cable is directly buried, it is necessary to select armored cable, which is more expensive than ordinary cable and inconvenient to bend.

橋架水平敷設(shè)時(shí)，其離地高度一般不小于2.5m垂直敷設(shè)時(shí)，離地1.8m以下的部分應(yīng)有金屬蓋板保護(hù)，敷設(shè)在專用電氣室內(nèi)時(shí)除外。橋架應(yīng)水平敷設(shè)在設(shè)備夾層內(nèi)，或小于2.5m，并采取保護(hù)接地措施。

When the bridge is laid horizontally, its height above the ground is generally not less than 2.5m. When it is laid vertically, the part below 1.8m above the ground shall be protected by a metal cover plate, except when it is laid in a special electrical room. The bridge shall be horizontally laid in the equipment interlayer, or less than 2.5m, and protective grounding measures shall be taken.

電纜橋架的敷設(shè)布置

在工程設(shè)計(jì)中，橋架的布置應(yīng)根據(jù)經(jīng)濟(jì)合理性、技術(shù)可行性、運(yùn)營(yíng)性等因素進(jìn)行綜合比較。確定一個(gè)好的方案，充分滿足施工、安裝、維護(hù)和電纜敷設(shè)的要求。

In the engineering design, the layout of the bridge shall be comprehensively compared according to the economic rationality, technical feasibility, operation safety and other factors. Determine a good scheme to fully meet the requirements of construction, installation, maintenance and cable laying.

當(dāng)在腐蝕環(huán)境中使用時(shí)，橋架、線槽、支吊架應(yīng)采用耐腐蝕的剛性材料。或采用防腐處理，防腐處理方法應(yīng)滿足工程、環(huán)境和耐久性的要求。對(duì)于耐腐蝕或潔凈度要求高的場(chǎng)所，應(yīng)選用鋁合金電纜橋架。

When used in corrosive environment, the tray, trunking, supports and hangers shall be made of corrosion-resistant rigid materials. Or adopt anti-corrosion treatment. The anti-corrosion treatment method shall meet the requirements of the project, environment and durability. For places with high requirements for corrosion resistance or cleanliness, aluminum alloy cable trays shall be selected.

在有防火要求的地區(qū)，山東電纜橋架、電纜槽可加防火或阻燃板、網(wǎng)等材料，形成封閉或半封閉結(jié)構(gòu)。

In areas with fire protection requirements, Shandong cable tray and cable trough can be added with fire-proof or flame-retardant plates, nets and other materials to form a closed or semi closed structure.

山東電纜橋架及其支吊架表面噴涂防火涂料等措施。其整體耐火性能應(yīng)滿足相關(guān)規(guī)范或標(biāo)準(zhǔn)的要求。鋁合金電纜橋架不應(yīng)用于防火要求高的場(chǎng)所。

The surface of Shandong cable tray and its supports and hangers shall be sprayed with fireproof paint and other measures. The overall fire resistance performance shall meet the requirements of relevant national codes or standards. Aluminum alloy cable trays shall not be used in places with high fire protection requirements.

此外隨著火災(zāi)報(bào)警系列產(chǎn)品的改進(jìn)，電纜探測(cè)器可用于對(duì)電纜進(jìn)行監(jiān)控。一旦某處溫度過(guò)高，超過(guò)探測(cè)器設(shè)定值，可及時(shí)報(bào)警，以便值班人員及時(shí)巡查，隱患，以防意外。更多關(guān)于電纜橋架產(chǎn)品的事情您可以關(guān)注網(wǎng)站m.ymmgjx.net咨詢了解！

In addition, with the improvement of fire alarm 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, the alarm can be sent in time, so that the personnel on duty can patrol in time to eliminate hidden dangers and prevent accidents.
