在辦公樓、商業(yè)綜合體、酒店等民用建筑中，電纜橋架是電氣布線的核心載體。這類(lèi)場(chǎng)景中，電力電纜需為照明、空調(diào)、辦公設(shè)備供電，控制電纜則連接樓宇自控系統(tǒng)，而橋架能將不同功能的電纜分類(lèi)敷設(shè)，避免信號(hào)干擾。通常選用槽式或托盤(pán)式橋架，前者可保護(hù)電纜免受灰塵、輕微碰撞影響，后者便于檢修時(shí)觀察電纜狀態(tài)。例如，在高層寫(xiě)字樓的吊頂內(nèi)，橋架沿梁或鋼結(jié)構(gòu)敷設(shè)，將電纜從配電室引至各樓層配電箱，安裝靈活且后期維護(hù)成本低。

In office buildings, commercial complexes, hotels, and other civil buildings, cable trays are the core carriers for electrical wiring. In such scenarios, power cables need to supply electricity to lighting, air conditioning, and office equipment, while control cables connect the building automation system. Cable trays can lay cables of different functions in categories to avoid signal interference. Trough-type or tray-type cable trays are usually selected: the former can protect cables from dust and slight collisions, and the latter facilitates observing the cable status during maintenance. For example, in the ceiling of a high-rise office building, cable trays are laid along beams or steel structures to lead cables from the power distribution room to the distribution boxes on each floor, featuring flexible installation and low later maintenance costs.

汽車(chē)制造、機(jī)械加工、冶金等工業(yè)廠房對(duì)電纜橋架的承載能力和耐環(huán)境性要求更高。這類(lèi)場(chǎng)景中，電纜不僅數(shù)量多，還常伴隨大功率設(shè)備的重型電纜，且環(huán)境可能存在油污、振動(dòng)、高溫等問(wèn)題。因此，多采用鋼制梯式橋架或鋁合金橋架 —— 梯式橋架的鏤空結(jié)構(gòu)利于散熱，適配高溫環(huán)境下的電纜敷設(shè)；鋁合金橋架則憑借輕量化和抗油污腐蝕的特點(diǎn)，適合機(jī)械加工車(chē)間的頻繁設(shè)備移動(dòng)場(chǎng)景。例如，在汽車(chē)焊接車(chē)間，橋架需承載焊接設(shè)備的高壓電纜，其厚度和跨距設(shè)計(jì)需滿(mǎn)足重載需求，同時(shí)表面的防腐涂層能抵御焊接煙塵的侵蝕。

Industrial plants such as automobile manufacturing, machinery processing, and metallurgy have higher requirements for the load-bearing capacity and environmental resistance of cable trays. In such scenarios, there are not only a large number of cables but also heavy-duty cables for high-power equipment, and the environment may have problems such as oil pollution, vibration, and high temperature. Therefore, steel ladder-type cable trays or aluminum alloy cable trays are mostly used: the hollow structure of ladder-type cable trays is conducive to heat dissipation, which is suitable for cable laying in high-temperature environments; aluminum alloy cable trays, with the characteristics of lightweight and oil pollution corrosion resistance, are suitable for frequent equipment movement scenarios in machinery processing workshops. For example, in an automobile welding workshop, cable trays need to carry high-voltage cables of welding equipment, and their thickness and span design must meet heavy-load requirements, while the anti-corrosion coating on the surface can resist the erosion of welding fumes.

數(shù)據(jù)中心是電纜橋架的高密度應(yīng)用場(chǎng)景，服務(wù)器、交換機(jī)、存儲(chǔ)設(shè)備等需大量數(shù)據(jù)電纜和電力電纜連接，對(duì)布線的規(guī)整性和擴(kuò)容性要求嚴(yán)苛。此處多選用托盤(pán)式橋架或網(wǎng)格橋架，托盤(pán)式橋架能容納多根超六類(lèi)網(wǎng)線、光纖及電源線，分類(lèi)敷設(shè)可降低電磁干擾；網(wǎng)格橋架則因開(kāi)放性結(jié)構(gòu)，便于電纜散熱和快速增減線路，適配數(shù)據(jù)中心頻繁的設(shè)備升級(jí)需求。例如，在大型云計(jì)算數(shù)據(jù)中心，橋架沿機(jī)柜列平行敷設(shè)，通過(guò)分支橋架直接連接各機(jī)柜，實(shí)現(xiàn) “機(jī)柜 - 橋架 - 配電室” 的無(wú)縫布線，保障數(shù)據(jù)傳輸?shù)姆€(wěn)定性。

Data centers are high-density application scenarios for cable trays. Servers, switches, storage devices, and other equipment require a large number of data cables and power cables for connection, which have strict requirements for the regularity and expandability of wiring. Tray-type cable trays or grid cable trays are mostly used here: tray-type cable trays can accommodate multiple Cat6a network cables, optical fibers, and power cables, and classified laying can reduce electromagnetic interference; grid cable trays, due to their open structure, facilitate cable heat dissipation and rapid addition/removal of lines, adapting to the frequent equipment upgrade needs of data centers. For example, in a large cloud computing data center, cable trays are laid parallel to the cabinet rows, and each cabinet is directly connected through branch cable trays, realizing seamless wiring from "cabinet - cable tray - power distribution room" and ensuring the stability of data transmission.

地鐵、高鐵站、機(jī)場(chǎng)、高速公路等交通基礎(chǔ)設(shè)施中，電纜橋架主要用于敷設(shè)信號(hào)控制電纜、監(jiān)控電纜和動(dòng)力電纜。這類(lèi)場(chǎng)景多處于地下或露天環(huán)境，潮濕、振動(dòng)、電磁干擾是主要挑戰(zhàn)。例如，地鐵隧道內(nèi)選用防腐性能優(yōu)異的熱浸鍍鋅鋼制橋架，其表面鍍鋅層厚度≥65μm，可抵御隧道內(nèi)的潮濕水汽；同時(shí)，橋架通過(guò)防震支架固定，減少列車(chē)通行時(shí)的振動(dòng)對(duì)電纜連接的影響。在高速公路的收費(fèi)站，橋架則沿收費(fèi)大棚鋼結(jié)構(gòu)敷設(shè)，為收費(fèi)系統(tǒng)、監(jiān)控?cái)z像頭和照明設(shè)備傳輸電力與信號(hào)。

In transportation infrastructures such as subways, high-speed railway stations, airports, and expressways, cable trays are mainly used to lay signal control cables, monitoring cables, and power cables. Most of these scenarios are in underground or open-air environments, with moisture, vibration, and electromagnetic interference as the main challenges. For example, hot-dip galvanized steel cable trays with excellent anti-corrosion performance are selected in subway tunnels, and their surface galvanized layer thickness is ≥65μm, which can resist the humid water vapor in the tunnels; at the same time, the cable trays are fixed by anti-vibration brackets to reduce the impact of vibration during train passage on cable connections. At the toll stations of expressways, cable trays are laid along the steel structure of the toll shed to transmit power and signals for the toll system, surveillance cameras, and lighting equipment.

火電廠、風(fēng)電場(chǎng)、水電站等能源設(shè)施中，電纜橋架需承載大量高壓、大截面電纜，且常面臨戶(hù)外、高溫或多粉塵環(huán)境?；痣姀S的汽機(jī)房?jī)?nèi)，高溫環(huán)境要求橋架選用耐高溫鋼制橋架，其板材厚度比常規(guī)橋架增加 0.5-1.0mm，以避免高溫變形；風(fēng)電場(chǎng)的風(fēng)機(jī)塔筒內(nèi)，橋架需沿塔筒垂直敷設(shè)，因空間狹窄，多采用緊湊型梯式橋架，既節(jié)省空間又便于電纜檢修。在水電站的廠房?jī)?nèi)，橋架還需具備一定的防水性能，防止水汽進(jìn)入電纜絕緣層，保障發(fā)電設(shè)備的穩(wěn)定運(yùn)行。

In energy facilities such as thermal power plants, wind farms, and hydropower stations, cable trays need to carry a large number of high-voltage and large-section cables, and often face outdoor, high-temperature, or dusty environments. In the turbine room of a thermal power plant, the high-temperature environment requires the selection of high-temperature resistant steel cable trays, whose plate thickness is 0.5-1.0mm thicker than conventional cable trays to avoid high-temperature deformation; in the wind turbine tower of a wind farm, cable trays need to be laid vertically along the tower. Due to the narrow space, compact ladder-type cable trays are mostly used, which not only save space but also facilitate cable maintenance. In the plant of a hydropower station, the cable trays also need to have a certain waterproof performance to prevent water vapor from entering the cable insulation layer and ensure the stable operation of power generation equipment.

化工廠、制藥廠、海邊化工園區(qū)等場(chǎng)景中，空氣中含有酸堿氣體、腐蝕性液體揮發(fā)物，對(duì)電纜橋架的防腐性能提出極高要求。常規(guī)鋼制橋架易被腐蝕，因此多選用玻璃鋼（FRP）橋架或襯塑鋼制橋架。玻璃鋼橋架的氧指數(shù)≥35，不僅耐酸堿腐蝕，還具備防火性能，適合敷設(shè)輸送化工原料管道旁的電纜；襯塑鋼制橋架則在鋼制橋架內(nèi)壁復(fù)合防腐塑料層，既保留鋼制橋架的承載能力，又能抵御化工環(huán)境的腐蝕。例如，在海邊鹽化工園區(qū)，玻璃鋼橋架沿裝置區(qū)的管廊敷設(shè)，為反應(yīng)釜、計(jì)量泵等設(shè)備的控制電纜提供保護(hù)。

In scenarios such as chemical plants, pharmaceutical factories, and coastal chemical parks, the air contains acid-base gases and volatile corrosive liquids, which put extremely high requirements on the anti-corrosion performance of cable trays. Conventional steel cable trays are easily corroded, so fiberglass reinforced plastic (FRP) cable trays or plastic-lined steel cable trays are mostly used. The oxygen index of FRP cable trays is ≥35, which is not only acid and alkali corrosion resistant but also has fire resistance, suitable for laying cables next to pipelines that transport chemical raw materials; plastic-lined steel cable trays are composite with anti-corrosion plastic layers on the inner wall of steel cable trays, which not only retain the load-bearing capacity of steel cable trays but also resist corrosion in chemical environments. For example, in a coastal salt chemical park, FRP cable trays are laid along the pipe gallery in the device area to protect the control cables of reactors, metering pumps, and other equipment.
