選擇不同的電纜橋架所需的條件
Cable bridge because of its own characteristics, types, applications are very wide, strict structural design, affordable, well liked by engineers. But there are many classifications of the bridge, which makes people headache.
從形式上看，有托盤，梯級，組合和槽式的形式，根據(jù)安裝形式的不同，選擇不同的橋架。重要的是表面做過處理的橋架，各有各的優(yōu)點和用處。
Form of view, there are pallets, rungs, combinations and trough type, according to the installation of different forms, choose different bridge. The most important thing is that the surface of the bridge has been processed, each has its own advantages and uses.
電纜橋架在電纜鋪設(shè)工程中發(fā)揮著基本的保證功能。對于高壓的電力電纜，我們應(yīng)根據(jù)不同的用電場景，選擇不同的電纜橋架。由此可見，室外控制電纜，配線電纜，室內(nèi)電纜等不同的場景需要選型不同的電纜橋架。
The cable tray plays the most basic guarantee function in the cable laying project. For high voltage power cables, we should select different cable trays according to different power consumption scenarios. This shows that outdoor control cables, distribution cables, indoor cables and other different scenes, the need for selection of different cable tray.
冷鍍鋅電纜橋架，經(jīng)過酸洗，表面光滑均勻。熱鍍鋅電纜橋架可以起到防腐的作用，用于室外。熱噴鋅涂層硬度強大，不會因外力而變形。不同類型的橋架應(yīng)該適用于不同的環(huán)境。
Cold galvanized cable bridge, after pickling, smooth surface uniform. Hot dip galvanized cable tray can play the role of corrosion protection, for outdoor use. The hot spraying zinc coating has a strong hardness and will not deform because of external force. Different types of bridge frames should be applied to different environments.
在電纜線和導(dǎo)線中，有一部分是有源電纜線，有一部分則是無源電纜線，比如我們常見的數(shù)據(jù)電纜和視頻同軸電纜線等等，這些都是無源電纜線的一種，因此，我們的工程師在進行對橋架纜線的布線方式和路由選擇的排列進行設(shè)計的時候，應(yīng)該對這兩種進行有效的區(qū)別，在設(shè)計的時候不僅僅要嚴(yán)格的符合規(guī)范的要求，同時還要考慮布線的性、經(jīng)濟性、可擴性以及美觀，并且要方便維修。
In cable and wire, a part of the active cable, one part is the passive cable, such as our common video data cable and coaxial cable and so on, these are a passive cable, therefore, our engineers in wiring on the bridge and cable routing arrangement design time that should be effective on the two kinds of difference, not only to strictly meet the specification requirements in the design of the time, while also considering the wiring safety and economy, scalability and appearance, and convenient maintenance.
電纜橋架作為承載各種電纜敷設(shè)的載體，在從屬于布線的需要，同樣也要遵循上述原則并且加以實施，由于在一些大型的建筑物內(nèi)，比如說大型的寫字樓和金融辦公樓等等，這些內(nèi)部就會存在很多種的管線平行交叉，在進行纜線敷設(shè)的時候除了要采用樓板溝槽和墻內(nèi)埋管方式之外，在豎井和屋內(nèi)天棚吊頂內(nèi)也要采用電纜橋架。
As the carrier of all kinds of cable bridge cable laying, from which belongs to the wiring, also follow the above principles and to be implemented, because in some large buildings, such as a large office building and financial office buildings and so on, there is a variety of parallel pipeline will cross these, when laying the cable in addition to the floor and trench buried in the wall tube, inside the drilled shafts and suspended ceilings also want to use the cable tray.
