電纜橋架普遍作用有三個：支撐線纜、保護線纜、管理線纜。

Cable trays have three common functions: supporting cables, protecting cables, and managing cables.

支撐線纜、光纖是電纜橋架主要的作用，比如采用歐洲焊接技術的網格橋架，每個焊點能夠承載500公斤重量的線纜、光纖。梯式橋架對一些大跨距的電纜橋架擁有很好的支撐性，因此很多對承載力要求高的綜合布線，都使用大跨距橋架。

Supporting cables and optical fibers are the main functions of cable trays, such as grid trays using European welding technology, where each welding point can carry a weight of 500 kilograms of cables and optical fibers. Ladder type cable trays have good support for some large-span cable trays, so many comprehensive cabling systems that require high load-bearing capacity use large-span cable trays.

槽式橋架具有全封閉結構，對線纜可以起到很好的保護作用，室內布線，防止電磁干擾、防止螞蟻、老鼠的的破壞。室外使用槽式橋架可以防止雷電、雨雪等自然環境對電纜的破壞。不僅如此，在使用鋁合金材質的橋架經過陽極氧化后得到的鋁合金槽式橋架，更有防腐蝕、防銹、高耐磨等特點，也是國內使用較為流通的電纜橋架之一。

The trough type cable tray has a fully enclosed structure, which can provide good protection for cables. Indoor wiring prevents electromagnetic interference and damage from ants and mice. The use of trough type cable trays outdoors can prevent damage to cables from natural environments such as lightning, rain, and snow. Not only that, the aluminum alloy trough type cable tray obtained by anodizing the cable tray made of aluminum alloy material has characteristics such as corrosion resistance, rust prevention, and high wear resistance, and is also one of the more widely used cable trays in China.

管理線纜，由于電纜橋架的開放式結構，因此線纜不管是在前期的安裝，還是后期的添加線纜、維護線纜，都可以很方便快速的更換維護。這也是應對現代大數據中心電氣化有效的解決方案。

Managing cables, due to the open structure of cable trays, cables can be easily and quickly replaced and maintained during the early installation, as well as the subsequent addition and maintenance of cables. This is also an effective solution to address the electrification of modern big data centers.

除此以外，電纜橋架經過鍍鋅、熱浸鋅、防火涂料等特殊工藝處理，使電纜橋架的功能越來越強大，在應對各種電磁干擾、防火、防塵等環境中發揮著舉足輕重的作用，電纜橋架正不斷的在各行業廣泛使用。

In addition, cable trays have undergone special processes such as galvanizing, hot-dip galvanizing, and fire-resistant coatings, making their functions increasingly powerful. They play a crucial role in dealing with various electromagnetic interference, fire prevention, dust prevention, and other environments. Cable trays are constantly being widely used in various industries.
