Cable tray classification

目前市場(chǎng)上比較常見的橋架主要分為兩大類，一類是國(guó)外比較受歡迎的開放式電纜橋架，開放式電纜橋架主要以網(wǎng)格橋架為主，另一類就是國(guó)內(nèi)工程項(xiàng)目較常使用的全封閉或半封閉式的槽式橋架、梯式橋架、托盤式橋架；除此之外，電纜橋架還有玻璃鋼橋架等等。

At present, the commonly used cable trays in the market are mainly divided into two categories. One type is the popular open cable tray abroad, which is mainly composed of grid cable trays. The other type is the fully enclosed or semi enclosed trough type cable tray, ladder type cable tray, and tray type cable tray commonly used in domestic engineering projects; In addition, there are also fiberglass cable trays and so on.

并且根據(jù)材質(zhì)不同，電纜橋架主要有幾大類，不銹鋼橋架、鋁合金橋架、玻璃鋼橋架以及PVC橋架。

And according to the different materials, there are several main types of cable trays, including stainless steel trays, aluminum alloy trays, fiberglass trays, and PVC trays.

電纜橋架的作用

The role of cable trays

電纜橋架普遍作用有三個(gè)：支撐線纜、保護(hù)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(shù)的網(wǎng)格橋架，每個(gè)焊點(diǎn)能夠承載500公斤重量的線纜、光纖。梯式橋架對(duì)一些大跨距的電纜橋架擁有很好的支撐性，因此很多對(duì)承載力要求高的綜合布線，都使用大跨距橋架。

Supporting cables and optical fibers is the main function 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 wiring systems with high load-bearing requirements use large-span cable trays.
