With the development of machinery, cable tray is widely used in engineering construction. If we don't know what problems should be paid attention to in the installation of cable tray, the cable tray will be seriously damaged by the environment after installation, and the whole line will be damaged. Therefore, we need to know what problems should be paid attention to in the installation of cable tray, so that we can use it better in engineering construction.

我們需要了解電纜橋架的安裝需要對環境條件進行綜合分析 ，一般情況下我們將環境條件劃分為三種，分別是正常環境、特殊環境、以及腐蝕環境，不同的環境對電纜橋架的安裝要求也不盡相同。其次，電纜橋架的安裝要注意確定電纜橋架的走向，電纜橋架的安裝確定時應該以多數電纜的走向為依據，在室外環境中走向可以沿著工藝管道，而在室內的時候沿著梁，柱，墻等均可。

First of all, we need to understand the installation of cable tray, and we need to make a comprehensive analysis of the environmental conditions. Generally, we divide the environmental conditions into three kinds, namely normal environment, special environment, and corrosive environment. Different environments have different requirements for the installation of cable tray. Secondly, the installation of cable tray should pay attention to determine the direction of cable tray. The installation of cable tray should be based on the direction of most cables. In the outdoor environment, the direction can be along the process pipeline, while in the indoor environment, it can be along the beam, column, wall, etc.

電纜橋架的安裝要注意荷重的計算，計算時需要的數據是處于斷面上的電纜單位長度上的重量以及橋架的總荷載量的。的也是更重要的一點，電纜橋架的安裝需要綜合前三點的條件來進行橋架的類型和規格的確定，選擇時需要考慮的參數有立柱的長度以及間距，橋架的層次，托臂的長度等。

The installation of cable tray should pay attention to the calculation of load. The data needed for calculation are the weight of the cable unit length on the section and the total load of the tray. The last and most important point is that the installation of cable tray needs to integrate the conditions of the first three points to determine the type and specification of the cable tray. The parameters to be considered in the selection include the length and spacing of columns, the level of the cable tray, the length of the bracket, etc.

施工環境當中需要防火要求時，可以選擇相應的防火電纜橋架，防火電纜橋架的整體防火性能要求需要符合有光規范或標準的要求。這就是對環境條件進行的綜合分析。

When the construction environment needs fire protection requirements, the corresponding fire-proof cable tray can be selected, and the overall fire performance requirements of fire-proof cable tray need to meet the requirements of national light codes or standards. This is a comprehensive analysis of environmental conditions.

選擇電纜橋架的負載等級時，橋架的平均工作負載不應大于所選電纜橋架的額定平均工作負載。電纜橋架支吊架實際跨度不等于2m時，平均工作荷載應滿足要求。

When selecting the load level of the cable tray, the average working load of the tray should not be greater than the rated average working load of the selected cable tray. When the actual span of cable tray support is not equal to 2m, the average working load shall meet the requirements.
