槽式電纜橋架是現代電纜防護設備中為常用的一種托盤結構橋架，槽式電纜橋架對于電纜傳輸完整信號和電纜分類管理都有很好的作用，槽式電纜橋架板材厚度在橋架相關相關標準例如JB/T 10216-2013中都有明確規定，不同材質、不同寬度的濟南電纜橋架的厚度是不同的。相關知識點整理如下：

Trough type cable tray is a kind of tray structure tray commonly used in modern cable protection equipment. Trough type cable tray plays a very good role in complete signal transmission and cable classification management. The thickness of trough type cable tray is clearly specified in relevant standards of cable tray, such as JB/T 10216-2013. The thickness of Jinan cable tray with different materials and different widths is different. Relevant knowledge points are summarized as follows:

槽式電纜橋架改向彎通包括：垂直左上彎通、垂直右上彎通、垂直左下彎通、垂直右下彎通、垂直左上三通、垂直右上三通等。托盤重量和蓋板重量構成了槽式槽式電纜橋架的主要重量，例如普通鍍鋅槽式電纜橋架規格100*50mm規格，托盤每米重量為3.67千克，蓋板每米的重量為2.20千克。

Channel type cable tray bend includes: vertical left upper bend, vertical right upper bend, vertical left lower bend, vertical right lower bend, vertical left upper tee, vertical right upper tee, etc. The weight of tray and cover plate constitute the main weight of trough type cable tray. For example, the size of ordinary galvanized trough type cable tray is 100 * 50mm, the weight of tray per meter is 3.67kg, and the weight of cover plate per meter is 2.20kg.

槽式電纜橋架吊架編寫提料清單時應填寫：名稱+高度H+橫擔長度L，例如：角鋼雙拉吊架，規格H=1500mm，L=1000mm（角鋼吊架默認橫擔長度=橋架寬度+200mm）。相關標準規定了槽式電纜橋架的耐火等級及其代號，耐火等級代號為N3，維持工作時間大于等于60分鐘。

When preparing the material withdrawal list for trough type cable tray hangers, the following shall be filled in: name+height H+cross arm length L, for example: angle steel double pull hanger, specification H=1500mm, L=1000mm (default cross arm length of angle steel hanger=tray width+200mm). The relevant standards specify the fire resistance rating and its code of the trough type cable tray. The fire resistance rating code is N3, and the maintenance time is no less than 60 minutes.

電纜橋架的常見高度有50mm、100mm、150mm、200mm等。電纜橋架的常見寬度有100mm、200mm、300mm、400mm、500mm、600mm等。在電纜橋架需要分叉敷設或者向上、向下方向延展時，可以設置彎通，因空間條件限制或有特殊要求，可以使用鉸連板。連接不同寬度或高度的兩段電纜橋架時，可以使用變寬或變高連接板。

The common heights of cable tray are 50mm, 100mm, 150mm, 200mm, etc. The common width of cable tray is 100mm, 200mm, 300mm, 400mm, 500mm, 600mm, etc. When the cable tray needs to be bifurcated or extended upward or downward, a bend can be set. Because of space conditions or special requirements, hinged plates can be used. When connecting two cable trays of different widths or heights, you can use a widening or heightening connection plate.

按照標準，連接板的厚度應該與托盤和梯架的厚度保持一致，也可以選厚一個等級，蓋板的厚度可以比橋架板材的厚度低一個等級。規格600x100橋架，按照QB/T 1453-2003標準，橋架厚度應為2.0mm，按照T/CECS 31-2017標準，橋架厚度應為3.0mm。

According to the standard, the thickness of the connecting plate should be consistent with the thickness of the tray and ladder, or a grade of thickness can be selected, and the thickness of the cover plate can be one grade lower than the thickness of the tray plate. The specification of 600x100 cable tray shall be 2.0mm according to QB/T 1453-2003 standard, and 3.0mm according to T/CECS 31-2017 standard.
