Trough type cable trays, abbreviated as trough bridges, are divided into common trough type cable trays and large span trough type cable trays based on their length. The common slot type cable tray is generally 2 meters in length, and the bottom plate and side plate of the cable tray are usually pressed from a single plate.

鍍鋅槽式橋架還可以進行噴涂工藝處理，噴涂防火粉末后就具有了防火阻燃的使用性能，才可以當成防火橋架來用。

Galvanized trough type cable trays can also be treated with spraying technology. After spraying fireproof powder, it has the performance of fire resistance and flame retardancy, and can be used as a fireproof cable tray.

要依據電纜橋架的寬度和高度來進行電纜橋架規格的選用，它取決于電纜橋架內電纜的直徑，電纜的敷設層數，電纜填充率，電纜橋架安裝場所的空間等因素，同時，還要考慮到實際使用的發展余地。

The selection of cable tray specifications should be based on the width and height of the cable tray, which depends on factors such as the diameter of the cable inside the cable tray, the number of layers of cable laying, the cable filling rate, and the space of the cable tray installation site. At the same time, it also needs to consider the development space of actual use.

橋架運輸是指用貨車和叉車，將各種結構、規格、型號、數量的橋架，從廠家的生產車間運輸到客戶在各地的項目工地上去。

Bridge transportation refers to the use of trucks and forklifts to transport various structures, specifications, models, and quantities of bridge structures from the manufacturer's production workshop to customers' project sites across the country.

遇到各種刮風下雨冰雹暴曬天氣的室外橋架，如果是在挨著大海邊上或高腐蝕氣體的外界環境，則材質建議具有防腐（被氧氣侵蝕）、耐潮氣（被水蒸氣腐蝕）。

When encountering various weather conditions such as wind, rain, hail, and exposure to sunlight, outdoor cable trays must be made of corrosion-resistant materials (corroded by oxygen) and moisture (corroded by water vapor) if they are located near the seaside or in an external environment with high corrosive gases.

電纜橋架板材如果使用鍍鋅板材質，對于該材質的要求是外觀要良好，板材表面不能有漏鍍的地方、不能有孔有洞、不能有破爛裂紋的地方或者鋅渣。

If galvanized sheet material is used for cable tray plates, the requirement for this material is to have a good appearance, and the surface of the plate should not have any areas of missed plating, holes, cracks, or zinc slag.

電纜橋架建筑項目要建立日程安排表、財政上的安排、建筑安全、建筑材料的運輸和運用、工程上的延誤、準備投標文件等等。

The cable tray construction project needs to establish a schedule, financial arrangements, building safety, transportation and application of building materials, engineering delays, preparation of bidding documents, and so on.

托盤式橋架具有載荷大（能承受重量沉的東西）造型美觀（結構好看）安裝方便（敷設比較簡單）的特點，是應用范圍廣泛的一種建筑橋架（住宅樓、商業樓等建筑都使用該橋架）。

Tray type cable tray has the characteristics of large load capacity (able to withstand heavy loads), beautiful appearance (beautiful structure), convenient installation (relatively simple laying), and is a widely used building cable tray (used in residential buildings, commercial buildings, and other buildings).

橋架規格決定了配套彎通、三通、四通、變徑直通、變徑三通、連接片的附件規格，也決定了項目中橋架的成本費用多少。

The specifications of the cable tray determine the accessory specifications for supporting bends, tees, crosses, variable diameter straights, variable diameter tees, and connecting pieces, and also determine the cost of the cable tray in the project.

大跨距槽式電纜橋架長短有3米、4米、6米幾種，電纜橋架側板一般采用瓦楞型來增強單位長度內的安全載荷，電纜橋架底板與側板通過焊接固定在一起，電纜橋架廠家生產槽式電纜橋架時通常都采用以上加工工藝。

There are several lengths of large-span trough cable trays, including 3 meters, 4 meters, and 6 meters. The side plates of the cable tray are generally corrugated to enhance the safety load per unit length. The bottom plate and side plate of the cable tray are fixed together by welding. Cable tray manufacturers usually use the above processing technology when producing trough cable trays.
