Before using the product, we should first choose the appropriate product, then how to choose the trough cable tray, what are the selection points? Let's understand the selection of trough cable tray.

槽式電纜橋架產品可以有效的滿足工程環進和耐久性的要求，而且電纜橋架的使用，可以有效的保證我們的日常生活，首先槽式電纜橋架及其支吊架以及氣動球閥使用在腐蝕環境當中的話，應該采用耐腐蝕的剛性材料制造。

Trough type cable tray products can effectively meet the requirements of engineering environment and durability, and the use of cable tray can effectively ensure our daily life. First of all, if trough type cable tray and its supports and hangers as well as pneumatic ball valve are used in corrosive environment, they should be made of corrosion-resistant rigid materials.
                     

此外，電纜橋架在有防火要求的區段內需要采取在橋架及其支吊架表面涂刷防火涂層等措旋，其整體的耐火要求也瞳國家有關規范或標準的要求。在選擇電纜橋架的荷載等級時，電纜橋架的工作均布荷載不能大于所選電纜橋架荷載等級的額定均布荷載。當各種組件及支吊件在滿足相應荷載的條件下，其規格尺寸應與托盤、梯架的直線段、彎通系列相匹配。

In addition, in the section with fire protection requirements, the cable tray and its supports and hangers need to be coated with fire protection coating, and the overall fire resistance requirements are in line with the requirements of relevant national codes or standards. When selecting the load level of cable tray, the working uniform load of cable tray shall not be greater than the rated uniform load of the selected load level of cable tray. When all kinds of components and supporting and hanging parts meet the corresponding load conditions, their specifications and dimensions shall match the straight section and bend through series of pallets and ladders.
