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.

槽式电缆桥架产品可以有效的满足工程环进和耐久性的要求，而且电缆桥架的使用，可以有效的保证我们的日常生活，首先槽式电缆桥架及其支吊架以及气动球阀使用在腐蚀环境当中的话，应该采用耐腐蚀的刚性材料制造。

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，电缆桥架在有防火要求的区段内需要采取在桥架及其支吊架表面涂刷防火涂层等措旋，其整体的耐火要求也瞳有关规范或标准的要求。在选择电缆桥架的荷载等级时，电缆桥架的工作均布荷载不能大于所选电缆桥架荷载等级的额定均布荷载。当各种组件及支吊件在满足相应荷载的条件下，其规格尺寸应与托盘、梯架的直线段、弯通系列相匹配。

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.
