The cable tray is made of thin steel sheet, with limited load capacity and deformation due to overload of bridge. It not only affects the appearance of the bridge, but also affects the safe operation of the cable.

　　通常情况下，电缆桥架的承载能力是用电缆桥架的载荷特性曲线表示的，从载荷曲线图可以看出，其载荷能力大小是与桥架规格和支撑距离有关，对应于同一支撑距离和弯凸变形量。

　　Usually, the carrying capacity of the cable tray is expressed by the load characteristic curve of the cable tray. It can be seen from the load graph that the load capacity is related to the bridge specifications and supporting distance, corresponding to the same support distance and bending deformation.

　　侧面高度大，承载力大，当载荷能力相同时，同一规格的电缆桥架的支撑距离小的弯曲变形量小。

　　The side height is large and the bearing capacity is large. When the load capacity is at the same time, the supporting distance of the same cable bridge is small, and the bending deformation is small.

　　槽式电缆桥架是一种全封闭型的电缆桥架，由于它可以有效的控制电缆的屏蔽干扰，同时在重腐蚀的环境中对电缆的防护都有较好的效果，所以，它适用于敷设计算机电缆、热电偶电缆、通信电缆以及其他高灵敏系统中去控制电缆等，不得不说，在槽式的汇线桥架中的防尘以及防干扰性能是十分的突出的一个优点和特点。

　　Trough cable tray type cable tray is a fully closed, because it can control cable shielding interference effectively, at the same time in the environment of heavy corrosion protection of the cable has good effect, so it is most suitable for laying computer cables, thermocouple cables, communication cables and other sensitive systems. Control cables, have to say, the dust in the trough of the cable tray and the anti jamming performance is very prominent advantages and characteristics of A.
