Select cable tray according to cable load and environment cable tray installation, load curve of cable tray, determine cable tray type and specification, column spacing, arm length, cable tray, column length, etc.

　　当电缆桥架固定方式为悬索式，支撑臂为单侧多层安装时，为了平衡垂直喷射的应力，应选择材料加载方式敷设电缆桥架。

　　In order to balance the stress of vertical spray, the material loading method should be selected to lay the cable bridge when the cable bridge is fixed in the form of suspension and the support arm is installed in one side and multiple layers.

　　大跨度电缆敷设，可选用大跨度电缆桥架。

　　For long-span cable laying, long-span cable tray can be selected.

　　当电缆桥架通过易受外部机械损伤的区域和暴露在阳光下的区域时，应选择防护罩板。当电缆槽或桁架式梯子需要切换支路时，可采用各种弯通连接方式。

　　When the cable tray passes through the area vulnerable to external mechanical damage and the area exposed to sunlight, the protective cover plate shall be selected. When the cable trough or truss ladder needs to switch the branch, it can adopt various bending connection methods.

　　所选电缆桥架的支撑间距应小于允许的支撑间距。宽度要留有一定的空间，以便以后添加电缆。

　　The support spacing of the selected cable tray shall be less than the allowable support spacing. The width should allow some space for adding cables later.

　　电缆桥架的防腐措施有:喷塑、镀锌钝化、电镀锌(适用于轻防腐部位)、热浸镀锌、热喷锌(适用于重防腐部位)、镀锌镍合金等。热镀锌电缆桥架厚度增加0.5mm以上。

　　The anti-corrosion measures for cable tray include: plastic spraying, galvanizing passivation, electro galvanizing (applicable to light anti-corrosion parts), hot-dip galvanizing, hot-dip galvanizing (applicable to heavy anti-corrosion parts), galvanized nickel alloy, etc. The thickness of hot-dip galvanized cable tray is increased by more than 0.5mm.
