如果需要屏蔽电磁干扰的电缆线路，或有一些具有腐蚀性液体或者易燃粉尘等等的环境要求的时候，我们应该选择无孔托盘式电缆桥架。

　　If the cable lines require shielding electromagnetic interference, or when there are some corrosive liquid or combustible dust and so on environmental requirements, we should choose the non porous tray type cable tray.

　　如果在容易积聚粉尘的场所的时候，对于电缆桥架而言应选用盖板，在公共通道或者室外跨越道路段上应该加上垫板。

　　If while easy to accumulate dust places, for cable tray should be used for the cover, in the public channel or outdoor crossing on a road section should be added to the plate.

　　对于不同电压以及不同用途的电缆不应该敷设在同一层的电缆桥架内，比如说1kV以上和1kV及以下的电缆、电力控制和电信电缆、同一路径向一级负荷供电的双回路电缆以及应急照明和其他照明的电缆。

　　For different purposes and different voltage cable should not be laid in cable tray with one layer, such as 1kV and 1kV above and below the power cable, control cable, telecommunications and the same path to the double loop power cable level load and cable emergency lighting and other lighting.

　　如果不同等级的电缆敷设在同一电缆桥架的时候，在中间应该增加适当的隔板进行有效的隔离。

　　If the cable laying in different levels in the same cable bridge in the middle, we should add an appropriate partition for effective isolation.
