The tray type cable tray has the advantages of heavy handling, light load, large appearance, simple structure, and convenient installation. It is suitable for both the installation of power cables and the laying of control cables. The surface treatment of tray type cable trays can be divided into two types: plating and painting, and special anti-corrosion treatment can be applied in heavily corrosive environments. The tray type cable tray is equipped with a cover, and all accessories are common to the tray type slot type cable tray.

托盘式电缆桥架根据结构可分为：有孔托盘无孔托盘和组装式托盘。

Tray type cable trays can be divided into perforated trays, non perforated trays, and assembled trays based on their structure.

（1）有孔托盘是由带孔眼的底板和侧板所组成的槽形部件，或由整块钢板冲孔后弯制成的部件。

(1) A perforated tray is a groove shaped component composed of a bottom plate and a side plate with holes, or a component made by punching and bending a whole steel plate.

（2）无孔托盘是由底板与侧边构成的或由整块钢板制成的槽型部件。

(2) A perforated tray is a groove shaped component composed of a bottom plate and side edges or made of an entire steel plate.

（3）组装式托盘是由适于工程现场任意组合的有孔部件用螺栓或插接方式连接成托盘的部件。

(3) Assembled pallets are components that are connected to a pallet by bolts or plugs, which are suitable for any combination of perforated components on the engineering site.

他们都是用来敷设电缆的，低压电缆和控制电缆共用同一托盘或梯架时，应选用中间设置隔板的梯架或托盘。

They are all used for laying cables. When low-voltage cables and control cables share the same tray or ladder, a ladder or tray with a partition in the middle should be selected.

槽式电缆桥架与无孔托盘式电缆桥架是同一种产品吗？

Are slot type cable trays and perforated tray type cable trays the same product?

槽式电缆桥架与无孔托盘式电缆桥架是不是都可以敷设电力电缆？

Can both slot type cable trays and perforated tray type cable trays be used for laying power cables?

槽式直通电缆桥架与无孔托盘式电缆桥架是都可以敷设电力电缆；断面结构形式不同而已。

Both trough type through cable trays and perforated tray type cable trays can be used for laying power cables; The cross-sectional structure is just different.

封闭的槽盒无盖的托盘还有梯架都属于电缆桥架，三种桥架的结构形式不同，一些性能也有差异，比如防护性以槽式好梯架差，但通风冷却性却相反。

Closed trays, uncovered trays, and ladders all belong to cable trays. The three types of trays have different structural forms and some performance differences. For example, the best protection is the trough type, while the worst is the ladder, but the opposite is true for ventilation and cooling.
