Tray type cable tray has the advantages of light weight, large load, beautiful appearance, simple structure, convenient installation, etc. It is suitable for both the installation of power cables and the laying of control cables. The surface treatment of tray type cable tray can be divided into plating and painting, and special anti-corrosion treatment can be carried out in heavily corrosive environment. Tray type cable tray is equipped with shield, and all accessories are common to tray type and trough 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。

According to the structure, tray type cable tray can be divided into perforated tray, non perforated tray and assembled tray.

（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.

1、槽式电缆桥架与无孔托盘式电缆桥架是同一种产品吗？

1. Is the trough type cable tray the same product as the hole free tray type cable tray?

2、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？

2. Can both trough type cable tray and non hole tray type cable tray lay 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 straight through cable tray and non hole tray type cable tray can lay power cables; The cross-section and structural form are 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。

The closed tray box, uncovered tray and ladder are all cable tray. The three types of cable tray have different structural forms and different performances. For example, the channel type has the best protection and the ladder is the worst, but the ventilation and cooling are opposite.
