Cable tray is a rigid structural system consisting of straight sections, bends, components, and support arms (arm brackets), hangers, etc. of the tray, which have tightly connected supporting cables.

托盘式电缆桥架具有重理轻、载荷大、造型美观、结构简单、安装方便等优点。它既适用于动力电缆的安装，也透用于控制电缆的敷设。托盘式电缆桥架其表面处理分为镀和喷漆两种，在重腐蚀环境中可特殊防腐处理。托盘式电缆桥架备有护罩，所有配件与托盘式、槽式桥架通用。

Tray type cable trays have the advantages of light weight, large load, beautiful 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. Tray type cable trays are equipped with protective covers, and all accessories are common to tray and trough type cable trays.

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, 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.

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

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 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-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。

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

槽式桥架与托盘式电缆桥架的区别（使用）

The difference between slot type cable tray and tray type cable tray (use)

槽式电缆桥架主要用于敷设截面小但数量多的电线电缆。托盘式缆桥架主要用于敷设截面大数量较少的电力电缆。

Slot type cable trays are mainly used for laying wires and cables with a small cross-section but a large quantity. Tray type cable trays are mainly used for laying power cables with a large cross-section and a small quantity.

槽式桥架适用于敷设计算机电缆、通信电缆、热电偶电缆及其槽式桥架高灵敏系统的控制电缆等。

Slot type cable trays are most suitable for laying computer cables, communication cables, thermocouple cables, and control cables for highly sensitive systems in slot type cable trays.

托盘式桥架适用范围托盘式电缆桥架是石油、化工、轻工、电视、电讯等方面应用广泛的一种。

Tray type cable tray is the most widely used type in petroleum, chemical, light industry, television, telecommunications, and other fields.

槽式桥架一般仪表用的多，电气桥架一般多用梯式桥架和托盘式桥架。其中动力电缆一般只用梯架式桥架。托盘式桥架一般用于控制电缆的敷设。主要是依据电缆散热性能。

Slot type cable trays are commonly used for instruments, while ladder type and tray type cable trays are commonly used for electrical cables. Among them, power cables generally only use ladder type cable trays. Tray type cable trays are generally used for laying control cables. Mainly based on the heat dissipation performance of the cable.

槽式桥架与托盘式电缆桥架的区别（外形）

The difference between slot type cable tray and tray type cable tray (appearance)

槽式电缆桥架是一种全封闭型电缆桥架。托盘桥架一般指的是有孔的槽式桥架。由于开了散热孔，托盘式桥架板材的厚度要更厚些。

Slot type cable tray is a fully enclosed cable tray. Tray trays generally refer to slotted trays with holes. Due to the opening of heat dissipation holes, the thickness of the tray type bridge board is thicker.

槽式桥架与托盘式电缆桥架的区别（性能）

The difference between slot type cable tray and tray type cable tray (performance)

槽式桥架是360度全封闭的，主要功能是屏蔽干扰，抗腐蚀，对控制电缆屏蔽干扰和重腐蚀环境中电缆的防护都有较好效果。

The trough type cable tray is a 360 degree fully enclosed structure, with the main function of shielding interference and resisting corrosion. It has good effects on controlling cable shielding interference and protecting cables in heavily corrosive environments.

托盘式桥架其表面处理可根据用户需要可分为镀锌、静电喷塑和热镀锌三种，在重腐蚀环境中可作特殊防腐处理。

The surface treatment of tray type cable trays can be divided into three types according to user needs: galvanizing, electrostatic spraying, and hot galvanizing. In heavily corrosive environments, special anti-corrosion treatment can be applied.

托盘桥架底部有很多腰形孔，以利于散热。

There are many waist shaped holes at the bottom of the tray tray to facilitate heat dissipation.
