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.

托盤式電纜橋架具有重理輕、載荷大、造型美觀、結(jié)構(gòu)簡單、安裝方便等優(yōu)點。它既適用于動力電纜的安裝，也透用于控制電纜的敷設(shè)。托盤式電纜橋架其表面處理分為鍍和噴漆兩種，在重腐蝕環(huán)境中可特殊防腐處理。托盤式電纜橋架備有護罩，所有配件與托盤式、槽式橋架通用。

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.

托盤式電纜橋架根據(jù)結(jié)構(gòu)可分為：有孔托盤、無孔托盤和組裝式托盤。

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

（1）有孔托盤是由帶孔眼的底板和側(cè)板所組成的槽形部件，或由整塊鋼板沖孔后彎制成的部件。

(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）無孔托盤是由底板與側(cè)邊構(gòu)成的或由整塊鋼板制成的槽型部件。

(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）組裝式托盤是由適于工程現(xiàn)場任意組合的有孔部件用螺栓或插接方式連接成托盤的部件。

(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.

他們都是用來敷設(shè)電纜的，低壓電纜和控制電纜共用同一托盤或梯架時，應(yīng)選用中間設(shè)置隔板的梯架或托盤。

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、槽式電纜橋架與無孔托盤式電纜橋架是同一種產(chǎn)品嗎？

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

2、槽式電纜橋架與無孔托盤式電纜橋架是不是都可以敷設(shè)電力電纜？

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

槽式直通電纜橋架與無孔托盤式電纜橋架是都可以敷設(shè)電力電纜；斷面、結(jié)構(gòu)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.

封閉的槽盒、無蓋的托盤還有梯架都屬于電纜橋架，三種橋架的結(jié)構(gòu)形式不同，一些性能也有差異，比如防護性以槽式好、梯架差，但通風(fēng)冷卻性卻相反。

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.

槽式橋架與托盤式電纜橋架的區(qū)別（使用）

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

槽式電纜橋架主要用于敷設(shè)截面小但數(shù)量多的電線電纜。托盤式纜橋架主要用于敷設(shè)截面大數(shù)量較少的電力電纜。

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.

槽式橋架適用于敷設(shè)計算機電纜、通信電纜、熱電偶電纜及其槽式橋架高靈敏系統(tǒng)的控制電纜等。

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.

托盤式橋架適用范圍托盤式電纜橋架是石油、化工、輕工、電視、電訊等方面應(yīng)用廣泛的一種。

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

槽式橋架一般儀表用的多，電氣橋架一般多用梯式橋架和托盤式橋架。其中動力電纜一般只用梯架式橋架。托盤式橋架一般用于控制電纜的敷設(shè)。主要是依據(jù)電纜散熱性能。

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.

槽式橋架與托盤式電纜橋架的區(qū)別（外形）

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

槽式電纜橋架是一種全封閉型電纜橋架。托盤橋架一般指的是有孔的槽式橋架。由于開了散熱孔，托盤式橋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.

槽式橋架與托盤式電纜橋架的區(qū)別（性能）

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

槽式橋架是360度全封閉的，主要功能是屏蔽干擾，抗腐蝕，對控制電纜屏蔽干擾和重腐蝕環(huán)境中電纜的防護都有較好效果。

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.

托盤式橋架其表面處理可根據(jù)用戶需要可分為鍍鋅、靜電噴塑和熱鍍鋅三種，在重腐蝕環(huán)境中可作特殊防腐處理。

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.

托盤橋架底部有很多腰形孔，以利于散熱。

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