Trough type cable tray

槽式電纜橋架與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。封閉的槽盒、無(wú)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(hù)性以槽式好、梯架差，但通風(fēng)冷卻性卻相反。

Both trough type cable trays and tray type cable trays can be used for laying power cables; The cross-section and structural form are different. 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 good protective performance in the trough and poor ladder, but opposite ventilation and cooling performance.

槽式電纜橋架的優(yōu)勢(shì)在于屏蔽和防腐，主要適用于鋪設(shè)截面小但是數(shù)量卻非常多的電線電纜；而托盤式纜橋架優(yōu)勢(shì)在于載荷大和散熱好，主要就是用于鋪設(shè)截面大但是數(shù)量比較小的電力電纜。

The advantages of trough type cable trays lie in shielding and anti-corrosion, mainly suitable for laying wires and cables with small cross-section but a large quantity; The advantages of tray type cable trays lie in their large load and good heat dissipation, mainly used for laying power cables with large cross-section but relatively small quantity.

從外形來(lái)看，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。

From the appearance, the trough 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.

橋架：跨接表識(shí)，彎曲度一致

Cable tray: cross connection surface recognition, consistent bending degree

▲ 橋架跨接線連接要注意：用抓墊、平墊或把噴塑橋架的漆刮掉再用平墊、彈簧墊壓緊。鍍鋅電纜橋架間連接板的兩端不跨接接地線，但連接板兩端不少于2個(gè)有防松螺帽或防松墊圈的連接固定螺栓（強(qiáng)標(biāo)） 。于支架的接地，就是把支架與橋架連接處固定刮漆就可以（或是抓墊）。接地線小截面不小于4。

▲ Attention should be paid to the bridge jumper connection: use grab pads, flat pads, or scrape off the paint of the spray molded bridge before pressing it tightly with flat pads or spring pads. The two ends of the connecting plate between galvanized cable trays shall not be connected to the grounding wire, but there shall be no less than two connection fixing bolts (strong standard) with locking nuts or washers at both ends of the connecting plate. As for the grounding of the bracket, it is necessary to fix and paint the connection between the bracket and the bridge (or to grab a pad). The small cross-section of the grounding wire shall not be less than 4 square meters.

▲ 金屬電纜橋架及其支架全長(zhǎng)應(yīng)不少于2處與接地（PE）或接零（PEN）干線相連接；

The total length of the metal cable tray and its bracket should not be less than 2 places connected to the grounding (PE) or neutral (PEN) main line;

▲ 跨接線壓線處細(xì)部做法：

▲ Detailed practice at the crimping point of the jumper wire:

注意墊片及順序及螺栓外露的長(zhǎng)度及接識(shí)、螺栓的位置；不能用連接螺栓固定跨接線。

Pay attention to the gasket and sequence, as well as the exposed length of bolts, grounding markings, and bolt positions; Do not use connecting bolts to secure jumper wires.

▲ 橋架的安裝：橫平豎直，彎頭處要平緩。當(dāng)橋架分層時(shí)，好用組合架。

Installation of cable tray: Horizontal and vertical, with gentle bends. When the bridge is layered, it is easy to use a combination frame.

▲ 橋架內(nèi)部要加設(shè)防火封堵或加設(shè)防火包。

Fire blocking or fire protection bags should be installed inside the bridge.

▲ 鋼制30米，鋁合金及塑料的15米要加伸縮節(jié)。過建筑物變形縫處（伸縮縫、沉降縫）加補(bǔ)償裝置。

Steel 30 meters, aluminum alloy and plastic 15 meters require expansion joints. Install compensation devices at the deformation joints (expansion joints, settlement joints) of the building.

▲ 橋架的支架間距一般要求水平的為1.5-3米，垂直的為2米一個(gè)。

The spacing between the supports of the cable tray is generally required to be 1.5 to 3 meters horizontally and 2 meters vertically.

▲ 螺母位于橋架的外側(cè)。當(dāng)支架與鋁合金橋架連接時(shí)，注意防電化措施。

The nut is located on the outer side of the bridge. When connecting the bracket to the aluminum alloy bridge, pay attention to anti electrochemical measures.

▲ 注意轉(zhuǎn)彎處支架的設(shè)置。

▲ Pay attention to the setting of brackets at turns.

▲ 配電室大型橋架要采用可調(diào)式組合支架 大型工程橋架彎曲度要一致。

▲ The large cable tray in the distribution room should use adjustable combination brackets, and the bending degree of the large engineering cable tray should be consistent.

托盤式橋架

cable tray 

1、槽式電纜橋架主要特點(diǎn)是屏蔽干擾，抗腐蝕，防火，對(duì)控制電纜屏蔽干擾和重腐蝕環(huán)境中電纜的防護(hù)都有較好效果，對(duì)控制電纜屏蔽干擾和重腐蝕環(huán)境中電纜的防護(hù)都有較好效果。適用于敷設(shè)計(jì)算機(jī)電纜、通信電纜、熱電偶電纜及高靈敏系統(tǒng)的控制電纜等。用于敷設(shè)截面小但數(shù)量多的電線電纜。這也是弱電工程中經(jīng)濟(jì)實(shí)用的一種橋架。

1. The main characteristics of trough type cable trays are shielding interference, corrosion resistance, and fire prevention. They have good effects on controlling cable shielding interference and protecting cables in heavily corrosive environments. They also have good effects on controlling cable shielding interference and protecting cables in heavily corrosive environments. Suitable for laying computer cables, communication cables, thermocouple cables, and control cables for highly sensitive systems. Used for laying wires and cables with a small cross-section but a large quantity. This is also an economical and practical cable tray in weak current engineering.

2、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，防火和抗腐蝕性能要相對(duì)差一些，在重腐蝕環(huán)境中必須作特殊的防腐處理。托盤橋架底部有很多腰形孔，以利于散熱，重量輕、載荷大，主要用于敷設(shè)截面大數(shù)量較少的電力電纜。

2. The surface treatment of tray type cable trays can be divided into three types according to user needs: galvanizing, electrostatic spraying, and hot galvanizing. The fire and corrosion resistance performance is relatively poor, and special anti-corrosion treatment must be carried out in heavily corrosive environments. There are many waist shaped holes at the bottom of the tray tray to facilitate heat dissipation. It is lightweight and has a large load, and is mainly used for laying power cables with a large cross-section and a small quantity.

鍍鋅橋架和熱鍍鋅橋架

Galvanized and hot-dip galvanized cable trays

很多人以為鍍鋅橋架就是熱鍍鋅橋架，其實(shí)是錯(cuò)誤的，鍍鋅橋架不等于熱鍍鋅橋架。

Many people think that galvanized cable trays are hot-dip galvanized cable trays, but it is actually a mistake. Galvanized cable trays are not equivalent to hot-dip galvanized cable trays.

熱鍍鋅橋架又可分為“熱浸鋅”和“熱鍍鋅”兩種，鍍鋅就是“冷鍍鋅”或“電鍍鋅”。

Hot dip galvanized cable trays can be divided into two types: "hot dip galvanizing" and "hot dip galvanizing", with galvanizing being either "cold galvanizing" or "electro galvanizing".

鍍鋅橋架是用“冷鍍鋅板”制造而成，而熱鍍鋅橋架是用冷鍍鋅橋架經(jīng)過表面處理浸鋅一層熱鍍鋅制造而成，制造工藝不同。

Galvanized cable trays are made of "cold galvanized sheet", while hot-dip galvanized cable trays are made of a layer of hot-dip galvanizing after surface treatment, with different manufacturing processes.

冷鍍鋅橋架的冷鍍鋅鋅層較熱鍍光亮，但較薄，抗銹蝕能力較弱。

The cold galvanized zinc layer of the cold galvanized bridge is brighter than that of the hot galvanizing, but it is thinner and has weaker rust resistance.

熱鍍鋅橋架熱鍍鋅鍍層較厚，抗侵蝕能力較強(qiáng)。比鍍鋅橋架的壽命要長(zhǎng)，無(wú)論是硬度還是耐沖擊，熱鍍鋅是占優(yōu)勢(shì)的。當(dāng)然熱鍍鋅橋架的成本較高。

The hot-dip galvanized coating on the bridge is thick and has strong corrosion resistance. Compared to galvanized cable trays, hot-dip galvanizing has an absolute advantage in terms of hardness and impact resistance. Of course, the cost of hot-dip galvanized cable trays is higher.

通常在工程應(yīng)用的鍍鋅電纜橋架，其實(shí)就是冷鍍鋅橋架，因?yàn)闊徨冧\橋架制作成本較貴，廠家很少會(huì)堆積庫(kù)存的，施工要求較高的工地會(huì)用到熱鍍鋅橋架，客戶去采購(gòu)指定要“熱鍍鋅橋架”，廠家才會(huì)生產(chǎn)定制。

The commonly used galvanized cable trays in engineering applications are actually cold galvanized trays. Due to the high production cost of hot-dip galvanized trays, manufacturers rarely accumulate inventory. Construction sites with high construction requirements will use hot-dip galvanized trays, and customers will purchase and specify "hot-dip galvanized trays" before the factory can produce customized ones.

鋁合金橋架

Aluminum alloy bridge

鋁合金電纜橋架具有外觀漂亮、結(jié)構(gòu)簡(jiǎn)單、式樣獨(dú)特、荷載能力大、重量輕等特點(diǎn)。鋁合金電纜橋架表面陽(yáng)極氧化后，它不但抗腐蝕、還有抗電磁干擾，尤其是抗屏蔽干擾，這是鋼制橋架不可替代的。當(dāng)然也較鋼制橋架高很多。

Aluminum alloy cable trays have the characteristics of beautiful appearance, simple structure, unique style, large load capacity, and light weight. After anodizing the surface of aluminum alloy cable trays, they not only resist corrosion but also electromagnetic interference, especially shielding interference, which is irreplaceable for steel cable trays. Of course, the price is also much higher than that of steel cable trays.

缺點(diǎn)是不適用于工程防火要求較高的場(chǎng)所。

The disadvantage is that it is not suitable for places with high engineering fire protection requirements.

網(wǎng)格式橋架

Grid format cable tray

開放式網(wǎng)絡(luò)橋架顧名思義又稱為：金屬網(wǎng)格式電纜橋架，開放式電纜橋架，網(wǎng)狀橋架。網(wǎng)格式橋架來(lái)源于歐洲，是橋架的發(fā)展和創(chuàng)新，由于網(wǎng)格式的特點(diǎn)，網(wǎng)格式橋架不適用于室外或有污染腐蝕性的空氣及飛濺液體的場(chǎng)合；適用于常見于高集成的數(shù)據(jù)機(jī)房、無(wú)塵車間、設(shè)備內(nèi)外的通信、電氣線路等……

Open network cable tray, as the name suggests, is also known as metal mesh cable tray, open cable tray, and mesh cable tray. The grid format bridge comes from Europe and is a development and innovation of the bridge. Due to the characteristics of the grid format, the grid format bridge is not suitable for outdoor or occasions with polluted and corrosive air and splashing liquids; Suitable for commonly used in highly integrated data rooms, dust-free workshops, communication inside and outside equipment, electrical circuits, etc

When selecting the load level of the cable tray, the working uniform load of the cable tray should not exceed the rated uniform load of the selected cable tray load level. If the actual span of the support and hanger of the cable tray is not equal to 2 meters, the working uniform load should meet the requirements. Under the conditions of meeting corresponding loads, the specifications and dimensions of various components and supports and hangers should match the straight section and bending series of trays and ladders.
