托盤式電纜橋架是石油、化工、電力、輕工、電視、電訊等方面應(yīng)用廣泛的一種。它具有重量輕，載荷大，造型美觀、結(jié)構(gòu)簡(jiǎn)單，安裝方便等優(yōu)點(diǎn)，它既適用于動(dòng)力電纜的安裝，也適用于控制電纜的敷設(shè)。

Tray type cable tray is the most widely used one in petroleum, chemical industry, electric power, light industry, television, telecommunications, etc. It has 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.

濟(jì)南橋架廠家提醒，其表面處理可根據(jù)用戶需要分為鍍鋅、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。

Jinan bridge manufacturer reminds that its surface treatment 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.

施工安裝要點(diǎn)：

Key points of construction and installation:

1)電纜橋架及線槽敷設(shè)走向應(yīng)短捷，并應(yīng)盡量沿墻、沿柱或沿梁敷設(shè)。

1) The laying direction of cable tray and trunking shall be short, and shall be laid along the wall, column or beam as far as possible.

2)根據(jù)電纜橋架及線槽敷設(shè)走向，向土建、結(jié)構(gòu)提出預(yù)留墻洞、樓板洞及吊架安裝時(shí)，所需預(yù)埋鋼板位置及荷載。并且應(yīng)與工藝、水暖及動(dòng)力相協(xié)調(diào)。

2) According to the laying direction of cable tray and trunking, the position and load of the embedded steel plate required for the installation of reserved wall holes, floor holes and hangers are proposed to the civil engineering and structural disciplines. And it should be coordinated with the craft profession, plumbing profession, and power profession.

3)地面內(nèi)暗裝金屬線槽布線，在設(shè)計(jì)時(shí)應(yīng)與土建密切配合，以便根據(jù)不同的結(jié)構(gòu)型式和建筑布局，合理確定線路路徑和設(shè)備選型。

3) Concealed metal trunking wiring on the ground should be designed in close coordination with the civil engineering profession, in order to reasonably determine the route and equipment selection based on different structural types and building layouts.

4)不同電壓、不同用途的電纜不宜敷設(shè)在同一層電纜橋架內(nèi):

4) Cables with different voltages and different purposes should not be laid in the same cable tray:

1kV以上和1kV及以下的電纜;

Cables above 1kV and below 1kV;

同一路徑向一級(jí)負(fù)荷供電的雙回路電纜;

Double circuit cables supplying power to primary loads along the same path;

應(yīng)急照明和其他照明的電纜;

Emergency lighting and other lighting cables;

電力、控制和電信電纜。若不同等級(jí)的電纜敷設(shè)在同一電纜橋架時(shí)，中間應(yīng)增加隔板隔離。

Power, control, and telecommunications cables. If cables of different grades are laid on the same cable tray, partition separation shall be added in the middle.

5)在工程條件下安裝或檢修不需考慮附加集中荷載時(shí)，電纜梯架、托盤的工作均布荷載按電纜自重均勻分布計(jì)算。

5) When installation or maintenance under engineering conditions do not require the consideration of additional concentrated loads, the working uniform load of cable ladders and trays is calculated based on the uniform distribution of the cable's own weight.

6)電纜橋架不宜與下列管道平行敷設(shè)，當(dāng)無法避免時(shí)，電纜橋架的位置應(yīng)符合下列規(guī)定，或采取相應(yīng)防護(hù)措施。

6) The cable tray should not be laid in parallel with the following pipes. If it is unavoidable, the position of cable tray should comply with the following provisions, or take corresponding protective measures.

電纜橋架應(yīng)在具有腐蝕性液體管道上方。

The cable tray shall be above the pipeline with corrosive liquid.

電纜橋架應(yīng)在熱力管道下方。

The cable tray shall be under the heating pipe.

易燃易爆氣體比空氣重時(shí)，電纜橋架應(yīng)在管道上方。

When flammable and explosive gas is heavier than air, cable tray shall be above the pipeline.

易燃易爆氣體比空氣輕時(shí)，電纜橋架應(yīng)在管道下方。

When flammable and explosive gas is lighter than air, cable tray shall be under the pipeline.

7)電纜橋架與管道之間小距離見相關(guān)標(biāo)準(zhǔn)。

7) See relevant standards for the small distance between cable tray and pipeline.

8)綜合布線電纜與附近可能產(chǎn)生高電平電磁干擾的電動(dòng)機(jī)、電力變壓器等電氣設(shè)備之間應(yīng)保持必要的間距。

8) Necessary spacing should be maintained between the comprehensive wiring cable and nearby electrical equipment such as motors, power transformers, which may generate high-level electromagnetic interference.

9)墻上敷設(shè)的綜合布線電纜、光纜及管線與其它管線的間距應(yīng)符合GB/T50311-2000規(guī)范11.0.2條的規(guī)定。

9) The spacing between the integrated wiring cables, optical cables, and pipelines laid on the wall and other pipelines should comply with the provisions of Article 11.0.2 of GB/T50311-2000.

10)電纜橋架水平敷設(shè)時(shí)，宜按荷載曲線選取跨距進(jìn)行支撐，跨距一般為1.5~3.0m。垂直敷設(shè)時(shí)，其固定間距不宜大于2m。

10) When cable tray is laid horizontally, the span should be selected for support according to the load curve, and the span is generally 1.5~3.0m. When laying vertically, the fixed spacing should not exceed 2m.

此外您要知道，托盤式電纜橋架可備護(hù)罩，需要配護(hù)罩時(shí)可在訂貨時(shí)注明，其所有配件與梯級(jí)式，槽式橋架通用。還有什么疑惑或者需求，就來我們網(wǎng)站http://m.ymmgjx.net咨詢吧！
