Where is the cable bridge suitable for?

1.電纜橋架適用于普通工礦企業(yè)室內(nèi)外架空敷設(shè)電力電纜、控制電纜，亦可用于電信、播送電視等部門在室內(nèi)外架設(shè)。

1. Cable bridge is suitable for laying power cables and control cables indoors and outdoors in general industrial and mining enterprises, and also for laying indoors and outdoors in telecommunications, broadcasting and television departments.

2.選擇電纜橋架依據(jù)電纜荷載及橋架裝置處的環(huán)境，以電纜橋架的載荷曲線爲(wèi)根據(jù)，來確定電纜橋架的類型和規(guī)格及立柱的間距、托臂的長度、電纜橋架的層次，立柱的長度等。

2. Choosing the cable bridge frame according to the cable load and the environment of the bridge device, and based on the load curve of the cable bridge frame, the types and specifications of the cable bridge frame and the spacing of the columns, the length of the brackets, the layers of the cable bridge frame and the length of the columns are determined.

3.當(dāng)電纜橋架的固定方式采用懸掛式且托臂爲(wèi)單側(cè)多層式裝置時，爲(wèi)了立注受力均衡，應(yīng)選用對材載荷方式，敷設(shè)電纜橋架。

3. When the cable bridge is fixed by hanging type and the bracket is a single-sided multi-layer device, in order to balance the force of the vertical injection, the load mode of the corresponding material should be selected and the cable bridge should be laid.

4.大跨距敷設(shè)電纜，可選用大跨距電纜橋架。

4. For long-span cable laying, long-span cable bridge can be selected.

電纜橋架在穿越易受外來機(jī)械損傷的地域和日曬地域，應(yīng)選用防護(hù)蓋板。當(dāng)電纜槽或桁架式梯架需轉(zhuǎn)變分支時，可采用各種彎通銜接。

Protective covers should be selected for cable bridge traversing areas susceptible to external mechanical damage and sunshine. When cable groove or truss ladder need to change branches, all kinds of bend-through connection can be used.

5.選擇電纜橋架的支撐間距應(yīng)小于允許支撐跨距。寬度應(yīng)留有一定的備用空位，以便當(dāng)前增添電纜用。

5. The support spacing of cable bridge should be less than the allowable support spacing. Width should be reserved for the current addition of cables.

6.電纜橋架的防腐措施爲(wèi)：塑料噴涂、鍍鋅鈍化、電鍍鋅(適用于輕防腐地域)熱浸鍍鋅、熱噴鋅適用于重防腐地域鍍鋅鎳合金等。熱浸鍍鋅電纜橋架用料厚度需添加0．5mm以上。

6. The anticorrosive measures of cable bridge are: plastic spraying, galvanizing passivation, galvanizing (suitable for light anticorrosive areas), hot dipping galvanizing, hot spraying galvanizing for heavy anticorrosive areas, galvanizing nickel alloy, etc. Hot-dip galvanized cable bridge material thickness needs to add more than 0.5mm.
