The bridge is not unfamiliar to some people who build it. It plays an important role in our lives. Only a reasonable and orderly organization can better ensure the safety of all. So how does the cable on Jinan cable bridge have layered arrangement? Next let's do a brief analysis for us.

濟南電纜橋架

Ji'nan cable tray

1.濟南電纜橋架層次擺放應(yīng)是弱電流操控電纜在上層，接著是一般操控電纜，低壓動力電纜、高壓動力電纜依次往下擺放。這種擺放有利于屏蔽干擾、電力電纜冷卻、便于施工。

1. The layers of Jinan cable bridge should be the top layer of weak current control cable, followed by general control cable, low voltage power cable and high voltage power cable in turn. This arrangement is conducive to shielding interference, power cable cooling and easy construction.

2.各層電纜橋架層間的間隔為：

2. the interval between each cable bridge deck is as follows:

操控電纜≥200mm

Control cable is more than 200mm

動力電纜≥300mm

Power cable is more than 300mm

機械化敷設(shè)電纜≥400mm

The mechanized laying cable is more than 400mm

注意事項:

Matters needing attention:

1.XQJ型電纜橋架設(shè)備的大載荷、支撐間隔應(yīng)小于答應(yīng)載荷和支撐跨距。

The maximum load and support interval of 1.XQJ cable bridge equipment should be less than the promised load and supporting span.

2.挑選電纜橋架的寬度時應(yīng)留有必定的備用空位，以便為往后增加電纜用。

2. when selecting the width of the cable tray, there must be a certain reserve space to increase the cable for the future.

3.當(dāng)電力電纜和操控電纜較少時，可用一電纜橋架設(shè)備，但要用隔板將電力電纜和操控電纜離隔敷設(shè)。

3. When there are fewer power cables and control cables, a cable bridge can be used, but the center of the cables and control cables are separated by diaphragms.

4.電纜橋架水平敷設(shè)時，橋架之間的銜接接頭應(yīng)盡量設(shè)置在跨距的1/4左右處.水平走向的電纜每隔2米左右固定一下，垂直走向的電纜每個1.5米左右固定一下。

4. When laying the cable bridge horizontally, the joints between the bridges should be set at about 1/4 of the span as far as possible. Horizontal cable should be fixed every 2 meters, vertical cable should be fixed every 1.5 meters.

5.電纜橋架莊子應(yīng)有牢靠接地。如間隔的電纜橋架每隔30-50米接地一次。

5. cable bridge Chuang-tzu should be firmly grounded. For example, the span of the cable tray will be grounded once every 30-50 meters.

6.電纜橋架設(shè)備除需屏蔽裝保護罩外，在室外設(shè)備時應(yīng)在其加裝保護罩，避免日曬、雨淋。對如需焊接設(shè)備時，焊接四周的焊縫厚度不得小于母材的厚度，焊口有必要防腐處理。

6. In addition to shielding protection cover, cable bridge equipment should be installed on the top of the outdoor equipment to avoid sunshine and rain. If the welding equipment is needed, the thickness of the weld around the welding should not be less than the thickness of the base metal, so it is necessary to treat the weld corrosion.
