桥架对于一些修建施工的人来说并不生疏，它在咱们的日子中扮演着比较重要的人物，只要合理有序的组织才干更好的确保全体的。那么济南电缆桥架上的电缆是怎么有层次的摆放的呢?接下来咱们就为我们做简略的剖析。

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.

济南电缆桥架

Ji'nan cable tray

1.济南电缆桥架层次摆放应是弱电流操控电缆在上层，接着是一般操控电缆，低压动力电缆、高压动力电缆依次往下摆放。这种摆放有利于屏蔽干扰、电力电缆冷却、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.各层电缆桥架层间的间隔为：

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

操控电缆≥200mm

Control cable is more than 200mm

动力电缆≥300mm

Power cable is more than 300mm

机械化敷设电缆≥400mm

The mechanized laying cable is more than 400mm

注意事项:

Matters needing attention:

1.XQJ型电缆桥架设备的大载荷、支撑间隔应小于答应载荷和支撑跨距。

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

2.挑选电缆桥架的宽度时应留有必定的备用空位，以便为往后增加电缆用。

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

3.当电力电缆和操控电缆较少时，可用一电缆桥架设备，但中心要用隔板将电力电缆和操控电缆离隔敷设。

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.电缆桥架水平敷设时，桥架之间的衔接接头应尽量设置在跨距的1/4左右处.水平走向的电缆每隔2米左右固定一下，垂直走向的电缆每个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.电缆桥架庄子应有牢靠接地。如间隔的电缆桥架每隔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.电缆桥架设备除需屏蔽装保护罩外，在室外设备时应在其加装保护罩，避免日晒、雨淋。对如需焊接设备时，焊接四周的焊缝厚度不得小于母材的厚度，焊口有必要防腐处理。

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.
