大部分桥架都是用钢做的，这就带来了一个不可避免的问题，那就是它自身的重量，简称自重。由于电缆桥架的作用是将电缆固定在桥架内，可以有效保护电缆的安全使用。由于重量过大，在使用过程中会威胁到使用安全，严重影响电线电缆的使用安全和桥架本身的安全。

Most bridges are made of steel, which brings an inevitable problem, that is, its own weight, referred to as self weight. As the function of cable tray is to fix the cable in the tray, it can effectively protect the safe use of the cable. Because the weight is too large, it will threaten the use safety in the process of use, and seriously affect the use safety of wires and cables and the safety of the bridge itself.

所以说要根据不同的使用环境，我们选择的电缆桥架的材质也会有所不同。建筑工程中使用的大多数电缆管道都是由钢制成的。由于铺设距离有限，考虑到电缆桥架的牢固性和支撑性能，钢制电缆桥架在这两方面都有突出表现，尤其是支撑功能，可以为整个施工项目分担部分重力，其牢固性并且使用寿命也有充分保证。

Therefore, the materials of the cable tray we choose will be different according to different use environments. Most cable ducts used in construction projects are made of steel. Due to the limited laying distance, considering the firmness and support performance of the cable tray, the steel cable tray has outstanding performance in these two aspects, especially the support function, which can share part of the gravity for the whole construction project, and its firmness and service life are fully guaranteed.

在轻型运输或管道运输项目中，将使用大跨度电缆桥架作为建筑材料。由于大跨度电缆桥架在设计之初就进行了升级，便于长距离敷设，所以选用的材料多为轻质铝合金材料，重量轻，有一定的承载能力，可以承受使用中的重力和外部压力。在保证长距离电缆的安全方面具有无可比拟的优势。

In light transportation or pipeline transportation projects, long-span cable trays will be used as building materials. Since the long-span cable tray was upgraded at the beginning of design to facilitate long-distance laying, the selected materials are mostly light aluminum alloy materials, which are light in weight, have a certain bearing capacity, and can withstand the gravity and external pressure in use. It has incomparable advantages in ensuring the safety of long-distance cables.

济南电缆桥架厂家认为在使用电缆桥架时，可以因地制宜合理选择电缆桥架的材质，使用效果可以非常满意。当然使用期间不可避免会出现一定的问题，要想顺利使用就要提前了解去预防，比如说常见的问题：

Jinan cable tray manufacturer believes that when using cable tray, the material of cable tray can be reasonably selected according to local conditions, and the use effect can be very satisfactory. Of course, certain problems will inevitably occur during use. If you want to use it smoothly, you must know in advance to prevent it. For example, common problems:

1、整个电缆被烧断或相吹。这种故障导致配电柜上的电流继电器工作，故障中电缆严重损坏。

1. The whole cable is burnt or blown. This fault causes the current relay on the distribution cabinet to work, and the cable is seriously damaged in the fault.

2、电缆的所有相都是短路的。同样，这种故障会导致配电柜上的电流继电器和电压继电器工作，并且电缆在故障点也会严重损坏。

2. All phases of the cable are short circuited. Similarly, this fault will cause the current relay and voltage relay on the distribution cabinet to work, and the cable will be seriously damaged at the fault point.

3、电缆桥只有一相开路，电流继电器动作，故障点损坏较轻但暴露更明显。可能是相电流太大或由电缆质量引起。

3. Only one phase of the cable bridge is open circuit, the current relay acts, and the fault point is slightly damaged but more exposed. It may be caused by excessive phase current or cable quality.

4、电缆内部短路，外观没有看到痕迹，这类故障一般是由电缆质量引起的比较少见。

4. There is a short circuit inside the cable, and no trace is seen on the appearance. This kind of fault is generally caused by the cable quality, which is relatively rare.
