大部分橋架都是用鋼做的，這就帶來了一個不可避免的問題，那就是它自身的重量，簡稱自重。由于電纜橋架的作用是將電纜固定在橋架內(nèi)，可以有效保護電纜的安全使用。由于重量過大，在使用過程中會威脅到使用安全，嚴重影響電線電纜的使用安全和橋架本身的安全。

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.

所以說要根據(jù)不同的使用環(huán)境，我們選擇的電纜橋架的材質(zhì)也會有所不同。建筑工程中使用的大多數(shù)電纜管道都是由鋼制成的。由于鋪設距離有限，考慮到電纜橋架的牢固性和支撐性能，鋼制電纜橋架在這兩方面都有突出表現(xiàn)，尤其是支撐功能，可以為整個施工項目分擔部分重力，其牢固性并且使用壽命也有充分保證。

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.

在輕型運輸或管道運輸項目中，將使用大跨度電纜橋架作為建筑材料。由于大跨度電纜橋架在設計之初就進行了升級，便于長距離敷設，所以選用的材料多為輕質(zhì)鋁合金材料，重量輕，有一定的承載能力，可以承受使用中的重力和外部壓力。在保證長距離電纜的安全方面具有無可比擬的優(yōu)勢。

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.

濟南電纜橋架廠家認為在使用電纜橋架時，可以因地制宜合理選擇電纜橋架的材質(zhì)，使用效果可以非常滿意。當然使用期間不可避免會出現(xiàn)一定的問題，要想順利使用就要提前了解去預防，比如說常見的問題：

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、整個電纜被燒斷或相吹。這種故障導致配電柜上的電流繼電器工作，故障中電纜嚴重損壞。

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、電纜的所有相都是短路的。同樣，這種故障會導致配電柜上的電流繼電器和電壓繼電器工作，并且電纜在故障點也會嚴重損壞。

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、電纜橋只有一相開路，電流繼電器動作，故障點損壞較輕但暴露更明顯。可能是相電流太大或由電纜質(zhì)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、電纜內(nèi)部短路，外觀沒有看到痕跡，這類故障一般是由電纜質(zhì)量引起的比較少見。

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.
