In the process of using cable tray, we may encounter many problems. Now we just need to look at the relevant instructions about the short circuit and model selection of cable tray in use.

电缆桥架在使用中比较常见的问题就是短路，短路可能是电缆内部短路也可能是电缆被烧断等原因，总体来说就是电缆质量过低导致。电缆桥架在使用过程中还会出现胀缩的问题，由于环境温度的变化，像是钢制电缆桥架就会出现热胀冷缩的现象，室外桥架的作用受温度影响是比较大的，因此使用中要注意高温风机温度的变化才行。

The common problem of cable tray in use is short circuit. Short circuit may be caused by internal short circuit of cable or cable burning. Generally, it is caused by low cable quality. The cable tray will expand and shrink during use. Due to the change of ambient temperature, for example, the steel cable tray will expand with heat and contract with cold. The effect of outdoor cable tray is greatly affected by temperature. Therefore, attention should be paid to the change of high temperature fan temperature during use.

电缆桥架在使用中还需要找准型号按照相关规定进行使用，不同类型的电缆桥架应用范围是不同的，要按照自己的需求来找寻合适的桥架使用。切不可盲目选择使用，这样不仅不能保障使用的效果，还会缩短桥架的使用寿命。

In the use of cable tray, the model should be determined according to relevant regulations. Different types of cable tray have different application ranges, so it is necessary to find the appropriate cable tray according to your own needs. It is not allowed to use the cable tray blindly. This will not only not ensure the use effect, but also shorten the service life of the cable tray.
