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.

電纜橋架在使用中比較常見的問題就是短路，短路可能是電纜內部短路也可能是電纜被燒斷等原因，總體來說就是電纜質量過低導致。電纜橋架在使用過程中還會出現脹縮的問題，由于環境溫度的變化，像是鋼制電纜橋架就會出現熱脹冷縮的現象，室外橋架的作用受溫度影響是比較大的，因此使用中要注意高溫風機溫度的變化才行。

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.

電纜橋架在使用中還需要找準型號按照相關規定進行使用，不同類型的電纜橋架應用范圍是不同的，要按照自己的需求來找尋合適的橋架使用。切不可盲目選擇使用，這樣不僅不能保障使用的效果，還會縮短橋架的使用壽命。

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.
