As an intelligent weak current system, bridge plays an important role in our daily life. But its usual will also present problems, to our life form confusion. What are the problems of cable tray?

鍍鋅噴塑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，毛病處電纜損壞較輕，但還是會有很明顯的痕跡。會呈現的原因在于電流太大或許電纜質量太差而形成的。總體來說就是電纜質量過低導致,外表上不會流露痕跡;這類毛病可能會形成配電柜上的電流繼電器作業，對橋架形成的損壞十分嚴峻.在室內采用電纜橋架布線時，其電纜不應有黃麻或其他易延燃材料外護層。

The common problem of galvanized plastic spraying bridge in use is short circuit. The short circuit may be the internal short circuit of the cable, or the cable may be burnt out. The damage of the cable is light, but there are still obvious traces. The reason is that the current is too high or the quality of the cable is too poor. Generally speaking, the cable quality is too low, and the appearance will not show traces; This kind of fault may cause the current relay operation on the distribution cabinet, and the damage to the cable tray is very serious. When the cable tray is used indoors, the cable should not have jute or other flammable materials.
               

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 expansion and contraction of cable tray will occur in the process of use. Due to the change of ambient temperature, such as steel cable tray, the phenomenon of thermal expansion and cold contraction will appear. The effect of outdoor cable tray is greatly affected by temperature. Therefore, attention should be paid to the temperature change of high-temperature fan in use.

在有腐蝕或非常潮濕的場所采用電纜橋架布線時，應根據腐蝕介質的不同采取相應的防護措施，并宜選用塑料護套電纜。

When cable tray is used for wiring in places with corrosion or special humidity, corresponding protective measures should be taken according to different corrosive media, and plastic sheathed cables should be selected.

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, we need to find the correct model and use it according to the relevant regulations. Different types of cable tray have different application scope, so we need to find the appropriate bridge according to our own needs. Must not blindly choose to use, not only can not guarantee the effect of use, but also shorten the service life of the bridge.
