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(jiàn)的問(wèn)題就是短路，短路可能是電纜內(nèi)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(huì)有很明顯的痕跡。會(huì)呈現(xiàn)的原因在于電流太大或許電纜質(zhì)量太差而形成的。總體來(lái)說(shuō)就是電纜質(zhì)量過(guò)低導(dǎo)致,外表上不會(huì)流露痕跡;這類(lèi)毛病可能會(huì)形成配電柜上的電流繼電器作業(yè)，對(duì)橋架形成的損壞十分嚴(yán)峻.在電纜橋架布線時(shí)，其電纜不應(yīng)有黃麻或其他易延燃材料外護(hù)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(guò)程中還會(huì)出現(xiàn)脹縮的問(wèn)題，由于環(huán)境溫度的變化，像是鋼制電纜橋架就會(huì)出現(xiàn)熱脹冷縮的現(xiàn)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(fēng)機(jī)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.

在有腐蝕或特別潮濕的場(chǎng)所采用電纜橋架布線時(shí)，應(yīng)根據(jù)腐蝕介質(zhì)的不同采取相應(yīng)的防護(hù)措施，并宜選用塑料護(hù)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(zhǔn)型號(hào)按照相關(guān)規(guī)定進(jìn)行使用，不同類(lèi)型的電纜橋架應(yīng)用范圍是不同的，要按照自己的需求來(lái)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(huì)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.
