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?

镀锌喷塑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，毛病处电缆损坏较轻，但还是会有很明显的痕迹。会呈现的原因在于电流太大或许电缆质量太差而形成的。总体来说就是电缆质量过低导致,外表上不会流露痕迹;这类毛病可能会形成配电柜上的电流继电器作业，对桥架形成的损坏十分严峻.在室内采用电缆桥架布线时，其电缆不应有黄麻或其他易延燃材料外护层。

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.

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 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.

在有腐蚀或特别潮湿的场所采用电缆桥架布线时，应根据腐蚀介质的不同采取相应的防护措施，并宜选用塑料护套电缆。

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.

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, 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.
