因为热浸锌电缆桥架属于金属材质，金属材质都带有一定的导电性，电缆桥架跨接线用于两节桥架连接处,它起到漏电保护的作用。

Because hot-dip galvanized cable trays are made of metal materials, which have a certain degree of conductivity, cable tray jumper wires are used at the connection between two cable trays to provide leakage protection.

锌桥架之间可利用镀锌连接板作为跨接线,把桥架连成一体在连接板两端的两只连接螺栓上加镀锌分层桥架安装,先安装上层,后安装下层,上、下层之间距离要留有余量,有利于后期电缆敷设和检修。即将各个桥架连接起来，防止漏电时有桥架不与其他桥架相连而导致漏电造成人身危害，会有接地线将各段桥架连接大地。

Galvanized connecting plates can be used as jumper wires between zinc cable trays to connect the trays together. Galvanized layered cable trays can be installed on the two connecting bolts at both ends of the connecting plates. The upper layer should be installed first, and then the lower layer should be installed. There should be a margin between the upper and lower layers to facilitate cable laying and maintenance in the later stage. Connect each bridge frame together to prevent leakage and personal harm caused by the bridge frame not being connected to other bridges. A grounding wire will connect each section of the bridge frame to the ground.

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。

A common problem with cable trays in use is short circuits, which can be caused by internal short circuits or cable burnout. Overall, it is due to low cable quality.

热浸锌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。

Hot dip galvanized cable trays may also experience expansion and contraction during use. Due to changes in ambient temperature, steel cable trays may experience thermal expansion and contraction. The function of outdoor cable trays is greatly affected by temperature, so attention should be paid to changes in the temperature of high-temperature fans during use.

一般的住宅或者 是等，也都会使用到这样的热浸锌电缆桥架，安装比较方便，而且使用年寿命长，也可以有效避免危险的发生。但是建筑物内使用 的桥架一定要注意美观性，并重才能够确保实用性。

Generally, residential buildings or shopping malls also use hot-dip galvanized cable trays, which are easy to install and have a long service life, effectively avoiding the occurrence of danger. However, the bridge used in the building must pay attention to aesthetics, and pay equal attention to ensure practicality.
