如果电缆机架内部的电缆短路，配电板内的电流继电器会动作，可能会对电缆造成较大的损伤。通常是因为电缆质量不好。电缆也有可能烧毁，一方也有可能烧毁。这个问题特别严重。如果电缆或电缆桥架损坏，通常是因为过电流、过载或电缆质量差。因此，需要定期检查和维护。

If the cable inside the cable rack is short circuited, the current relay in the distribution board will act, which may cause great damage to the cable. Usually because the cable is of poor quality. The cable may also be burned, and one party may also be burned. This problem is particularly serious. If the cable or cable tray is damaged, it is usually due to overcurrent, overload or poor cable quality. Therefore, regular inspection and maintenance are required.

电缆的各相短路。同样，该故障会使配电盘的电流继电器和电压继电器工作，电缆在故障点会严重损坏。只有一相电缆桥架破损，电流继电器工作。故障点的损坏很轻微，但很明显。相电流过大，可能是电缆的质量造成的。

Each phase of the cable is short circuited. Similarly, this fault will make the current relay and voltage relay of the distribution board work, and the cable will be seriously damaged at the fault point. Only one phase cable tray is damaged, and the current relay works. The damage at the fault point is slight, but obvious. The large phase current flow may be caused by the quality of the cable.

在工程设计中，电缆桥架的布置必须根据经济公正性、技术可行性、运行性等因素进行综合比较，确定好的方案，充分满足施工安装、维修检查和电缆敷设的要求。

In the engineering design, the layout of cable tray must be comprehensively compared according to economic fairness, technical feasibility, operation safety and other factors, and a good scheme must be determined to fully meet the requirements of construction and installation, maintenance and inspection, and cable laying.

桥架、线槽及其吊架用于有侵蚀性的环境时，必须用抗侵蚀的刚性材料制造，或者采用防腐处理，防腐处理方法必须满足工程环境和耐久性的要求。在要求耐侵蚀功能的地方，或者要求清洁的地方，使用铝合金制的电缆桥架。

When bridges, trunking and hangers are used in corrosive environment, they must be made of corrosion-resistant rigid materials or treated with anti-corrosion treatment. The anti-corrosion treatment method must meet the requirements of engineering environment and durability. Where corrosion resistance is required, or where cleaning is required, aluminum alloy cable trays shall be used.

增加电缆的总平均布负荷值，管理机架的强度。根据初步确定的桥架形式、规格及支点间距离，查阅样品资料，反复检查间隔和电缆桥架形式，直满足负荷要求。确定电缆桥架的宽度、层数、支撑点的样式和间距，以及电缆各层在机架上的分布。

Increase the total average distribution load of the cable and manage the strength of the rack. According to the preliminarily determined bridge form, specification and distance between fulcrums, consult the sample data, and repeatedly check the spacing and cable bridge form until the load requirements are met. Determine the width of cable tray, the number of layers, the style and spacing of support points, and the distribution of each layer of cable on the rack.

济南电缆桥架厂家提醒您，工作环境受到日照、油、侵蚀性液体、可燃性粉尘等的影响，或者受到屏蔽电磁干扰的电缆布线等环境要求。请选择没有孔的托盘式电缆桥架进行使用。

Jinan cable tray manufacturer reminds you that the working environment is affected by sunshine, oil, corrosive liquid, combustible dust, or environmental requirements such as cable wiring shielded from electromagnetic interference. Please select a tray type cable tray without holes for use.
