Jinan cable bridge is widely used and flexible. It can not only be erected alone, but also be laid on the supports of various buildings. But there are often some aging and corrosion conditions, you must have encountered, today we will find out the relevant reasons, to help you understand.

1.绝缘的受潮情况：这种情况经常发生，经常发生在直埋或排气管内的电缆接头处;

1. Insulation dampness: this kind of situation often occurs at the cable joint directly buried or in the exhaust pipe;

2.化学原料腐蚀：如果电缆直接埋在酸碱区，往往会构成电缆腐蚀。铅皮或外保护层被腐蚀，维修层长期遭受化学腐蚀或电解腐蚀，导致维修层失效，绝缘下降，也会导致电缆问题;

2. Chemical raw material corrosion: if the cable is directly buried in the acid-base area, it will often constitute cable corrosion. The lead skin or outer protective layer is corroded, and the maintenance layer suffers from chemical corrosion or electrolytic corrosion for a long time, which leads to the failure of the maintenance layer and the degradation of insulation, which also leads to cable problems;

3.长期过载运行：进行过载运行和长期过载运行时，温度过高会加速绝缘老化，导致绝缘击穿。

3. Long term overload operation: during overload operation and long-term overload operation, too high temperature will accelerate insulation aging and cause insulation breakdown.

4.电缆接头故障：电缆接头是整个线路的脆弱部分，经常发生由人员直接故障(施工不良)引起的电缆接头故障。济南电缆桥框架表明，如果在电缆接头制造过程中接头没有紧密卷曲。原有网络加热不充分会造成电缆头绝缘下降，进而引发故障。

4. Cable joint failure: the cable joint is a vulnerable part of the whole line, which is often caused by the direct fault of personnel (poor construction). Jinan cable bridge frame shows that if the joint is not tightly crimped during the manufacturing process of cable joint. The insufficient heating of the original network will cause the cable head insulation to drop, and then cause the fault.

5.环境中的温度因素：电缆桥框架及其部件周围的外部环境和热源也会导致电缆温度过高，绝缘击穿，严重爆炸引起火灾。

5. Temperature factors in the environment: the external environment and heat source around the cable bridge frame and its components will also lead to high temperature of the cable, insulation breakdown, serious explosion and fire.

济南电缆桥架如果出现老化腐蚀现象时，比较简单的方法是镀锌处理一下，通过这种方法可以在表面生成一层铅材料膜，有利于减缓它的腐蚀和腐蚀速度。

If there is aging corrosion phenomenon in Jinan cable bridge, the simple method is galvanizing. Through this method, a layer of lead material film can be formed on the surface, which is conducive to slow down its corrosion and corrosion rate.
