The application of cable tray is very extensive, but after a long time of use, it is easy to produce aging phenomenon. After aging, the safety of cable tray will be greatly reduced, so it is necessary to replace it in time. Let's take a look at the causes of cable tray aging.

导致电缆桥架老化的原因分析

Cause analysis of cable bridge aging

1、使用环境的温度和湿度，如果是使用环境比较高，那么长时间使用更加容易产生老化现象，同时导致电缆桥架老化的另一个主要原因就是其环境湿度，如果湿度过大，其老化速度就会飞非常看。

1. The temperature and humidity of the use environment, if the use environment is relatively high, then the aging phenomenon is more likely to occur after a long time of use. At the same time, another main reason for the aging of cable tray is its environmental humidity. If the humidity is too high, its aging speed will be very impressive.

2、化学和电解腐蚀，如果是长期在酸性或者是碱性的环境中进行使用，那么电缆表皮经过长期的腐蚀就会降低绝缘，老化，甚损坏。

2. Chemical and electrolytic corrosion, if it is used in acidic or alkaline environment for a long time, the insulation, aging and even damage of cable skin will be reduced after long-term corrosion.

3、电缆线长时间的超负荷运作，在超负荷的状态下运作，就会加速老化现象，同时高负荷运作产生过多的热量，能够击穿电缆绝缘层，是非常危险的。

3. If the cable is operated under overload condition for a long time, the aging phenomenon will be accelerated. At the same time, excessive heat generated by high load operation can break through the cable insulation, which is very dangerous.

4、电缆桥架的机械损伤，机械损伤也是导致桥架产生老化的一个重要原因，同时机械损伤也会有可能导致内部电缆产生损坏，所以要对桥架采取必要的保护措施。

4. Mechanical damage of cable tray, mechanical damage is also an important reason for the aging of cable tray. At the same time, mechanical damage may lead to internal cable damage, so it is necessary to take necessary protection measures for the bridge.

 

5、外力损伤，通常是由于外部的机械损伤所引起的，比如在进行施工过程中不注意对电缆线进行合理的保护，一些金属材料碰到没有保护的电缆线之后，就会容易引起损伤。

5. External force damage is usually caused by external mechanical damage. For example, in the process of construction, if the cable is not properly protected, some metal materials will easily cause damage after encountering unprotected cable.

6、受潮等产生的腐蚀现象，电缆线的敷设通常都是在一些环境比较差的地方，比如将其安装在潮湿阴暗的环境中，这时候其长时间受潮之后就会容易产生腐蚀现象，更终导致电缆线产生老化现象。

6. For the corrosion phenomenon caused by damp, the cable is usually laid in some places with poor environment, for example, it is installed in a humid and dark environment. At this time, it is easy to produce corrosion after a long time of damp, and eventually lead to the aging phenomenon of cable.

7、电缆线的超负荷运行，如果电缆线长时间在一个超负荷的环境中运行，那么就会产生过多的电流热效应，使电缆线温度升到，导致其老化。

7. If the cable runs in an overload environment for a long time, it will produce excessive current thermal effect, which will make the cable temperature rise to and lead to its aging.

8、环境和温度。电缆所处的外界环境和热源也会造成电缆温度过高、绝缘击穿，甚爆炸起火，产生非常严重的问题。

8. Environment and temperature. The external environment and heat source in which the cable is located can also cause high temperature, insulation breakdown, and even explosion and fire, resulting in very serious problems.

如果山东电缆桥架的老化现象比较严重，那么要及时的进行维修，必要时进行一个彻底的更换，这样才能够起到一个更好的保护作用。

If the aging phenomenon of cable tray in Shandong Province is serious, it is necessary to repair it in time and replace it completely if necessary, so as to play a better protection role.
