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.

導致電纜橋架老化的原因分析

Cause analysis of cable bridge aging

1、使用環境的溫度和濕度，如果是使用環境比較高，那么長時間使用更加容易產生老化現象，同時導致電纜橋架老化的另一個主要原因就是其環境濕度，如果濕度過大，其老化速度就會飛非?？?。

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、化學和電解腐蝕，如果是長期在酸性或者是堿性的環境中進行使用，那么電纜表皮經過長期的腐蝕就會降低絕緣，老化，甚損壞。

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、電纜線長時間的超負荷運作，在超負荷的狀態下運作，就會加速老化現象，同時高負荷運作產生過多的熱量，能夠擊穿電纜絕緣層，是非常危險的。

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、電纜橋架的機械損傷，機械損傷也是導致橋架產生老化的一個重要原因，同時機械損傷也會有可能導致內部電纜產生損壞，所以要對橋架采取必要的保護措施。

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、外力損傷，通常是由于外部的機械損傷所引起的，比如在進行施工過程中不注意對電纜線進行合理的保護，一些金屬材料碰到沒有保護的電纜線之后，就會容易引起損傷。

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、受潮等產生的腐蝕現象，電纜線的敷設通常都是在一些環境比較差的地方，比如將其安裝在潮濕陰暗的環境中，這時候其長時間受潮之后就會容易產生腐蝕現象，更終導致電纜線產生老化現象。

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、電纜線的超負荷運行，如果電纜線長時間在一個超負荷的環境中運行，那么就會產生過多的電流熱效應，使電纜線溫度升到，導致其老化。

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、環境和溫度。電纜所處的外界環境和熱源也會造成電纜溫度過高、絕緣擊穿，甚爆炸起火，產生非常嚴重的問題。

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.

如果山東電纜橋架的老化現象比較嚴重，那么要及時的進行維修，必要時進行一個徹底的更換，這樣才能夠起到一個更好的保護作用。

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.
