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(dǎo)致電纜橋架老化的原因分析

Cause analysis of cable bridge aging

1、使用環(huán)境的溫度和濕度，如果是使用環(huán)境比較高，那么長(zhǎng)時(shí)間使用更加容易產(chǎn)生老化現(xiàn)象，同時(shí)導(dǎo)致電纜橋架老化的另一個(gè)主要原因就是其環(huán)境濕度，如果濕度過大，其老化速度就會(huì)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(xué)和電解腐蝕，如果是長(zhǎng)期在酸性或者是堿性的環(huán)境中進(jìn)行使用，那么電纜表皮經(jīng)過長(zhǎng)期的腐蝕就會(huì)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(zhǎng)時(shí)間的超負(fù)荷運(yùn)作，在超負(fù)荷的狀態(tài)下運(yùn)作，就會(huì)加速老化現(xiàn)象，同時(shí)高負(fù)荷運(yùn)作產(chǎn)生過多的熱量，能夠擊穿電纜絕緣層，是非常危險(xiǎn)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(jī)械損傷，機(jī)械損傷也是導(dǎo)致橋架產(chǎn)生老化的一個(gè)重要原因，同時(shí)機(jī)械損傷也會(huì)有可能導(dǎo)致內(nèi)部電纜產(chǎn)生損壞，所以要對(duì)橋架采取必要的保護(hù)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(jī)械損傷所引起的，比如在進(jìn)行施工過程中不注意對(duì)電纜線進(jìn)行合理的保護(hù)，一些金屬材料碰到?jīng)]有保護(hù)的電纜線之后，就會(huì)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(chǎn)生的腐蝕現(xiàn)象，電纜線的敷設(shè)通常都是在一些環(huán)境比較差的地方，比如將其安裝在潮濕陰暗的環(huán)境中，這時(shí)候其長(zhǎng)時(shí)間受潮之后就會(huì)容易產(chǎn)生腐蝕現(xiàn)象，更終導(dǎo)致電纜線產(chǎn)生老化現(xiàn)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(fù)荷運(yùn)行，如果電纜線長(zhǎng)時(shí)間在一個(gè)超負(fù)荷的環(huán)境中運(yùn)行，那么就會(huì)產(chǎn)生過多的電流熱效應(yīng)，使電纜線溫度升到，導(dǎo)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(huán)境和溫度。電纜所處的外界環(huán)境和熱源也會(huì)造成電纜溫度過高、絕緣擊穿，甚爆炸起火，產(chǎn)生非常嚴(yán)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(xiàn)象比較嚴(yán)重，那么要及時(shí)的進(jìn)行維修，必要時(shí)進(jìn)行一個(gè)徹底的更換，這樣才能夠起到一個(gè)更好的保護(hù)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.
