The structure of cable tray includes trough type, tray type, ladder type and net type, which is composed of bracket, bracket and installation accessories. The bridge in the building can be erected separately or laid on the supports of various buildings (structures). It has the characteristics of simple structure, beautiful appearance, flexible configuration and convenient maintenance. All parts shall be galvanized and installed on the bridge outside the building. However, the bridge will appear aging phenomenon in use, so what are the reasons for aging? What process can we take to prevent the aging of cable tray? The following is the introduction of Shandong cable tray manufacturer:

1.絕緣受潮狀況：一般經常出現這種情況，經常出現在直埋或排管里的電纜接頭處;

1. Insulation damp condition: generally, it often occurs at the cable joint directly buried or arranged in the pipe;

2.化工原料的腐蝕：假如電纜直接埋在酸堿區域內，往往會構成電纜的腐蝕。鉛皮或外護層被腐蝕，維護層因長時間遭受化學腐蝕或電解腐蝕，致使維護層失效，絕緣下降，也會導致電纜毛病;

2. Corrosion of chemical raw materials: if the cable is directly buried in the acid-base area, it will often form the corrosion of the cable. The lead skin or outer protective layer is corroded, and the maintenance layer is subject to chemical corrosion or electrolytic corrosion for a long time, resulting in the failure of the maintenance layer, the decline of insulation, and the cable fault;

3.長時間過負荷運轉：當經過超負荷運轉，長時間超負荷運轉時，過高的溫度會加快絕緣的老化，以至絕緣被擊穿。

3. Long time overload operation: after overload operation and long time overload operation, too high temperature will accelerate the aging of insulation, and even the insulation will be broken down.

4.電纜接頭毛病：電纜接頭是整個線路中比較脆弱的部分，由人員直接過錯(施工不良)引發的電纜接頭毛病時常發作。山東電纜橋架表示施工人員在制造電纜接頭過程中，假如有接頭壓接不緊。加熱不充分等原網，都會導致電纜頭絕緣下降，然后引發事端。

4. Cable joint fault: the cable joint is a vulnerable part of the whole line, and the cable joint fault caused by personnel's direct fault (poor construction) often occurs. Shandong cable bridge said that the construction personnel in the process of manufacturing cable joints, if there is a joint crimping is not tight. If the original network is not heated sufficiently, the insulation of the cable head will drop, and then cause trouble.
           

5.環境中的溫度因素：電纜橋架及其部件周邊的外界環境和熱源也會構成電纜溫度過高.絕緣擊穿，嚴峻的構成爆破起火。

5. Environmental temperature factors: the external environment and heat source around the cable bridge and its components will also cause the cable temperature to be too high, insulation breakdown, and severe explosion and fire.

那么山東電纜橋架出現這種老化現象時，我們應該怎樣進行處理呢?答案是進行鍍鋅處理，也就是在表面鍍上一層鉛材料，浸鋅作為一種犧牲陽電位來維護陰電位金屬的辦法，壽命取決于它的腐蝕鋅鍍層的阻力和腐蝕速度。

So how should we deal with this aging phenomenon of cable bridge in Shandong? The answer is galvanizing, that is, coating a layer of lead on the surface. As a way of sacrificing the positive potential to maintain the negative potential metal, the life of galvanizing depends on its corrosion resistance and corrosion rate.
