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.絕緣的受潮情況：這種情況經(jīng)常發(fā)生，經(jīng)常發(fā)生在直埋或排氣管內(nèi)的電纜接頭處;

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

2.化學(xué)原料腐蝕：如果電纜直接埋在酸堿區(qū)，往往會(huì)構(gòu)成電纜腐蝕。鉛皮或外保護(hù)層被腐蝕，維修層長(zhǎng)期遭受化學(xué)腐蝕或電解腐蝕，導(dǎo)致維修層失效，絕緣下降，也會(huì)導(dǎo)致電纜問(wèn)題;

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.長(zhǎng)期過(guò)載運(yùn)行：進(jìn)行過(guò)載運(yùn)行和長(zhǎng)期過(guò)載運(yùn)行時(shí)，溫度過(guò)高會(huì)加速絕緣老化，導(dǎo)致絕緣擊穿。

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.電纜接頭故障：電纜接頭是整個(gè)線路的脆弱部分，經(jīng)常發(fā)生由人員直接故障(施工不良)引起的電纜接頭故障。濟(jì)南電纜橋框架表明，如果在電纜接頭制造過(guò)程中接頭沒有緊密卷曲。原有網(wǎng)絡(luò)加熱不充分會(huì)造成電纜頭絕緣下降，進(jìn)而引發(fā)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.環(huán)境中的溫度因素：電纜橋框架及其部件周圍的外部環(huán)境和熱源也會(huì)導(dǎo)致電纜溫度過(guò)高，絕緣擊穿，嚴(yán)重爆炸引起火災(zāi)。

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.

濟(jì)南電纜橋架如果出現(xiàn)老化腐蝕現(xiàn)象時(shí)，比較簡(jiǎn)單的方法是鍍鋅處理一下，通過(guò)這種方法可以在表面生成一層鉛材料膜，有利于減緩它的腐蝕和腐蝕速度。

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.
