The cable tray insulation is covered by a separate shell. Once the protective effect is not good and exposed to the air for a long time, the insulating layer will be greatly reduced, and with the growth of age, the insulating layer will gradually harden until autumn. At this time, the insulation effect is poor. Usually, cable insulation is made of rubber and plastic, so what is the reason for its aging?

接頭通常出現(xiàn)在埋入電纜中，或者在這種情況下出現(xiàn)在排氣管中。我們可以舉個(gè)例子。當(dāng)電纜接頭的不合格產(chǎn)品處于潮濕環(huán)境時(shí)，接頭會(huì)發(fā)展成土壤或水蒸氣。此時(shí)，如果有電場(chǎng)，防火電纜橋架學(xué)生將逐漸形成直接影響電纜絕緣的水樹(shù)。從而引起了引起失敗的公司的問(wèn)題。

Connectors usually appear in buried cables or, in this case, in exhaust pipes. We can give an example. When the unqualified products of cable joints are in a humid environment, the joints will develop into soil or water vapor. At this time, if there is an electric field, the fireproof cable bridge will gradually form a water tree that directly affects the cable insulation. This has led to the problems of failed companies.

化學(xué)原料的腐蝕。對(duì)于埋入式電纜，這將直接導(dǎo)致電纜載體鎧裝電纜N，引線板或外部護(hù)套區(qū)域發(fā)生酸-堿相互作用，然后通過(guò)化學(xué)和電解蝕刻保護(hù)層，隨后破壞腐蝕性物質(zhì)保護(hù)層，減少絕緣，還會(huì)導(dǎo)致電纜故障。

Corrosion of chemical raw materials. For buried cables, this will directly lead to acid alkali interaction in the armored cable n of the cable carrier, the lead plate or the area of the outer sheath, and then etch the protective layer through chemical and electrolytic etching, and then destroy the protective layer of corrosive substances, reduce the insulation, and also lead to cable failure.

3.長(zhǎng)期過(guò)載已在運(yùn)行。

3. Long term overload has been in operation.

就電纜而言，導(dǎo)體會(huì)發(fā)熱。當(dāng)電纜溫度升高時(shí)，負(fù)載電流將加速絕緣層的老化，直到發(fā)生擊穿時(shí)間。特別是在夏天，電纜橋架的故障將變得更加嚴(yán)重。

In the case of cables, the conductor will heat up. When the cable temperature rises, the load current will accelerate the aging of the insulation layer until the breakdown time occurs. Especially in summer, the failure of cable tray will become more serious.

4.電纜連接器故障。

4. Cable connector failure.

實(shí)際上，我們系統(tǒng)的故障應(yīng)歸因于管理人員的不當(dāng)操作。例如，當(dāng)施工技術(shù)人員使電纜接頭開(kāi)始?jí)航硬⑶壹訜岵怀浞謺r(shí)，這將導(dǎo)致電纜頭的絕緣性能下降。

In fact, the failure of our system should be attributed to the improper operation of managers. For example, when the construction technician starts crimping the cable joint and the heating is insufficient, this will lead to the decline of the insulation performance of the cable head.

5.環(huán)境溫度系數(shù)：

5. Ambient temperature coefficient:

外部環(huán)境以及電纜橋架和電纜，高溫，絕緣擊穿，起火甚爆炸的溫度影響。

External environment, cable tray and cable, high temperature, insulation breakdown, fire and even explosion.

6.外部損壞。

6. External damage.

許多電纜故障中的大多數(shù)電流是由機(jī)械損壞引起的。例如：防火電纜橋架當(dāng)我們安裝的布線施工技術(shù)不規(guī)范時(shí)，很容易在我國(guó)造成機(jī)械損壞，因?yàn)槟菚r(shí)有時(shí)損壞并不嚴(yán)重，但是經(jīng)過(guò)一段時(shí)間的運(yùn)營(yíng)成本，它就會(huì)開(kāi)始出現(xiàn)直到形式故障，嚴(yán)重的故障可能導(dǎo)致短路，直接影響到公司生產(chǎn)教育的橋梁和動(dòng)力單元

Most of the current in many cable faults is caused by mechanical damage. For example, when the wiring construction technology we installed is not standardized, it is easy to cause mechanical damage in China, because sometimes the damage is not serious, but after a period of operation cost, it will begin to appear until formal failure. Serious failure may lead to short circuit and directly affect the bridges and power units of the company's production and education
