style="text-indent:25px">電線電纜如果是在室外敷設(shè)的，容易受到環(huán)境的影響，對(duì)電線電纜造成損傷，所以電纜尤其需要注意的是防凍。在室外，經(jīng)常會(huì)被冰雪覆蓋，當(dāng)冰重量超過了電纜的規(guī)定承受重量，就容易導(dǎo)把傳輸鐵塔或者電線桿拉倒，電纜自身發(fā)生斷裂。給輸電造成比較大的麻煩。要想避免這種情況，有以下兩種方法：一、在選擇電纜的時(shí)候，需要選擇能夠抗寒的電纜，這就不會(huì)因?yàn)槭軆龆l(fā)生損害。再就是由于冰雪落在電線電纜上面，導(dǎo)致電纜受了外力發(fā)生旋轉(zhuǎn)，再加上重力的原因，電纜就比較容易斷裂。因此，線纜旋轉(zhuǎn)是導(dǎo)致覆冰的較主要的原因。而如果線纜是一根堅(jiān)硬的導(dǎo)體，當(dāng)雪堆積足夠多的時(shí)候，不容易產(chǎn)生扭轉(zhuǎn)，雪會(huì)自動(dòng)從導(dǎo)線上掉下。同時(shí)，由于電線電纜堅(jiān)硬密度不同，當(dāng)雪逐漸向冰塊凝固，達(dá)到一定程度會(huì)自動(dòng)碎裂。二、涂抹凍結(jié)涂料在電線電纜上充當(dāng)保護(hù)涂層。所謂凍結(jié)保護(hù)涂層，實(shí)際上是一種耐高溫隔熱涂料或反射隔熱涂料。實(shí)現(xiàn)保溫來達(dá)到防凍的目的。一般還具有防水、防腐、防潮、抗裂、防火、絕緣、和其他功能。凍結(jié)保護(hù)涂料在市場(chǎng)上有比較多不同的種類和性能。因此，在選購(gòu)時(shí)提醒您仍需要更多的對(duì)比度和檢查。陜西家裝常用電線電纜改造公司</p><p
