因(yin)電(dian)(dian)(dian)(dian)(dian)阻(zu)的(de)存在(zai)，電(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)(lan)在(zai)運用時發(fa)熱是不可防止(zhi)的(de)，當(dang)熱量在(zai)必(bi)定(ding)規模內能正常流(liu)失(shi)時，則(ze)電(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)(lan)能夠正常運作，但(dan)假如(ru)因(yin)為負載(zai)電(dian)(dian)(dian)(dian)(dian)流(liu)的(de)增(zeng)(zeng)大或其他(ta)問題造(zao)成(cheng)電(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)(lan)表面溫度上升，熱量無(wu)法及時流(liu)失(shi)，那么電(dian)(dian)(dian)(dian)(dian)阻(zu)會跟著溫度的(de)升高而增(zeng)(zeng)大，那么電(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)(lan)發(fa)熱則(ze)會更嚴峻，形成(cheng)一種惡性循環，假如(ru)不立即(ji)處理，輕則(ze)加速絕緣老化直至(zhi)電(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)(lan)擊(ji)穿，重則(ze)形成(cheng)絕緣熔化、短路乃至(zhi)起火，結果將(jiang)無(wu)法想象。

引起電(dian)纜(lan)反常(chang)發熱(re)的原(yuan)因(yin)有許多，下(xia)面勝宇電(dian)纜(lan)就共享(xiang)一些(xie)電(dian)纜(lan)常(chang)見的發熱(re)原(yuan)因(yin)，希(xi)望能幫到我們。　

電(dian)力電(dian)纜在運轉(zhuan)中(zhong)發熱原因：

1、電(dian)(dian)纜(lan)導體電(dian)(dian)阻不符合標準要求，形成電(dian)(dian)纜(lan)在運(yun)轉中產生發熱(re)現象。這是(shi)產品質量上的(de)問題，因而選(xuan)(xuan)購時必定要選(xuan)(xuan)用有質量保證(zheng)的(de)電(dian)(dian)纜(lan)。　

2、電(dian)纜挑選型不妥，形成運(yun)用(yong)的(de)(de)電(dian)纜的(de)(de)導體截面過小，運(yun)轉中產(chan)(chan)生過載(zai)現(xian)象(xiang)，長時(shi)間運(yun)用(yong)后，電(dian)纜的(de)(de)發熱和(he)散熱不平衡致使產(chan)(chan)生發熱現(xian)象(xiang)。應根(gen)據(ju)實(shi)踐運(yun)用(yong)情況挑選相(xiang)應載(zai)流量(liang)的(de)(de)電(dian)纜，一起防止電(dian)纜超負荷運(yun)用(yong)。

3、電纜(lan)裝置時(shi)擺放過于密布(bu)，通(tong)風散熱作用欠好(hao)，或(huo)電纜(lan)接近別(bie)的熱源(yuan)太近，影響了電纜(lan)的正常散熱，也有或(huo)許形成電纜(lan)在運(yun)轉中產生(sheng)發(fa)熱現象。

4、接頭制作技能欠(qian)好，壓接不(bu)嚴密，形(xing)成接頭處觸(chu)摸(mo)電(dian)阻過大，也會使電(dian)纜產生發熱現象。

5、電纜相間絕(jue)緣功能欠好，形成絕(jue)緣電阻較(jiao)小(xiao)，運轉中也會產生發(fa)熱現象。

6、鎧裝電纜(lan)部分護套(tao)破(po)損，進水后(hou)絕(jue)緣功能呈現緩慢損壞(huai)現象(xiang)，形(xing)成絕(jue)緣電阻(zu)逐漸下降，也(ye)會形(xing)成電纜(lan)運(yun)轉(zhuan)中產生發熱現象(xiang)。

電(dian)(dian)(dian)力(li)電(dian)(dian)(dian)纜(lan)(lan)(lan)產(chan)生發熱(re)現(xian)象后，如不找到原(yuan)因及時排除(chu)(chu)一些(xie)故障，電(dian)(dian)(dian)纜(lan)(lan)(lan)持續接連通電(dian)(dian)(dian)運(yun)轉后將(jiang)產(chan)生絕緣熱(re)擊穿現(xian)象。形成電(dian)(dian)(dian)纜(lan)(lan)(lan)產(chan)生相間短路跳閘現(xian)象，嚴峻的(de)或(huo)許引(yin)起火災。想處理(li)電(dian)(dian)(dian)纜(lan)(lan)(lan)發熱(re)的(de)問(wen)題(ti)，電(dian)(dian)(dian)纜(lan)(lan)(lan)的(de)運(yun)用情(qing)況(kuang)很要害，除(chu)(chu)了(le)合理(li)地(di)運(yun)用電(dian)(dian)(dian)纜(lan)(lan)(lan)，還可以通過(guo)替換(huan)更優質的(de)電(dian)(dian)(dian)纜(lan)(lan)(lan)，從根本上改(gai)進電(dian)(dian)(dian)纜(lan)(lan)(lan)發熱(re)的(de)問(wen)題(ti)，為(wei)了(le)進步電(dian)(dian)(dian)纜(lan)(lan)(lan)個方(fang)面的(de)功能，勝(sheng)宇(yu)電(dian)(dian)(dian)纜(lan)(lan)(lan)生產(chan)出YJV交聯聚(ju)乙烯絕緣電(dian)(dian)(dian)力(li)電(dian)(dian)(dian)纜(lan)(lan)(lan)，這種電(dian)(dian)(dian)纜(lan)(lan)(lan)的(de)一大特點是長(chang)時間最(zui)高(gao)(gao)工(gong)作(zuo)時候的(de)溫度提升到90℃，一起勝(sheng)宇(yu)電(dian)(dian)(dian)纜(lan)(lan)(lan)選用了(le)高(gao)(gao)純度無氧(yang)銅作(zuo)為(wei)導體，電(dian)(dian)(dian)阻更小發熱(re)量也少(shao)，保(bao)證(zheng)線路更安全地(di)運(yun)轉，進一步減(jian)少(shao)了(le)電(dian)(dian)(dian)纜(lan)(lan)(lan)擊穿、短路、起火的(de)危險(xian)。
