電氣設備造成的火災事故逐漸提升，在其中因為電線電纜緣故引起的火災事故占非常大的占比。電線電纜著火的緣故有什么呢？湖北電纜價格小編為大家詳細介紹：

(1)電纜載(zai)流設計方案不善(shan) 。

電(dian)纜(lan)(lan)電(dian)纜(lan)(lan)載流量挑選不善，一部(bu)分電(dian)纜(lan)(lan)長(chang)期性超(chao)負(fu)荷或常常超(chao) 負(fu)載運作，升溫(wen)過(guo)高及電(dian)纜(lan)(lan)斷面 、隧(sui)道(dao)施工存水(shui)所致(zhi)使電(dian)纜(lan)(lan)絕(jue)緣層脆化 、受(shou) 潮(chao) 、過(guo) 熱造成短路(lu)故障自燃 。

(2)電纜(lan)安(an)裝工(gong)程施工(gong)不善 。企(qi)業以便控制成本(ben) ，未(wei)采用(yong)防火安(an)全對策 ，電纜(lan)鋪設摻雜 、過(guo)度集中化 、堆壓(ya)比較嚴重 、排熱欠佳 ，經常把起(qi)燃后會造成有毒濃煙的中底(di)壓(ya)電纜(lan)與髙(gao)壓(ya)電纜(lan)一起(qi)鋪設。

(3)電(dian)線電(dian)纜故(gu)障。

① 加工(gong)(gong)工(gong)(gong)藝不光(guang)滑 、絕緣層(ceng)返潮(chao) ， 致使電(dian)(dian)(dian)(dian)(dian)纜頭及終(zhong)端盒在(zai)運作中(zhong)造(zao)成故障(zhang)(zhang)而自燃發(fa)生(sheng)爆炸 ； ②一(yi)部分電(dian)(dian)(dian)(dian)(dian)纜技術工(gong)(gong)工(gong)(gong) 藝實際(ji)操作關不緊 ，不注意衛(wei)生(sheng) ，殘渣(zha)、廢棄物等清理不足均易導致頁面(mian)接(jie)(jie)觸(chu)不良現(xian)象(xiang)(xiang) ；③連接(jie)(jie)頭加工(gong)(gong)工(gong)(gong)藝不精(jing) 、制(zhi)做品質不高 、防(fang)火(huo)安(an)全對(dui)策較少 ，在(zai)故障(zhang)(zhang)狀況下受(shou)高電(dian)(dian)(dian)(dian)(dian)壓(ya) 、大(da)電(dian)(dian)(dian)(dian)(dian)流(liu)的沖(chong)擊性造(zao)成連接(jie)(jie)頭發(fa)生(sheng)爆炸著火(huo) ；④ 電(dian)(dian)(dian)(dian)(dian)纜接(jie)(jie)地裝(zhuang)置欠佳(jia)。電(dian)(dian)(dian)(dian)(dian)線接(jie)(jie)頭電(dian)(dian)(dian)(dian)(dian)焊焊接(jie)(jie)不穩固 、接(jie)(jie)觸(chu)不良現(xian)象(xiang)(xiang) 、電(dian)(dian)(dian)(dian)(dian)阻值偏大(da) ，導致電(dian)(dian)(dian)(dian)(dian)纜接(jie)(jie)地裝(zhuang)置故障(zhang)(zhang)電(dian)(dian)(dian)(dian)(dian)流(liu)比(bi)一(yi)切正常短路故障(zhang)(zhang)電(dian)(dian)(dian)(dian)(dian)流(liu)小(xiao)，使電(dian)(dian)(dian)(dian)(dian)流(liu)保護(hu)裝(zhuang)置不可(ke)以立即斷(duan)開故障(zhang)(zhang) ，而出現(xian)電(dian)(dian)(dian)(dian)(dian)孤、火(huo)花放電(dian)(dian)(dian)(dian)(dian) 。

(4)電纜產(chan)品質量問(wen)題。

電纜線品質良莠不齊，一部分店家(jia)以(yi)便節約成本，購置(zhi)不符國家(jia)行業(ye)標準(zhun)的線纜，引起了安全生產事故(gu)。
