不合格電線(xian)電纜(lan)的危害

電(dian)(dian)線(xian)電(dian)(dian)纜是用于(yu)傳(chuan)輸電(dian)(dian)力、傳(chuan)輸信息和實現(xian)電(dian)(dian)磁能量(liang)轉換的一大類(lei)電(dian)(dian)工產品。在抽查過程(cheng)中，發現(xian)了大量(liang)的不合(he)格產品，這(zhe)些劣質產品給電(dian)(dian)力系統正常運行埋(mai)下(xia)諸多隱患。

1、標(biao)志(zhi)不合格(ge)(ge)的電(dian)(dian)(dian)線電(dian)(dian)(dian)纜。標(biao)志(zhi)是(shi)電(dian)(dian)(dian)線電(dian)(dian)(dian)纜使用(yong)識別產(chan)品(pin)基(ji)本(ben)信息的主要途徑，根據(ju)標(biao)準(zhun)規(gui)定標(biao)志(zhi)的主要內(nei)容是(shi)：產(chan)品(pin)型號、規(gui)格(ge)(ge)、標(biao)準(zhun)號、廠(chang)名、產(chan)地等(deng)在一定的標(biao)示間距(ju)內(nei)，當標(biao)志(zhi)不合格(ge)(ge)時，會(hui)造成施工人員(yuan)識別錯誤(wu)，嚴重時會(hui)引發電(dian)(dian)(dian)氣事故。

2、結(jie)構尺寸不(bu)合格的電(dian)(dian)(dian)線電(dian)(dian)(dian)纜(lan)。結(jie)構尺寸的主(zhu)要問題(ti)是護(hu)套(tao)厚度(du)(du)，絕(jue)緣(yuan)厚度(du)(du)，當電(dian)(dian)(dian)纜(lan)的護(hu)套(tao)和(he)絕(jue)緣(yuan)厚度(du)(du)不(bu)達(da)標時(shi)，致(zhi)使電(dian)(dian)(dian)線電(dian)(dian)(dian)纜(lan)耐電(dian)(dian)(dian)氣(qi)強度(du)(du)會嚴(yan)重降低，導(dao)致(zhi)電(dian)(dian)(dian)線電(dian)(dian)(dian)纜(lan)的使用(yong)壽命縮短，嚴(yan)重時(shi)可導(dao)致(zhi)電(dian)(dian)(dian)線電(dian)(dian)(dian)纜(lan)被擊穿，絕(jue)緣(yuan)（護(hu)套(tao)）層起不(bu)到正(zheng)常保護(hu)作用(yong)，從而發(fa)生電(dian)(dian)(dian)氣(qi)短路和(he)火災(zai)等(deng)現象。

3、護套(tao)式絕緣(yuan)(yuan)老化(hua)前(qian)的(de)抗張強度、伸長率合格的(de)電線電纜。絕緣(yuan)(yuan)護套(tao)老化(hua)前(qian)的(de)抗張強度、伸長率不合格直接大(da)大(da)縮短(duan)電線電纜的(de)工(gong)作用壽(shou)命，而且在施工(gong)或在長時間通電且溫度較高的(de)環(huan)境中，極易出(chu)現絕緣(yuan)(yuan)體斷裂，致使帶(dai)電導體裸露，發生(sheng)能觸電式短(duan)路(lu)危險。其(qi)不合格的(de)主要原(yuan)因是使用了(le)再生(sheng)料生(sheng)產(chan)，以(yi)降低產(chan)品成本，二是不具備生(sheng)產(chan)資格小型企(qi)業。

4、導體(ti)(ti)電(dian)阻(zu)不合格的(de)電(dian)線。導體(ti)(ti)電(dian)阻(zu)主要(yao)(yao)是(shi)考核電(dian)線電(dian)纜的(de)導體(ti)(ti)材料以及截(jie)(jie)面是(shi)否符合的(de)重(zhong)要(yao)(yao)指標。當導體(ti)(ti)電(dian)阻(zu)超標時(shi)，就增大了電(dian)流在(zai)線路上通過(guo)時(shi)的(de)損耗(hao)，加劇了電(dian)線電(dian)纜的(de)發(fa)熱。導體(ti)(ti)電(dian)阻(zu)不合格的(de)原(yuan)因(yin)，主要(yao)(yao)進(jin)企業(ye)為了降(jiang)低成本(ben)，將占(zhan)原(yuan)材料成本(ben)80%的(de)銅材縮水，要(yao)(yao)么(me)降(jiang)低導體(ti)(ti)的(de)截(jie)(jie)面積，要(yao)(yao)么(me)使用含雜質(zhi)過(guo)高的(de)再生銅，這樣(yang)致使電(dian)線電(dian)纜的(de)導體(ti)(ti)電(dian)阻(zu)嚴重(zhong)超標，在(zai)使用過(guo)程中(zhong)除易(yi)引發(fa)火災(zai)，還(huan)會加速包覆在(zai)電(dian)線外的(de)絕緣(yuan)層的(de)老化。

在購買電線電纜的過程中，消(xiao)費者應注(zhu)意以下(xia)幾個(ge)事

第一、要觀(guan)察電線的(de)外觀(guan)。合格產(chan)品(pin)的(de)絕緣（護套）層柔軟、有韌性和伸縮性、表面層緊密(mi)、光滑、無粗糙(cao)感(gan)。如果包裹電線的(de)塑(su)料很容易被剝去，則存在塑(su)料強(qiang)度不夠的(de)問題。

第二、要看電(dian)線的(de)截(jie)面。合格產品的(de)銅芯或鋁芯表面應該(gai)具有(you)金(jin)屬光澤，表面發黑(hei)的(de)銅或表面發白的(de)鋁說明已被氧化。

第三、在購買(mai)電線時(shi)應(ying)注(zhu)意(yi)查看質量(liang)合格(ge)證書。如果電線的(de)(de)質量(liang)合格(ge)，那么其電線質量(liang)應(ying)該也受過檢驗，不會有(you)太大的(de)(de)問(wen)題。
