不合格電線電纜的危害

電(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)纜是用(yong)于傳輸電(dian)(dian)(dian)力、傳輸信(xin)息和實現(xian)電(dian)(dian)(dian)磁能量(liang)轉換的(de)一大(da)類電(dian)(dian)(dian)工產(chan)品(pin)。在抽查過(guo)程中，發(fa)現(xian)了大(da)量(liang)的(de)不合格產(chan)品(pin)，這些劣(lie)質產(chan)品(pin)給電(dian)(dian)(dian)力系統(tong)正常運行埋(mai)下諸多隱患。

1、標(biao)志不合格(ge)的(de)(de)電線(xian)電纜。標(biao)志是電線(xian)電纜使用識別(bie)產(chan)品(pin)(pin)基本信息的(de)(de)主要途徑，根(gen)據標(biao)準規定(ding)標(biao)志的(de)(de)主要內容是：產(chan)品(pin)(pin)型號(hao)、規格(ge)、標(biao)準號(hao)、廠名、產(chan)地等在一(yi)定(ding)的(de)(de)標(biao)示間距內，當標(biao)志不合格(ge)時，會造(zao)成施(shi)工(gong)人員識別(bie)錯誤，嚴重時會引發電氣(qi)事故。

2、結(jie)構尺(chi)(chi)寸(cun)不(bu)(bu)合格(ge)的(de)電(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)纜(lan)(lan)(lan)。結(jie)構尺(chi)(chi)寸(cun)的(de)主(zhu)要問題是護套(tao)(tao)厚(hou)度(du)，絕(jue)緣厚(hou)度(du)，當(dang)電(dian)(dian)(dian)纜(lan)(lan)(lan)的(de)護套(tao)(tao)和絕(jue)緣厚(hou)度(du)不(bu)(bu)達標時(shi)，致(zhi)使電(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)纜(lan)(lan)(lan)耐(nai)電(dian)(dian)(dian)氣強度(du)會嚴重降低，導致(zhi)電(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)纜(lan)(lan)(lan)的(de)使用(yong)壽命縮短，嚴重時(shi)可導致(zhi)電(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)纜(lan)(lan)(lan)被擊穿，絕(jue)緣（護套(tao)(tao)）層起不(bu)(bu)到正(zheng)常保(bao)護作用(yong)，從而發生電(dian)(dian)(dian)氣短路和火災等現象(xiang)。

3、護套(tao)式絕(jue)緣老(lao)化前(qian)的(de)(de)抗張強度、伸(shen)長率合(he)格的(de)(de)電(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)纜(lan)。絕(jue)緣護套(tao)老(lao)化前(qian)的(de)(de)抗張強度、伸(shen)長率不合(he)格直接(jie)大大縮短電(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)纜(lan)的(de)(de)工作用(yong)(yong)壽命，而且(qie)在施工或在長時間通電(dian)(dian)(dian)且(qie)溫(wen)度較高的(de)(de)環境中，極(ji)易出現絕(jue)緣體(ti)斷(duan)裂，致使帶電(dian)(dian)(dian)導體(ti)裸露，發生(sheng)能觸電(dian)(dian)(dian)式短路危險(xian)。其不合(he)格的(de)(de)主要(yao)原因是使用(yong)(yong)了再生(sheng)料生(sheng)產(chan)，以降低產(chan)品成(cheng)本，二是不具備生(sheng)產(chan)資格小型企業。

4、導(dao)(dao)體(ti)(ti)電(dian)(dian)(dian)(dian)(dian)阻不(bu)合(he)格的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)線。導(dao)(dao)體(ti)(ti)電(dian)(dian)(dian)(dian)(dian)阻主(zhu)要(yao)(yao)是考核電(dian)(dian)(dian)(dian)(dian)線電(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)的(de)(de)(de)導(dao)(dao)體(ti)(ti)材料以及截面(mian)是否符合(he)的(de)(de)(de)重要(yao)(yao)指標。當導(dao)(dao)體(ti)(ti)電(dian)(dian)(dian)(dian)(dian)阻超標時，就增大了(le)電(dian)(dian)(dian)(dian)(dian)流在(zai)線路(lu)上通(tong)過(guo)時的(de)(de)(de)損耗，加(jia)劇了(le)電(dian)(dian)(dian)(dian)(dian)線電(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)的(de)(de)(de)發熱。導(dao)(dao)體(ti)(ti)電(dian)(dian)(dian)(dian)(dian)阻不(bu)合(he)格的(de)(de)(de)原因，主(zhu)要(yao)(yao)進企業(ye)為了(le)降低(di)成本(ben)，將占(zhan)原材料成本(ben)80%的(de)(de)(de)銅材縮水，要(yao)(yao)么降低(di)導(dao)(dao)體(ti)(ti)的(de)(de)(de)截面(mian)積(ji)，要(yao)(yao)么使(shi)用含(han)雜質過(guo)高的(de)(de)(de)再生銅，這樣致使(shi)電(dian)(dian)(dian)(dian)(dian)線電(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)的(de)(de)(de)導(dao)(dao)體(ti)(ti)電(dian)(dian)(dian)(dian)(dian)阻嚴重超標，在(zai)使(shi)用過(guo)程中除易引發火災，還會加(jia)速包覆在(zai)電(dian)(dian)(dian)(dian)(dian)線外的(de)(de)(de)絕緣層的(de)(de)(de)老化。

在購買電線電纜的過程(cheng)中(zhong)，消費者(zhe)應注意以下幾個事

第一、要(yao)觀察(cha)電(dian)線(xian)的外觀。合格產品(pin)的絕緣（護套）層柔(rou)軟(ruan)、有韌性(xing)和伸縮(suo)性(xing)、表面層緊密(mi)、光滑、無(wu)粗糙感。如果包(bao)裹電(dian)線(xian)的塑(su)(su)料(liao)很容易被剝去，則存在(zai)塑(su)(su)料(liao)強(qiang)度(du)不夠的問題。

第二、要看電線的(de)截面(mian)(mian)。合(he)格產品(pin)的(de)銅芯或鋁芯表(biao)面(mian)(mian)應該(gai)具有(you)金(jin)屬光(guang)澤，表(biao)面(mian)(mian)發黑(hei)的(de)銅或表(biao)面(mian)(mian)發白的(de)鋁說(shuo)明已被氧(yang)化(hua)。

第(di)三、在購買電(dian)線(xian)時應注意查看質(zhi)(zhi)量合(he)格證書。如果電(dian)線(xian)的(de)質(zhi)(zhi)量合(he)格，那么其(qi)電(dian)線(xian)質(zhi)(zhi)量應該也受過檢驗(yan)，不會(hui)有太(tai)大(da)的(de)問題(ti)。
