不合格電線電纜的危害

電(dian)線(xian)電(dian)纜(lan)是用于(yu)傳輸電(dian)力(li)(li)、傳輸信息和實現電(dian)磁能量(liang)轉(zhuan)換的(de)一大類電(dian)工產(chan)品(pin)。在抽(chou)查過程中，發現了大量(liang)的(de)不(bu)合格(ge)產(chan)品(pin)，這些(xie)劣質產(chan)品(pin)給電(dian)力(li)(li)系統正常運行埋下諸多(duo)隱患(huan)。

1、標(biao)(biao)(biao)志(zhi)(zhi)不合格(ge)(ge)的電(dian)(dian)線電(dian)(dian)纜(lan)。標(biao)(biao)(biao)志(zhi)(zhi)是電(dian)(dian)線電(dian)(dian)纜(lan)使用識別(bie)產(chan)品基(ji)本信息的主(zhu)要途徑，根據標(biao)(biao)(biao)準規(gui)定(ding)標(biao)(biao)(biao)志(zhi)(zhi)的主(zhu)要內(nei)容(rong)是：產(chan)品型(xing)號(hao)(hao)、規(gui)格(ge)(ge)、標(biao)(biao)(biao)準號(hao)(hao)、廠名、產(chan)地等在一定(ding)的標(biao)(biao)(biao)示間距內(nei)，當(dang)標(biao)(biao)(biao)志(zhi)(zhi)不合格(ge)(ge)時(shi)，會造成(cheng)施工人員識別(bie)錯誤，嚴重(zhong)時(shi)會引發電(dian)(dian)氣事故。

2、結構尺(chi)寸(cun)(cun)不(bu)合格的(de)(de)電(dian)線電(dian)纜(lan)(lan)。結構尺(chi)寸(cun)(cun)的(de)(de)主要問題(ti)是護(hu)套(tao)厚度，絕(jue)(jue)緣(yuan)厚度，當電(dian)纜(lan)(lan)的(de)(de)護(hu)套(tao)和絕(jue)(jue)緣(yuan)厚度不(bu)達標(biao)時(shi)，致使電(dian)線電(dian)纜(lan)(lan)耐電(dian)氣強度會(hui)嚴(yan)(yan)重降低，導(dao)致電(dian)線電(dian)纜(lan)(lan)的(de)(de)使用(yong)壽命縮短，嚴(yan)(yan)重時(shi)可(ke)導(dao)致電(dian)線電(dian)纜(lan)(lan)被擊(ji)穿，絕(jue)(jue)緣(yuan)（護(hu)套(tao)）層起不(bu)到(dao)正常保護(hu)作用(yong)，從而發(fa)生電(dian)氣短路(lu)和火災等現象(xiang)。

3、護套(tao)式(shi)絕緣(yuan)老化前的(de)(de)抗張強度(du)、伸長率合格(ge)(ge)(ge)(ge)的(de)(de)電(dian)(dian)線(xian)(xian)電(dian)(dian)纜(lan)。絕緣(yuan)護套(tao)老化前的(de)(de)抗張強度(du)、伸長率不合格(ge)(ge)(ge)(ge)直接大大縮短電(dian)(dian)線(xian)(xian)電(dian)(dian)纜(lan)的(de)(de)工(gong)作用壽命(ming)，而且(qie)在(zai)施工(gong)或在(zai)長時間通(tong)電(dian)(dian)且(qie)溫(wen)度(du)較高(gao)的(de)(de)環(huan)境(jing)中，極易出現(xian)絕緣(yuan)體(ti)斷(duan)裂，致使帶電(dian)(dian)導體(ti)裸露(lu)，發生(sheng)(sheng)能觸(chu)電(dian)(dian)式(shi)短路危險。其不合格(ge)(ge)(ge)(ge)的(de)(de)主要原因是使用了(le)再(zai)生(sheng)(sheng)料生(sheng)(sheng)產，以降(jiang)低產品成本，二是不具備生(sheng)(sheng)產資(zi)格(ge)(ge)(ge)(ge)小(xiao)型企(qi)業(ye)。

4、導體(ti)(ti)電(dian)(dian)阻(zu)(zu)不(bu)合(he)格的(de)(de)(de)電(dian)(dian)線(xian)。導體(ti)(ti)電(dian)(dian)阻(zu)(zu)主要(yao)(yao)(yao)是(shi)考核電(dian)(dian)線(xian)電(dian)(dian)纜的(de)(de)(de)導體(ti)(ti)材(cai)(cai)料以及截面(mian)是(shi)否符合(he)的(de)(de)(de)重要(yao)(yao)(yao)指標(biao)(biao)。當導體(ti)(ti)電(dian)(dian)阻(zu)(zu)超標(biao)(biao)時，就增大了(le)電(dian)(dian)流在線(xian)路上通(tong)過時的(de)(de)(de)損(sun)耗，加(jia)(jia)劇了(le)電(dian)(dian)線(xian)電(dian)(dian)纜的(de)(de)(de)發熱。導體(ti)(ti)電(dian)(dian)阻(zu)(zu)不(bu)合(he)格的(de)(de)(de)原因，主要(yao)(yao)(yao)進企業為了(le)降(jiang)低成(cheng)本(ben)，將占原材(cai)(cai)料成(cheng)本(ben)80%的(de)(de)(de)銅材(cai)(cai)縮水，要(yao)(yao)(yao)么(me)降(jiang)低導體(ti)(ti)的(de)(de)(de)截面(mian)積，要(yao)(yao)(yao)么(me)使用含雜質過高的(de)(de)(de)再生銅，這樣致使電(dian)(dian)線(xian)電(dian)(dian)纜的(de)(de)(de)導體(ti)(ti)電(dian)(dian)阻(zu)(zu)嚴(yan)重超標(biao)(biao)，在使用過程中除易引發火(huo)災(zai)，還會加(jia)(jia)速包(bao)覆在電(dian)(dian)線(xian)外的(de)(de)(de)絕緣層的(de)(de)(de)老化。

在購買電(dian)線電(dian)纜的過程中，消費者應(ying)注意以下幾(ji)個事

第一、要(yao)觀(guan)察(cha)電線的外觀(guan)。合格產品的絕緣（護套）層(ceng)柔軟、有韌性(xing)和伸縮性(xing)、表面層(ceng)緊密、光滑、無粗糙感。如果(guo)包(bao)裹電線的塑料(liao)很容(rong)易被剝去，則存(cun)在(zai)塑料(liao)強度(du)不(bu)夠的問題(ti)。

第二、要看電線的(de)截面。合(he)格產品的(de)銅(tong)芯或鋁芯表(biao)面應(ying)該具有(you)金屬光澤(ze)，表(biao)面發黑的(de)銅(tong)或表(biao)面發白的(de)鋁說明(ming)已被氧化(hua)。

第三、在購買電(dian)線時(shi)應(ying)注意查看質量合(he)(he)格(ge)證書。如果電(dian)線的質量合(he)(he)格(ge)，那么其電(dian)線質量應(ying)該也受過(guo)檢驗，不會(hui)有太大的問題。
