不合格電(dian)線電(dian)纜的(de)危害(hai)

電線電纜(lan)是用于傳(chuan)輸(shu)電力(li)、傳(chuan)輸(shu)信息(xi)和實現(xian)電磁能量轉換的(de)一(yi)大類電工產品。在抽查過程中，發現(xian)了大量的(de)不合格(ge)產品，這些劣質產品給電力(li)系統正常運(yun)行埋(mai)下(xia)諸多隱患。

1、標(biao)(biao)志(zhi)不合(he)格的(de)電(dian)線電(dian)纜(lan)。標(biao)(biao)志(zhi)是電(dian)線電(dian)纜(lan)使用識(shi)別(bie)產(chan)品基本信息的(de)主(zhu)要途徑，根據標(biao)(biao)準(zhun)規定標(biao)(biao)志(zhi)的(de)主(zhu)要內容是：產(chan)品型號、規格、標(biao)(biao)準(zhun)號、廠(chang)名、產(chan)地(di)等在一(yi)定的(de)標(biao)(biao)示間(jian)距內，當標(biao)(biao)志(zhi)不合(he)格時，會造成施工人員識(shi)別(bie)錯誤(wu)，嚴(yan)重時會引(yin)發(fa)電(dian)氣事故。

2、結構尺(chi)寸(cun)不(bu)合格的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)線電(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)(lan)。結構尺(chi)寸(cun)的(de)(de)(de)主要(yao)問題(ti)是護套厚(hou)度，絕緣厚(hou)度，當電(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)(lan)的(de)(de)(de)護套和絕緣厚(hou)度不(bu)達標(biao)時(shi)，致(zhi)使電(dian)(dian)(dian)(dian)(dian)(dian)線電(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)(lan)耐電(dian)(dian)(dian)(dian)(dian)(dian)氣(qi)強度會嚴重降低，導致(zhi)電(dian)(dian)(dian)(dian)(dian)(dian)線電(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)(lan)的(de)(de)(de)使用(yong)壽命縮短(duan)，嚴重時(shi)可導致(zhi)電(dian)(dian)(dian)(dian)(dian)(dian)線電(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)(lan)被(bei)擊穿，絕緣（護套）層起不(bu)到正常保護作用(yong)，從而發生電(dian)(dian)(dian)(dian)(dian)(dian)氣(qi)短(duan)路和火(huo)災(zai)等現象。

3、護套式(shi)絕緣(yuan)老化(hua)前(qian)的抗張(zhang)強度、伸長率合格的電(dian)線電(dian)纜(lan)。絕緣(yuan)護套老化(hua)前(qian)的抗張(zhang)強度、伸長率不合格直接大大縮短(duan)電(dian)線電(dian)纜(lan)的工(gong)(gong)作用壽(shou)命，而且在(zai)施工(gong)(gong)或(huo)在(zai)長時間通電(dian)且溫度較高的環(huan)境中，極易出現絕緣(yuan)體斷裂，致使帶(dai)電(dian)導(dao)體裸露，發生(sheng)能觸電(dian)式(shi)短(duan)路危險。其(qi)不合格的主(zhu)要原因(yin)是使用了再生(sheng)料生(sheng)產，以降低產品(pin)成本(ben)，二是不具備生(sheng)產資格小(xiao)型企(qi)業(ye)。

4、導(dao)(dao)(dao)(dao)體(ti)(ti)電(dian)(dian)(dian)(dian)阻(zu)(zu)(zu)不(bu)合格的(de)(de)電(dian)(dian)(dian)(dian)線(xian)。導(dao)(dao)(dao)(dao)體(ti)(ti)電(dian)(dian)(dian)(dian)阻(zu)(zu)(zu)主要是考(kao)核電(dian)(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)(dian)纜的(de)(de)導(dao)(dao)(dao)(dao)體(ti)(ti)材料(liao)以及截(jie)面是否符合的(de)(de)重(zhong)要指標(biao)。當導(dao)(dao)(dao)(dao)體(ti)(ti)電(dian)(dian)(dian)(dian)阻(zu)(zu)(zu)超標(biao)時，就增大了(le)電(dian)(dian)(dian)(dian)流在線(xian)路上通過(guo)時的(de)(de)損耗，加劇了(le)電(dian)(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)(dian)纜的(de)(de)發(fa)熱(re)。導(dao)(dao)(dao)(dao)體(ti)(ti)電(dian)(dian)(dian)(dian)阻(zu)(zu)(zu)不(bu)合格的(de)(de)原因，主要進企業為(wei)了(le)降(jiang)低(di)成(cheng)本，將(jiang)占原材料(liao)成(cheng)本80%的(de)(de)銅材縮水，要么(me)降(jiang)低(di)導(dao)(dao)(dao)(dao)體(ti)(ti)的(de)(de)截(jie)面積，要么(me)使用含雜質過(guo)高的(de)(de)再生銅，這樣致(zhi)使電(dian)(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)(dian)纜的(de)(de)導(dao)(dao)(dao)(dao)體(ti)(ti)電(dian)(dian)(dian)(dian)阻(zu)(zu)(zu)嚴重(zhong)超標(biao)，在使用過(guo)程中(zhong)除(chu)易引發(fa)火(huo)災，還會加速(su)包覆在電(dian)(dian)(dian)(dian)線(xian)外的(de)(de)絕緣層(ceng)的(de)(de)老化。

在(zai)購買電線(xian)電纜的過(guo)程(cheng)中(zhong)，消費者應注(zhu)意(yi)以下幾個事

第一、要觀(guan)察電線(xian)的(de)外觀(guan)。合格產品的(de)絕緣(yuan)（護套(tao)）層(ceng)柔軟、有韌(ren)性(xing)和伸縮性(xing)、表面層(ceng)緊密、光滑(hua)、無(wu)粗糙感。如果包裹電線(xian)的(de)塑料很容(rong)易被剝去(qu)，則(ze)存在(zai)塑料強度不夠的(de)問題。

第二、要看電(dian)線的(de)截(jie)面。合(he)格產品的(de)銅芯或鋁芯表面應(ying)該具有金屬光澤(ze)，表面發(fa)黑的(de)銅或表面發(fa)白的(de)鋁說明已被氧化。

第三、在(zai)購買電線(xian)(xian)時應注意(yi)查看質量合格證書。如果電線(xian)(xian)的質量合格，那么(me)其(qi)電線(xian)(xian)質量應該也受過檢驗，不會有太大的問題(ti)。
