不合格電線電纜的危害

電(dian)(dian)(dian)(dian)線電(dian)(dian)(dian)(dian)纜是用于傳輸(shu)電(dian)(dian)(dian)(dian)力(li)、傳輸(shu)信息和實現(xian)電(dian)(dian)(dian)(dian)磁能量轉(zhuan)換(huan)的一(yi)大類(lei)電(dian)(dian)(dian)(dian)工產(chan)品。在抽查過程中，發(fa)現(xian)了大量的不合格(ge)產(chan)品，這些劣質產(chan)品給電(dian)(dian)(dian)(dian)力(li)系統正(zheng)常運行(xing)埋下(xia)諸多(duo)隱患。

1、標(biao)志(zhi)(zhi)不(bu)合格的(de)電線(xian)電纜。標(biao)志(zhi)(zhi)是電線(xian)電纜使用(yong)識(shi)別(bie)產(chan)品基本信息(xi)的(de)主(zhu)要途徑，根據(ju)標(biao)準(zhun)規定標(biao)志(zhi)(zhi)的(de)主(zhu)要內(nei)容(rong)是：產(chan)品型號(hao)、規格、標(biao)準(zhun)號(hao)、廠名、產(chan)地等在一(yi)定的(de)標(biao)示間距內(nei)，當標(biao)志(zhi)(zhi)不(bu)合格時，會(hui)造成施(shi)工人(ren)員識(shi)別(bie)錯誤(wu)，嚴重(zhong)時會(hui)引發(fa)電氣事故。

2、結構(gou)尺(chi)寸不合格的電(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)纜(lan)(lan)(lan)。結構(gou)尺(chi)寸的主要問(wen)題是護套(tao)厚(hou)(hou)度(du)，絕緣厚(hou)(hou)度(du)，當電(dian)(dian)(dian)纜(lan)(lan)(lan)的護套(tao)和絕緣厚(hou)(hou)度(du)不達(da)標時(shi)，致(zhi)(zhi)使(shi)電(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)纜(lan)(lan)(lan)耐電(dian)(dian)(dian)氣強(qiang)度(du)會嚴重(zhong)降低，導致(zhi)(zhi)電(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)纜(lan)(lan)(lan)的使(shi)用壽命(ming)縮短，嚴重(zhong)時(shi)可導致(zhi)(zhi)電(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)纜(lan)(lan)(lan)被(bei)擊穿(chuan)，絕緣（護套(tao)）層起不到正常保護作用，從而發生電(dian)(dian)(dian)氣短路和火(huo)災(zai)等現象。

3、護(hu)套式絕緣老(lao)化前的抗張強度(du)、伸長率合格(ge)的電線(xian)電纜(lan)。絕緣護(hu)套老(lao)化前的抗張強度(du)、伸長率不(bu)(bu)合格(ge)直接大大縮(suo)短電線(xian)電纜(lan)的工(gong)作用(yong)壽命，而且在施工(gong)或(huo)在長時(shi)間通電且溫度(du)較高的環境中，極易出現絕緣體(ti)斷裂，致使(shi)帶電導(dao)體(ti)裸露，發生能觸電式短路危險。其不(bu)(bu)合格(ge)的主(zhu)要原因是使(shi)用(yong)了(le)再生料生產(chan)，以降(jiang)低產(chan)品成本，二是不(bu)(bu)具備生產(chan)資格(ge)小型企業。

4、導體(ti)(ti)電(dian)(dian)阻不合格的(de)(de)電(dian)(dian)線。導體(ti)(ti)電(dian)(dian)阻主要(yao)是考核(he)電(dian)(dian)線電(dian)(dian)纜(lan)的(de)(de)導體(ti)(ti)材(cai)料以及(ji)截(jie)面(mian)是否(fou)符合的(de)(de)重要(yao)指標(biao)。當(dang)導體(ti)(ti)電(dian)(dian)阻超(chao)標(biao)時(shi)，就增大(da)了(le)電(dian)(dian)流在線路上通過時(shi)的(de)(de)損耗，加(jia)劇了(le)電(dian)(dian)線電(dian)(dian)纜(lan)的(de)(de)發(fa)熱。導體(ti)(ti)電(dian)(dian)阻不合格的(de)(de)原(yuan)因，主要(yao)進企業為(wei)了(le)降(jiang)低成本，將占原(yuan)材(cai)料成本80%的(de)(de)銅材(cai)縮水，要(yao)么降(jiang)低導體(ti)(ti)的(de)(de)截(jie)面(mian)積(ji)，要(yao)么使(shi)用(yong)(yong)含雜質過高的(de)(de)再生銅，這樣致使(shi)電(dian)(dian)線電(dian)(dian)纜(lan)的(de)(de)導體(ti)(ti)電(dian)(dian)阻嚴重超(chao)標(biao)，在使(shi)用(yong)(yong)過程中除易(yi)引發(fa)火災，還會(hui)加(jia)速包覆在電(dian)(dian)線外的(de)(de)絕緣層的(de)(de)老(lao)化。

在購買電(dian)線電(dian)纜(lan)的過程中，消(xiao)費者應(ying)注(zhu)意以下幾(ji)個事

第一、要(yao)觀(guan)(guan)察電線的(de)外觀(guan)(guan)。合格(ge)產(chan)品(pin)的(de)絕緣（護套）層柔軟、有韌性(xing)和(he)伸縮性(xing)、表面層緊密、光滑、無(wu)粗糙感(gan)。如果包(bao)裹電線的(de)塑料很容易被(bei)剝(bo)去，則存在塑料強度不夠的(de)問題。

第(di)二、要(yao)看電線的截(jie)面。合(he)格產品(pin)的銅(tong)芯(xin)或鋁芯(xin)表面應該具有金屬光澤，表面發黑(hei)的銅(tong)或表面發白的鋁說明已(yi)被氧(yang)化。

第三(san)、在(zai)購買電線(xian)時應注意(yi)查看質量(liang)合(he)格證書。如果電線(xian)的質量(liang)合(he)格，那么(me)其電線(xian)質量(liang)應該也受過檢(jian)驗，不會有太大的問題。
