不合格電(dian)線電(dian)纜的危害

電(dian)(dian)線電(dian)(dian)纜是用于傳輸(shu)電(dian)(dian)力、傳輸(shu)信息和實現(xian)(xian)電(dian)(dian)磁能量轉換的一大(da)類(lei)電(dian)(dian)工產(chan)(chan)品。在抽查過(guo)程中，發現(xian)(xian)了(le)大(da)量的不合(he)格產(chan)(chan)品，這些劣質產(chan)(chan)品給電(dian)(dian)力系統正常運(yun)行埋下諸(zhu)多隱患。

1、標(biao)(biao)(biao)(biao)(biao)志(zhi)不合(he)格的(de)電線電纜(lan)。標(biao)(biao)(biao)(biao)(biao)志(zhi)是電線電纜(lan)使用識別產(chan)品基本信(xin)息的(de)主(zhu)要途徑，根據標(biao)(biao)(biao)(biao)(biao)準(zhun)規定標(biao)(biao)(biao)(biao)(biao)志(zhi)的(de)主(zhu)要內(nei)容是：產(chan)品型號(hao)、規格、標(biao)(biao)(biao)(biao)(biao)準(zhun)號(hao)、廠名、產(chan)地等在一(yi)定的(de)標(biao)(biao)(biao)(biao)(biao)示間距內(nei)，當標(biao)(biao)(biao)(biao)(biao)志(zhi)不合(he)格時(shi)，會(hui)造成施工人員識別錯誤，嚴重時(shi)會(hui)引發(fa)電氣事故。

2、結構尺(chi)寸不(bu)合格的電(dian)(dian)線電(dian)(dian)纜。結構尺(chi)寸的主(zhu)要問題是護(hu)套(tao)(tao)厚(hou)(hou)度(du)，絕(jue)緣厚(hou)(hou)度(du)，當電(dian)(dian)纜的護(hu)套(tao)(tao)和絕(jue)緣厚(hou)(hou)度(du)不(bu)達(da)標時，致(zhi)使電(dian)(dian)線電(dian)(dian)纜耐電(dian)(dian)氣強度(du)會嚴重(zhong)(zhong)降低，導致(zhi)電(dian)(dian)線電(dian)(dian)纜的使用(yong)(yong)壽命(ming)縮短(duan)，嚴重(zhong)(zhong)時可(ke)導致(zhi)電(dian)(dian)線電(dian)(dian)纜被擊穿，絕(jue)緣（護(hu)套(tao)(tao)）層起不(bu)到(dao)正常(chang)保(bao)護(hu)作用(yong)(yong)，從而發生電(dian)(dian)氣短(duan)路和火災等現象。

3、護(hu)(hu)套(tao)式絕緣老(lao)化(hua)前(qian)的(de)(de)抗張(zhang)強(qiang)度、伸長(chang)率合格(ge)(ge)的(de)(de)電(dian)(dian)線(xian)電(dian)(dian)纜。絕緣護(hu)(hu)套(tao)老(lao)化(hua)前(qian)的(de)(de)抗張(zhang)強(qiang)度、伸長(chang)率不合格(ge)(ge)直接大大縮(suo)短電(dian)(dian)線(xian)電(dian)(dian)纜的(de)(de)工(gong)作(zuo)用(yong)壽命，而且在(zai)(zai)施工(gong)或在(zai)(zai)長(chang)時(shi)間(jian)通電(dian)(dian)且溫度較高的(de)(de)環境中(zhong)，極易出(chu)現絕緣體斷裂，致使(shi)帶電(dian)(dian)導體裸露，發生(sheng)能觸電(dian)(dian)式短路危險。其不合格(ge)(ge)的(de)(de)主要原因是使(shi)用(yong)了再生(sheng)料生(sheng)產，以降低產品(pin)成本，二(er)是不具備(bei)生(sheng)產資格(ge)(ge)小型企(qi)業。

4、導(dao)(dao)(dao)(dao)體(ti)(ti)電(dian)(dian)(dian)阻不合格(ge)的(de)(de)電(dian)(dian)(dian)線。導(dao)(dao)(dao)(dao)體(ti)(ti)電(dian)(dian)(dian)阻主要是(shi)考(kao)核電(dian)(dian)(dian)線電(dian)(dian)(dian)纜(lan)的(de)(de)導(dao)(dao)(dao)(dao)體(ti)(ti)材料以及(ji)截(jie)面(mian)是(shi)否符合的(de)(de)重要指標(biao)。當導(dao)(dao)(dao)(dao)體(ti)(ti)電(dian)(dian)(dian)阻超標(biao)時，就增大了電(dian)(dian)(dian)流在線路上通過時的(de)(de)損耗，加(jia)劇了電(dian)(dian)(dian)線電(dian)(dian)(dian)纜(lan)的(de)(de)發(fa)熱。導(dao)(dao)(dao)(dao)體(ti)(ti)電(dian)(dian)(dian)阻不合格(ge)的(de)(de)原因，主要進(jin)企業為了降(jiang)低(di)成(cheng)本，將(jiang)占(zhan)原材料成(cheng)本80%的(de)(de)銅材縮(suo)水，要么降(jiang)低(di)導(dao)(dao)(dao)(dao)體(ti)(ti)的(de)(de)截(jie)面(mian)積，要么使(shi)用含雜質過高的(de)(de)再(zai)生銅，這樣致使(shi)電(dian)(dian)(dian)線電(dian)(dian)(dian)纜(lan)的(de)(de)導(dao)(dao)(dao)(dao)體(ti)(ti)電(dian)(dian)(dian)阻嚴重超標(biao)，在使(shi)用過程中除易引(yin)發(fa)火災，還會加(jia)速包覆在電(dian)(dian)(dian)線外(wai)的(de)(de)絕(jue)緣層(ceng)的(de)(de)老化。

在購買電線電纜的過(guo)程中，消費者應注意以(yi)下幾(ji)個事(shi)

第一、要觀(guan)察電(dian)線的(de)外(wai)觀(guan)。合(he)格(ge)產品的(de)絕緣（護套）層(ceng)柔軟、有韌(ren)性和伸(shen)縮性、表(biao)面(mian)層(ceng)緊密、光滑、無(wu)粗糙感。如果包裹電(dian)線的(de)塑料很容易被(bei)剝(bo)去(qu)，則存(cun)在塑料強(qiang)度不夠的(de)問題(ti)。

第二、要看(kan)電線的截面。合格產品的銅芯或(huo)鋁芯表(biao)面應該具有金屬光澤，表(biao)面發(fa)黑的銅或(huo)表(biao)面發(fa)白的鋁說明(ming)已(yi)被氧(yang)化。

第(di)三、在購買(mai)電(dian)線(xian)時應注意(yi)查看質量合格證書。如果電(dian)線(xian)的質量合格，那么(me)其電(dian)線(xian)質量應該(gai)也受過檢驗，不會有太大(da)的問題(ti)。
