不合格電(dian)線電(dian)纜的危害

電(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)纜是用于(yu)傳輸(shu)電(dian)(dian)(dian)力、傳輸(shu)信息和(he)實現(xian)電(dian)(dian)(dian)磁能(neng)量轉換的(de)一(yi)大類電(dian)(dian)(dian)工產(chan)品。在(zai)抽查過程(cheng)中(zhong)，發現(xian)了大量的(de)不合格產(chan)品，這(zhe)些劣質產(chan)品給(gei)電(dian)(dian)(dian)力系統正常運(yun)行埋下諸多隱(yin)患。

1、標(biao)(biao)志不(bu)(bu)合格(ge)的(de)電線電纜。標(biao)(biao)志是(shi)電線電纜使用識(shi)別(bie)產(chan)品基本信息的(de)主(zhu)要(yao)(yao)途徑，根據標(biao)(biao)準(zhun)規定標(biao)(biao)志的(de)主(zhu)要(yao)(yao)內容是(shi)：產(chan)品型號、規格(ge)、標(biao)(biao)準(zhun)號、廠名、產(chan)地等在一(yi)定的(de)標(biao)(biao)示間距內，當標(biao)(biao)志不(bu)(bu)合格(ge)時，會造成(cheng)施工人員識(shi)別(bie)錯誤，嚴重時會引發電氣事(shi)故(gu)。

2、結構(gou)尺寸(cun)不合格(ge)的(de)(de)電(dian)(dian)線(xian)電(dian)(dian)纜(lan)。結構(gou)尺寸(cun)的(de)(de)主要問題是護(hu)套(tao)厚(hou)度(du)，絕緣(yuan)厚(hou)度(du)，當電(dian)(dian)纜(lan)的(de)(de)護(hu)套(tao)和絕緣(yuan)厚(hou)度(du)不達標(biao)時(shi)，致(zhi)使(shi)電(dian)(dian)線(xian)電(dian)(dian)纜(lan)耐電(dian)(dian)氣強度(du)會(hui)嚴(yan)重(zhong)降低，導(dao)致(zhi)電(dian)(dian)線(xian)電(dian)(dian)纜(lan)的(de)(de)使(shi)用(yong)(yong)壽命縮短(duan)，嚴(yan)重(zhong)時(shi)可導(dao)致(zhi)電(dian)(dian)線(xian)電(dian)(dian)纜(lan)被擊穿，絕緣(yuan)（護(hu)套(tao)）層起不到(dao)正常保(bao)護(hu)作用(yong)(yong)，從而發生電(dian)(dian)氣短(duan)路和火災(zai)等現象。

3、護套式絕緣老化前的(de)抗張強度(du)、伸長率(lv)合(he)格(ge)(ge)的(de)電(dian)線(xian)電(dian)纜。絕緣護套老化前的(de)抗張強度(du)、伸長率(lv)不(bu)合(he)格(ge)(ge)直接大大縮(suo)短(duan)(duan)電(dian)線(xian)電(dian)纜的(de)工(gong)作用(yong)壽命，而且在施工(gong)或在長時間通電(dian)且溫度(du)較高的(de)環境(jing)中，極(ji)易出現絕緣體(ti)斷裂，致使帶電(dian)導體(ti)裸露，發生(sheng)能觸(chu)電(dian)式短(duan)(duan)路危險。其不(bu)合(he)格(ge)(ge)的(de)主要原(yuan)因是(shi)使用(yong)了再生(sheng)料生(sheng)產，以降(jiang)低產品成本，二是(shi)不(bu)具備生(sheng)產資格(ge)(ge)小型企業。

4、導(dao)(dao)體(ti)(ti)(ti)電(dian)(dian)阻(zu)不合格的(de)(de)電(dian)(dian)線(xian)。導(dao)(dao)體(ti)(ti)(ti)電(dian)(dian)阻(zu)主(zhu)要是(shi)考核電(dian)(dian)線(xian)電(dian)(dian)纜(lan)的(de)(de)導(dao)(dao)體(ti)(ti)(ti)材(cai)(cai)料(liao)以及截(jie)面(mian)是(shi)否符合的(de)(de)重要指標(biao)。當導(dao)(dao)體(ti)(ti)(ti)電(dian)(dian)阻(zu)超標(biao)時(shi)，就(jiu)增大了(le)(le)電(dian)(dian)流在(zai)線(xian)路上通過(guo)時(shi)的(de)(de)損耗，加(jia)劇(ju)了(le)(le)電(dian)(dian)線(xian)電(dian)(dian)纜(lan)的(de)(de)發(fa)(fa)熱。導(dao)(dao)體(ti)(ti)(ti)電(dian)(dian)阻(zu)不合格的(de)(de)原(yuan)因(yin)，主(zhu)要進企(qi)業為了(le)(le)降低成本(ben)，將占原(yuan)材(cai)(cai)料(liao)成本(ben)80%的(de)(de)銅材(cai)(cai)縮水，要么降低導(dao)(dao)體(ti)(ti)(ti)的(de)(de)截(jie)面(mian)積(ji)，要么使(shi)(shi)用(yong)(yong)含雜質過(guo)高的(de)(de)再生銅，這樣致使(shi)(shi)電(dian)(dian)線(xian)電(dian)(dian)纜(lan)的(de)(de)導(dao)(dao)體(ti)(ti)(ti)電(dian)(dian)阻(zu)嚴(yan)重超標(biao)，在(zai)使(shi)(shi)用(yong)(yong)過(guo)程中除易引發(fa)(fa)火災(zai)，還會加(jia)速包(bao)覆在(zai)電(dian)(dian)線(xian)外的(de)(de)絕(jue)緣層的(de)(de)老化。

在購(gou)買電線(xian)電纜(lan)的過程中，消費者應注意以下幾個(ge)事

第一、要(yao)觀(guan)察電線的外觀(guan)。合格產品的絕緣(yuan)（護套(tao)）層柔軟、有韌性和伸(shen)縮性、表面(mian)層緊密(mi)、光滑(hua)、無(wu)粗糙感(gan)。如果包(bao)裹(guo)電線的塑(su)料很容易被剝(bo)去(qu)，則存在(zai)塑(su)料強度不夠的問題。

第二、要(yao)看(kan)電線的(de)截(jie)面(mian)(mian)。合格產品的(de)銅芯(xin)或鋁芯(xin)表(biao)面(mian)(mian)應該具有金屬(shu)光澤，表(biao)面(mian)(mian)發黑(hei)的(de)銅或表(biao)面(mian)(mian)發白的(de)鋁說明已被氧化。

第三、在購買電線時應注意查看質量(liang)合格(ge)證書。如果電線的(de)(de)質量(liang)合格(ge)，那么其電線質量(liang)應該(gai)也受過(guo)檢(jian)驗，不會有太(tai)大的(de)(de)問題。
