不合格(ge)電線電纜(lan)的危害

電(dian)線(xian)電(dian)纜是(shi)用(yong)于(yu)傳(chuan)輸(shu)電(dian)力、傳(chuan)輸(shu)信息和實現電(dian)磁(ci)能量轉換的一大類電(dian)工產(chan)品。在(zai)抽查過程中，發現了(le)大量的不合格(ge)產(chan)品，這(zhe)些(xie)劣質產(chan)品給電(dian)力系統正(zheng)常運行埋下(xia)諸多隱(yin)患(huan)。

1、標(biao)(biao)志(zhi)不(bu)合格的(de)電(dian)線電(dian)纜。標(biao)(biao)志(zhi)是(shi)電(dian)線電(dian)纜使用識(shi)別產(chan)品基本信息的(de)主(zhu)要途徑，根據標(biao)(biao)準規定標(biao)(biao)志(zhi)的(de)主(zhu)要內容是(shi)：產(chan)品型號(hao)(hao)、規格、標(biao)(biao)準號(hao)(hao)、廠(chang)名、產(chan)地等在一(yi)定的(de)標(biao)(biao)示間距內，當標(biao)(biao)志(zhi)不(bu)合格時，會(hui)造成施工人員識(shi)別錯(cuo)誤，嚴重時會(hui)引發(fa)電(dian)氣事故。

2、結構(gou)尺寸(cun)不合格的(de)電(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)纜(lan)。結構(gou)尺寸(cun)的(de)主要問題(ti)是(shi)護(hu)套(tao)厚(hou)度，絕(jue)緣厚(hou)度，當電(dian)(dian)(dian)纜(lan)的(de)護(hu)套(tao)和絕(jue)緣厚(hou)度不達標(biao)時，致(zhi)使電(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)纜(lan)耐(nai)電(dian)(dian)(dian)氣(qi)強度會嚴重降低，導(dao)致(zhi)電(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)纜(lan)的(de)使用(yong)壽命縮(suo)短，嚴重時可導(dao)致(zhi)電(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)纜(lan)被擊穿，絕(jue)緣（護(hu)套(tao)）層起不到正常保護(hu)作用(yong)，從(cong)而發生電(dian)(dian)(dian)氣(qi)短路和火災等現象。

3、護(hu)套(tao)式(shi)絕緣老化前的(de)抗(kang)張強度(du)、伸(shen)長率合格(ge)(ge)的(de)電(dian)線電(dian)纜。絕緣護(hu)套(tao)老化前的(de)抗(kang)張強度(du)、伸(shen)長率不(bu)合格(ge)(ge)直(zhi)接大大縮短(duan)電(dian)線電(dian)纜的(de)工(gong)作(zuo)用壽命，而(er)且(qie)在(zai)施工(gong)或在(zai)長時間通電(dian)且(qie)溫度(du)較高的(de)環境中，極易出現絕緣體斷裂(lie)，致使(shi)帶電(dian)導體裸(luo)露，發生能觸電(dian)式(shi)短(duan)路危險。其不(bu)合格(ge)(ge)的(de)主要(yao)原因是使(shi)用了(le)再生料生產，以降低產品成本，二(er)是不(bu)具(ju)備(bei)生產資格(ge)(ge)小型企業(ye)。

4、導(dao)體(ti)電(dian)(dian)(dian)阻(zu)不(bu)合(he)格的(de)電(dian)(dian)(dian)線(xian)(xian)。導(dao)體(ti)電(dian)(dian)(dian)阻(zu)主要(yao)是考核電(dian)(dian)(dian)線(xian)(xian)電(dian)(dian)(dian)纜的(de)導(dao)體(ti)材料(liao)以(yi)及截(jie)面(mian)是否符合(he)的(de)重要(yao)指(zhi)標。當導(dao)體(ti)電(dian)(dian)(dian)阻(zu)超(chao)標時(shi)，就(jiu)增大(da)了電(dian)(dian)(dian)流在線(xian)(xian)路(lu)上(shang)通過(guo)時(shi)的(de)損耗(hao)，加劇(ju)了電(dian)(dian)(dian)線(xian)(xian)電(dian)(dian)(dian)纜的(de)發熱。導(dao)體(ti)電(dian)(dian)(dian)阻(zu)不(bu)合(he)格的(de)原因，主要(yao)進企業為了降低(di)成本(ben)，將(jiang)占原材料(liao)成本(ben)80%的(de)銅材縮水，要(yao)么降低(di)導(dao)體(ti)的(de)截(jie)面(mian)積，要(yao)么使(shi)用(yong)(yong)含雜質過(guo)高的(de)再(zai)生銅，這樣致使(shi)電(dian)(dian)(dian)線(xian)(xian)電(dian)(dian)(dian)纜的(de)導(dao)體(ti)電(dian)(dian)(dian)阻(zu)嚴(yan)重超(chao)標，在使(shi)用(yong)(yong)過(guo)程中(zhong)除(chu)易引(yin)發火(huo)災(zai)，還會加速包覆在電(dian)(dian)(dian)線(xian)(xian)外(wai)的(de)絕緣層(ceng)的(de)老化。

在(zai)購買電線(xian)電纜的過程中，消費者應注意以(yi)下幾(ji)個事

第一、要觀察電線的(de)外(wai)觀。合格產品的(de)絕緣（護套(tao)）層柔(rou)軟、有韌性(xing)(xing)和伸(shen)縮(suo)性(xing)(xing)、表(biao)面(mian)層緊(jin)密、光滑(hua)、無粗(cu)糙感。如果(guo)包裹(guo)電線的(de)塑(su)料很容(rong)易被剝(bo)去，則存(cun)在(zai)塑(su)料強(qiang)度不夠(gou)的(de)問題。

第(di)二、要看電線(xian)的截面(mian)。合(he)格產品的銅芯(xin)(xin)或鋁芯(xin)(xin)表(biao)面(mian)應(ying)該具有金屬光澤(ze)，表(biao)面(mian)發(fa)黑(hei)的銅或表(biao)面(mian)發(fa)白的鋁說明已被氧化。

第(di)三(san)、在購買電(dian)線(xian)時應(ying)注意查看質量合(he)格(ge)證(zheng)書。如果電(dian)線(xian)的(de)(de)質量合(he)格(ge)，那(nei)么其電(dian)線(xian)質量應(ying)該也受過(guo)檢驗，不(bu)會有太大的(de)(de)問題。
