不(bu)合格電(dian)(dian)線電(dian)(dian)纜的(de)危害(hai)

電(dian)(dian)(dian)(dian)線電(dian)(dian)(dian)(dian)纜是用(yong)于傳(chuan)輸電(dian)(dian)(dian)(dian)力、傳(chuan)輸信息和實現(xian)電(dian)(dian)(dian)(dian)磁能量轉換(huan)的一大(da)類電(dian)(dian)(dian)(dian)工(gong)產品。在抽查過程(cheng)中，發現(xian)了大(da)量的不合格產品，這些劣質產品給(gei)電(dian)(dian)(dian)(dian)力系統正(zheng)常運行埋下諸多隱患。

1、標(biao)(biao)志(zhi)(zhi)(zhi)不合格(ge)的(de)電(dian)線電(dian)纜。標(biao)(biao)志(zhi)(zhi)(zhi)是電(dian)線電(dian)纜使用(yong)識(shi)別產(chan)品基本信息的(de)主要(yao)途徑，根(gen)據(ju)標(biao)(biao)準規定(ding)標(biao)(biao)志(zhi)(zhi)(zhi)的(de)主要(yao)內容(rong)是：產(chan)品型號、規格(ge)、標(biao)(biao)準號、廠(chang)名、產(chan)地等在(zai)一定(ding)的(de)標(biao)(biao)示(shi)間距(ju)內，當標(biao)(biao)志(zhi)(zhi)(zhi)不合格(ge)時(shi)，會造成(cheng)施工人員識(shi)別錯誤(wu)，嚴(yan)重時(shi)會引發電(dian)氣(qi)事故。

2、結構尺寸不(bu)(bu)合格的(de)電(dian)(dian)線(xian)電(dian)(dian)纜(lan)(lan)。結構尺寸的(de)主要問題是護套厚度，絕緣厚度，當電(dian)(dian)纜(lan)(lan)的(de)護套和絕緣厚度不(bu)(bu)達標(biao)時，致使電(dian)(dian)線(xian)電(dian)(dian)纜(lan)(lan)耐(nai)電(dian)(dian)氣強度會嚴(yan)重降低(di)，導(dao)致電(dian)(dian)線(xian)電(dian)(dian)纜(lan)(lan)的(de)使用壽命(ming)縮短，嚴(yan)重時可導(dao)致電(dian)(dian)線(xian)電(dian)(dian)纜(lan)(lan)被擊穿，絕緣（護套）層(ceng)起不(bu)(bu)到正常(chang)保護作用，從而(er)發生(sheng)電(dian)(dian)氣短路和火災等(deng)現象。

3、護(hu)套(tao)式絕(jue)緣老(lao)化(hua)(hua)前的(de)(de)抗張強(qiang)度、伸長率(lv)合(he)格(ge)(ge)的(de)(de)電(dian)(dian)線電(dian)(dian)纜。絕(jue)緣護(hu)套(tao)老(lao)化(hua)(hua)前的(de)(de)抗張強(qiang)度、伸長率(lv)不(bu)合(he)格(ge)(ge)直接大大縮(suo)短(duan)電(dian)(dian)線電(dian)(dian)纜的(de)(de)工作用(yong)壽(shou)命，而且在施工或在長時間(jian)通電(dian)(dian)且溫(wen)度較高的(de)(de)環境(jing)中，極易出現(xian)絕(jue)緣體(ti)斷裂，致使(shi)帶電(dian)(dian)導體(ti)裸露，發生能觸電(dian)(dian)式短(duan)路危險。其不(bu)合(he)格(ge)(ge)的(de)(de)主要原因(yin)是使(shi)用(yong)了再(zai)生料生產(chan)，以降(jiang)低產(chan)品成本，二是不(bu)具備生產(chan)資格(ge)(ge)小型(xing)企業。

4、導體(ti)電(dian)(dian)(dian)阻(zu)不(bu)合格(ge)的(de)(de)電(dian)(dian)(dian)線。導體(ti)電(dian)(dian)(dian)阻(zu)主要(yao)(yao)是考(kao)核電(dian)(dian)(dian)線電(dian)(dian)(dian)纜的(de)(de)導體(ti)材料(liao)以及截面(mian)是否符合的(de)(de)重(zhong)要(yao)(yao)指標。當導體(ti)電(dian)(dian)(dian)阻(zu)超標時，就(jiu)增大(da)了(le)電(dian)(dian)(dian)流在線路上通(tong)過時的(de)(de)損(sun)耗，加(jia)劇了(le)電(dian)(dian)(dian)線電(dian)(dian)(dian)纜的(de)(de)發熱。導體(ti)電(dian)(dian)(dian)阻(zu)不(bu)合格(ge)的(de)(de)原(yuan)因，主要(yao)(yao)進企業為(wei)了(le)降(jiang)低(di)成本(ben)，將占原(yuan)材料(liao)成本(ben)80%的(de)(de)銅材縮(suo)水，要(yao)(yao)么降(jiang)低(di)導體(ti)的(de)(de)截面(mian)積(ji)，要(yao)(yao)么使用(yong)含(han)雜質過高的(de)(de)再生銅，這樣致使電(dian)(dian)(dian)線電(dian)(dian)(dian)纜的(de)(de)導體(ti)電(dian)(dian)(dian)阻(zu)嚴重(zhong)超標，在使用(yong)過程中除易(yi)引發火災，還會加(jia)速包覆在電(dian)(dian)(dian)線外的(de)(de)絕緣(yuan)層的(de)(de)老(lao)化。

在購買電(dian)線(xian)電(dian)纜的(de)過程中，消費(fei)者應注意以下幾個事(shi)

第(di)一、要觀察電(dian)線的(de)外觀。合格(ge)產品的(de)絕緣(yuan)（護套）層(ceng)(ceng)柔(rou)軟、有韌性(xing)和伸縮性(xing)、表面層(ceng)(ceng)緊密、光滑、無粗糙感。如果包裹電(dian)線的(de)塑(su)料很容易被剝去，則存在塑(su)料強度不(bu)夠(gou)的(de)問題。

第(di)二(er)、要看電(dian)線的截面。合格產(chan)品的銅芯或鋁芯表(biao)(biao)面應該(gai)具有(you)金屬(shu)光澤，表(biao)(biao)面發黑的銅或表(biao)(biao)面發白的鋁說明已被氧(yang)化。

第三、在購(gou)買電線時應注意查看質量合格證書。如(ru)果電線的質量合格，那么其電線質量應該(gai)也受過檢驗，不會有太大的問題。
