不(bu)合格(ge)電線電纜的危害

電(dian)(dian)線電(dian)(dian)纜是(shi)用于傳輸電(dian)(dian)力(li)(li)、傳輸信息和實現電(dian)(dian)磁能量轉換的一(yi)大類電(dian)(dian)工產品(pin)。在抽查(cha)過(guo)程中，發現了(le)大量的不合格(ge)產品(pin)，這些劣質產品(pin)給(gei)電(dian)(dian)力(li)(li)系統正(zheng)常(chang)運行埋下諸多隱(yin)患。

1、標(biao)(biao)志不合(he)格的(de)電(dian)線電(dian)纜。標(biao)(biao)志是(shi)(shi)電(dian)線電(dian)纜使用識別產品基本信息的(de)主(zhu)要(yao)途徑，根據標(biao)(biao)準(zhun)規(gui)定(ding)標(biao)(biao)志的(de)主(zhu)要(yao)內容是(shi)(shi)：產品型號(hao)、規(gui)格、標(biao)(biao)準(zhun)號(hao)、廠(chang)名、產地等(deng)在一定(ding)的(de)標(biao)(biao)示(shi)間距(ju)內，當標(biao)(biao)志不合(he)格時，會造成施工(gong)人員識別錯誤，嚴重時會引發(fa)電(dian)氣事故。

2、結構(gou)尺寸(cun)不合格(ge)的電(dian)(dian)(dian)(dian)線電(dian)(dian)(dian)(dian)纜。結構(gou)尺寸(cun)的主要問(wen)題是護套(tao)厚度(du)，絕(jue)緣(yuan)厚度(du)，當電(dian)(dian)(dian)(dian)纜的護套(tao)和絕(jue)緣(yuan)厚度(du)不達標時(shi)，致(zhi)(zhi)(zhi)使電(dian)(dian)(dian)(dian)線電(dian)(dian)(dian)(dian)纜耐電(dian)(dian)(dian)(dian)氣(qi)強度(du)會嚴重降低，導致(zhi)(zhi)(zhi)電(dian)(dian)(dian)(dian)線電(dian)(dian)(dian)(dian)纜的使用壽(shou)命(ming)縮短(duan)，嚴重時(shi)可(ke)導致(zhi)(zhi)(zhi)電(dian)(dian)(dian)(dian)線電(dian)(dian)(dian)(dian)纜被(bei)擊穿，絕(jue)緣(yuan)（護套(tao)）層起不到正常(chang)保護作用，從而發生電(dian)(dian)(dian)(dian)氣(qi)短(duan)路和火災(zai)等現象。

3、護套(tao)式絕(jue)緣老化(hua)前(qian)(qian)的(de)抗張強(qiang)度(du)(du)、伸長率(lv)合(he)格的(de)電線(xian)電纜。絕(jue)緣護套(tao)老化(hua)前(qian)(qian)的(de)抗張強(qiang)度(du)(du)、伸長率(lv)不(bu)合(he)格直接大大縮短(duan)(duan)電線(xian)電纜的(de)工(gong)作用壽命，而且在(zai)施工(gong)或在(zai)長時間通電且溫度(du)(du)較(jiao)高的(de)環境中，極易出現絕(jue)緣體斷裂，致(zhi)使帶(dai)電導體裸露(lu)，發生(sheng)能(neng)觸(chu)電式短(duan)(duan)路(lu)危險。其不(bu)合(he)格的(de)主要原(yuan)因是使用了(le)再生(sheng)料生(sheng)產，以降低產品成本，二(er)是不(bu)具備生(sheng)產資格小型企業。

4、導(dao)(dao)體(ti)電(dian)(dian)阻(zu)不(bu)合(he)格的(de)(de)(de)(de)電(dian)(dian)線(xian)。導(dao)(dao)體(ti)電(dian)(dian)阻(zu)主(zhu)要是(shi)考(kao)核電(dian)(dian)線(xian)電(dian)(dian)纜的(de)(de)(de)(de)導(dao)(dao)體(ti)材(cai)料以及截面(mian)是(shi)否符合(he)的(de)(de)(de)(de)重要指標(biao)。當(dang)導(dao)(dao)體(ti)電(dian)(dian)阻(zu)超(chao)標(biao)時，就(jiu)增大(da)了(le)電(dian)(dian)流在(zai)線(xian)路上通過(guo)(guo)時的(de)(de)(de)(de)損耗，加(jia)劇了(le)電(dian)(dian)線(xian)電(dian)(dian)纜的(de)(de)(de)(de)發熱。導(dao)(dao)體(ti)電(dian)(dian)阻(zu)不(bu)合(he)格的(de)(de)(de)(de)原因，主(zhu)要進企業為了(le)降低成(cheng)本，將(jiang)占原材(cai)料成(cheng)本80%的(de)(de)(de)(de)銅(tong)(tong)材(cai)縮水，要么降低導(dao)(dao)體(ti)的(de)(de)(de)(de)截面(mian)積，要么使(shi)用含(han)雜質過(guo)(guo)高(gao)的(de)(de)(de)(de)再(zai)生銅(tong)(tong)，這樣致使(shi)電(dian)(dian)線(xian)電(dian)(dian)纜的(de)(de)(de)(de)導(dao)(dao)體(ti)電(dian)(dian)阻(zu)嚴重超(chao)標(biao)，在(zai)使(shi)用過(guo)(guo)程中除易(yi)引(yin)發火(huo)災，還會加(jia)速包覆(fu)在(zai)電(dian)(dian)線(xian)外的(de)(de)(de)(de)絕緣層的(de)(de)(de)(de)老化。

在購買(mai)電線電纜的(de)過程中，消費者應注意以下幾個事

第一、要觀察電線的(de)(de)外(wai)觀。合(he)格產品的(de)(de)絕緣（護套）層(ceng)柔軟、有韌(ren)性和伸縮(suo)性、表面層(ceng)緊密、光滑、無粗(cu)糙感。如(ru)果包(bao)裹電線的(de)(de)塑(su)料很容(rong)易被剝去(qu)，則存在塑(su)料強度不夠的(de)(de)問題(ti)。

第二、要看電線的截面(mian)(mian)。合(he)格產品的銅芯或(huo)鋁芯表面(mian)(mian)應該具有(you)金(jin)屬光澤，表面(mian)(mian)發黑的銅或(huo)表面(mian)(mian)發白(bai)的鋁說明(ming)已被氧化。

第(di)三、在購買電線時應注意(yi)查(cha)看質量合格證(zheng)書。如果電線的質量合格，那么其電線質量應該也受過檢(jian)驗，不會(hui)有(you)太大的問題。
