不合格電線電纜的危害

電(dian)(dian)(dian)(dian)線電(dian)(dian)(dian)(dian)纜是用于傳(chuan)輸電(dian)(dian)(dian)(dian)力(li)、傳(chuan)輸信息(xi)和實現電(dian)(dian)(dian)(dian)磁能(neng)量轉(zhuan)換(huan)的一大(da)類電(dian)(dian)(dian)(dian)工產(chan)品(pin)。在(zai)抽查過程(cheng)中(zhong)，發現了大(da)量的不合格產(chan)品(pin)，這些劣質產(chan)品(pin)給電(dian)(dian)(dian)(dian)力(li)系統正常運行埋(mai)下諸多隱患。

1、標(biao)(biao)(biao)志不(bu)合(he)格的(de)(de)電(dian)線電(dian)纜。標(biao)(biao)(biao)志是電(dian)線電(dian)纜使用識別(bie)產品(pin)基本信息的(de)(de)主(zhu)要途徑，根(gen)據標(biao)(biao)(biao)準規定標(biao)(biao)(biao)志的(de)(de)主(zhu)要內容(rong)是：產品(pin)型號、規格、標(biao)(biao)(biao)準號、廠名、產地等在(zai)一定的(de)(de)標(biao)(biao)(biao)示間距內，當標(biao)(biao)(biao)志不(bu)合(he)格時(shi)，會造成施工(gong)人(ren)員識別(bie)錯誤，嚴重(zhong)時(shi)會引發電(dian)氣事故。

2、結構尺寸不合(he)格的電(dian)(dian)(dian)線(xian)(xian)電(dian)(dian)(dian)纜(lan)。結構尺寸的主要問題是護套(tao)厚(hou)度(du)，絕(jue)(jue)緣厚(hou)度(du)，當電(dian)(dian)(dian)纜(lan)的護套(tao)和絕(jue)(jue)緣厚(hou)度(du)不達標時，致使(shi)電(dian)(dian)(dian)線(xian)(xian)電(dian)(dian)(dian)纜(lan)耐(nai)電(dian)(dian)(dian)氣(qi)強度(du)會(hui)嚴(yan)重降(jiang)低(di)，導致電(dian)(dian)(dian)線(xian)(xian)電(dian)(dian)(dian)纜(lan)的使(shi)用壽命縮(suo)短(duan)，嚴(yan)重時可(ke)導致電(dian)(dian)(dian)線(xian)(xian)電(dian)(dian)(dian)纜(lan)被擊穿，絕(jue)(jue)緣（護套(tao)）層起不到正常(chang)保(bao)護作用，從而(er)發生電(dian)(dian)(dian)氣(qi)短(duan)路和火(huo)災等現象。

3、護(hu)(hu)套式(shi)(shi)絕緣老化前的抗(kang)張強度(du)、伸長率(lv)合(he)格(ge)的電(dian)(dian)線電(dian)(dian)纜。絕緣護(hu)(hu)套老化前的抗(kang)張強度(du)、伸長率(lv)不合(he)格(ge)直接大(da)大(da)縮(suo)短電(dian)(dian)線電(dian)(dian)纜的工作用壽命，而且在(zai)施工或在(zai)長時間通電(dian)(dian)且溫度(du)較高的環境中，極(ji)易出現絕緣體(ti)斷裂，致(zhi)使帶電(dian)(dian)導體(ti)裸露(lu)，發(fa)生能(neng)觸(chu)電(dian)(dian)式(shi)(shi)短路危險。其不合(he)格(ge)的主要原因是使用了再生料生產(chan)，以降低產(chan)品(pin)成(cheng)本，二是不具(ju)備生產(chan)資(zi)格(ge)小型企業。

4、導(dao)體(ti)(ti)電(dian)(dian)阻(zu)(zu)不合格的(de)(de)(de)(de)電(dian)(dian)線。導(dao)體(ti)(ti)電(dian)(dian)阻(zu)(zu)主要(yao)是考核電(dian)(dian)線電(dian)(dian)纜的(de)(de)(de)(de)導(dao)體(ti)(ti)材料以及截面(mian)是否(fou)符合的(de)(de)(de)(de)重(zhong)要(yao)指標(biao)。當(dang)導(dao)體(ti)(ti)電(dian)(dian)阻(zu)(zu)超(chao)標(biao)時，就(jiu)增大了(le)電(dian)(dian)流在(zai)線路上(shang)通過(guo)時的(de)(de)(de)(de)損耗，加(jia)劇了(le)電(dian)(dian)線電(dian)(dian)纜的(de)(de)(de)(de)發熱。導(dao)體(ti)(ti)電(dian)(dian)阻(zu)(zu)不合格的(de)(de)(de)(de)原因，主要(yao)進企業為了(le)降低成本，將(jiang)占原材料成本80%的(de)(de)(de)(de)銅(tong)材縮水(shui)，要(yao)么降低導(dao)體(ti)(ti)的(de)(de)(de)(de)截面(mian)積，要(yao)么使用含雜質過(guo)高(gao)的(de)(de)(de)(de)再生銅(tong)，這樣致使電(dian)(dian)線電(dian)(dian)纜的(de)(de)(de)(de)導(dao)體(ti)(ti)電(dian)(dian)阻(zu)(zu)嚴重(zhong)超(chao)標(biao)，在(zai)使用過(guo)程(cheng)中除易引發火災，還會(hui)加(jia)速包覆(fu)在(zai)電(dian)(dian)線外的(de)(de)(de)(de)絕緣(yuan)層的(de)(de)(de)(de)老化。

在(zai)購買電(dian)線電(dian)纜的過(guo)程中，消費(fei)者應注意(yi)以下幾個事

第一、要觀察電(dian)線的(de)外觀。合格產品的(de)絕緣（護套）層(ceng)(ceng)柔軟、有(you)韌(ren)性(xing)和(he)伸(shen)縮性(xing)、表(biao)面層(ceng)(ceng)緊密、光(guang)滑(hua)、無粗糙感。如(ru)果包裹電(dian)線的(de)塑(su)(su)料(liao)很容易被剝去，則存在塑(su)(su)料(liao)強度不夠的(de)問題。

第二、要看(kan)電線的(de)截(jie)面。合格產(chan)品(pin)的(de)銅芯(xin)或鋁芯(xin)表(biao)(biao)面應該具(ju)有(you)金(jin)屬光澤，表(biao)(biao)面發(fa)黑的(de)銅或表(biao)(biao)面發(fa)白的(de)鋁說明(ming)已(yi)被氧化。

第(di)三、在購買電線時應注意查看質(zhi)量(liang)合格證書。如果(guo)電線的質(zhi)量(liang)合格，那么(me)其(qi)電線質(zhi)量(liang)應該也受過檢驗，不會(hui)有太大的問(wen)題。
