不(bu)合格電線(xian)電纜的危害

電(dian)(dian)線電(dian)(dian)纜是(shi)用于傳(chuan)輸(shu)電(dian)(dian)力、傳(chuan)輸(shu)信息和實現(xian)電(dian)(dian)磁能量(liang)轉換(huan)的一(yi)大類電(dian)(dian)工(gong)產(chan)品(pin)。在抽查過程(cheng)中(zhong)，發現(xian)了大量(liang)的不合(he)格產(chan)品(pin)，這(zhe)些劣(lie)質產(chan)品(pin)給電(dian)(dian)力系統正常運行埋下諸多隱患。

1、標(biao)志(zhi)不(bu)合格的(de)電(dian)(dian)線電(dian)(dian)纜。標(biao)志(zhi)是(shi)電(dian)(dian)線電(dian)(dian)纜使用識別(bie)產品(pin)基本(ben)信(xin)息(xi)的(de)主要途(tu)徑，根據標(biao)準(zhun)規定(ding)標(biao)志(zhi)的(de)主要內(nei)容是(shi)：產品(pin)型號、規格、標(biao)準(zhun)號、廠(chang)名、產地(di)等在一(yi)定(ding)的(de)標(biao)示(shi)間(jian)距內(nei)，當標(biao)志(zhi)不(bu)合格時(shi)，會造(zao)成(cheng)施工人員(yuan)識別(bie)錯誤，嚴重(zhong)時(shi)會引發電(dian)(dian)氣(qi)事故。

2、結構尺(chi)寸不(bu)合格的電(dian)線電(dian)纜(lan)(lan)。結構尺(chi)寸的主要問題(ti)是(shi)護套(tao)厚(hou)度，絕(jue)緣厚(hou)度，當電(dian)纜(lan)(lan)的護套(tao)和(he)絕(jue)緣厚(hou)度不(bu)達標時，致使電(dian)線電(dian)纜(lan)(lan)耐電(dian)氣強(qiang)度會(hui)嚴重(zhong)(zhong)降低(di)，導致電(dian)線電(dian)纜(lan)(lan)的使用(yong)壽命縮短，嚴重(zhong)(zhong)時可導致電(dian)線電(dian)纜(lan)(lan)被擊穿(chuan)，絕(jue)緣（護套(tao)）層起不(bu)到正常(chang)保護作用(yong)，從而發(fa)生(sheng)電(dian)氣短路(lu)和(he)火災等現(xian)象。

3、護(hu)(hu)套(tao)(tao)式絕(jue)緣老化(hua)前的(de)(de)抗(kang)張(zhang)強度(du)、伸長率(lv)合(he)格(ge)的(de)(de)電(dian)線電(dian)纜(lan)(lan)。絕(jue)緣護(hu)(hu)套(tao)(tao)老化(hua)前的(de)(de)抗(kang)張(zhang)強度(du)、伸長率(lv)不(bu)(bu)(bu)合(he)格(ge)直接(jie)大(da)大(da)縮短(duan)電(dian)線電(dian)纜(lan)(lan)的(de)(de)工(gong)作(zuo)用壽(shou)命，而且在施工(gong)或(huo)在長時間通電(dian)且溫度(du)較高的(de)(de)環境中，極易出現絕(jue)緣體(ti)(ti)斷裂，致使(shi)帶電(dian)導(dao)體(ti)(ti)裸(luo)露(lu)，發(fa)生能觸(chu)電(dian)式短(duan)路危險(xian)。其不(bu)(bu)(bu)合(he)格(ge)的(de)(de)主要原因(yin)是使(shi)用了再生料生產(chan)，以降低產(chan)品成本，二是不(bu)(bu)(bu)具備生產(chan)資格(ge)小型(xing)企業。

4、導體(ti)電(dian)(dian)(dian)阻(zu)不合格(ge)(ge)的(de)電(dian)(dian)(dian)線。導體(ti)電(dian)(dian)(dian)阻(zu)主要(yao)是(shi)考核電(dian)(dian)(dian)線電(dian)(dian)(dian)纜(lan)的(de)導體(ti)材(cai)料(liao)以(yi)及截面是(shi)否符合的(de)重(zhong)要(yao)指標(biao)。當導體(ti)電(dian)(dian)(dian)阻(zu)超標(biao)時，就增(zeng)大了(le)(le)電(dian)(dian)(dian)流在線路上通過(guo)時的(de)損(sun)耗，加劇了(le)(le)電(dian)(dian)(dian)線電(dian)(dian)(dian)纜(lan)的(de)發(fa)熱。導體(ti)電(dian)(dian)(dian)阻(zu)不合格(ge)(ge)的(de)原因，主要(yao)進企業為了(le)(le)降低成本(ben)，將占原材(cai)料(liao)成本(ben)80%的(de)銅(tong)材(cai)縮水(shui)，要(yao)么(me)降低導體(ti)的(de)截面積，要(yao)么(me)使用(yong)含雜質過(guo)高的(de)再生銅(tong)，這樣致(zhi)使電(dian)(dian)(dian)線電(dian)(dian)(dian)纜(lan)的(de)導體(ti)電(dian)(dian)(dian)阻(zu)嚴重(zhong)超標(biao)，在使用(yong)過(guo)程中除易引(yin)發(fa)火(huo)災，還會加速包覆在電(dian)(dian)(dian)線外(wai)的(de)絕緣層的(de)老化。

在(zai)購買電(dian)線電(dian)纜的(de)過(guo)程中，消費者應(ying)注意以下幾個(ge)事

第(di)一、要觀察電線(xian)的(de)外觀。合(he)格(ge)產品的(de)絕緣（護套）層(ceng)(ceng)柔軟、有韌性(xing)和伸縮性(xing)、表面層(ceng)(ceng)緊密、光滑(hua)、無(wu)粗糙(cao)感。如(ru)果(guo)包裹電線(xian)的(de)塑料很容(rong)易被剝去，則(ze)存在塑料強度(du)不夠的(de)問題。

第二、要看電線的(de)截面(mian)(mian)。合(he)格產(chan)品(pin)的(de)銅(tong)芯或鋁芯表面(mian)(mian)應該具有(you)金屬光澤，表面(mian)(mian)發黑的(de)銅(tong)或表面(mian)(mian)發白的(de)鋁說(shuo)明已被氧化。

第三、在購(gou)買電(dian)線(xian)(xian)時應(ying)注意查看(kan)質量(liang)合格證書。如果電(dian)線(xian)(xian)的質量(liang)合格，那(nei)么其電(dian)線(xian)(xian)質量(liang)應(ying)該也受(shou)過檢驗(yan)，不(bu)會有太大的問題。
