不合格電線電纜的危害

電(dian)(dian)線電(dian)(dian)纜是用于傳輸電(dian)(dian)力、傳輸信息(xi)和實現(xian)電(dian)(dian)磁能量(liang)轉換的(de)一大(da)類(lei)電(dian)(dian)工產(chan)品(pin)(pin)。在抽查過程(cheng)中，發現(xian)了大(da)量(liang)的(de)不合格產(chan)品(pin)(pin)，這些劣(lie)質產(chan)品(pin)(pin)給電(dian)(dian)力系統正(zheng)常(chang)運行(xing)埋下(xia)諸多隱患。

1、標(biao)志不合格(ge)的電線電纜。標(biao)志是電線電纜使(shi)用識別產品(pin)基本信(xin)息(xi)的主要途徑，根據標(biao)準規定標(biao)志的主要內容(rong)是：產品(pin)型號(hao)、規格(ge)、標(biao)準號(hao)、廠(chang)名(ming)、產地等在(zai)一(yi)定的標(biao)示(shi)間距(ju)內，當標(biao)志不合格(ge)時(shi)，會(hui)造成施工人員識別錯(cuo)誤，嚴重時(shi)會(hui)引發電氣(qi)事(shi)故。

2、結構(gou)尺(chi)寸不合格的電(dian)(dian)(dian)(dian)(dian)線電(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)。結構(gou)尺(chi)寸的主要(yao)問題是(shi)護(hu)(hu)套(tao)(tao)厚(hou)度(du)(du)，絕(jue)緣(yuan)厚(hou)度(du)(du)，當電(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)的護(hu)(hu)套(tao)(tao)和(he)絕(jue)緣(yuan)厚(hou)度(du)(du)不達(da)標時(shi)，致(zhi)使電(dian)(dian)(dian)(dian)(dian)線電(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)耐(nai)電(dian)(dian)(dian)(dian)(dian)氣強度(du)(du)會嚴重降低，導致(zhi)電(dian)(dian)(dian)(dian)(dian)線電(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)的使用(yong)壽(shou)命縮短(duan)，嚴重時(shi)可導致(zhi)電(dian)(dian)(dian)(dian)(dian)線電(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)被擊穿，絕(jue)緣(yuan)（護(hu)(hu)套(tao)(tao)）層起不到正常(chang)保護(hu)(hu)作(zuo)用(yong)，從而發生電(dian)(dian)(dian)(dian)(dian)氣短(duan)路(lu)和(he)火災等現象(xiang)。

3、護套式(shi)絕(jue)(jue)緣老化(hua)前(qian)的(de)抗張強度、伸長(chang)(chang)(chang)率合(he)格(ge)的(de)電(dian)線電(dian)纜(lan)。絕(jue)(jue)緣護套老化(hua)前(qian)的(de)抗張強度、伸長(chang)(chang)(chang)率不合(he)格(ge)直接大(da)大(da)縮短電(dian)線電(dian)纜(lan)的(de)工作用(yong)(yong)壽命，而(er)且在施工或在長(chang)(chang)(chang)時間通電(dian)且溫度較高的(de)環境中(zhong)，極(ji)易(yi)出(chu)現絕(jue)(jue)緣體(ti)斷(duan)裂，致使帶電(dian)導(dao)體(ti)裸(luo)露，發生能觸電(dian)式(shi)短路危險。其不合(he)格(ge)的(de)主要(yao)原因是使用(yong)(yong)了再生料(liao)生產，以降低產品成本，二是不具備(bei)生產資格(ge)小(xiao)型企業。

4、導(dao)體(ti)(ti)電(dian)(dian)(dian)(dian)(dian)(dian)阻(zu)不(bu)合格的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)線(xian)(xian)(xian)(xian)。導(dao)體(ti)(ti)電(dian)(dian)(dian)(dian)(dian)(dian)阻(zu)主(zhu)要(yao)是(shi)考核電(dian)(dian)(dian)(dian)(dian)(dian)線(xian)(xian)(xian)(xian)電(dian)(dian)(dian)(dian)(dian)(dian)纜的(de)(de)(de)導(dao)體(ti)(ti)材料(liao)(liao)以及截面(mian)是(shi)否符合的(de)(de)(de)重要(yao)指標。當(dang)導(dao)體(ti)(ti)電(dian)(dian)(dian)(dian)(dian)(dian)阻(zu)超(chao)標時，就增大了(le)電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)在線(xian)(xian)(xian)(xian)路上通(tong)過時的(de)(de)(de)損耗(hao)，加劇了(le)電(dian)(dian)(dian)(dian)(dian)(dian)線(xian)(xian)(xian)(xian)電(dian)(dian)(dian)(dian)(dian)(dian)纜的(de)(de)(de)發(fa)熱。導(dao)體(ti)(ti)電(dian)(dian)(dian)(dian)(dian)(dian)阻(zu)不(bu)合格的(de)(de)(de)原因，主(zhu)要(yao)進企(qi)業為了(le)降低(di)成(cheng)本(ben)，將占原材料(liao)(liao)成(cheng)本(ben)80%的(de)(de)(de)銅(tong)材縮水，要(yao)么降低(di)導(dao)體(ti)(ti)的(de)(de)(de)截面(mian)積(ji)，要(yao)么使(shi)用含雜質過高的(de)(de)(de)再生銅(tong)，這樣致使(shi)電(dian)(dian)(dian)(dian)(dian)(dian)線(xian)(xian)(xian)(xian)電(dian)(dian)(dian)(dian)(dian)(dian)纜的(de)(de)(de)導(dao)體(ti)(ti)電(dian)(dian)(dian)(dian)(dian)(dian)阻(zu)嚴重超(chao)標，在使(shi)用過程中除易引發(fa)火(huo)災(zai)，還會加速包覆在電(dian)(dian)(dian)(dian)(dian)(dian)線(xian)(xian)(xian)(xian)外的(de)(de)(de)絕緣層的(de)(de)(de)老化(hua)。

在(zai)購買電線電纜的過程中，消(xiao)費(fei)者應(ying)注意以下幾個(ge)事

第一、要(yao)觀察電(dian)線(xian)的外觀。合格(ge)產品的絕緣（護套）層柔軟、有韌性和伸縮性、表(biao)面層緊密、光滑、無粗糙(cao)感。如(ru)果包(bao)裹電(dian)線(xian)的塑料很容易被剝去，則(ze)存(cun)在塑料強度不夠(gou)的問題(ti)。

第二(er)、要看(kan)電線的截面(mian)。合格(ge)產品的銅芯或鋁芯表面(mian)應該具有金(jin)屬(shu)光(guang)澤，表面(mian)發黑的銅或表面(mian)發白的鋁說明已(yi)被(bei)氧化。

第三、在(zai)購買電(dian)(dian)線(xian)(xian)時應注意查看(kan)質量(liang)合格(ge)證書。如果電(dian)(dian)線(xian)(xian)的質量(liang)合格(ge)，那(nei)么(me)其電(dian)(dian)線(xian)(xian)質量(liang)應該(gai)也受過檢驗，不會有太大的問題。
