不合格電線電纜的(de)危(wei)害

電(dian)線電(dian)纜是用于傳輸(shu)電(dian)力、傳輸(shu)信息和實現電(dian)磁能量轉(zhuan)換的一大類電(dian)工(gong)產品。在抽(chou)查過程(cheng)中，發(fa)現了大量的不(bu)合格產品，這些(xie)劣(lie)質產品給(gei)電(dian)力系(xi)統正常運(yun)行埋下(xia)諸多隱患。

1、標(biao)(biao)志(zhi)(zhi)不(bu)合格(ge)的電線電纜。標(biao)(biao)志(zhi)(zhi)是電線電纜使用識(shi)別(bie)產品(pin)基本信息的主要途徑，根據標(biao)(biao)準規定標(biao)(biao)志(zhi)(zhi)的主要內容是：產品(pin)型號、規格(ge)、標(biao)(biao)準號、廠名、產地等在一定的標(biao)(biao)示間距(ju)內，當標(biao)(biao)志(zhi)(zhi)不(bu)合格(ge)時(shi)，會(hui)造成施工人員識(shi)別(bie)錯誤(wu)，嚴重時(shi)會(hui)引發(fa)電氣(qi)事故。

2、結(jie)構尺(chi)寸不(bu)(bu)合格的(de)電(dian)線(xian)(xian)電(dian)纜。結(jie)構尺(chi)寸的(de)主要問題(ti)是護(hu)套厚度(du)，絕(jue)緣(yuan)厚度(du)，當電(dian)纜的(de)護(hu)套和絕(jue)緣(yuan)厚度(du)不(bu)(bu)達標時，致(zhi)使(shi)電(dian)線(xian)(xian)電(dian)纜耐電(dian)氣(qi)強度(du)會(hui)嚴重(zhong)降低，導致(zhi)電(dian)線(xian)(xian)電(dian)纜的(de)使(shi)用(yong)壽命縮短，嚴重(zhong)時可(ke)導致(zhi)電(dian)線(xian)(xian)電(dian)纜被擊穿，絕(jue)緣(yuan)（護(hu)套）層(ceng)起不(bu)(bu)到正(zheng)常保護(hu)作用(yong)，從而發(fa)生電(dian)氣(qi)短路和火災等現象。

3、護套(tao)式絕緣老化前的(de)(de)(de)抗張強度、伸(shen)長率合(he)格(ge)(ge)的(de)(de)(de)電(dian)線電(dian)纜。絕緣護套(tao)老化前的(de)(de)(de)抗張強度、伸(shen)長率不合(he)格(ge)(ge)直接(jie)大(da)大(da)縮短(duan)電(dian)線電(dian)纜的(de)(de)(de)工作用壽(shou)命(ming)，而且在(zai)施工或在(zai)長時間通(tong)電(dian)且溫度較(jiao)高(gao)的(de)(de)(de)環(huan)境中，極易出(chu)現絕緣體(ti)斷(duan)裂，致使帶電(dian)導(dao)體(ti)裸露，發生能觸電(dian)式短(duan)路危險。其不合(he)格(ge)(ge)的(de)(de)(de)主要原因是(shi)使用了(le)再(zai)生料生產(chan)，以降低產(chan)品成本，二是(shi)不具備生產(chan)資格(ge)(ge)小(xiao)型企業。

4、導(dao)體(ti)(ti)電(dian)(dian)阻不(bu)(bu)合(he)格的(de)(de)電(dian)(dian)線(xian)。導(dao)體(ti)(ti)電(dian)(dian)阻主要是考核電(dian)(dian)線(xian)電(dian)(dian)纜的(de)(de)導(dao)體(ti)(ti)材(cai)料(liao)以及截面是否符合(he)的(de)(de)重(zhong)要指標。當導(dao)體(ti)(ti)電(dian)(dian)阻超(chao)標時，就增大了電(dian)(dian)流在線(xian)路上通過時的(de)(de)損耗，加劇了電(dian)(dian)線(xian)電(dian)(dian)纜的(de)(de)發熱。導(dao)體(ti)(ti)電(dian)(dian)阻不(bu)(bu)合(he)格的(de)(de)原因，主要進(jin)企業為了降(jiang)低(di)成(cheng)本(ben)，將(jiang)占原材(cai)料(liao)成(cheng)本(ben)80%的(de)(de)銅材(cai)縮水，要么降(jiang)低(di)導(dao)體(ti)(ti)的(de)(de)截面積(ji)，要么使用(yong)含雜質過高的(de)(de)再(zai)生銅，這樣致使電(dian)(dian)線(xian)電(dian)(dian)纜的(de)(de)導(dao)體(ti)(ti)電(dian)(dian)阻嚴重(zhong)超(chao)標，在使用(yong)過程中除易引發火災，還會(hui)加速(su)包(bao)覆在電(dian)(dian)線(xian)外的(de)(de)絕(jue)緣層的(de)(de)老(lao)化(hua)。

在購買電線電纜的(de)過程中，消(xiao)費者應注(zhu)意(yi)以(yi)下幾(ji)個事

第(di)一(yi)、要觀察電(dian)線的(de)外觀。合格(ge)產品的(de)絕緣（護(hu)套）層(ceng)柔軟(ruan)、有韌性和(he)伸(shen)縮性、表面層(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(qu)，則存在塑(su)料強(qiang)度不(bu)夠的(de)問題。

第二(er)、要看電線的(de)截面。合(he)格產品的(de)銅芯或鋁芯表面應該具有金屬光(guang)澤，表面發黑的(de)銅或表面發白的(de)鋁說明已被氧化(hua)。

第三(san)、在購買電(dian)線時應注(zhu)意查(cha)看質量(liang)合格(ge)證(zheng)書。如果(guo)電(dian)線的質量(liang)合格(ge)，那么其電(dian)線質量(liang)應該也(ye)受過(guo)檢驗，不(bu)會(hui)有太大的問(wen)題。
