不合格電(dian)線電(dian)纜(lan)的(de)危害

電(dian)線電(dian)纜(lan)是(shi)用于(yu)傳輸(shu)電(dian)力、傳輸(shu)信(xin)息(xi)和(he)實現電(dian)磁能(neng)量(liang)轉(zhuan)換的一大類(lei)電(dian)工(gong)產品。在(zai)抽查過程中，發現了大量(liang)的不合格(ge)產品，這些劣質產品給電(dian)力系統正常(chang)運行埋下諸多隱患。

1、標(biao)(biao)志(zhi)不(bu)合格(ge)的(de)電(dian)線(xian)電(dian)纜(lan)。標(biao)(biao)志(zhi)是電(dian)線(xian)電(dian)纜(lan)使用識(shi)別(bie)(bie)產品基本信息的(de)主(zhu)要(yao)途徑，根據標(biao)(biao)準規(gui)定標(biao)(biao)志(zhi)的(de)主(zhu)要(yao)內容是：產品型號(hao)、規(gui)格(ge)、標(biao)(biao)準號(hao)、廠名、產地等(deng)在一定的(de)標(biao)(biao)示間距內，當(dang)標(biao)(biao)志(zhi)不(bu)合格(ge)時(shi)，會造(zao)成(cheng)施工(gong)人員(yuan)識(shi)別(bie)(bie)錯誤，嚴重時(shi)會引發電(dian)氣(qi)事故。

2、結(jie)(jie)構(gou)尺寸不(bu)(bu)合格的(de)(de)電(dian)(dian)(dian)(dian)線電(dian)(dian)(dian)(dian)纜。結(jie)(jie)構(gou)尺寸的(de)(de)主要問題(ti)是護(hu)套(tao)(tao)厚(hou)度，絕(jue)(jue)緣(yuan)厚(hou)度，當電(dian)(dian)(dian)(dian)纜的(de)(de)護(hu)套(tao)(tao)和絕(jue)(jue)緣(yuan)厚(hou)度不(bu)(bu)達(da)標時(shi)，致(zhi)使(shi)電(dian)(dian)(dian)(dian)線電(dian)(dian)(dian)(dian)纜耐電(dian)(dian)(dian)(dian)氣強度會(hui)嚴重(zhong)降低，導致(zhi)電(dian)(dian)(dian)(dian)線電(dian)(dian)(dian)(dian)纜的(de)(de)使(shi)用壽命縮短(duan)，嚴重(zhong)時(shi)可(ke)導致(zhi)電(dian)(dian)(dian)(dian)線電(dian)(dian)(dian)(dian)纜被擊(ji)穿，絕(jue)(jue)緣(yuan)（護(hu)套(tao)(tao)）層起不(bu)(bu)到正常保護(hu)作用，從而發生電(dian)(dian)(dian)(dian)氣短(duan)路和火災等現象。

3、護套(tao)式(shi)絕(jue)緣老(lao)化前(qian)的抗張強度、伸長率合格的電(dian)線(xian)電(dian)纜(lan)(lan)。絕(jue)緣護套(tao)老(lao)化前(qian)的抗張強度、伸長率不(bu)合格直接大大縮短(duan)電(dian)線(xian)電(dian)纜(lan)(lan)的工作(zuo)用壽命，而且在施工或在長時間通電(dian)且溫(wen)度較高的環境中，極(ji)易(yi)出現絕(jue)緣體(ti)(ti)斷裂，致使(shi)帶電(dian)導體(ti)(ti)裸露，發生能觸(chu)電(dian)式(shi)短(duan)路危險。其不(bu)合格的主要(yao)原因是(shi)使(shi)用了再生料生產(chan)，以降(jiang)低產(chan)品成本，二是(shi)不(bu)具備生產(chan)資格小(xiao)型企業。

4、導(dao)(dao)體(ti)(ti)(ti)電(dian)(dian)(dian)(dian)(dian)阻(zu)不(bu)合格的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)線(xian)(xian)。導(dao)(dao)體(ti)(ti)(ti)電(dian)(dian)(dian)(dian)(dian)阻(zu)主(zhu)要(yao)(yao)是(shi)考核(he)電(dian)(dian)(dian)(dian)(dian)線(xian)(xian)電(dian)(dian)(dian)(dian)(dian)纜的(de)(de)(de)導(dao)(dao)體(ti)(ti)(ti)材料(liao)以(yi)及截(jie)面(mian)是(shi)否符合的(de)(de)(de)重要(yao)(yao)指標。當導(dao)(dao)體(ti)(ti)(ti)電(dian)(dian)(dian)(dian)(dian)阻(zu)超標時(shi)，就增大了(le)電(dian)(dian)(dian)(dian)(dian)流在(zai)線(xian)(xian)路上通過時(shi)的(de)(de)(de)損(sun)耗，加劇了(le)電(dian)(dian)(dian)(dian)(dian)線(xian)(xian)電(dian)(dian)(dian)(dian)(dian)纜的(de)(de)(de)發熱。導(dao)(dao)體(ti)(ti)(ti)電(dian)(dian)(dian)(dian)(dian)阻(zu)不(bu)合格的(de)(de)(de)原(yuan)因，主(zhu)要(yao)(yao)進企業為了(le)降低(di)成(cheng)本，將占原(yuan)材料(liao)成(cheng)本80%的(de)(de)(de)銅材縮水，要(yao)(yao)么(me)降低(di)導(dao)(dao)體(ti)(ti)(ti)的(de)(de)(de)截(jie)面(mian)積，要(yao)(yao)么(me)使用含(han)雜質過高(gao)的(de)(de)(de)再生(sheng)銅，這(zhe)樣致(zhi)使電(dian)(dian)(dian)(dian)(dian)線(xian)(xian)電(dian)(dian)(dian)(dian)(dian)纜的(de)(de)(de)導(dao)(dao)體(ti)(ti)(ti)電(dian)(dian)(dian)(dian)(dian)阻(zu)嚴重超標，在(zai)使用過程(cheng)中除易引發火災，還會加速(su)包覆在(zai)電(dian)(dian)(dian)(dian)(dian)線(xian)(xian)外的(de)(de)(de)絕(jue)緣層(ceng)的(de)(de)(de)老化。

在購買電線(xian)電纜(lan)的過程中，消費者應注意以(yi)下幾個事

第一(yi)、要觀察(cha)電(dian)線的(de)外觀。合格(ge)產品的(de)絕緣（護(hu)套）層(ceng)(ceng)柔軟(ruan)、有(you)韌性(xing)和伸縮性(xing)、表面層(ceng)(ceng)緊密(mi)、光滑、無(wu)粗(cu)糙感。如果包裹電(dian)線的(de)塑料很(hen)容易被剝去，則存(cun)在(zai)塑料強度(du)不夠的(de)問題。

第二、要看電線(xian)的(de)(de)截面。合(he)格產品的(de)(de)銅芯或(huo)鋁(lv)芯表(biao)面應該具有(you)金屬光澤，表(biao)面發(fa)黑(hei)的(de)(de)銅或(huo)表(biao)面發(fa)白(bai)的(de)(de)鋁(lv)說明已被氧化。

第三(san)、在購(gou)買電(dian)(dian)線(xian)時應注意查看質(zhi)量合(he)格證書。如果電(dian)(dian)線(xian)的(de)(de)質(zhi)量合(he)格，那(nei)么其電(dian)(dian)線(xian)質(zhi)量應該(gai)也受過檢驗，不(bu)會有太大(da)的(de)(de)問題。
