不(bu)合格電線電纜的(de)危害

電(dian)線電(dian)纜是(shi)用(yong)于傳(chuan)輸電(dian)力、傳(chuan)輸信息和(he)實現電(dian)磁能量(liang)(liang)轉換的一(yi)大類電(dian)工(gong)產(chan)品。在抽查過程(cheng)中，發現了大量(liang)(liang)的不合格(ge)產(chan)品，這(zhe)些劣質產(chan)品給電(dian)力系統正常運行埋下諸多隱患。

1、標(biao)(biao)志(zhi)不合格的(de)電(dian)線電(dian)纜。標(biao)(biao)志(zhi)是(shi)電(dian)線電(dian)纜使用(yong)識別產品基本信(xin)息(xi)的(de)主(zhu)要(yao)(yao)途徑，根據(ju)標(biao)(biao)準規(gui)定(ding)標(biao)(biao)志(zhi)的(de)主(zhu)要(yao)(yao)內(nei)容是(shi)：產品型號、規(gui)格、標(biao)(biao)準號、廠名、產地(di)等在一定(ding)的(de)標(biao)(biao)示(shi)間(jian)距內(nei)，當標(biao)(biao)志(zhi)不合格時，會造成施工(gong)人員識別錯誤，嚴重時會引發電(dian)氣事故。

2、結構尺(chi)寸(cun)不(bu)合格的電(dian)(dian)線電(dian)(dian)纜(lan)。結構尺(chi)寸(cun)的主要(yao)問(wen)題是護(hu)(hu)套(tao)厚(hou)度(du)(du)，絕(jue)緣厚(hou)度(du)(du)，當電(dian)(dian)纜(lan)的護(hu)(hu)套(tao)和絕(jue)緣厚(hou)度(du)(du)不(bu)達(da)標(biao)時(shi)，致使(shi)電(dian)(dian)線電(dian)(dian)纜(lan)耐電(dian)(dian)氣(qi)強(qiang)度(du)(du)會(hui)嚴重(zhong)降低，導(dao)致電(dian)(dian)線電(dian)(dian)纜(lan)的使(shi)用壽命縮短，嚴重(zhong)時(shi)可導(dao)致電(dian)(dian)線電(dian)(dian)纜(lan)被擊(ji)穿(chuan)，絕(jue)緣（護(hu)(hu)套(tao)）層起(qi)不(bu)到正常保護(hu)(hu)作用，從而發生電(dian)(dian)氣(qi)短路和火災等現象。

3、護套(tao)(tao)式絕緣(yuan)老化前(qian)的(de)抗張強(qiang)度(du)、伸長(chang)率(lv)(lv)合(he)格(ge)的(de)電(dian)線電(dian)纜。絕緣(yuan)護套(tao)(tao)老化前(qian)的(de)抗張強(qiang)度(du)、伸長(chang)率(lv)(lv)不(bu)合(he)格(ge)直(zhi)接大大縮短(duan)電(dian)線電(dian)纜的(de)工(gong)作用壽(shou)命，而且(qie)(qie)在(zai)施(shi)工(gong)或在(zai)長(chang)時間(jian)通電(dian)且(qie)(qie)溫(wen)度(du)較高的(de)環境中，極易出現絕緣(yuan)體斷裂，致(zhi)使帶電(dian)導(dao)體裸露(lu)，發生能(neng)觸電(dian)式短(duan)路危險。其不(bu)合(he)格(ge)的(de)主(zhu)要原因是(shi)使用了再生料生產，以降低(di)產品成本，二是(shi)不(bu)具備(bei)生產資格(ge)小(xiao)型企業。

4、導體(ti)電(dian)(dian)阻(zu)不合(he)格的(de)(de)電(dian)(dian)線(xian)(xian)。導體(ti)電(dian)(dian)阻(zu)主(zhu)要是考核電(dian)(dian)線(xian)(xian)電(dian)(dian)纜的(de)(de)導體(ti)材料以(yi)及截面(mian)是否(fou)符合(he)的(de)(de)重要指標(biao)(biao)。當導體(ti)電(dian)(dian)阻(zu)超標(biao)(biao)時，就增(zeng)大(da)了(le)電(dian)(dian)流在線(xian)(xian)路上通過(guo)時的(de)(de)損耗，加劇(ju)了(le)電(dian)(dian)線(xian)(xian)電(dian)(dian)纜的(de)(de)發熱(re)。導體(ti)電(dian)(dian)阻(zu)不合(he)格的(de)(de)原(yuan)因，主(zhu)要進企(qi)業為了(le)降低成本，將占原(yuan)材料成本80%的(de)(de)銅材縮水，要么降低導體(ti)的(de)(de)截面(mian)積，要么使用含雜質過(guo)高的(de)(de)再(zai)生(sheng)銅，這樣致使電(dian)(dian)線(xian)(xian)電(dian)(dian)纜的(de)(de)導體(ti)電(dian)(dian)阻(zu)嚴重超標(biao)(biao)，在使用過(guo)程(cheng)中除易引發火災，還會加速包覆在電(dian)(dian)線(xian)(xian)外的(de)(de)絕緣層的(de)(de)老化。

在購(gou)買電(dian)線(xian)電(dian)纜的過(guo)程(cheng)中，消費者應注(zhu)意(yi)以下(xia)幾個事

第(di)一、要觀察電線的外觀。合(he)格產品的絕緣（護套）層柔軟(ruan)、有韌性(xing)和(he)伸縮性(xing)、表面層緊(jin)密、光滑(hua)、無粗糙感。如果包裹電線的塑料(liao)(liao)很容(rong)易被剝去，則存(cun)在(zai)塑料(liao)(liao)強度(du)不夠的問(wen)題。

第二、要看電線(xian)的(de)截面。合格產品的(de)銅芯(xin)或鋁芯(xin)表(biao)面應該具有(you)金屬光澤，表(biao)面發黑(hei)的(de)銅或表(biao)面發白的(de)鋁說明已被氧化。

第三(san)、在(zai)購(gou)買電(dian)(dian)線(xian)時應(ying)注意查看質量合(he)格(ge)證書。如(ru)果電(dian)(dian)線(xian)的(de)質量合(he)格(ge)，那么(me)其電(dian)(dian)線(xian)質量應(ying)該也受(shou)過檢(jian)驗(yan)，不會有太大的(de)問題。
