不合格(ge)電(dian)線電(dian)纜的(de)危害

電(dian)(dian)線電(dian)(dian)纜是(shi)用于(yu)傳輸電(dian)(dian)力(li)、傳輸信息和實現(xian)電(dian)(dian)磁能量轉換的(de)一大類電(dian)(dian)工產品。在抽查(cha)過程(cheng)中，發現(xian)了大量的(de)不(bu)合(he)格(ge)產品，這些劣質產品給電(dian)(dian)力(li)系統正常(chang)運行埋下諸多隱(yin)患。

1、標(biao)志(zhi)不合格的(de)電(dian)線電(dian)纜(lan)。標(biao)志(zhi)是(shi)電(dian)線電(dian)纜(lan)使用識別(bie)產品基本信息(xi)的(de)主(zhu)要途徑，根據標(biao)準規定標(biao)志(zhi)的(de)主(zhu)要內(nei)容是(shi)：產品型號、規格、標(biao)準號、廠(chang)名、產地等在一定的(de)標(biao)示間距內(nei)，當標(biao)志(zhi)不合格時，會造(zao)成施工(gong)人員識別(bie)錯誤，嚴重時會引發電(dian)氣事(shi)故(gu)。

2、結構尺(chi)寸(cun)不(bu)合(he)格的(de)(de)電(dian)(dian)線(xian)電(dian)(dian)纜(lan)。結構尺(chi)寸(cun)的(de)(de)主要問題是(shi)護(hu)(hu)套(tao)(tao)厚(hou)(hou)度，絕(jue)緣(yuan)厚(hou)(hou)度，當電(dian)(dian)纜(lan)的(de)(de)護(hu)(hu)套(tao)(tao)和絕(jue)緣(yuan)厚(hou)(hou)度不(bu)達標(biao)時(shi)，致(zhi)(zhi)使電(dian)(dian)線(xian)電(dian)(dian)纜(lan)耐(nai)電(dian)(dian)氣強度會嚴重降低(di)，導(dao)致(zhi)(zhi)電(dian)(dian)線(xian)電(dian)(dian)纜(lan)的(de)(de)使用壽命縮短，嚴重時(shi)可導(dao)致(zhi)(zhi)電(dian)(dian)線(xian)電(dian)(dian)纜(lan)被擊穿，絕(jue)緣(yuan)（護(hu)(hu)套(tao)(tao)）層起不(bu)到正常保護(hu)(hu)作用，從而發生電(dian)(dian)氣短路(lu)和火(huo)災等現象。

3、護套式絕緣老化前的(de)(de)(de)抗(kang)張強度(du)(du)、伸長率(lv)合(he)格(ge)的(de)(de)(de)電(dian)線電(dian)纜。絕緣護套老化前的(de)(de)(de)抗(kang)張強度(du)(du)、伸長率(lv)不合(he)格(ge)直接大(da)大(da)縮短電(dian)線電(dian)纜的(de)(de)(de)工作用(yong)壽命，而且(qie)在施工或在長時(shi)間(jian)通電(dian)且(qie)溫(wen)度(du)(du)較高的(de)(de)(de)環(huan)境(jing)中(zhong)，極(ji)易出現絕緣體(ti)斷裂，致使帶電(dian)導體(ti)裸(luo)露，發生(sheng)能(neng)觸電(dian)式短路危險。其(qi)不合(he)格(ge)的(de)(de)(de)主要原(yuan)因(yin)是(shi)使用(yong)了再生(sheng)料生(sheng)產，以(yi)降低產品成本，二(er)是(shi)不具(ju)備生(sheng)產資(zi)格(ge)小型企(qi)業。

4、導(dao)體電(dian)(dian)(dian)阻(zu)不(bu)(bu)合(he)格的(de)(de)(de)電(dian)(dian)(dian)線(xian)。導(dao)體電(dian)(dian)(dian)阻(zu)主要(yao)(yao)是考(kao)核電(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)纜的(de)(de)(de)導(dao)體材料(liao)以及截面是否符(fu)合(he)的(de)(de)(de)重要(yao)(yao)指標。當導(dao)體電(dian)(dian)(dian)阻(zu)超標時，就增大了(le)(le)電(dian)(dian)(dian)流在線(xian)路上通過(guo)時的(de)(de)(de)損耗，加劇了(le)(le)電(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)纜的(de)(de)(de)發(fa)熱(re)。導(dao)體電(dian)(dian)(dian)阻(zu)不(bu)(bu)合(he)格的(de)(de)(de)原(yuan)因，主要(yao)(yao)進(jin)企業為了(le)(le)降低成本，將占原(yuan)材料(liao)成本80%的(de)(de)(de)銅材縮(suo)水，要(yao)(yao)么(me)降低導(dao)體的(de)(de)(de)截面積，要(yao)(yao)么(me)使(shi)用含雜質過(guo)高的(de)(de)(de)再生銅，這樣(yang)致(zhi)使(shi)電(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)纜的(de)(de)(de)導(dao)體電(dian)(dian)(dian)阻(zu)嚴重超標，在使(shi)用過(guo)程(cheng)中(zhong)除(chu)易引發(fa)火災，還會加速包覆在電(dian)(dian)(dian)線(xian)外的(de)(de)(de)絕緣層(ceng)的(de)(de)(de)老化。

在購買電線電纜的過程(cheng)中，消費(fei)者應注意以下幾個事

第一、要觀察電線的(de)外觀。合格產品的(de)絕(jue)緣(yuan)（護套）層柔軟、有(you)韌性和伸縮性、表面層緊密、光滑、無(wu)粗糙感(gan)。如(ru)果包裹電線的(de)塑(su)(su)料很容易被剝去，則存在塑(su)(su)料強度不夠的(de)問(wen)題。

第二(er)、要看電線的(de)截(jie)面(mian)(mian)。合格(ge)產品的(de)銅芯或鋁(lv)芯表面(mian)(mian)應(ying)該(gai)具有金屬光澤，表面(mian)(mian)發(fa)黑的(de)銅或表面(mian)(mian)發(fa)白的(de)鋁(lv)說(shuo)明(ming)已(yi)被氧化。

第(di)三、在購(gou)買電線(xian)時應(ying)注意查(cha)看質(zhi)量合(he)格(ge)證(zheng)書。如果電線(xian)的質(zhi)量合(he)格(ge)，那(nei)么(me)其電線(xian)質(zhi)量應(ying)該也受過檢(jian)驗，不會(hui)有(you)太大的問題。
