不合(he)格(ge)電線電纜(lan)的危害

電(dian)線(xian)電(dian)纜(lan)是(shi)用于傳輸電(dian)力、傳輸信息和實現電(dian)磁能(neng)量(liang)轉換的一大類電(dian)工產品。在抽查(cha)過程中(zhong)，發(fa)現了(le)大量(liang)的不合格產品，這些劣(lie)質產品給電(dian)力系(xi)統正常運行埋(mai)下(xia)諸多隱患。

1、標(biao)志不合(he)格(ge)(ge)的(de)電(dian)線電(dian)纜(lan)。標(biao)志是(shi)電(dian)線電(dian)纜(lan)使用識別(bie)產(chan)品基本信(xin)息的(de)主要途徑(jing)，根據標(biao)準(zhun)規定標(biao)志的(de)主要內容是(shi)：產(chan)品型(xing)號、規格(ge)(ge)、標(biao)準(zhun)號、廠名、產(chan)地等在(zai)一(yi)定的(de)標(biao)示間距內，當標(biao)志不合(he)格(ge)(ge)時，會(hui)造成施工(gong)人員識別(bie)錯誤，嚴重時會(hui)引發電(dian)氣事故。

2、結(jie)構尺(chi)寸不(bu)合格的電(dian)(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)(dian)纜。結(jie)構尺(chi)寸的主要問題是護(hu)套厚度，絕(jue)緣(yuan)(yuan)厚度，當電(dian)(dian)(dian)(dian)纜的護(hu)套和絕(jue)緣(yuan)(yuan)厚度不(bu)達標時，致(zhi)使電(dian)(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)(dian)纜耐(nai)電(dian)(dian)(dian)(dian)氣(qi)強度會嚴重降低(di)，導致(zhi)電(dian)(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)(dian)纜的使用壽(shou)命縮(suo)短，嚴重時可(ke)導致(zhi)電(dian)(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)(dian)纜被擊(ji)穿，絕(jue)緣(yuan)(yuan)（護(hu)套）層起不(bu)到正常保護(hu)作用，從(cong)而發(fa)生電(dian)(dian)(dian)(dian)氣(qi)短路和火災等現(xian)象。

3、護(hu)套(tao)式絕(jue)緣老化(hua)前的(de)(de)抗(kang)張強度、伸長(chang)率合格的(de)(de)電線電纜。絕(jue)緣護(hu)套(tao)老化(hua)前的(de)(de)抗(kang)張強度、伸長(chang)率不(bu)合格直接大(da)大(da)縮短(duan)電線電纜的(de)(de)工(gong)(gong)作用壽命，而且(qie)在(zai)施工(gong)(gong)或(huo)在(zai)長(chang)時間通電且(qie)溫度較高的(de)(de)環境(jing)中，極易(yi)出現絕(jue)緣體斷裂，致使帶(dai)電導體裸露，發生能(neng)觸電式短(duan)路危險(xian)。其不(bu)合格的(de)(de)主要原因是(shi)(shi)使用了再(zai)生料生產(chan)(chan)，以降低產(chan)(chan)品成本，二是(shi)(shi)不(bu)具備生產(chan)(chan)資格小型(xing)企業。

4、導(dao)(dao)(dao)體(ti)(ti)電(dian)(dian)(dian)阻不(bu)合格的(de)(de)(de)(de)(de)電(dian)(dian)(dian)線(xian)(xian)(xian)。導(dao)(dao)(dao)體(ti)(ti)電(dian)(dian)(dian)阻主要(yao)(yao)是考(kao)核(he)電(dian)(dian)(dian)線(xian)(xian)(xian)電(dian)(dian)(dian)纜的(de)(de)(de)(de)(de)導(dao)(dao)(dao)體(ti)(ti)材料(liao)以及(ji)截面是否(fou)符合的(de)(de)(de)(de)(de)重要(yao)(yao)指(zhi)標。當導(dao)(dao)(dao)體(ti)(ti)電(dian)(dian)(dian)阻超標時(shi)，就增大了(le)電(dian)(dian)(dian)流在(zai)線(xian)(xian)(xian)路上通過(guo)時(shi)的(de)(de)(de)(de)(de)損耗(hao)，加劇(ju)了(le)電(dian)(dian)(dian)線(xian)(xian)(xian)電(dian)(dian)(dian)纜的(de)(de)(de)(de)(de)發(fa)熱。導(dao)(dao)(dao)體(ti)(ti)電(dian)(dian)(dian)阻不(bu)合格的(de)(de)(de)(de)(de)原因，主要(yao)(yao)進企業(ye)為了(le)降(jiang)低(di)(di)成(cheng)本(ben)，將占原材料(liao)成(cheng)本(ben)80%的(de)(de)(de)(de)(de)銅(tong)材縮水，要(yao)(yao)么(me)降(jiang)低(di)(di)導(dao)(dao)(dao)體(ti)(ti)的(de)(de)(de)(de)(de)截面積，要(yao)(yao)么(me)使(shi)用(yong)(yong)含雜質過(guo)高的(de)(de)(de)(de)(de)再生銅(tong)，這(zhe)樣致使(shi)電(dian)(dian)(dian)線(xian)(xian)(xian)電(dian)(dian)(dian)纜的(de)(de)(de)(de)(de)導(dao)(dao)(dao)體(ti)(ti)電(dian)(dian)(dian)阻嚴重超標，在(zai)使(shi)用(yong)(yong)過(guo)程中除易引(yin)發(fa)火災，還會加速包覆在(zai)電(dian)(dian)(dian)線(xian)(xian)(xian)外(wai)的(de)(de)(de)(de)(de)絕緣層的(de)(de)(de)(de)(de)老化。

在購買電(dian)線電(dian)纜的過程中，消費者應注意以下幾個事

第一、要觀(guan)察電(dian)線的外觀(guan)。合格產品的絕緣（護套(tao)）層柔軟、有韌性和伸縮性、表面(mian)層緊密、光滑、無粗糙(cao)感。如果包裹電(dian)線的塑料很容易被(bei)剝去，則存在(zai)塑料強度不夠的問題(ti)。

第(di)二、要看電線的(de)(de)截面。合格產品的(de)(de)銅芯或(huo)鋁芯表(biao)面應該(gai)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)白的(de)(de)鋁說明已被氧(yang)化(hua)。

第(di)三、在購買電線(xian)(xian)時(shi)應注意查看(kan)質量(liang)合格(ge)證(zheng)書。如(ru)果電線(xian)(xian)的(de)質量(liang)合格(ge)，那么其電線(xian)(xian)質量(liang)應該也受過檢驗，不(bu)會有(you)太大的(de)問題。
