不合格(ge)電線(xian)電纜的(de)危害

電(dian)(dian)線電(dian)(dian)纜是用(yong)于傳(chuan)輸(shu)電(dian)(dian)力(li)(li)、傳(chuan)輸(shu)信息和(he)實現電(dian)(dian)磁能量轉換的(de)(de)一(yi)大(da)類電(dian)(dian)工產品。在抽查過程(cheng)中，發現了大(da)量的(de)(de)不(bu)合(he)格產品，這些劣質產品給電(dian)(dian)力(li)(li)系統正常運行埋下諸(zhu)多(duo)隱患。

1、標(biao)(biao)志不(bu)合格的電(dian)線電(dian)纜。標(biao)(biao)志是(shi)電(dian)線電(dian)纜使用識別產品基本信息的主要途徑，根(gen)據標(biao)(biao)準規(gui)定標(biao)(biao)志的主要內(nei)容是(shi)：產品型號、規(gui)格、標(biao)(biao)準號、廠名、產地等在一定的標(biao)(biao)示間距(ju)內(nei)，當標(biao)(biao)志不(bu)合格時(shi)，會(hui)造成施工人員識別錯誤，嚴(yan)重時(shi)會(hui)引發(fa)電(dian)氣(qi)事故。

2、結構尺寸不合格(ge)的(de)電(dian)(dian)線電(dian)(dian)纜(lan)。結構尺寸的(de)主(zhu)要(yao)問題是護(hu)(hu)(hu)套(tao)厚(hou)度(du)，絕(jue)(jue)緣(yuan)厚(hou)度(du)，當電(dian)(dian)纜(lan)的(de)護(hu)(hu)(hu)套(tao)和(he)絕(jue)(jue)緣(yuan)厚(hou)度(du)不達標時，致(zhi)使電(dian)(dian)線電(dian)(dian)纜(lan)耐(nai)電(dian)(dian)氣強(qiang)度(du)會嚴重降低，導致(zhi)電(dian)(dian)線電(dian)(dian)纜(lan)的(de)使用壽命縮短，嚴重時可(ke)導致(zhi)電(dian)(dian)線電(dian)(dian)纜(lan)被擊穿，絕(jue)(jue)緣(yuan)（護(hu)(hu)(hu)套(tao)）層起不到正常保護(hu)(hu)(hu)作用，從而發生(sheng)電(dian)(dian)氣短路和(he)火災等現象。

3、護套式絕緣(yuan)老(lao)化前的抗張強度(du)(du)、伸(shen)長率合(he)格的電線電纜(lan)。絕緣(yuan)護套老(lao)化前的抗張強度(du)(du)、伸(shen)長率不(bu)合(he)格直接(jie)大大縮短電線電纜(lan)的工作用壽命(ming)，而且(qie)在施工或在長時間通電且(qie)溫(wen)度(du)(du)較高的環境中(zhong)，極易(yi)出(chu)現絕緣(yuan)體(ti)(ti)斷裂，致(zhi)使帶(dai)電導(dao)體(ti)(ti)裸露(lu)，發生(sheng)能觸電式短路危險。其不(bu)合(he)格的主要原(yuan)因是(shi)使用了再生(sheng)料生(sheng)產(chan)，以降低產(chan)品成本，二是(shi)不(bu)具備生(sheng)產(chan)資格小型企(qi)業(ye)。

4、導(dao)體(ti)(ti)(ti)電(dian)(dian)(dian)阻(zu)(zu)不合格(ge)的(de)(de)(de)(de)電(dian)(dian)(dian)線(xian)。導(dao)體(ti)(ti)(ti)電(dian)(dian)(dian)阻(zu)(zu)主(zhu)要(yao)(yao)(yao)是考(kao)核電(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)纜的(de)(de)(de)(de)導(dao)體(ti)(ti)(ti)材(cai)料以及(ji)截面是否(fou)符合的(de)(de)(de)(de)重要(yao)(yao)(yao)指標(biao)。當導(dao)體(ti)(ti)(ti)電(dian)(dian)(dian)阻(zu)(zu)超標(biao)時，就增(zeng)大了(le)電(dian)(dian)(dian)流在線(xian)路(lu)上通過時的(de)(de)(de)(de)損耗，加(jia)劇(ju)了(le)電(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)纜的(de)(de)(de)(de)發熱。導(dao)體(ti)(ti)(ti)電(dian)(dian)(dian)阻(zu)(zu)不合格(ge)的(de)(de)(de)(de)原因，主(zhu)要(yao)(yao)(yao)進企業為(wei)了(le)降低成(cheng)本，將占(zhan)原材(cai)料成(cheng)本80%的(de)(de)(de)(de)銅(tong)材(cai)縮(suo)水，要(yao)(yao)(yao)么(me)降低導(dao)體(ti)(ti)(ti)的(de)(de)(de)(de)截面積，要(yao)(yao)(yao)么(me)使用含雜質過高的(de)(de)(de)(de)再生銅(tong)，這(zhe)樣致使電(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)纜的(de)(de)(de)(de)導(dao)體(ti)(ti)(ti)電(dian)(dian)(dian)阻(zu)(zu)嚴重超標(biao)，在使用過程中除易(yi)引發火(huo)災，還(huan)會加(jia)速包覆在電(dian)(dian)(dian)線(xian)外的(de)(de)(de)(de)絕緣層的(de)(de)(de)(de)老化(hua)。

在購買電(dian)線(xian)電(dian)纜的過程中，消費者應注(zhu)意以下幾個事

第一、要觀察電線的(de)(de)外觀。合格產品的(de)(de)絕緣（護套）層柔軟、有韌性(xing)和伸縮性(xing)、表(biao)面層緊密、光(guang)滑、無粗糙(cao)感。如果包裹電線的(de)(de)塑料很容易被剝去(qu)，則存在(zai)塑料強度(du)不夠的(de)(de)問題。

第二(er)、要看電線的(de)截(jie)面。合格產品的(de)銅芯或鋁(lv)(lv)芯表(biao)面應該具有金屬光澤，表(biao)面發(fa)黑的(de)銅或表(biao)面發(fa)白的(de)鋁(lv)(lv)說明已(yi)被(bei)氧(yang)化。

第三、在購買電(dian)(dian)線(xian)時應(ying)注意查(cha)看質量(liang)合(he)格(ge)證(zheng)書(shu)。如(ru)果電(dian)(dian)線(xian)的質量(liang)合(he)格(ge)，那么(me)其(qi)電(dian)(dian)線(xian)質量(liang)應(ying)該也受過檢(jian)驗，不(bu)會有太大(da)的問題。
