不合格電(dian)線電(dian)纜(lan)的危害

電(dian)線電(dian)纜是用于傳輸電(dian)力、傳輸信息和實現(xian)電(dian)磁能量(liang)轉換(huan)的(de)一大類電(dian)工(gong)產品。在抽(chou)查過(guo)程中(zhong)，發現(xian)了大量(liang)的(de)不(bu)合格產品，這(zhe)些劣質產品給電(dian)力系(xi)統正常運行(xing)埋下(xia)諸(zhu)多隱(yin)患。

1、標志不(bu)合(he)(he)格(ge)的(de)(de)電(dian)線(xian)電(dian)纜(lan)。標志是(shi)電(dian)線(xian)電(dian)纜(lan)使(shi)用(yong)識別產(chan)品基(ji)本信息(xi)的(de)(de)主(zhu)要途徑，根據標準(zhun)規(gui)(gui)定(ding)標志的(de)(de)主(zhu)要內容(rong)是(shi)：產(chan)品型(xing)號、規(gui)(gui)格(ge)、標準(zhun)號、廠名、產(chan)地(di)等在(zai)一定(ding)的(de)(de)標示間距內，當(dang)標志不(bu)合(he)(he)格(ge)時，會造成施工人員(yuan)識別錯誤，嚴重時會引發電(dian)氣事故(gu)。

2、結(jie)構(gou)尺寸(cun)不(bu)(bu)合(he)格(ge)的(de)電(dian)(dian)線(xian)電(dian)(dian)纜(lan)。結(jie)構(gou)尺寸(cun)的(de)主要問題是(shi)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(de)護(hu)(hu)套(tao)和絕(jue)緣厚(hou)度(du)(du)不(bu)(bu)達標時，致使電(dian)(dian)線(xian)電(dian)(dian)纜(lan)耐電(dian)(dian)氣強度(du)(du)會嚴(yan)重(zhong)降低，導致電(dian)(dian)線(xian)電(dian)(dian)纜(lan)的(de)使用(yong)壽(shou)命縮短，嚴(yan)重(zhong)時可導致電(dian)(dian)線(xian)電(dian)(dian)纜(lan)被擊穿(chuan)，絕(jue)緣（護(hu)(hu)套(tao)）層起不(bu)(bu)到正常(chang)保護(hu)(hu)作用(yong)，從(cong)而發生(sheng)電(dian)(dian)氣短路和火(huo)災等現象。

3、護(hu)套式(shi)絕(jue)緣老(lao)化前(qian)的(de)(de)抗張強(qiang)度(du)(du)(du)、伸(shen)長率合(he)(he)格(ge)的(de)(de)電(dian)(dian)(dian)線電(dian)(dian)(dian)纜。絕(jue)緣護(hu)套老(lao)化前(qian)的(de)(de)抗張強(qiang)度(du)(du)(du)、伸(shen)長率不合(he)(he)格(ge)直接大(da)大(da)縮(suo)短電(dian)(dian)(dian)線電(dian)(dian)(dian)纜的(de)(de)工作用壽命，而且(qie)在(zai)施(shi)工或(huo)在(zai)長時(shi)間通電(dian)(dian)(dian)且(qie)溫度(du)(du)(du)較高的(de)(de)環境中，極(ji)易(yi)出現絕(jue)緣體斷(duan)裂，致使(shi)帶(dai)電(dian)(dian)(dian)導體裸露，發(fa)生(sheng)能觸電(dian)(dian)(dian)式(shi)短路危險。其不合(he)(he)格(ge)的(de)(de)主要原因是(shi)使(shi)用了再生(sheng)料生(sheng)產(chan)，以降低產(chan)品成本，二是(shi)不具備生(sheng)產(chan)資格(ge)小型(xing)企業。

4、導體(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)。導體(ti)電(dian)(dian)(dian)(dian)(dian)阻(zu)主(zhu)要是(shi)考核電(dian)(dian)(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)(dian)(dian)纜(lan)的(de)(de)(de)導體(ti)材(cai)料以及截面是(shi)否符合的(de)(de)(de)重(zhong)要指(zhi)標(biao)。當(dang)導體(ti)電(dian)(dian)(dian)(dian)(dian)阻(zu)超標(biao)時(shi)，就增大了(le)電(dian)(dian)(dian)(dian)(dian)流在線(xian)路(lu)上通過時(shi)的(de)(de)(de)損耗(hao)，加劇了(le)電(dian)(dian)(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)(dian)(dian)纜(lan)的(de)(de)(de)發熱。導體(ti)電(dian)(dian)(dian)(dian)(dian)阻(zu)不(bu)合格的(de)(de)(de)原因，主(zhu)要進(jin)企業為了(le)降低成(cheng)本，將占原材(cai)料成(cheng)本80%的(de)(de)(de)銅材(cai)縮水，要么降低導體(ti)的(de)(de)(de)截面積，要么使(shi)用(yong)含雜質過高的(de)(de)(de)再生銅，這樣致(zhi)使(shi)電(dian)(dian)(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)(dian)(dian)纜(lan)的(de)(de)(de)導體(ti)電(dian)(dian)(dian)(dian)(dian)阻(zu)嚴重(zhong)超標(biao)，在使(shi)用(yong)過程中除易引發火災，還(huan)會加速包覆在電(dian)(dian)(dian)(dian)(dian)線(xian)外的(de)(de)(de)絕緣(yuan)層(ceng)的(de)(de)(de)老化(hua)。

在購買電(dian)線電(dian)纜的(de)過程中(zhong)，消費者應注(zhu)意以下幾個事

第一、要觀察電線(xian)的(de)外觀。合格產品的(de)絕(jue)緣（護套）層柔軟(ruan)、有韌性和伸(shen)縮(suo)性、表面層緊密、光滑、無(wu)粗糙感。如果(guo)包裹電線(xian)的(de)塑(su)(su)料很(hen)容易被剝(bo)去(qu)，則存在塑(su)(su)料強度不夠的(de)問題。

第二(er)、要看(kan)電(dian)線的(de)(de)(de)截面(mian)。合格產品的(de)(de)(de)銅(tong)(tong)芯(xin)或鋁芯(xin)表(biao)面(mian)應(ying)該具有(you)金屬光(guang)澤，表(biao)面(mian)發(fa)黑的(de)(de)(de)銅(tong)(tong)或表(biao)面(mian)發(fa)白的(de)(de)(de)鋁說明已被氧化。

第三、在購買電線(xian)時應(ying)注意查看(kan)質量(liang)合格證書。如果電線(xian)的質量(liang)合格，那(nei)么其(qi)電線(xian)質量(liang)應(ying)該也(ye)受(shou)過檢(jian)驗，不會(hui)有太大的問題。
