不(bu)合(he)格電(dian)線電(dian)纜的(de)危害

電(dian)(dian)(dian)線電(dian)(dian)(dian)纜(lan)是用于傳輸(shu)(shu)電(dian)(dian)(dian)力、傳輸(shu)(shu)信息(xi)和實現(xian)電(dian)(dian)(dian)磁能量(liang)(liang)轉換的一大(da)(da)類電(dian)(dian)(dian)工產(chan)(chan)品(pin)(pin)。在抽查過程中，發(fa)現(xian)了大(da)(da)量(liang)(liang)的不合格(ge)產(chan)(chan)品(pin)(pin)，這些劣(lie)質(zhi)產(chan)(chan)品(pin)(pin)給電(dian)(dian)(dian)力系統正常運行(xing)埋下諸(zhu)多隱(yin)患。

1、標(biao)志不合(he)格的(de)電線(xian)電纜。標(biao)志是(shi)電線(xian)電纜使用識(shi)別(bie)產(chan)品(pin)基本(ben)信息的(de)主(zhu)要途徑，根(gen)據標(biao)準規(gui)定(ding)標(biao)志的(de)主(zhu)要內容是(shi)：產(chan)品(pin)型號、規(gui)格、標(biao)準號、廠名、產(chan)地(di)等在一定(ding)的(de)標(biao)示(shi)間距內，當標(biao)志不合(he)格時，會造成施工人員(yuan)識(shi)別(bie)錯誤(wu)，嚴重時會引發(fa)電氣事故。

2、結(jie)構(gou)尺(chi)寸不(bu)合(he)格(ge)的(de)電(dian)(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)(dian)纜。結(jie)構(gou)尺(chi)寸的(de)主要問題是護(hu)套厚(hou)度(du)，絕緣(yuan)厚(hou)度(du)，當電(dian)(dian)(dian)(dian)纜的(de)護(hu)套和絕緣(yuan)厚(hou)度(du)不(bu)達標時(shi)，致使電(dian)(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)(dian)纜耐電(dian)(dian)(dian)(dian)氣強度(du)會嚴重降低(di)，導(dao)致電(dian)(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)(dian)纜的(de)使用壽命縮短(duan)，嚴重時(shi)可導(dao)致電(dian)(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)(dian)纜被擊穿，絕緣(yuan)（護(hu)套）層起不(bu)到正(zheng)常保護(hu)作用，從而發生電(dian)(dian)(dian)(dian)氣短(duan)路和火災等(deng)現象。

3、護(hu)套式絕(jue)(jue)緣老化前(qian)的(de)(de)(de)(de)抗張強度(du)、伸長率(lv)合(he)格(ge)的(de)(de)(de)(de)電(dian)(dian)線電(dian)(dian)纜(lan)。絕(jue)(jue)緣護(hu)套老化前(qian)的(de)(de)(de)(de)抗張強度(du)、伸長率(lv)不(bu)合(he)格(ge)直接大大縮短電(dian)(dian)線電(dian)(dian)纜(lan)的(de)(de)(de)(de)工作用(yong)壽命，而且在(zai)施工或在(zai)長時間通電(dian)(dian)且溫度(du)較高(gao)的(de)(de)(de)(de)環(huan)境中，極(ji)易出現絕(jue)(jue)緣體(ti)斷裂，致(zhi)使(shi)帶電(dian)(dian)導體(ti)裸露，發(fa)生(sheng)(sheng)能觸電(dian)(dian)式短路危險。其(qi)不(bu)合(he)格(ge)的(de)(de)(de)(de)主要原因是(shi)使(shi)用(yong)了再生(sheng)(sheng)料生(sheng)(sheng)產(chan)，以(yi)降低產(chan)品(pin)成(cheng)本，二是(shi)不(bu)具(ju)備生(sheng)(sheng)產(chan)資(zi)格(ge)小型企(qi)業。

4、導體(ti)電(dian)(dian)(dian)阻(zu)(zu)(zu)不合格的(de)(de)(de)(de)電(dian)(dian)(dian)線(xian)(xian)(xian)。導體(ti)電(dian)(dian)(dian)阻(zu)(zu)(zu)主要(yao)是考核電(dian)(dian)(dian)線(xian)(xian)(xian)電(dian)(dian)(dian)纜的(de)(de)(de)(de)導體(ti)材料(liao)以及截面(mian)是否符合的(de)(de)(de)(de)重(zhong)要(yao)指標(biao)。當導體(ti)電(dian)(dian)(dian)阻(zu)(zu)(zu)超(chao)標(biao)時(shi)，就增大了(le)電(dian)(dian)(dian)流在(zai)線(xian)(xian)(xian)路(lu)上通過時(shi)的(de)(de)(de)(de)損耗，加劇(ju)了(le)電(dian)(dian)(dian)線(xian)(xian)(xian)電(dian)(dian)(dian)纜的(de)(de)(de)(de)發熱。導體(ti)電(dian)(dian)(dian)阻(zu)(zu)(zu)不合格的(de)(de)(de)(de)原因，主要(yao)進企業為了(le)降低(di)成本，將占(zhan)原材料(liao)成本80%的(de)(de)(de)(de)銅(tong)材縮(suo)水，要(yao)么(me)降低(di)導體(ti)的(de)(de)(de)(de)截面(mian)積，要(yao)么(me)使(shi)(shi)用(yong)含雜質過高的(de)(de)(de)(de)再生銅(tong)，這樣致(zhi)使(shi)(shi)電(dian)(dian)(dian)線(xian)(xian)(xian)電(dian)(dian)(dian)纜的(de)(de)(de)(de)導體(ti)電(dian)(dian)(dian)阻(zu)(zu)(zu)嚴(yan)重(zhong)超(chao)標(biao)，在(zai)使(shi)(shi)用(yong)過程(cheng)中除(chu)易引(yin)發火(huo)災(zai)，還會加速包覆在(zai)電(dian)(dian)(dian)線(xian)(xian)(xian)外的(de)(de)(de)(de)絕緣層(ceng)的(de)(de)(de)(de)老化。

在購買電線(xian)電纜的過(guo)程中，消費者應注意以(yi)下(xia)幾個事(shi)

第一、要觀(guan)察電線的外觀(guan)。合格產品的絕緣（護套）層(ceng)柔軟、有韌性和(he)伸縮(suo)性、表(biao)面層(ceng)緊(jin)密、光滑、無(wu)粗糙感。如果包裹電線的塑料很(hen)容易被剝去，則存在塑料強度不夠(gou)的問題(ti)。

第二、要看電(dian)線的(de)(de)截面。合格產品的(de)(de)銅芯(xin)或(huo)鋁(lv)芯(xin)表面應該(gai)具有金屬光澤，表面發(fa)黑的(de)(de)銅或(huo)表面發(fa)白的(de)(de)鋁(lv)說明已被氧化。

第三、在購買(mai)電線(xian)時應(ying)注(zhu)意查看質量合(he)格證書。如果電線(xian)的質量合(he)格，那么(me)其電線(xian)質量應(ying)該也受過檢驗，不(bu)會有太大的問(wen)題。
