不合(he)格電(dian)線電(dian)纜(lan)的危害

電線電纜是用于傳輸電力、傳輸信息和實現(xian)電磁能量轉(zhuan)換的一(yi)大類電工產品(pin)。在抽查過程中(zhong)，發(fa)現(xian)了大量的不合格產品(pin)，這些(xie)劣質產品(pin)給電力系統正常運行(xing)埋下諸多(duo)隱患(huan)。

1、標(biao)志不合格(ge)(ge)的(de)電線(xian)電纜。標(biao)志是電線(xian)電纜使用(yong)識別產(chan)品基本信息的(de)主(zhu)要途徑，根據標(biao)準(zhun)規定(ding)(ding)標(biao)志的(de)主(zhu)要內容是：產(chan)品型號、規格(ge)(ge)、標(biao)準(zhun)號、廠(chang)名、產(chan)地(di)等在一定(ding)(ding)的(de)標(biao)示間距內，當標(biao)志不合格(ge)(ge)時，會造成施工人員識別錯誤，嚴重時會引發(fa)電氣事故。

2、結構尺寸不合格的電(dian)(dian)(dian)線電(dian)(dian)(dian)纜(lan)(lan)。結構尺寸的主要問題是(shi)護(hu)套(tao)厚(hou)度(du)(du)，絕緣(yuan)(yuan)厚(hou)度(du)(du)，當電(dian)(dian)(dian)纜(lan)(lan)的護(hu)套(tao)和絕緣(yuan)(yuan)厚(hou)度(du)(du)不達(da)標(biao)時(shi)，致使電(dian)(dian)(dian)線電(dian)(dian)(dian)纜(lan)(lan)耐(nai)電(dian)(dian)(dian)氣強度(du)(du)會嚴重(zhong)降(jiang)低，導(dao)致電(dian)(dian)(dian)線電(dian)(dian)(dian)纜(lan)(lan)的使用壽命縮(suo)短，嚴重(zhong)時(shi)可導(dao)致電(dian)(dian)(dian)線電(dian)(dian)(dian)纜(lan)(lan)被擊穿，絕緣(yuan)(yuan)（護(hu)套(tao)）層起不到正常保護(hu)作用，從而發(fa)生電(dian)(dian)(dian)氣短路(lu)和火災等現(xian)象。

3、護套式絕緣(yuan)老化(hua)前的(de)抗(kang)張強(qiang)度、伸長率合格的(de)電(dian)線電(dian)纜(lan)。絕緣(yuan)護套老化(hua)前的(de)抗(kang)張強(qiang)度、伸長率不合格直接大大縮短電(dian)線電(dian)纜(lan)的(de)工作用(yong)壽(shou)命，而且(qie)在施工或在長時(shi)間通電(dian)且(qie)溫度較高(gao)的(de)環境中(zhong)，極易出現絕緣(yuan)體(ti)斷裂，致(zhi)使帶電(dian)導(dao)體(ti)裸露，發生(sheng)(sheng)能觸電(dian)式短路危險。其不合格的(de)主要原因是使用(yong)了再生(sheng)(sheng)料生(sheng)(sheng)產(chan)，以降(jiang)低(di)產(chan)品成本(ben)，二是不具備生(sheng)(sheng)產(chan)資格小型(xing)企(qi)業。

4、導(dao)體(ti)電(dian)(dian)(dian)阻(zu)不(bu)合(he)(he)格的(de)(de)(de)電(dian)(dian)(dian)線(xian)。導(dao)體(ti)電(dian)(dian)(dian)阻(zu)主(zhu)要(yao)是考核(he)電(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)纜(lan)的(de)(de)(de)導(dao)體(ti)材(cai)料以及截面是否符合(he)(he)的(de)(de)(de)重要(yao)指標。當(dang)導(dao)體(ti)電(dian)(dian)(dian)阻(zu)超標時，就增大了(le)電(dian)(dian)(dian)流在(zai)線(xian)路上通過(guo)時的(de)(de)(de)損耗(hao)，加劇了(le)電(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)纜(lan)的(de)(de)(de)發(fa)熱。導(dao)體(ti)電(dian)(dian)(dian)阻(zu)不(bu)合(he)(he)格的(de)(de)(de)原因，主(zhu)要(yao)進企(qi)業(ye)為(wei)了(le)降低(di)成本(ben)，將占原材(cai)料成本(ben)80%的(de)(de)(de)銅(tong)材(cai)縮水，要(yao)么(me)降低(di)導(dao)體(ti)的(de)(de)(de)截面積，要(yao)么(me)使用含雜(za)質過(guo)高(gao)的(de)(de)(de)再(zai)生銅(tong)，這樣致(zhi)使電(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)纜(lan)的(de)(de)(de)導(dao)體(ti)電(dian)(dian)(dian)阻(zu)嚴重超標，在(zai)使用過(guo)程中除(chu)易引發(fa)火災，還會加速包覆(fu)在(zai)電(dian)(dian)(dian)線(xian)外的(de)(de)(de)絕緣層的(de)(de)(de)老化。

在購買電線(xian)電纜(lan)的過程中，消費者(zhe)應注意以(yi)下幾(ji)個(ge)事

第一、要(yao)觀(guan)察電(dian)線(xian)的(de)外觀(guan)。合(he)格產品(pin)的(de)絕緣（護套）層柔軟、有韌性和伸縮性、表面層緊密、光滑(hua)、無粗糙感。如果包(bao)裹電(dian)線(xian)的(de)塑(su)料(liao)很容易被(bei)剝去，則存在塑(su)料(liao)強度不夠的(de)問題。

第二(er)、要看電(dian)線的(de)截面(mian)(mian)。合(he)格產品的(de)銅(tong)芯(xin)或(huo)鋁(lv)芯(xin)表(biao)面(mian)(mian)應該(gai)具有金屬光(guang)澤，表(biao)面(mian)(mian)發黑的(de)銅(tong)或(huo)表(biao)面(mian)(mian)發白的(de)鋁(lv)說(shuo)明已被氧化。

第三、在購買(mai)電線(xian)(xian)時應(ying)(ying)注(zhu)意查看質(zhi)量(liang)合格證書。如果(guo)電線(xian)(xian)的質(zhi)量(liang)合格，那么(me)其電線(xian)(xian)質(zhi)量(liang)應(ying)(ying)該也(ye)受(shou)過檢驗，不會有(you)太大的問題。
