不合格(ge)電線電纜的危(wei)害

電線電纜(lan)是用于(yu)傳輸(shu)電力(li)、傳輸(shu)信息和實(shi)現電磁(ci)能量轉換(huan)的一(yi)大類電工產品。在抽查過程中(zhong)，發現了(le)大量的不(bu)合格產品，這(zhe)些劣質產品給電力(li)系統正常運行埋下諸多隱患。

1、標(biao)(biao)志不合(he)格(ge)(ge)的電線(xian)電纜。標(biao)(biao)志是(shi)電線(xian)電纜使用識別產(chan)(chan)品(pin)(pin)基本(ben)信(xin)息的主(zhu)要途(tu)徑，根據標(biao)(biao)準(zhun)規定標(biao)(biao)志的主(zhu)要內(nei)容是(shi)：產(chan)(chan)品(pin)(pin)型號、規格(ge)(ge)、標(biao)(biao)準(zhun)號、廠名(ming)、產(chan)(chan)地(di)等在一定的標(biao)(biao)示間距(ju)內(nei)，當標(biao)(biao)志不合(he)格(ge)(ge)時，會(hui)造成施工(gong)人(ren)員識別錯(cuo)誤，嚴重(zhong)時會(hui)引發電氣(qi)事(shi)故。

2、結構(gou)尺寸不(bu)(bu)合格的(de)電(dian)(dian)(dian)線(xian)(xian)電(dian)(dian)(dian)纜。結構(gou)尺寸的(de)主要問題是護(hu)套(tao)(tao)厚度，絕緣(yuan)厚度，當電(dian)(dian)(dian)纜的(de)護(hu)套(tao)(tao)和絕緣(yuan)厚度不(bu)(bu)達標時，致使電(dian)(dian)(dian)線(xian)(xian)電(dian)(dian)(dian)纜耐電(dian)(dian)(dian)氣強度會嚴重降低，導致電(dian)(dian)(dian)線(xian)(xian)電(dian)(dian)(dian)纜的(de)使用壽命縮短(duan)，嚴重時可導致電(dian)(dian)(dian)線(xian)(xian)電(dian)(dian)(dian)纜被擊穿(chuan)，絕緣(yuan)（護(hu)套(tao)(tao)）層(ceng)起不(bu)(bu)到正常保護(hu)作用，從而發生電(dian)(dian)(dian)氣短(duan)路和火(huo)災等現(xian)象。

3、護套式(shi)絕(jue)緣(yuan)老化前的(de)(de)(de)抗張強(qiang)度、伸(shen)長(chang)率合(he)(he)格(ge)的(de)(de)(de)電(dian)線(xian)電(dian)纜。絕(jue)緣(yuan)護套老化前的(de)(de)(de)抗張強(qiang)度、伸(shen)長(chang)率不合(he)(he)格(ge)直接大大縮(suo)短(duan)電(dian)線(xian)電(dian)纜的(de)(de)(de)工作用壽命，而且(qie)在施工或(huo)在長(chang)時間通電(dian)且(qie)溫(wen)度較高的(de)(de)(de)環(huan)境(jing)中(zhong)，極易出現絕(jue)緣(yuan)體(ti)斷(duan)裂，致使帶電(dian)導(dao)體(ti)裸露，發(fa)生能(neng)觸電(dian)式(shi)短(duan)路危險。其不合(he)(he)格(ge)的(de)(de)(de)主要原因是使用了再生料生產(chan)，以降低產(chan)品成(cheng)本，二(er)是不具備生產(chan)資格(ge)小型企業。

4、導(dao)體(ti)電(dian)(dian)(dian)(dian)阻(zu)不合(he)格的(de)(de)(de)電(dian)(dian)(dian)(dian)線(xian)。導(dao)體(ti)電(dian)(dian)(dian)(dian)阻(zu)主(zhu)要是考核電(dian)(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)(dian)纜(lan)(lan)(lan)的(de)(de)(de)導(dao)體(ti)材料(liao)以(yi)及(ji)截面(mian)是否符合(he)的(de)(de)(de)重(zhong)(zhong)要指標(biao)。當導(dao)體(ti)電(dian)(dian)(dian)(dian)阻(zu)超(chao)標(biao)時(shi)，就增大了電(dian)(dian)(dian)(dian)流在線(xian)路上通過(guo)時(shi)的(de)(de)(de)損耗，加(jia)劇了電(dian)(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)(dian)纜(lan)(lan)(lan)的(de)(de)(de)發(fa)熱。導(dao)體(ti)電(dian)(dian)(dian)(dian)阻(zu)不合(he)格的(de)(de)(de)原(yuan)因，主(zhu)要進(jin)企業為了降低成(cheng)(cheng)本(ben)，將占原(yuan)材料(liao)成(cheng)(cheng)本(ben)80%的(de)(de)(de)銅材縮水，要么降低導(dao)體(ti)的(de)(de)(de)截面(mian)積，要么使(shi)用含雜(za)質過(guo)高的(de)(de)(de)再生銅，這(zhe)樣致使(shi)電(dian)(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)(dian)纜(lan)(lan)(lan)的(de)(de)(de)導(dao)體(ti)電(dian)(dian)(dian)(dian)阻(zu)嚴重(zhong)(zhong)超(chao)標(biao)，在使(shi)用過(guo)程(cheng)中(zhong)除(chu)易引發(fa)火(huo)災(zai)，還會(hui)加(jia)速包(bao)覆在電(dian)(dian)(dian)(dian)線(xian)外的(de)(de)(de)絕緣層的(de)(de)(de)老化。

在(zai)購買(mai)電(dian)線電(dian)纜的(de)過程中，消費(fei)者應注意以下幾個事

第(di)一(yi)、要觀察電(dian)線的(de)外觀。合格產品的(de)絕緣（護套）層(ceng)柔軟、有韌性(xing)和伸縮性(xing)、表面層(ceng)緊密、光滑(hua)、無粗糙感(gan)。如果包裹電(dian)線的(de)塑(su)料(liao)很容易(yi)被剝(bo)去，則存在塑(su)料(liao)強度(du)不夠(gou)的(de)問題。

第二、要看電線的(de)截面(mian)。合格產品的(de)銅(tong)芯或鋁芯表(biao)面(mian)應該具(ju)有(you)金(jin)屬光澤，表(biao)面(mian)發黑的(de)銅(tong)或表(biao)面(mian)發白的(de)鋁說(shuo)明已(yi)被氧化(hua)。

第三、在購買(mai)電線(xian)時應注意查看(kan)質量合(he)格(ge)證書(shu)。如果電線(xian)的質量合(he)格(ge)，那么其電線(xian)質量應該也受(shou)過檢驗，不會有太大的問題。
