不合格(ge)電(dian)線(xian)電(dian)纜的危害

電線電纜是用于傳輸(shu)電力、傳輸(shu)信息和(he)實(shi)現電磁能量轉換(huan)的(de)一大類電工產(chan)(chan)品(pin)(pin)。在抽查過(guo)程(cheng)中(zhong)，發現了(le)大量的(de)不(bu)合格(ge)產(chan)(chan)品(pin)(pin)，這(zhe)些(xie)劣質產(chan)(chan)品(pin)(pin)給電力系統正常運行埋下諸多隱患。

1、標(biao)志(zhi)(zhi)不合格(ge)(ge)的電(dian)線(xian)電(dian)纜。標(biao)志(zhi)(zhi)是電(dian)線(xian)電(dian)纜使用識(shi)別產品基(ji)本信(xin)息的主(zhu)要途(tu)徑，根據(ju)標(biao)準(zhun)規定標(biao)志(zhi)(zhi)的主(zhu)要內容是：產品型號、規格(ge)(ge)、標(biao)準(zhun)號、廠名、產地等在一定的標(biao)示間距內，當(dang)標(biao)志(zhi)(zhi)不合格(ge)(ge)時，會(hui)造成施工(gong)人員識(shi)別錯誤(wu)，嚴重時會(hui)引發(fa)電(dian)氣事故。

2、結構(gou)尺(chi)寸不合格的(de)(de)電(dian)(dian)線(xian)(xian)(xian)電(dian)(dian)纜(lan)(lan)。結構(gou)尺(chi)寸的(de)(de)主要問(wen)題是護套(tao)厚度(du)，絕緣厚度(du)，當電(dian)(dian)纜(lan)(lan)的(de)(de)護套(tao)和(he)絕緣厚度(du)不達(da)標時，致使(shi)電(dian)(dian)線(xian)(xian)(xian)電(dian)(dian)纜(lan)(lan)耐(nai)電(dian)(dian)氣強度(du)會嚴(yan)(yan)重(zhong)降低，導致電(dian)(dian)線(xian)(xian)(xian)電(dian)(dian)纜(lan)(lan)的(de)(de)使(shi)用(yong)(yong)壽命縮短，嚴(yan)(yan)重(zhong)時可導致電(dian)(dian)線(xian)(xian)(xian)電(dian)(dian)纜(lan)(lan)被擊穿，絕緣（護套(tao)）層起不到正常保護作用(yong)(yong)，從而發生電(dian)(dian)氣短路和(he)火災等現象(xiang)。

3、護(hu)套(tao)式(shi)絕(jue)緣老(lao)化前的(de)(de)抗(kang)(kang)張強(qiang)度(du)、伸長(chang)率合(he)格(ge)(ge)的(de)(de)電線(xian)電纜(lan)。絕(jue)緣護(hu)套(tao)老(lao)化前的(de)(de)抗(kang)(kang)張強(qiang)度(du)、伸長(chang)率不(bu)(bu)(bu)合(he)格(ge)(ge)直(zhi)接大大縮短電線(xian)電纜(lan)的(de)(de)工(gong)作用(yong)壽命，而且在施工(gong)或在長(chang)時間通電且溫(wen)度(du)較(jiao)高的(de)(de)環境中，極易出(chu)現絕(jue)緣體(ti)斷裂，致(zhi)使帶電導體(ti)裸露，發生能觸電式(shi)短路危險。其不(bu)(bu)(bu)合(he)格(ge)(ge)的(de)(de)主要原因是使用(yong)了再(zai)生料生產，以降低(di)產品成(cheng)本，二(er)是不(bu)(bu)(bu)具備生產資格(ge)(ge)小型企業(ye)。

4、導(dao)(dao)(dao)(dao)體(ti)電(dian)(dian)阻不合(he)格(ge)的(de)(de)(de)(de)(de)電(dian)(dian)線。導(dao)(dao)(dao)(dao)體(ti)電(dian)(dian)阻主要(yao)是考(kao)核電(dian)(dian)線電(dian)(dian)纜的(de)(de)(de)(de)(de)導(dao)(dao)(dao)(dao)體(ti)材(cai)(cai)料以及截面(mian)是否符(fu)合(he)的(de)(de)(de)(de)(de)重要(yao)指標。當導(dao)(dao)(dao)(dao)體(ti)電(dian)(dian)阻超標時，就增大(da)了(le)電(dian)(dian)流(liu)在(zai)線路(lu)上通過時的(de)(de)(de)(de)(de)損耗，加劇了(le)電(dian)(dian)線電(dian)(dian)纜的(de)(de)(de)(de)(de)發(fa)熱。導(dao)(dao)(dao)(dao)體(ti)電(dian)(dian)阻不合(he)格(ge)的(de)(de)(de)(de)(de)原因(yin)，主要(yao)進企業為(wei)了(le)降(jiang)低(di)成本(ben)，將(jiang)占原材(cai)(cai)料成本(ben)80%的(de)(de)(de)(de)(de)銅材(cai)(cai)縮水，要(yao)么降(jiang)低(di)導(dao)(dao)(dao)(dao)體(ti)的(de)(de)(de)(de)(de)截面(mian)積，要(yao)么使用(yong)含雜質過高的(de)(de)(de)(de)(de)再生銅，這樣致使電(dian)(dian)線電(dian)(dian)纜的(de)(de)(de)(de)(de)導(dao)(dao)(dao)(dao)體(ti)電(dian)(dian)阻嚴重超標，在(zai)使用(yong)過程中除易引(yin)發(fa)火災，還(huan)會加速包(bao)覆在(zai)電(dian)(dian)線外(wai)的(de)(de)(de)(de)(de)絕緣層的(de)(de)(de)(de)(de)老化(hua)。

在購(gou)買電線電纜的過(guo)程中，消費者應注意以下幾個(ge)事(shi)

第一、要觀察(cha)電(dian)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(suo)性(xing)、表面層緊密、光滑、無粗糙感。如(ru)果包裹電(dian)線的(de)(de)塑(su)料很容易被剝去(qu)，則存在塑(su)料強度不夠(gou)的(de)(de)問題。

第二、要(yao)看電線的(de)(de)截面。合格產品的(de)(de)銅芯(xin)或鋁(lv)芯(xin)表(biao)面應該具(ju)有金(jin)屬(shu)光澤，表(biao)面發黑(hei)的(de)(de)銅或表(biao)面發白(bai)的(de)(de)鋁(lv)說(shuo)明已被氧化。

第三、在購(gou)買電(dian)線時應(ying)注意查看(kan)質量合格證書。如果電(dian)線的質量合格，那么(me)其電(dian)線質量應(ying)該也受過檢(jian)驗，不(bu)會有太大的問題(ti)。
