不合格電(dian)線電(dian)纜的危害

電(dian)線電(dian)纜是用于傳輸電(dian)力、傳輸信(xin)息(xi)和實(shi)現(xian)電(dian)磁能量轉換的(de)一(yi)大類電(dian)工(gong)產品。在抽查過程中，發(fa)現(xian)了大量的(de)不合格產品，這些劣(lie)質產品給電(dian)力系統正常運行(xing)埋下諸(zhu)多隱(yin)患。

1、標(biao)(biao)(biao)志(zhi)不合(he)格的(de)電(dian)線(xian)電(dian)纜(lan)。標(biao)(biao)(biao)志(zhi)是電(dian)線(xian)電(dian)纜(lan)使(shi)用識別產(chan)品(pin)基(ji)本信息的(de)主要途徑，根據標(biao)(biao)(biao)準(zhun)(zhun)規(gui)定(ding)標(biao)(biao)(biao)志(zhi)的(de)主要內(nei)容是：產(chan)品(pin)型(xing)號(hao)、規(gui)格、標(biao)(biao)(biao)準(zhun)(zhun)號(hao)、廠(chang)名(ming)、產(chan)地等在一定(ding)的(de)標(biao)(biao)(biao)示間距內(nei)，當標(biao)(biao)(biao)志(zhi)不合(he)格時，會(hui)造(zao)成(cheng)施(shi)工(gong)人員(yuan)識別錯(cuo)誤(wu)，嚴重時會(hui)引發(fa)電(dian)氣事故。

2、結(jie)構(gou)尺(chi)寸(cun)不(bu)(bu)合格的電(dian)(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)(dian)纜(lan)。結(jie)構(gou)尺(chi)寸(cun)的主(zhu)要問題是護套厚度(du)，絕緣(yuan)厚度(du)，當電(dian)(dian)(dian)(dian)纜(lan)的護套和絕緣(yuan)厚度(du)不(bu)(bu)達(da)標時，致(zhi)(zhi)使(shi)電(dian)(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)(dian)纜(lan)耐電(dian)(dian)(dian)(dian)氣強度(du)會嚴重降(jiang)低，導致(zhi)(zhi)電(dian)(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)(dian)纜(lan)的使(shi)用壽命縮(suo)短，嚴重時可導致(zhi)(zhi)電(dian)(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)(dian)纜(lan)被擊穿，絕緣(yuan)（護套）層(ceng)起不(bu)(bu)到正(zheng)常保護作用，從而發生電(dian)(dian)(dian)(dian)氣短路和火災等現象。

3、護(hu)套式絕緣老化前的抗(kang)張強(qiang)度、伸(shen)長(chang)率合(he)格(ge)的電(dian)(dian)線電(dian)(dian)纜(lan)。絕緣護(hu)套老化前的抗(kang)張強(qiang)度、伸(shen)長(chang)率不(bu)合(he)格(ge)直(zhi)接(jie)大大縮短電(dian)(dian)線電(dian)(dian)纜(lan)的工作(zuo)用壽命(ming)，而且在施(shi)工或(huo)在長(chang)時間通電(dian)(dian)且溫度較高的環境中，極(ji)易出現絕緣體(ti)斷裂(lie)，致(zhi)使帶電(dian)(dian)導體(ti)裸露，發生(sheng)能(neng)觸電(dian)(dian)式短路危險。其不(bu)合(he)格(ge)的主要(yao)原因(yin)是使用了(le)再生(sheng)料(liao)生(sheng)產(chan)，以降低產(chan)品成本，二是不(bu)具備生(sheng)產(chan)資(zi)格(ge)小型企業。

4、導(dao)體電(dian)(dian)(dian)阻(zu)不合格(ge)的(de)(de)(de)電(dian)(dian)(dian)線(xian)。導(dao)體電(dian)(dian)(dian)阻(zu)主要(yao)是考核電(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)纜(lan)的(de)(de)(de)導(dao)體材料(liao)(liao)以(yi)及截面(mian)是否符合的(de)(de)(de)重要(yao)指標(biao)。當導(dao)體電(dian)(dian)(dian)阻(zu)超(chao)標(biao)時(shi)，就增(zeng)大了電(dian)(dian)(dian)流在線(xian)路上通過(guo)(guo)時(shi)的(de)(de)(de)損耗，加劇(ju)了電(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)纜(lan)的(de)(de)(de)發熱。導(dao)體電(dian)(dian)(dian)阻(zu)不合格(ge)的(de)(de)(de)原因，主要(yao)進(jin)企業為了降低(di)成本(ben)，將(jiang)占(zhan)原材料(liao)(liao)成本(ben)80%的(de)(de)(de)銅(tong)材縮水(shui)，要(yao)么降低(di)導(dao)體的(de)(de)(de)截面(mian)積(ji)，要(yao)么使用含雜質過(guo)(guo)高的(de)(de)(de)再(zai)生銅(tong)，這(zhe)樣致使電(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)纜(lan)的(de)(de)(de)導(dao)體電(dian)(dian)(dian)阻(zu)嚴重超(chao)標(biao)，在使用過(guo)(guo)程中除(chu)易引(yin)發火災(zai)，還會加速包覆在電(dian)(dian)(dian)線(xian)外的(de)(de)(de)絕緣層的(de)(de)(de)老化(hua)。

在購買電線電纜(lan)的過程中，消費者應(ying)注意以下幾(ji)個(ge)事

第一、要觀察電線的外(wai)觀。合(he)格產(chan)品(pin)的絕緣（護套）層柔軟(ruan)、有(you)韌性和(he)伸縮性、表面(mian)層緊(jin)密、光滑、無粗糙感。如果包裹電線的塑料(liao)很容易被剝去，則存在(zai)塑料(liao)強度(du)不夠的問題。

第二、要看電(dian)線(xian)的截面。合格產品的銅芯(xin)(xin)或(huo)鋁芯(xin)(xin)表(biao)面應該具有金(jin)屬光澤，表(biao)面發(fa)黑的銅或(huo)表(biao)面發(fa)白的鋁說明已(yi)被氧(yang)化。

第三、在購買電線時應(ying)注意(yi)查看質(zhi)量合格證書。如果電線的質(zhi)量合格，那么(me)其(qi)電線質(zhi)量應(ying)該(gai)也受過檢驗，不會有太大的問題。
