不合格電(dian)(dian)線電(dian)(dian)纜的危害

電(dian)線電(dian)纜是用于(yu)傳輸電(dian)力(li)、傳輸信息和實現電(dian)磁能量轉換的一大類(lei)電(dian)工(gong)產品(pin)。在抽查(cha)過(guo)程中，發現了(le)大量的不合格產品(pin)，這些劣質(zhi)產品(pin)給(gei)電(dian)力(li)系統(tong)正常運行(xing)埋下(xia)諸多隱患。

1、標(biao)志(zhi)不(bu)合(he)格(ge)的(de)電(dian)線(xian)電(dian)纜。標(biao)志(zhi)是電(dian)線(xian)電(dian)纜使用識別產(chan)(chan)品基(ji)本(ben)信息的(de)主要途徑，根(gen)據標(biao)準規定標(biao)志(zhi)的(de)主要內(nei)容是：產(chan)(chan)品型號(hao)、規格(ge)、標(biao)準號(hao)、廠名、產(chan)(chan)地等在一定的(de)標(biao)示間距內(nei)，當標(biao)志(zhi)不(bu)合(he)格(ge)時，會(hui)造(zao)成施工人員(yuan)識別錯誤，嚴重時會(hui)引發電(dian)氣事故。

2、結構(gou)尺(chi)寸不合格的(de)電(dian)線(xian)(xian)電(dian)纜(lan)(lan)。結構(gou)尺(chi)寸的(de)主(zhu)要(yao)問題是護(hu)套(tao)厚度(du)(du)，絕(jue)(jue)(jue)緣厚度(du)(du)，當電(dian)纜(lan)(lan)的(de)護(hu)套(tao)和絕(jue)(jue)(jue)緣厚度(du)(du)不達標時，致使電(dian)線(xian)(xian)電(dian)纜(lan)(lan)耐(nai)電(dian)氣強度(du)(du)會嚴重降低，導(dao)(dao)致電(dian)線(xian)(xian)電(dian)纜(lan)(lan)的(de)使用壽命(ming)縮短，嚴重時可導(dao)(dao)致電(dian)線(xian)(xian)電(dian)纜(lan)(lan)被擊穿，絕(jue)(jue)(jue)緣（護(hu)套(tao)）層起不到(dao)正常保護(hu)作(zuo)用，從而發(fa)生電(dian)氣短路(lu)和火災等現象。

3、護套(tao)式絕(jue)緣老化前(qian)的(de)抗(kang)張(zhang)(zhang)強度、伸(shen)長率合(he)格(ge)的(de)電(dian)(dian)(dian)線(xian)(xian)電(dian)(dian)(dian)纜。絕(jue)緣護套(tao)老化前(qian)的(de)抗(kang)張(zhang)(zhang)強度、伸(shen)長率不合(he)格(ge)直接大(da)大(da)縮(suo)短電(dian)(dian)(dian)線(xian)(xian)電(dian)(dian)(dian)纜的(de)工(gong)作(zuo)用(yong)壽命，而且在施工(gong)或在長時間通電(dian)(dian)(dian)且溫度較高的(de)環境中，極易出現絕(jue)緣體斷裂，致使(shi)帶電(dian)(dian)(dian)導體裸露(lu)，發生能觸電(dian)(dian)(dian)式短路危(wei)險。其不合(he)格(ge)的(de)主要原(yuan)因是使(shi)用(yong)了再生料生產，以降低產品成(cheng)本，二是不具備(bei)生產資格(ge)小型企業。

4、導體(ti)(ti)電(dian)(dian)(dian)(dian)阻(zu)不(bu)合格的(de)(de)(de)電(dian)(dian)(dian)(dian)線。導體(ti)(ti)電(dian)(dian)(dian)(dian)阻(zu)主(zhu)要(yao)(yao)是(shi)考核(he)電(dian)(dian)(dian)(dian)線電(dian)(dian)(dian)(dian)纜的(de)(de)(de)導體(ti)(ti)材(cai)料(liao)以及截面是(shi)否(fou)符(fu)合的(de)(de)(de)重(zhong)要(yao)(yao)指標(biao)。當導體(ti)(ti)電(dian)(dian)(dian)(dian)阻(zu)超(chao)標(biao)時，就增大了(le)電(dian)(dian)(dian)(dian)流在(zai)線路(lu)上通過(guo)時的(de)(de)(de)損耗(hao)，加(jia)劇了(le)電(dian)(dian)(dian)(dian)線電(dian)(dian)(dian)(dian)纜的(de)(de)(de)發熱。導體(ti)(ti)電(dian)(dian)(dian)(dian)阻(zu)不(bu)合格的(de)(de)(de)原(yuan)因，主(zhu)要(yao)(yao)進企業為了(le)降低成(cheng)(cheng)本，將占原(yuan)材(cai)料(liao)成(cheng)(cheng)本80%的(de)(de)(de)銅材(cai)縮(suo)水，要(yao)(yao)么降低導體(ti)(ti)的(de)(de)(de)截面積，要(yao)(yao)么使用含雜質(zhi)過(guo)高(gao)的(de)(de)(de)再生(sheng)銅，這(zhe)樣致使電(dian)(dian)(dian)(dian)線電(dian)(dian)(dian)(dian)纜的(de)(de)(de)導體(ti)(ti)電(dian)(dian)(dian)(dian)阻(zu)嚴(yan)重(zhong)超(chao)標(biao)，在(zai)使用過(guo)程中除易引(yin)發火災，還會(hui)加(jia)速包覆(fu)在(zai)電(dian)(dian)(dian)(dian)線外的(de)(de)(de)絕緣層的(de)(de)(de)老化。

在(zai)購買電線電纜的(de)過程中，消費者應(ying)注意以下幾個事

第(di)一、要觀(guan)察電線的(de)(de)外觀(guan)。合格產品的(de)(de)絕緣（護套）層柔軟、有韌性和(he)伸縮性、表面(mian)層緊(jin)密、光滑、無粗(cu)糙感。如(ru)果(guo)包裹電線的(de)(de)塑料(liao)很容易被剝去，則(ze)存在塑料(liao)強度不(bu)夠的(de)(de)問題。

第(di)二(er)、要看(kan)電線的截面。合格產品的銅(tong)芯或鋁(lv)芯表(biao)(biao)面應(ying)該具有(you)金屬光(guang)澤，表(biao)(biao)面發(fa)黑的銅(tong)或表(biao)(biao)面發(fa)白(bai)的鋁(lv)說明已(yi)被(bei)氧化。

第三、在購買電線時應(ying)注(zhu)意查(cha)看質量(liang)合格證(zheng)書(shu)。如果電線的(de)質量(liang)合格，那么其電線質量(liang)應(ying)該也(ye)受過檢驗，不(bu)會有太(tai)大的(de)問(wen)題(ti)。
