不合格電(dian)線電(dian)纜的危(wei)害

電(dian)線電(dian)纜(lan)是用(yong)于傳(chuan)輸(shu)電(dian)力、傳(chuan)輸(shu)信息和實現電(dian)磁能(neng)量轉換的(de)一大類電(dian)工產品。在抽查過(guo)程中，發現了大量的(de)不合(he)格(ge)產品，這些劣(lie)質產品給電(dian)力系統正常運行(xing)埋(mai)下諸多隱患。

1、標(biao)志(zhi)不合格(ge)的(de)電線電纜。標(biao)志(zhi)是(shi)電線電纜使(shi)用識(shi)別產品(pin)基(ji)本信息的(de)主要途徑，根據(ju)標(biao)準規(gui)定(ding)(ding)標(biao)志(zhi)的(de)主要內容是(shi)：產品(pin)型(xing)號、規(gui)格(ge)、標(biao)準號、廠(chang)名、產地等在(zai)一(yi)定(ding)(ding)的(de)標(biao)示(shi)間距內，當(dang)標(biao)志(zhi)不合格(ge)時，會(hui)(hui)造(zao)成施工人員(yuan)識(shi)別錯誤，嚴重時會(hui)(hui)引發電氣事(shi)故(gu)。

2、結構(gou)尺(chi)寸(cun)(cun)不(bu)合格(ge)的(de)電(dian)(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)(dian)纜(lan)。結構(gou)尺(chi)寸(cun)(cun)的(de)主要(yao)問題是護(hu)套(tao)厚(hou)度(du)，絕(jue)(jue)緣(yuan)厚(hou)度(du)，當電(dian)(dian)(dian)(dian)纜(lan)的(de)護(hu)套(tao)和(he)絕(jue)(jue)緣(yuan)厚(hou)度(du)不(bu)達(da)標時(shi)，致(zhi)使(shi)電(dian)(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)(dian)纜(lan)耐(nai)電(dian)(dian)(dian)(dian)氣(qi)強度(du)會嚴重降低，導(dao)致(zhi)電(dian)(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)(dian)纜(lan)的(de)使(shi)用壽命縮短(duan)，嚴重時(shi)可(ke)導(dao)致(zhi)電(dian)(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)(dian)纜(lan)被擊(ji)穿，絕(jue)(jue)緣(yuan)（護(hu)套(tao)）層起不(bu)到(dao)正常保護(hu)作(zuo)用，從而發(fa)生電(dian)(dian)(dian)(dian)氣(qi)短(duan)路(lu)和(he)火災等(deng)現象。

3、護套(tao)式絕緣老(lao)化前(qian)的抗張(zhang)強度、伸(shen)長率合(he)(he)格的電(dian)線(xian)電(dian)纜。絕緣護套(tao)老(lao)化前(qian)的抗張(zhang)強度、伸(shen)長率不(bu)合(he)(he)格直接大大縮短電(dian)線(xian)電(dian)纜的工(gong)作用(yong)(yong)壽(shou)命，而且在施工(gong)或在長時間通(tong)電(dian)且溫度較高的環境中，極易(yi)出現(xian)絕緣體斷裂，致使(shi)(shi)帶電(dian)導體裸露，發生(sheng)能觸電(dian)式短路危險。其(qi)不(bu)合(he)(he)格的主要原因是使(shi)(shi)用(yong)(yong)了再生(sheng)料生(sheng)產，以降低產品(pin)成本，二是不(bu)具(ju)備生(sheng)產資格小型企業。

4、導(dao)(dao)體(ti)(ti)(ti)電(dian)阻不合格(ge)的(de)電(dian)線(xian)。導(dao)(dao)體(ti)(ti)(ti)電(dian)阻主(zhu)要(yao)是(shi)考(kao)核電(dian)線(xian)電(dian)纜的(de)導(dao)(dao)體(ti)(ti)(ti)材料以及截面是(shi)否(fou)符合的(de)重要(yao)指(zhi)標(biao)。當導(dao)(dao)體(ti)(ti)(ti)電(dian)阻超(chao)標(biao)時，就增大了電(dian)流在線(xian)路上通過時的(de)損耗，加劇了電(dian)線(xian)電(dian)纜的(de)發(fa)熱。導(dao)(dao)體(ti)(ti)(ti)電(dian)阻不合格(ge)的(de)原(yuan)因(yin)，主(zhu)要(yao)進企(qi)業為了降低成本，將占原(yuan)材料成本80%的(de)銅(tong)材縮水，要(yao)么(me)降低導(dao)(dao)體(ti)(ti)(ti)的(de)截面積，要(yao)么(me)使用含雜質過高的(de)再(zai)生(sheng)銅(tong)，這樣致使電(dian)線(xian)電(dian)纜的(de)導(dao)(dao)體(ti)(ti)(ti)電(dian)阻嚴重超(chao)標(biao)，在使用過程(cheng)中除易引發(fa)火(huo)災，還(huan)會加速包覆在電(dian)線(xian)外的(de)絕緣層的(de)老化(hua)。

在購買(mai)電(dian)線電(dian)纜的過程中，消費者應(ying)注(zhu)意(yi)以下幾個事

第一、要觀察電線的外觀。合格產品的絕(jue)緣（護套）層柔軟、有韌性(xing)和伸縮性(xing)、表面層緊密、光滑(hua)、無(wu)粗糙(cao)感。如果包(bao)裹(guo)電線的塑料很容易被剝去，則存在(zai)塑料強度不(bu)夠的問題。

第(di)二、要看電線的截面(mian)(mian)。合格產品的銅芯或(huo)鋁芯表(biao)面(mian)(mian)應(ying)該具有金屬光澤，表(biao)面(mian)(mian)發黑的銅或(huo)表(biao)面(mian)(mian)發白的鋁說明已(yi)被(bei)氧化。

第(di)三(san)、在購買電線(xian)時應(ying)注意(yi)查(cha)看質量(liang)合(he)格(ge)證書。如果電線(xian)的質量(liang)合(he)格(ge)，那么其電線(xian)質量(liang)應(ying)該也受過檢驗，不會有太大的問題。
