不合格(ge)電線(xian)電纜的危(wei)害

電(dian)線(xian)電(dian)纜是用(yong)于傳輸電(dian)力、傳輸信息和(he)實(shi)現電(dian)磁能量(liang)轉(zhuan)換的一大(da)類(lei)電(dian)工產品。在抽查(cha)過程中，發現了大(da)量(liang)的不合格產品，這些劣質產品給電(dian)力系統正常運行埋下(xia)諸多隱患。

1、標(biao)(biao)(biao)志(zhi)不(bu)合格(ge)的(de)電(dian)(dian)線電(dian)(dian)纜。標(biao)(biao)(biao)志(zhi)是電(dian)(dian)線電(dian)(dian)纜使(shi)用識別(bie)產品基本信息的(de)主要途徑，根(gen)據(ju)標(biao)(biao)(biao)準規(gui)定標(biao)(biao)(biao)志(zhi)的(de)主要內(nei)容是：產品型號(hao)、規(gui)格(ge)、標(biao)(biao)(biao)準號(hao)、廠名、產地等在一定的(de)標(biao)(biao)(biao)示間距(ju)內(nei)，當標(biao)(biao)(biao)志(zhi)不(bu)合格(ge)時，會造成(cheng)施工(gong)人(ren)員(yuan)識別(bie)錯誤(wu)，嚴重時會引發電(dian)(dian)氣事故。

2、結(jie)構(gou)尺寸不(bu)合格的(de)電(dian)(dian)線(xian)電(dian)(dian)纜(lan)。結(jie)構(gou)尺寸的(de)主要問題是護套厚度(du)，絕(jue)緣(yuan)厚度(du)，當電(dian)(dian)纜(lan)的(de)護套和絕(jue)緣(yuan)厚度(du)不(bu)達(da)標時，致(zhi)使電(dian)(dian)線(xian)電(dian)(dian)纜(lan)耐電(dian)(dian)氣(qi)強度(du)會嚴重降低(di)，導(dao)致(zhi)電(dian)(dian)線(xian)電(dian)(dian)纜(lan)的(de)使用壽(shou)命縮短(duan)，嚴重時可導(dao)致(zhi)電(dian)(dian)線(xian)電(dian)(dian)纜(lan)被擊(ji)穿，絕(jue)緣(yuan)（護套）層(ceng)起不(bu)到正(zheng)常保(bao)護作用，從而發生(sheng)電(dian)(dian)氣(qi)短(duan)路和火(huo)災(zai)等現象。

3、護(hu)套(tao)式絕緣老化前的(de)抗(kang)張強(qiang)度、伸長率(lv)合(he)格(ge)的(de)電(dian)線電(dian)纜。絕緣護(hu)套(tao)老化前的(de)抗(kang)張強(qiang)度、伸長率(lv)不合(he)格(ge)直接大大縮短電(dian)線電(dian)纜的(de)工(gong)作用(yong)壽命，而且(qie)在施(shi)工(gong)或在長時間通(tong)電(dian)且(qie)溫度較高的(de)環境中，極易出現絕緣體(ti)斷(duan)裂，致(zhi)使(shi)帶電(dian)導體(ti)裸露，發生能觸(chu)電(dian)式短路危險(xian)。其不合(he)格(ge)的(de)主要原因是使(shi)用(yong)了再生料生產(chan)，以降低產(chan)品成本，二是不具備(bei)生產(chan)資格(ge)小(xiao)型企業。

4、導(dao)體電(dian)(dian)(dian)阻不合(he)格的(de)(de)(de)(de)電(dian)(dian)(dian)線(xian)(xian)。導(dao)體電(dian)(dian)(dian)阻主要(yao)(yao)(yao)是考核電(dian)(dian)(dian)線(xian)(xian)電(dian)(dian)(dian)纜(lan)的(de)(de)(de)(de)導(dao)體材料(liao)以及(ji)截面是否符合(he)的(de)(de)(de)(de)重要(yao)(yao)(yao)指標。當(dang)導(dao)體電(dian)(dian)(dian)阻超標時，就增大了電(dian)(dian)(dian)流(liu)在(zai)線(xian)(xian)路(lu)上通過(guo)時的(de)(de)(de)(de)損耗，加(jia)劇了電(dian)(dian)(dian)線(xian)(xian)電(dian)(dian)(dian)纜(lan)的(de)(de)(de)(de)發熱。導(dao)體電(dian)(dian)(dian)阻不合(he)格的(de)(de)(de)(de)原因，主要(yao)(yao)(yao)進企業(ye)為了降低(di)成本(ben)，將(jiang)占原材料(liao)成本(ben)80%的(de)(de)(de)(de)銅材縮水(shui)，要(yao)(yao)(yao)么(me)降低(di)導(dao)體的(de)(de)(de)(de)截面積，要(yao)(yao)(yao)么(me)使用含雜質過(guo)高的(de)(de)(de)(de)再生銅，這樣致(zhi)使電(dian)(dian)(dian)線(xian)(xian)電(dian)(dian)(dian)纜(lan)的(de)(de)(de)(de)導(dao)體電(dian)(dian)(dian)阻嚴重超標，在(zai)使用過(guo)程中(zhong)除易引發火災，還會加(jia)速包覆在(zai)電(dian)(dian)(dian)線(xian)(xian)外的(de)(de)(de)(de)絕緣層的(de)(de)(de)(de)老化(hua)。

在購買電(dian)線電(dian)纜的過(guo)程(cheng)中，消費者應注意以下(xia)幾個事(shi)

第一(yi)、要觀(guan)察電線的(de)外(wai)觀(guan)。合格產(chan)品的(de)絕緣（護套）層柔(rou)軟(ruan)、有韌性和(he)伸縮性、表面層緊密、光滑、無粗糙(cao)感。如(ru)果包裹電線的(de)塑(su)料(liao)很容易被剝(bo)去，則存在(zai)塑(su)料(liao)強(qiang)度不夠的(de)問(wen)題。

第(di)二、要看(kan)電線的截(jie)面(mian)。合格產品(pin)的銅芯或(huo)鋁芯表(biao)面(mian)應該具有金屬光(guang)澤(ze)，表(biao)面(mian)發(fa)黑的銅或(huo)表(biao)面(mian)發(fa)白(bai)的鋁說明已被(bei)氧化。

第三、在購買電線(xian)時應注意查看質(zhi)量合格證書。如果電線(xian)的質(zhi)量合格，那么其電線(xian)質(zhi)量應該(gai)也受(shou)過檢驗(yan)，不會有(you)太大的問題。
