不合(he)格電(dian)線電(dian)纜的危(wei)害

電(dian)(dian)線電(dian)(dian)纜(lan)是用于傳輸(shu)電(dian)(dian)力(li)、傳輸(shu)信息(xi)和實現電(dian)(dian)磁能量(liang)轉換的一大類電(dian)(dian)工產品(pin)。在抽查過程中(zhong)，發現了(le)大量(liang)的不合格(ge)產品(pin)，這些劣(lie)質產品(pin)給電(dian)(dian)力(li)系(xi)統正常(chang)運行埋下諸多隱患。

1、標志(zhi)(zhi)(zhi)不合(he)格的電(dian)(dian)(dian)線電(dian)(dian)(dian)纜。標志(zhi)(zhi)(zhi)是(shi)電(dian)(dian)(dian)線電(dian)(dian)(dian)纜使用識別產(chan)品基本(ben)信息(xi)的主要途徑，根據標準(zhun)規(gui)(gui)定(ding)標志(zhi)(zhi)(zhi)的主要內容是(shi)：產(chan)品型號(hao)、規(gui)(gui)格、標準(zhun)號(hao)、廠名(ming)、產(chan)地等在一(yi)定(ding)的標示間距內，當標志(zhi)(zhi)(zhi)不合(he)格時，會造(zao)成施(shi)工(gong)人員(yuan)識別錯(cuo)誤，嚴重時會引發電(dian)(dian)(dian)氣(qi)事故。

2、結(jie)構(gou)尺寸不合格的(de)(de)(de)電線(xian)電纜。結(jie)構(gou)尺寸的(de)(de)(de)主要問題是護套(tao)厚度，絕緣(yuan)厚度，當電纜的(de)(de)(de)護套(tao)和絕緣(yuan)厚度不達(da)標(biao)時(shi)，致(zhi)使電線(xian)電纜耐電氣強度會嚴重(zhong)降低，導(dao)致(zhi)電線(xian)電纜的(de)(de)(de)使用壽(shou)命縮短，嚴重(zhong)時(shi)可(ke)導(dao)致(zhi)電線(xian)電纜被擊穿，絕緣(yuan)（護套(tao)）層起不到正(zheng)常保護作用，從而(er)發(fa)生電氣短路和火災等現象。

3、護套(tao)(tao)式絕緣(yuan)老(lao)化前(qian)的(de)抗(kang)張強(qiang)度(du)、伸長(chang)率(lv)合格(ge)的(de)電(dian)線電(dian)纜。絕緣(yuan)護套(tao)(tao)老(lao)化前(qian)的(de)抗(kang)張強(qiang)度(du)、伸長(chang)率(lv)不(bu)(bu)合格(ge)直(zhi)接大大縮(suo)短(duan)電(dian)線電(dian)纜的(de)工作用壽命(ming)，而且在施工或在長(chang)時間通電(dian)且溫度(du)較高的(de)環(huan)境(jing)中，極易出(chu)現絕緣(yuan)體(ti)斷裂，致使帶電(dian)導體(ti)裸(luo)露，發(fa)生(sheng)(sheng)能觸電(dian)式短(duan)路危險。其(qi)不(bu)(bu)合格(ge)的(de)主要原因(yin)是(shi)使用了再生(sheng)(sheng)料生(sheng)(sheng)產(chan)，以降低(di)產(chan)品成本，二(er)是(shi)不(bu)(bu)具備生(sheng)(sheng)產(chan)資格(ge)小型企業。

4、導(dao)體電(dian)阻不合格的(de)(de)電(dian)線(xian)(xian)。導(dao)體電(dian)阻主(zhu)要(yao)是考(kao)核電(dian)線(xian)(xian)電(dian)纜的(de)(de)導(dao)體材料(liao)以及截面是否(fou)符合的(de)(de)重要(yao)指標(biao)。當導(dao)體電(dian)阻超標(biao)時(shi)，就增大了電(dian)流在(zai)線(xian)(xian)路上通過(guo)時(shi)的(de)(de)損耗，加(jia)劇了電(dian)線(xian)(xian)電(dian)纜的(de)(de)發熱。導(dao)體電(dian)阻不合格的(de)(de)原(yuan)因，主(zhu)要(yao)進企業為了降低(di)成本(ben)(ben)，將(jiang)占原(yuan)材料(liao)成本(ben)(ben)80%的(de)(de)銅(tong)材縮水，要(yao)么(me)降低(di)導(dao)體的(de)(de)截面積，要(yao)么(me)使(shi)用含雜質過(guo)高的(de)(de)再生銅(tong)，這樣致使(shi)電(dian)線(xian)(xian)電(dian)纜的(de)(de)導(dao)體電(dian)阻嚴(yan)重超標(biao)，在(zai)使(shi)用過(guo)程中除易引發火(huo)災，還(huan)會加(jia)速(su)包覆在(zai)電(dian)線(xian)(xian)外的(de)(de)絕緣(yuan)層的(de)(de)老化(hua)。

在(zai)購(gou)買電(dian)線電(dian)纜的過程中，消費者(zhe)應注(zhu)意以下幾個事

第一、要(yao)觀(guan)察電(dian)線的(de)(de)外觀(guan)。合格產品的(de)(de)絕緣（護套）層柔軟、有韌性(xing)和伸(shen)縮性(xing)、表面(mian)層緊密、光滑、無粗糙感(gan)。如果包(bao)裹電(dian)線的(de)(de)塑(su)料(liao)(liao)很容易被剝(bo)去(qu)，則(ze)存(cun)在塑(su)料(liao)(liao)強度不(bu)夠的(de)(de)問(wen)題。

第二、要看電線的截面。合格(ge)產品的銅芯(xin)或鋁芯(xin)表(biao)面應該具有(you)金(jin)屬光澤(ze)，表(biao)面發(fa)黑的銅或表(biao)面發(fa)白的鋁說明已被(bei)氧化。

第三、在(zai)購買電(dian)線時應(ying)注意查(cha)看(kan)質(zhi)量合格證書。如(ru)果電(dian)線的質(zhi)量合格，那么其(qi)電(dian)線質(zhi)量應(ying)該也受過檢(jian)驗，不會有(you)太大的問題。
