不(bu)合格(ge)電(dian)線電(dian)纜的(de)危害

電(dian)線電(dian)纜是用于傳輸電(dian)力、傳輸信息(xi)和實現電(dian)磁能量(liang)轉換(huan)的(de)一大類電(dian)工(gong)產品。在抽(chou)查過程(cheng)中，發(fa)現了大量(liang)的(de)不合格產品，這(zhe)些劣質產品給(gei)電(dian)力系(xi)統正常運行(xing)埋(mai)下諸多(duo)隱患(huan)。

1、標(biao)志不合格(ge)的(de)電(dian)(dian)(dian)線電(dian)(dian)(dian)纜。標(biao)志是(shi)電(dian)(dian)(dian)線電(dian)(dian)(dian)纜使用識別(bie)(bie)產品基本信(xin)息(xi)的(de)主要途徑，根據標(biao)準規定標(biao)志的(de)主要內容是(shi)：產品型號、規格(ge)、標(biao)準號、廠名(ming)、產地等在一定的(de)標(biao)示間距內，當(dang)標(biao)志不合格(ge)時，會(hui)造成施工人員識別(bie)(bie)錯誤，嚴重時會(hui)引發電(dian)(dian)(dian)氣(qi)事(shi)故。

2、結構(gou)尺(chi)寸(cun)(cun)不(bu)合格(ge)的電(dian)線(xian)電(dian)纜(lan)(lan)(lan)。結構(gou)尺(chi)寸(cun)(cun)的主要問題是護(hu)套厚度，絕(jue)緣(yuan)厚度，當電(dian)纜(lan)(lan)(lan)的護(hu)套和絕(jue)緣(yuan)厚度不(bu)達(da)標時，致使電(dian)線(xian)電(dian)纜(lan)(lan)(lan)耐電(dian)氣強度會嚴(yan)重(zhong)降低，導致電(dian)線(xian)電(dian)纜(lan)(lan)(lan)的使用(yong)壽命(ming)縮短，嚴(yan)重(zhong)時可導致電(dian)線(xian)電(dian)纜(lan)(lan)(lan)被擊(ji)穿，絕(jue)緣(yuan)（護(hu)套）層起不(bu)到正常保護(hu)作(zuo)用(yong)，從而發生電(dian)氣短路(lu)和火災等現象。

3、護套(tao)式(shi)絕(jue)緣老化前的(de)(de)抗(kang)張強(qiang)度、伸長(chang)率(lv)合(he)格(ge)的(de)(de)電(dian)(dian)線電(dian)(dian)纜(lan)。絕(jue)緣護套(tao)老化前的(de)(de)抗(kang)張強(qiang)度、伸長(chang)率(lv)不合(he)格(ge)直(zhi)接(jie)大(da)大(da)縮短電(dian)(dian)線電(dian)(dian)纜(lan)的(de)(de)工作(zuo)用(yong)壽命(ming)，而且(qie)在施工或在長(chang)時間通(tong)電(dian)(dian)且(qie)溫度較高的(de)(de)環境(jing)中，極易出現絕(jue)緣體斷裂(lie)，致使(shi)帶(dai)電(dian)(dian)導(dao)體裸露，發生(sheng)能觸(chu)電(dian)(dian)式(shi)短路(lu)危險。其不合(he)格(ge)的(de)(de)主要原因是(shi)使(shi)用(yong)了再生(sheng)料生(sheng)產(chan)，以(yi)降低產(chan)品成本，二是(shi)不具備生(sheng)產(chan)資格(ge)小型企業。

4、導(dao)(dao)體(ti)(ti)電(dian)阻不(bu)合格的(de)(de)(de)(de)(de)電(dian)線(xian)。導(dao)(dao)體(ti)(ti)電(dian)阻主要(yao)是考核電(dian)線(xian)電(dian)纜(lan)的(de)(de)(de)(de)(de)導(dao)(dao)體(ti)(ti)材料(liao)以及(ji)截面是否符(fu)合的(de)(de)(de)(de)(de)重(zhong)要(yao)指標(biao)。當導(dao)(dao)體(ti)(ti)電(dian)阻超標(biao)時(shi)，就增(zeng)大(da)了(le)電(dian)流(liu)在線(xian)路上(shang)通(tong)過時(shi)的(de)(de)(de)(de)(de)損耗，加劇了(le)電(dian)線(xian)電(dian)纜(lan)的(de)(de)(de)(de)(de)發熱。導(dao)(dao)體(ti)(ti)電(dian)阻不(bu)合格的(de)(de)(de)(de)(de)原因，主要(yao)進企業為(wei)了(le)降(jiang)低成本(ben)，將占原材料(liao)成本(ben)80%的(de)(de)(de)(de)(de)銅材縮水，要(yao)么降(jiang)低導(dao)(dao)體(ti)(ti)的(de)(de)(de)(de)(de)截面積(ji)，要(yao)么使(shi)(shi)用含雜(za)質過高的(de)(de)(de)(de)(de)再生(sheng)銅，這(zhe)樣致使(shi)(shi)電(dian)線(xian)電(dian)纜(lan)的(de)(de)(de)(de)(de)導(dao)(dao)體(ti)(ti)電(dian)阻嚴重(zhong)超標(biao)，在使(shi)(shi)用過程中除易引發火災，還(huan)會加速包覆(fu)在電(dian)線(xian)外(wai)的(de)(de)(de)(de)(de)絕(jue)緣(yuan)層的(de)(de)(de)(de)(de)老(lao)化。

在購買電線電纜的(de)過程(cheng)中(zhong)，消費者應(ying)注(zhu)意以下幾個事

第一(yi)、要(yao)觀(guan)察電線的(de)外(wai)觀(guan)。合(he)格產品(pin)的(de)絕緣（護套）層柔軟、有韌性(xing)和伸縮(suo)性(xing)、表面層緊密、光滑、無粗糙感。如果包裹電線的(de)塑料很容易被剝(bo)去，則存在塑料強度不(bu)夠的(de)問題。

第二、要(yao)看電線的截(jie)面(mian)。合格產(chan)品的銅(tong)芯(xin)或鋁芯(xin)表(biao)面(mian)應該具有(you)金屬光澤，表(biao)面(mian)發(fa)黑的銅(tong)或表(biao)面(mian)發(fa)白的鋁說明已被(bei)氧(yang)化。

第(di)三、在購買電線時應注意查(cha)看質量合(he)格證書。如果電線的(de)(de)質量合(he)格，那么其電線質量應該也受(shou)過檢驗，不會有太(tai)大的(de)(de)問題。
