不合格電線(xian)電纜(lan)的危害

電(dian)線(xian)電(dian)纜(lan)是(shi)用于傳輸電(dian)力(li)、傳輸信(xin)息和實現電(dian)磁能量轉換的一大類電(dian)工產品(pin)。在抽查(cha)過程中，發現了大量的不合(he)格產品(pin)，這些劣(lie)質產品(pin)給電(dian)力(li)系統正常運行埋下諸多(duo)隱患。

1、標(biao)(biao)志(zhi)不合格的(de)電(dian)線電(dian)纜。標(biao)(biao)志(zhi)是(shi)電(dian)線電(dian)纜使用識別(bie)產(chan)品基本信息的(de)主要(yao)途徑(jing)，根(gen)據(ju)標(biao)(biao)準規定標(biao)(biao)志(zhi)的(de)主要(yao)內容(rong)是(shi)：產(chan)品型號、規格、標(biao)(biao)準號、廠名、產(chan)地等在一定的(de)標(biao)(biao)示間距內，當標(biao)(biao)志(zhi)不合格時(shi)，會(hui)造成施工人員識別(bie)錯誤，嚴(yan)重時(shi)會(hui)引發電(dian)氣事故。

2、結(jie)(jie)構尺寸不合格(ge)的電線電纜(lan)(lan)。結(jie)(jie)構尺寸的主要問(wen)題是護(hu)套厚(hou)度(du)(du)，絕緣(yuan)厚(hou)度(du)(du)，當電纜(lan)(lan)的護(hu)套和絕緣(yuan)厚(hou)度(du)(du)不達標時，致使電線電纜(lan)(lan)耐電氣強(qiang)度(du)(du)會(hui)嚴重降低，導致電線電纜(lan)(lan)的使用壽命縮(suo)短(duan)(duan)，嚴重時可導致電線電纜(lan)(lan)被擊(ji)穿，絕緣(yuan)（護(hu)套）層起不到正常保護(hu)作(zuo)用，從而(er)發生(sheng)電氣短(duan)(duan)路和火災等現象。

3、護(hu)(hu)套式絕(jue)(jue)緣(yuan)老(lao)化前(qian)的(de)抗(kang)(kang)張(zhang)強(qiang)度(du)、伸長率(lv)合(he)格的(de)電(dian)線(xian)電(dian)纜。絕(jue)(jue)緣(yuan)護(hu)(hu)套老(lao)化前(qian)的(de)抗(kang)(kang)張(zhang)強(qiang)度(du)、伸長率(lv)不(bu)合(he)格直接大大縮(suo)短(duan)電(dian)線(xian)電(dian)纜的(de)工作用壽命，而且(qie)在施工或在長時間通電(dian)且(qie)溫度(du)較高的(de)環境中，極(ji)易出現絕(jue)(jue)緣(yuan)體斷裂，致使帶電(dian)導體裸露，發生(sheng)能觸電(dian)式短(duan)路危險。其不(bu)合(he)格的(de)主要原因是使用了再生(sheng)料(liao)生(sheng)產，以(yi)降低產品成(cheng)本，二是不(bu)具備(bei)生(sheng)產資格小型企業(ye)。

4、導(dao)體(ti)(ti)(ti)電(dian)(dian)(dian)(dian)(dian)阻(zu)(zu)不合格的(de)電(dian)(dian)(dian)(dian)(dian)線(xian)。導(dao)體(ti)(ti)(ti)電(dian)(dian)(dian)(dian)(dian)阻(zu)(zu)主要是(shi)(shi)考核(he)電(dian)(dian)(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)(dian)(dian)纜的(de)導(dao)體(ti)(ti)(ti)材(cai)(cai)(cai)料(liao)(liao)以及(ji)截(jie)面(mian)是(shi)(shi)否符合的(de)重要指標(biao)。當導(dao)體(ti)(ti)(ti)電(dian)(dian)(dian)(dian)(dian)阻(zu)(zu)超標(biao)時，就增(zeng)大了(le)電(dian)(dian)(dian)(dian)(dian)流在(zai)(zai)線(xian)路上通過時的(de)損耗，加(jia)劇了(le)電(dian)(dian)(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)(dian)(dian)纜的(de)發(fa)熱。導(dao)體(ti)(ti)(ti)電(dian)(dian)(dian)(dian)(dian)阻(zu)(zu)不合格的(de)原(yuan)因，主要進企業(ye)為了(le)降低(di)成本，將(jiang)占原(yuan)材(cai)(cai)(cai)料(liao)(liao)成本80%的(de)銅(tong)材(cai)(cai)(cai)縮水，要么降低(di)導(dao)體(ti)(ti)(ti)的(de)截(jie)面(mian)積，要么使(shi)(shi)用含雜質過高的(de)再生銅(tong)，這樣致使(shi)(shi)電(dian)(dian)(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)(dian)(dian)纜的(de)導(dao)體(ti)(ti)(ti)電(dian)(dian)(dian)(dian)(dian)阻(zu)(zu)嚴重超標(biao)，在(zai)(zai)使(shi)(shi)用過程中除易引(yin)發(fa)火災，還會(hui)加(jia)速包覆(fu)在(zai)(zai)電(dian)(dian)(dian)(dian)(dian)線(xian)外(wai)的(de)絕緣層的(de)老化(hua)。

在購買電線(xian)電纜(lan)的過程(cheng)中，消費者應注(zhu)意以下幾(ji)個事

第一、要觀察(cha)電線(xian)的外(wai)觀。合(he)格產品的絕緣（護套）層柔軟(ruan)、有韌(ren)性和(he)伸(shen)縮(suo)性、表面層緊密(mi)、光滑、無(wu)粗糙感。如果包(bao)裹電線(xian)的塑料很容易(yi)被(bei)剝去，則(ze)存(cun)在塑料強度不夠的問題。

第(di)二、要看電線的(de)截面(mian)。合格(ge)產品(pin)的(de)銅(tong)芯或鋁芯表(biao)面(mian)應(ying)該具有金屬光澤，表(biao)面(mian)發黑的(de)銅(tong)或表(biao)面(mian)發白的(de)鋁說明已被(bei)氧化。

第三、在購(gou)買電線(xian)(xian)時應(ying)注意查看質量(liang)合(he)格(ge)證書。如果電線(xian)(xian)的(de)(de)質量(liang)合(he)格(ge)，那么(me)其電線(xian)(xian)質量(liang)應(ying)該也受(shou)過檢驗，不會有太(tai)大的(de)(de)問題。
