不合格電(dian)(dian)線(xian)電(dian)(dian)纜的危害

電(dian)線電(dian)纜是用于傳(chuan)輸(shu)電(dian)力、傳(chuan)輸(shu)信(xin)息和實現(xian)電(dian)磁能量轉換(huan)的一(yi)大(da)類電(dian)工產品。在抽查過程中，發現(xian)了(le)大(da)量的不合格(ge)產品，這些劣質產品給電(dian)力系統正常運(yun)行埋下(xia)諸多隱患。

1、標(biao)(biao)志不(bu)合(he)格的(de)電(dian)線電(dian)纜。標(biao)(biao)志是電(dian)線電(dian)纜使用識別(bie)產品(pin)基(ji)本信息的(de)主(zhu)要途徑，根(gen)據(ju)標(biao)(biao)準規定標(biao)(biao)志的(de)主(zhu)要內(nei)容(rong)是：產品(pin)型號、規格、標(biao)(biao)準號、廠名、產地等在一定的(de)標(biao)(biao)示間距內(nei)，當標(biao)(biao)志不(bu)合(he)格時，會造成施工人員識別(bie)錯(cuo)誤(wu)，嚴重時會引發電(dian)氣事故。

2、結(jie)構(gou)(gou)尺寸(cun)不合(he)格(ge)的(de)電(dian)(dian)線(xian)電(dian)(dian)纜。結(jie)構(gou)(gou)尺寸(cun)的(de)主要(yao)問(wen)題是(shi)護(hu)套厚度，絕緣厚度，當電(dian)(dian)纜的(de)護(hu)套和絕緣厚度不達標時，致使電(dian)(dian)線(xian)電(dian)(dian)纜耐電(dian)(dian)氣強度會嚴重(zhong)降低，導(dao)致電(dian)(dian)線(xian)電(dian)(dian)纜的(de)使用壽命縮短(duan)，嚴重(zhong)時可(ke)導(dao)致電(dian)(dian)線(xian)電(dian)(dian)纜被擊穿，絕緣（護(hu)套）層起不到正(zheng)常(chang)保(bao)護(hu)作用，從而(er)發生(sheng)電(dian)(dian)氣短(duan)路和火(huo)災等現象。

3、護(hu)套式(shi)絕(jue)緣老(lao)化(hua)(hua)前的抗張(zhang)強度(du)、伸(shen)長率(lv)合(he)格的電(dian)線電(dian)纜。絕(jue)緣護(hu)套老(lao)化(hua)(hua)前的抗張(zhang)強度(du)、伸(shen)長率(lv)不(bu)合(he)格直(zhi)接(jie)大大縮短電(dian)線電(dian)纜的工(gong)作(zuo)用壽(shou)命(ming)，而且(qie)在施工(gong)或在長時間通(tong)電(dian)且(qie)溫度(du)較高(gao)的環(huan)境中，極易(yi)出(chu)現絕(jue)緣體斷(duan)裂，致使(shi)帶(dai)電(dian)導(dao)體裸(luo)露，發生(sheng)能觸電(dian)式(shi)短路危險。其不(bu)合(he)格的主要原因是(shi)使(shi)用了(le)再生(sheng)料生(sheng)產(chan)，以降低產(chan)品(pin)成本，二是(shi)不(bu)具備生(sheng)產(chan)資格小型企(qi)業。

4、導體(ti)電(dian)(dian)(dian)(dian)阻不合格的(de)(de)電(dian)(dian)(dian)(dian)線。導體(ti)電(dian)(dian)(dian)(dian)阻主要是考核電(dian)(dian)(dian)(dian)線電(dian)(dian)(dian)(dian)纜(lan)(lan)的(de)(de)導體(ti)材料以及截面(mian)是否符合的(de)(de)重(zhong)要指標。當導體(ti)電(dian)(dian)(dian)(dian)阻超標時，就(jiu)增大了電(dian)(dian)(dian)(dian)流在(zai)線路上通過時的(de)(de)損耗，加劇了電(dian)(dian)(dian)(dian)線電(dian)(dian)(dian)(dian)纜(lan)(lan)的(de)(de)發(fa)熱。導體(ti)電(dian)(dian)(dian)(dian)阻不合格的(de)(de)原因，主要進企業為了降低成(cheng)本，將(jiang)占原材料成(cheng)本80%的(de)(de)銅材縮水，要么降低導體(ti)的(de)(de)截面(mian)積，要么使用(yong)含雜質過高的(de)(de)再生銅，這樣(yang)致使電(dian)(dian)(dian)(dian)線電(dian)(dian)(dian)(dian)纜(lan)(lan)的(de)(de)導體(ti)電(dian)(dian)(dian)(dian)阻嚴(yan)重(zhong)超標，在(zai)使用(yong)過程中(zhong)除易引(yin)發(fa)火災，還(huan)會加速包覆在(zai)電(dian)(dian)(dian)(dian)線外的(de)(de)絕(jue)緣層(ceng)的(de)(de)老化。

在(zai)購買電線電纜的(de)過程(cheng)中，消費(fei)者應注意以(yi)下幾(ji)個事

第(di)一、要觀察電線的外觀。合格產品的絕緣（護(hu)套）層柔軟、有韌性和伸縮(suo)性、表(biao)面(mian)層緊密、光滑、無粗糙感。如果包(bao)裹電線的塑料(liao)很容易被(bei)剝去，則存在(zai)塑料(liao)強度不夠的問題。

第二、要(yao)看(kan)電線的(de)截面。合格(ge)產(chan)品(pin)的(de)銅芯(xin)或(huo)鋁(lv)芯(xin)表(biao)面應該具有金屬(shu)光澤，表(biao)面發黑的(de)銅或(huo)表(biao)面發白的(de)鋁(lv)說明已被氧(yang)化。

第三(san)、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(me)其電線(xian)質(zhi)量應該也受過檢驗(yan)，不會有太大(da)的問題(ti)。
