不(bu)合格電線電纜的危害

電(dian)(dian)線電(dian)(dian)纜是用于傳(chuan)輸電(dian)(dian)力、傳(chuan)輸信息和實現電(dian)(dian)磁(ci)能量轉換(huan)的(de)一大類電(dian)(dian)工(gong)產(chan)品。在抽(chou)查過(guo)程中，發現了大量的(de)不合格(ge)產(chan)品，這些劣質產(chan)品給(gei)電(dian)(dian)力系統正常運行埋下諸多隱(yin)患(huan)。

1、標(biao)志不合格(ge)(ge)的電(dian)線(xian)電(dian)纜。標(biao)志是電(dian)線(xian)電(dian)纜使用識(shi)別(bie)產(chan)(chan)品基本(ben)信息的主要途(tu)徑，根(gen)據(ju)標(biao)準規(gui)定(ding)標(biao)志的主要內(nei)容是：產(chan)(chan)品型(xing)號(hao)、規(gui)格(ge)(ge)、標(biao)準號(hao)、廠名、產(chan)(chan)地(di)等在一定(ding)的標(biao)示間距(ju)內(nei)，當標(biao)志不合格(ge)(ge)時，會(hui)造成施工(gong)人(ren)員識(shi)別(bie)錯誤(wu)，嚴重時會(hui)引發電(dian)氣事故。

2、結構尺(chi)寸不(bu)合格的電(dian)線(xian)電(dian)纜。結構尺(chi)寸的主要問(wen)題是護套厚度(du)(du)，絕(jue)緣厚度(du)(du)，當電(dian)纜的護套和(he)絕(jue)緣厚度(du)(du)不(bu)達(da)標(biao)時，致使電(dian)線(xian)電(dian)纜耐電(dian)氣(qi)強度(du)(du)會嚴重降低，導致電(dian)線(xian)電(dian)纜的使用壽(shou)命縮短(duan)，嚴重時可導致電(dian)線(xian)電(dian)纜被擊穿(chuan)，絕(jue)緣（護套）層起不(bu)到正常保護作用，從而(er)發生電(dian)氣(qi)短(duan)路和(he)火災等現象。

3、護套式(shi)絕緣老化(hua)前的(de)抗張(zhang)強度(du)、伸(shen)長率(lv)合格的(de)電(dian)(dian)線電(dian)(dian)纜。絕緣護套老化(hua)前的(de)抗張(zhang)強度(du)、伸(shen)長率(lv)不(bu)合格直接(jie)大(da)大(da)縮短(duan)(duan)電(dian)(dian)線電(dian)(dian)纜的(de)工(gong)作用壽命(ming)，而(er)且在(zai)(zai)施工(gong)或在(zai)(zai)長時間(jian)通(tong)電(dian)(dian)且溫度(du)較高的(de)環(huan)境中，極易(yi)出現(xian)絕緣體斷裂(lie)，致使帶電(dian)(dian)導體裸露(lu)，發(fa)生能觸(chu)電(dian)(dian)式(shi)短(duan)(duan)路危險。其不(bu)合格的(de)主要原(yuan)因(yin)是使用了再生料生產，以降低(di)產品(pin)成本，二是不(bu)具備生產資格小型企業(ye)。

4、導(dao)(dao)體(ti)(ti)電(dian)(dian)(dian)(dian)(dian)(dian)阻不合(he)格(ge)的(de)電(dian)(dian)(dian)(dian)(dian)(dian)線(xian)(xian)。導(dao)(dao)體(ti)(ti)電(dian)(dian)(dian)(dian)(dian)(dian)阻主要(yao)是(shi)考(kao)核電(dian)(dian)(dian)(dian)(dian)(dian)線(xian)(xian)電(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)的(de)導(dao)(dao)體(ti)(ti)材(cai)(cai)料(liao)(liao)以及截面是(shi)否符合(he)的(de)重要(yao)指(zhi)標。當導(dao)(dao)體(ti)(ti)電(dian)(dian)(dian)(dian)(dian)(dian)阻超標時，就增大(da)了電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)在線(xian)(xian)路(lu)上(shang)通過時的(de)損(sun)耗，加(jia)劇了電(dian)(dian)(dian)(dian)(dian)(dian)線(xian)(xian)電(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)的(de)發熱。導(dao)(dao)體(ti)(ti)電(dian)(dian)(dian)(dian)(dian)(dian)阻不合(he)格(ge)的(de)原因，主要(yao)進企業為了降低成本(ben)，將(jiang)占原材(cai)(cai)料(liao)(liao)成本(ben)80%的(de)銅(tong)材(cai)(cai)縮水，要(yao)么降低導(dao)(dao)體(ti)(ti)的(de)截面積，要(yao)么使(shi)用含雜(za)質過高的(de)再生(sheng)銅(tong)，這樣致(zhi)使(shi)電(dian)(dian)(dian)(dian)(dian)(dian)線(xian)(xian)電(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)的(de)導(dao)(dao)體(ti)(ti)電(dian)(dian)(dian)(dian)(dian)(dian)阻嚴重超標，在使(shi)用過程中(zhong)除易引發火災，還會加(jia)速包(bao)覆(fu)在電(dian)(dian)(dian)(dian)(dian)(dian)線(xian)(xian)外的(de)絕緣層的(de)老化。

在購(gou)買電(dian)線電(dian)纜的(de)過程(cheng)中，消(xiao)費者應注意以下幾個事

第一、要觀(guan)察電線的(de)外(wai)觀(guan)。合格產(chan)品的(de)絕緣(yuan)（護套(tao)）層柔軟、有韌(ren)性和伸(shen)縮性、表面層緊密、光滑、無粗(cu)糙感。如果包裹(guo)電線的(de)塑料很容易被剝(bo)去(qu)，則存在塑料強度不夠的(de)問題。

第二、要看電線的截面(mian)。合格產品的銅芯或(huo)鋁芯表面(mian)應該具有金屬光澤，表面(mian)發黑的銅或(huo)表面(mian)發白的鋁說明已被氧化。

第(di)三、在購(gou)買電(dian)線時應注意查看質(zhi)量(liang)合格證書。如果(guo)電(dian)線的(de)質(zhi)量(liang)合格，那么(me)其電(dian)線質(zhi)量(liang)應該(gai)也受過檢(jian)驗，不會(hui)有太大的(de)問題。
