不合格電線(xian)電纜的危害

電(dian)線(xian)電(dian)纜是用于傳輸(shu)電(dian)力、傳輸(shu)信息和實現(xian)電(dian)磁能(neng)量(liang)轉換的(de)一(yi)大類電(dian)工(gong)產品。在抽查(cha)過程(cheng)中，發現(xian)了大量(liang)的(de)不合格產品，這些劣質產品給電(dian)力系統(tong)正常運行埋下諸多(duo)隱患(huan)。

1、標(biao)(biao)志不(bu)合格的(de)(de)電(dian)線(xian)電(dian)纜。標(biao)(biao)志是(shi)電(dian)線(xian)電(dian)纜使用識(shi)別產品(pin)基(ji)本信息的(de)(de)主(zhu)(zhu)要途徑，根(gen)據(ju)標(biao)(biao)準規(gui)定標(biao)(biao)志的(de)(de)主(zhu)(zhu)要內容是(shi)：產品(pin)型號(hao)、規(gui)格、標(biao)(biao)準號(hao)、廠名、產地等在(zai)一(yi)定的(de)(de)標(biao)(biao)示(shi)間距內，當標(biao)(biao)志不(bu)合格時，會(hui)(hui)造(zao)成(cheng)施工(gong)人(ren)員識(shi)別錯誤，嚴重(zhong)時會(hui)(hui)引發電(dian)氣事故。

2、結(jie)構(gou)尺寸不合格的(de)電(dian)線(xian)電(dian)纜(lan)(lan)。結(jie)構(gou)尺寸的(de)主(zhu)要問題是護套厚度(du)，絕緣(yuan)厚度(du)，當電(dian)纜(lan)(lan)的(de)護套和絕緣(yuan)厚度(du)不達標時(shi)(shi)，致使(shi)電(dian)線(xian)電(dian)纜(lan)(lan)耐(nai)電(dian)氣(qi)強度(du)會(hui)嚴(yan)重(zhong)降低，導致電(dian)線(xian)電(dian)纜(lan)(lan)的(de)使(shi)用壽命(ming)縮短，嚴(yan)重(zhong)時(shi)(shi)可導致電(dian)線(xian)電(dian)纜(lan)(lan)被擊穿，絕緣(yuan)（護套）層起(qi)不到正常保(bao)護作用，從而發生電(dian)氣(qi)短路和火災等現象。

3、護套式絕緣老(lao)化(hua)前(qian)的(de)(de)抗(kang)張(zhang)強(qiang)(qiang)度(du)、伸長(chang)率合格(ge)(ge)(ge)的(de)(de)電線(xian)電纜。絕緣護套老(lao)化(hua)前(qian)的(de)(de)抗(kang)張(zhang)強(qiang)(qiang)度(du)、伸長(chang)率不(bu)合格(ge)(ge)(ge)直接(jie)大大縮短電線(xian)電纜的(de)(de)工(gong)作用(yong)壽命，而且在施工(gong)或在長(chang)時(shi)間(jian)通電且溫度(du)較(jiao)高(gao)的(de)(de)環境中，極易(yi)出現絕緣體(ti)斷裂，致(zhi)使帶電導(dao)體(ti)裸露，發生(sheng)(sheng)(sheng)能觸(chu)電式短路危(wei)險。其不(bu)合格(ge)(ge)(ge)的(de)(de)主要原因(yin)是使用(yong)了再生(sheng)(sheng)(sheng)料生(sheng)(sheng)(sheng)產(chan)(chan)，以(yi)降(jiang)低產(chan)(chan)品(pin)成本(ben)，二是不(bu)具備(bei)生(sheng)(sheng)(sheng)產(chan)(chan)資格(ge)(ge)(ge)小型企(qi)業。

4、導(dao)(dao)體(ti)電(dian)(dian)(dian)阻(zu)(zu)不合格的(de)(de)電(dian)(dian)(dian)線。導(dao)(dao)體(ti)電(dian)(dian)(dian)阻(zu)(zu)主(zhu)(zhu)要是(shi)考核(he)電(dian)(dian)(dian)線電(dian)(dian)(dian)纜的(de)(de)導(dao)(dao)體(ti)材(cai)料以及截(jie)面是(shi)否(fou)符合的(de)(de)重(zhong)要指標。當導(dao)(dao)體(ti)電(dian)(dian)(dian)阻(zu)(zu)超(chao)標時，就增大(da)了電(dian)(dian)(dian)流在(zai)線路(lu)上通過(guo)時的(de)(de)損(sun)耗，加劇了電(dian)(dian)(dian)線電(dian)(dian)(dian)纜的(de)(de)發熱。導(dao)(dao)體(ti)電(dian)(dian)(dian)阻(zu)(zu)不合格的(de)(de)原(yuan)因，主(zhu)(zhu)要進(jin)企業為了降低成本，將(jiang)占(zhan)原(yuan)材(cai)料成本80%的(de)(de)銅材(cai)縮水，要么降低導(dao)(dao)體(ti)的(de)(de)截(jie)面積，要么使(shi)用含雜(za)質(zhi)過(guo)高(gao)的(de)(de)再生銅，這樣(yang)致(zhi)使(shi)電(dian)(dian)(dian)線電(dian)(dian)(dian)纜的(de)(de)導(dao)(dao)體(ti)電(dian)(dian)(dian)阻(zu)(zu)嚴重(zhong)超(chao)標，在(zai)使(shi)用過(guo)程中(zhong)除易引發火災，還(huan)會加速包覆在(zai)電(dian)(dian)(dian)線外的(de)(de)絕緣(yuan)層的(de)(de)老化(hua)。

在購買電(dian)線(xian)電(dian)纜(lan)的過程中(zhong)，消費(fei)者應注意(yi)以下幾個事

第一、要(yao)觀(guan)察電線的(de)外(wai)觀(guan)。合(he)格產(chan)品的(de)絕緣（護套）層柔軟、有韌性(xing)和伸縮性(xing)、表面層緊(jin)密、光滑、無(wu)粗(cu)糙感。如果包(bao)裹電線的(de)塑料(liao)很容易被剝去，則存在塑料(liao)強度(du)不夠的(de)問題。

第二、要看電線的(de)(de)截(jie)面(mian)。合格(ge)產(chan)品(pin)的(de)(de)銅芯或鋁(lv)芯表(biao)面(mian)應該具有金屬(shu)光(guang)澤，表(biao)面(mian)發黑的(de)(de)銅或表(biao)面(mian)發白(bai)的(de)(de)鋁(lv)說明(ming)已被氧化。

第三、在購買電線時應(ying)注意(yi)查看(kan)質(zhi)(zhi)量合(he)格證(zheng)書。如果電線的質(zhi)(zhi)量合(he)格，那么(me)其電線質(zhi)(zhi)量應(ying)該也受(shou)過檢驗，不會(hui)有太大的問題。
