不合格電(dian)線電(dian)纜的危害

電(dian)(dian)線(xian)電(dian)(dian)纜是用(yong)于傳輸電(dian)(dian)力(li)、傳輸信息和(he)實現(xian)電(dian)(dian)磁能量轉換的一大(da)類(lei)電(dian)(dian)工產(chan)品。在(zai)抽查過程中(zhong)，發現(xian)了大(da)量的不合(he)格產(chan)品，這些劣(lie)質產(chan)品給電(dian)(dian)力(li)系統(tong)正常運行埋下諸多隱患。

1、標(biao)(biao)(biao)志(zhi)(zhi)不合格的(de)(de)電(dian)線(xian)電(dian)纜。標(biao)(biao)(biao)志(zhi)(zhi)是電(dian)線(xian)電(dian)纜使(shi)用識別產品(pin)基(ji)本信息(xi)的(de)(de)主(zhu)要(yao)途徑，根據(ju)標(biao)(biao)(biao)準規(gui)定標(biao)(biao)(biao)志(zhi)(zhi)的(de)(de)主(zhu)要(yao)內(nei)容是：產品(pin)型號、規(gui)格、標(biao)(biao)(biao)準號、廠名、產地等(deng)在一定的(de)(de)標(biao)(biao)(biao)示間距內(nei)，當標(biao)(biao)(biao)志(zhi)(zhi)不合格時，會(hui)造成施工人員(yuan)識別錯誤，嚴重時會(hui)引(yin)發電(dian)氣事(shi)故。

2、結構尺(chi)(chi)寸(cun)不合格的電(dian)(dian)線電(dian)(dian)纜(lan)。結構尺(chi)(chi)寸(cun)的主要問題是(shi)護(hu)套厚度，絕緣厚度，當電(dian)(dian)纜(lan)的護(hu)套和(he)絕緣厚度不達標時，致使(shi)電(dian)(dian)線電(dian)(dian)纜(lan)耐電(dian)(dian)氣強度會嚴重(zhong)(zhong)降低(di)，導致電(dian)(dian)線電(dian)(dian)纜(lan)的使(shi)用壽命縮短(duan)，嚴重(zhong)(zhong)時可導致電(dian)(dian)線電(dian)(dian)纜(lan)被擊穿，絕緣（護(hu)套）層起不到(dao)正常保護(hu)作用，從(cong)而發生電(dian)(dian)氣短(duan)路和(he)火災等現象。

3、護套式(shi)絕(jue)緣老(lao)化(hua)前的(de)(de)(de)抗(kang)張(zhang)強度、伸長(chang)率合格(ge)的(de)(de)(de)電線電纜。絕(jue)緣護套老(lao)化(hua)前的(de)(de)(de)抗(kang)張(zhang)強度、伸長(chang)率不(bu)合格(ge)直接大大縮短(duan)電線電纜的(de)(de)(de)工作用壽命，而且在施工或在長(chang)時間通(tong)電且溫度較高的(de)(de)(de)環境中，極易出(chu)現絕(jue)緣體斷裂，致使(shi)帶電導體裸(luo)露，發生(sheng)(sheng)能觸電式(shi)短(duan)路(lu)危險。其不(bu)合格(ge)的(de)(de)(de)主要原(yuan)因是(shi)使(shi)用了(le)再生(sheng)(sheng)料生(sheng)(sheng)產(chan)，以(yi)降低產(chan)品成本，二(er)是(shi)不(bu)具備生(sheng)(sheng)產(chan)資(zi)格(ge)小型企(qi)業。

4、導(dao)體(ti)(ti)電(dian)(dian)(dian)阻(zu)(zu)不合(he)(he)格的(de)電(dian)(dian)(dian)線(xian)。導(dao)體(ti)(ti)電(dian)(dian)(dian)阻(zu)(zu)主(zhu)要(yao)是(shi)考核電(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)纜的(de)導(dao)體(ti)(ti)材(cai)料(liao)(liao)以及截面(mian)是(shi)否符合(he)(he)的(de)重要(yao)指標。當導(dao)體(ti)(ti)電(dian)(dian)(dian)阻(zu)(zu)超(chao)標時，就增大了電(dian)(dian)(dian)流(liu)在線(xian)路上通過(guo)時的(de)損耗(hao)，加(jia)劇(ju)了電(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)纜的(de)發(fa)熱。導(dao)體(ti)(ti)電(dian)(dian)(dian)阻(zu)(zu)不合(he)(he)格的(de)原(yuan)因，主(zhu)要(yao)進企業(ye)為了降低(di)成本(ben)，將占原(yuan)材(cai)料(liao)(liao)成本(ben)80%的(de)銅材(cai)縮水，要(yao)么降低(di)導(dao)體(ti)(ti)的(de)截面(mian)積，要(yao)么使用含(han)雜質(zhi)過(guo)高的(de)再(zai)生銅，這樣致(zhi)使電(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)纜的(de)導(dao)體(ti)(ti)電(dian)(dian)(dian)阻(zu)(zu)嚴(yan)重超(chao)標，在使用過(guo)程中(zhong)除(chu)易引發(fa)火災，還會(hui)加(jia)速包覆在電(dian)(dian)(dian)線(xian)外(wai)的(de)絕緣(yuan)層的(de)老化。

在(zai)購買電線(xian)電纜的過程中，消費者應注(zhu)意以下幾個事(shi)

第一、要(yao)觀察(cha)電(dian)線的(de)外觀。合(he)格產品的(de)絕緣（護套）層柔軟、有韌性和伸縮(suo)性、表(biao)面層緊密、光滑、無(wu)粗糙感。如(ru)果包裹電(dian)線的(de)塑(su)料很容易(yi)被剝去，則存(cun)在塑(su)料強(qiang)度不夠的(de)問題(ti)。

第(di)二、要看電(dian)線的(de)截(jie)面。合格產品(pin)的(de)銅芯或鋁(lv)芯表面應該具有金(jin)屬光澤，表面發黑的(de)銅或表面發白的(de)鋁(lv)說明(ming)已被氧(yang)化。

第(di)三、在購買電線(xian)時應(ying)注意查看質量合格(ge)(ge)證書。如果電線(xian)的(de)質量合格(ge)(ge)，那么其電線(xian)質量應(ying)該(gai)也受(shou)過檢驗，不(bu)會有太大的(de)問題(ti)。
