不合格電線電纜的危害

電(dian)(dian)(dian)線電(dian)(dian)(dian)纜是用于傳輸(shu)電(dian)(dian)(dian)力(li)、傳輸(shu)信息(xi)和(he)實現電(dian)(dian)(dian)磁能量轉換的(de)一(yi)大類(lei)電(dian)(dian)(dian)工產(chan)品。在(zai)抽查過程中，發(fa)現了大量的(de)不合(he)格(ge)產(chan)品，這些劣質產(chan)品給電(dian)(dian)(dian)力(li)系統正常運行埋下諸多隱患。

1、標志不合格(ge)的(de)(de)電(dian)(dian)線電(dian)(dian)纜。標志是電(dian)(dian)線電(dian)(dian)纜使用識別產(chan)品基本信息的(de)(de)主(zhu)要途徑，根據標準(zhun)規定(ding)標志的(de)(de)主(zhu)要內容是：產(chan)品型號、規格(ge)、標準(zhun)號、廠(chang)名、產(chan)地等(deng)在一定(ding)的(de)(de)標示間距內，當標志不合格(ge)時，會造(zao)成施工人員(yuan)識別錯(cuo)誤，嚴重時會引發(fa)電(dian)(dian)氣(qi)事(shi)故。

2、結(jie)構(gou)尺寸不合格的(de)電(dian)線電(dian)纜。結(jie)構(gou)尺寸的(de)主要問題(ti)是護套厚(hou)(hou)度，絕緣(yuan)(yuan)厚(hou)(hou)度，當電(dian)纜的(de)護套和(he)絕緣(yuan)(yuan)厚(hou)(hou)度不達標(biao)時，致使電(dian)線電(dian)纜耐電(dian)氣強度會嚴重降低，導致電(dian)線電(dian)纜的(de)使用(yong)壽(shou)命(ming)縮(suo)短，嚴重時可導致電(dian)線電(dian)纜被擊穿(chuan)，絕緣(yuan)(yuan)（護套）層起不到正常保(bao)護作用(yong)，從而發生電(dian)氣短路和(he)火災等現象。

3、護套式絕緣老化(hua)前(qian)的抗(kang)張強(qiang)度、伸長率(lv)合格(ge)的電線電纜(lan)。絕緣護套老化(hua)前(qian)的抗(kang)張強(qiang)度、伸長率(lv)不合格(ge)直接大大縮短電線電纜(lan)的工(gong)作用壽命，而且在施工(gong)或在長時(shi)間通電且溫(wen)度較高的環境中，極易出(chu)現絕緣體斷裂，致使帶電導體裸(luo)露，發生(sheng)(sheng)(sheng)能觸電式短路危險(xian)。其(qi)不合格(ge)的主要原因是使用了再生(sheng)(sheng)(sheng)料生(sheng)(sheng)(sheng)產(chan)，以(yi)降低(di)產(chan)品成本(ben)，二是不具備生(sheng)(sheng)(sheng)產(chan)資格(ge)小型(xing)企業。

4、導(dao)(dao)體(ti)電(dian)(dian)(dian)阻(zu)(zu)不合(he)(he)格(ge)(ge)的(de)電(dian)(dian)(dian)線(xian)。導(dao)(dao)體(ti)電(dian)(dian)(dian)阻(zu)(zu)主要(yao)是(shi)考核電(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)纜的(de)導(dao)(dao)體(ti)材料以及截(jie)面是(shi)否符(fu)合(he)(he)的(de)重(zhong)要(yao)指標(biao)。當導(dao)(dao)體(ti)電(dian)(dian)(dian)阻(zu)(zu)超標(biao)時，就增大了電(dian)(dian)(dian)流在(zai)線(xian)路(lu)上(shang)通過(guo)時的(de)損耗，加(jia)(jia)劇(ju)了電(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)纜的(de)發(fa)熱(re)。導(dao)(dao)體(ti)電(dian)(dian)(dian)阻(zu)(zu)不合(he)(he)格(ge)(ge)的(de)原(yuan)因，主要(yao)進(jin)企業為了降低成本，將占原(yuan)材料成本80%的(de)銅材縮水，要(yao)么降低導(dao)(dao)體(ti)的(de)截(jie)面積，要(yao)么使(shi)用含雜質過(guo)高的(de)再生銅，這樣致(zhi)使(shi)電(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)纜的(de)導(dao)(dao)體(ti)電(dian)(dian)(dian)阻(zu)(zu)嚴重(zhong)超標(biao)，在(zai)使(shi)用過(guo)程(cheng)中除(chu)易引發(fa)火災，還會加(jia)(jia)速包覆(fu)在(zai)電(dian)(dian)(dian)線(xian)外的(de)絕緣層的(de)老化。

在購買電線電纜的(de)過程(cheng)中，消(xiao)費者應注(zhu)意以下幾個事

第一、要觀察電線的(de)外觀。合格(ge)產品的(de)絕緣（護套）層柔軟(ruan)、有韌性和伸縮性、表(biao)面層緊密、光滑、無粗(cu)糙(cao)感。如果包裹電線的(de)塑(su)料(liao)很容(rong)易被(bei)剝去，則存在塑(su)料(liao)強度不夠的(de)問題(ti)。

第(di)二(er)、要(yao)看(kan)電線的(de)(de)截面。合格產品(pin)的(de)(de)銅(tong)芯(xin)或鋁芯(xin)表面應該具有金屬光澤，表面發黑(hei)的(de)(de)銅(tong)或表面發白的(de)(de)鋁說明已被氧化。

第(di)三、在購買(mai)電(dian)線時應(ying)注意查看質量合格(ge)證(zheng)書。如果電(dian)線的(de)質量合格(ge)，那么其電(dian)線質量應(ying)該也受過檢驗，不會(hui)有太大的(de)問題。
