不合格電(dian)線(xian)電(dian)纜(lan)的危害

電(dian)(dian)(dian)線電(dian)(dian)(dian)纜是(shi)用于(yu)傳(chuan)輸電(dian)(dian)(dian)力、傳(chuan)輸信息和實現(xian)電(dian)(dian)(dian)磁能(neng)量轉換的一大類電(dian)(dian)(dian)工(gong)產(chan)品(pin)。在抽查(cha)過程中(zhong)，發(fa)現(xian)了大量的不(bu)合(he)格(ge)產(chan)品(pin)，這些劣(lie)質產(chan)品(pin)給(gei)電(dian)(dian)(dian)力系統正(zheng)常運行埋下諸多隱患。

1、標(biao)志(zhi)不合格(ge)的(de)電(dian)線電(dian)纜。標(biao)志(zhi)是電(dian)線電(dian)纜使用識別產(chan)品(pin)基(ji)本(ben)信息(xi)的(de)主(zhu)要途徑，根據(ju)標(biao)準(zhun)規定標(biao)志(zhi)的(de)主(zhu)要內容是：產(chan)品(pin)型號、規格(ge)、標(biao)準(zhun)號、廠名、產(chan)地等在一(yi)定的(de)標(biao)示間距(ju)內，當(dang)標(biao)志(zhi)不合格(ge)時(shi)，會造(zao)成施工人員(yuan)識別錯誤，嚴重時(shi)會引發(fa)電(dian)氣事故。

2、結構尺寸不合格的電(dian)(dian)(dian)(dian)線電(dian)(dian)(dian)(dian)纜(lan)。結構尺寸的主(zhu)要問題是護(hu)套厚(hou)(hou)度，絕(jue)緣(yuan)(yuan)厚(hou)(hou)度，當電(dian)(dian)(dian)(dian)纜(lan)的護(hu)套和絕(jue)緣(yuan)(yuan)厚(hou)(hou)度不達標時，致使電(dian)(dian)(dian)(dian)線電(dian)(dian)(dian)(dian)纜(lan)耐電(dian)(dian)(dian)(dian)氣強度會嚴(yan)(yan)重(zhong)降低(di)，導致電(dian)(dian)(dian)(dian)線電(dian)(dian)(dian)(dian)纜(lan)的使用壽命縮短(duan)，嚴(yan)(yan)重(zhong)時可導致電(dian)(dian)(dian)(dian)線電(dian)(dian)(dian)(dian)纜(lan)被(bei)擊穿，絕(jue)緣(yuan)(yuan)（護(hu)套）層起(qi)不到正常(chang)保護(hu)作用，從(cong)而發生電(dian)(dian)(dian)(dian)氣短(duan)路和火災等現象。

3、護套(tao)(tao)式絕(jue)緣老化(hua)前的(de)(de)(de)抗張強度、伸長率合格的(de)(de)(de)電(dian)線(xian)(xian)電(dian)纜(lan)。絕(jue)緣護套(tao)(tao)老化(hua)前的(de)(de)(de)抗張強度、伸長率不(bu)合格直接大大縮(suo)短電(dian)線(xian)(xian)電(dian)纜(lan)的(de)(de)(de)工作用壽命(ming)，而且在施工或在長時(shi)間(jian)通電(dian)且溫度較(jiao)高的(de)(de)(de)環境中，極易出現絕(jue)緣體斷裂，致使帶電(dian)導體裸露，發生能觸電(dian)式短路危險。其不(bu)合格的(de)(de)(de)主要原因是使用了(le)再生料(liao)生產(chan)，以降低產(chan)品(pin)成本，二是不(bu)具備(bei)生產(chan)資格小型企業。

4、導(dao)體(ti)電(dian)(dian)阻(zu)不合(he)(he)格(ge)的(de)電(dian)(dian)線。導(dao)體(ti)電(dian)(dian)阻(zu)主(zhu)要(yao)是考核電(dian)(dian)線電(dian)(dian)纜的(de)導(dao)體(ti)材(cai)料(liao)以及截(jie)(jie)面(mian)是否符合(he)(he)的(de)重要(yao)指標(biao)(biao)。當導(dao)體(ti)電(dian)(dian)阻(zu)超標(biao)(biao)時(shi)(shi)，就增(zeng)大了電(dian)(dian)流(liu)在線路上通過(guo)時(shi)(shi)的(de)損(sun)耗，加劇(ju)了電(dian)(dian)線電(dian)(dian)纜的(de)發熱(re)。導(dao)體(ti)電(dian)(dian)阻(zu)不合(he)(he)格(ge)的(de)原(yuan)因，主(zhu)要(yao)進企業為了降低成本(ben)，將占(zhan)原(yuan)材(cai)料(liao)成本(ben)80%的(de)銅材(cai)縮(suo)水，要(yao)么降低導(dao)體(ti)的(de)截(jie)(jie)面(mian)積，要(yao)么使用含雜質(zhi)過(guo)高(gao)的(de)再生銅，這樣致使電(dian)(dian)線電(dian)(dian)纜的(de)導(dao)體(ti)電(dian)(dian)阻(zu)嚴重超標(biao)(biao)，在使用過(guo)程中(zhong)除易引發火災，還會加速(su)包覆在電(dian)(dian)線外的(de)絕緣(yuan)層(ceng)的(de)老化(hua)。

在購買(mai)電(dian)線電(dian)纜(lan)的過程中，消費(fei)者應注意以下幾個事(shi)

第一(yi)、要觀(guan)察(cha)電線(xian)的(de)(de)外(wai)觀(guan)。合(he)格產品的(de)(de)絕緣（護套）層(ceng)柔軟、有韌性(xing)和伸縮性(xing)、表面層(ceng)緊密、光滑、無粗糙感(gan)。如果包裹電線(xian)的(de)(de)塑料很(hen)容易被剝去(qu)，則存在(zai)塑料強度不夠的(de)(de)問(wen)題。

第二、要看電線的(de)截面。合格產品的(de)銅(tong)芯或鋁芯表面應該具有(you)金屬(shu)光澤，表面發黑(hei)的(de)銅(tong)或表面發白的(de)鋁說明已被氧化。

第三、在(zai)購買電線(xian)時應注意查看質(zhi)量合(he)格證書(shu)。如果(guo)電線(xian)的質(zhi)量合(he)格，那(nei)么其電線(xian)質(zhi)量應該(gai)也受過檢驗，不會有太大的問題。
