不合(he)格電線電纜的(de)危害

電(dian)(dian)線電(dian)(dian)纜是用于傳輸(shu)電(dian)(dian)力、傳輸(shu)信息和實(shi)現(xian)電(dian)(dian)磁(ci)能量(liang)轉(zhuan)換的一大類(lei)電(dian)(dian)工產(chan)品(pin)(pin)。在抽查(cha)過(guo)程中，發(fa)現(xian)了大量(liang)的不(bu)合格產(chan)品(pin)(pin)，這些劣質產(chan)品(pin)(pin)給電(dian)(dian)力系統正常運(yun)行埋下諸多隱患(huan)。

1、標(biao)(biao)志(zhi)(zhi)(zhi)不(bu)合格(ge)的電(dian)(dian)(dian)線電(dian)(dian)(dian)纜。標(biao)(biao)志(zhi)(zhi)(zhi)是電(dian)(dian)(dian)線電(dian)(dian)(dian)纜使(shi)用識別產品基本信息(xi)的主要(yao)途徑，根據標(biao)(biao)準規(gui)定標(biao)(biao)志(zhi)(zhi)(zhi)的主要(yao)內容是：產品型號(hao)、規(gui)格(ge)、標(biao)(biao)準號(hao)、廠名、產地(di)等在一(yi)定的標(biao)(biao)示間(jian)距內，當標(biao)(biao)志(zhi)(zhi)(zhi)不(bu)合格(ge)時，會造成(cheng)施工人員識別錯(cuo)誤，嚴重時會引(yin)發電(dian)(dian)(dian)氣事故。

2、結構尺寸不(bu)合格的(de)電(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)纜。結構尺寸的(de)主(zhu)要問題是護套(tao)(tao)厚度，絕緣厚度，當(dang)電(dian)(dian)(dian)纜的(de)護套(tao)(tao)和(he)絕緣厚度不(bu)達(da)標時(shi)，致使(shi)電(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)纜耐電(dian)(dian)(dian)氣(qi)強(qiang)度會嚴(yan)重(zhong)降低，導(dao)致電(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)纜的(de)使(shi)用壽命縮短，嚴(yan)重(zhong)時(shi)可導(dao)致電(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)纜被擊(ji)穿，絕緣（護套(tao)(tao)）層起不(bu)到正常(chang)保護作(zuo)用，從而(er)發生電(dian)(dian)(dian)氣(qi)短路和(he)火(huo)災等現象。

3、護套(tao)式(shi)絕(jue)(jue)緣(yuan)老化(hua)前的(de)抗張強度(du)、伸(shen)(shen)長(chang)率(lv)合格(ge)(ge)的(de)電(dian)線(xian)電(dian)纜(lan)(lan)。絕(jue)(jue)緣(yuan)護套(tao)老化(hua)前的(de)抗張強度(du)、伸(shen)(shen)長(chang)率(lv)不(bu)(bu)合格(ge)(ge)直接大(da)大(da)縮短(duan)電(dian)線(xian)電(dian)纜(lan)(lan)的(de)工作(zuo)用壽命，而且在施工或在長(chang)時間(jian)通電(dian)且溫度(du)較高的(de)環(huan)境中，極易出現絕(jue)(jue)緣(yuan)體斷(duan)裂，致使帶電(dian)導(dao)體裸露，發生能觸電(dian)式(shi)短(duan)路危(wei)險。其不(bu)(bu)合格(ge)(ge)的(de)主要(yao)原因(yin)是(shi)使用了(le)再生料生產，以降低產品成本，二是(shi)不(bu)(bu)具備生產資格(ge)(ge)小型企業(ye)。

4、導(dao)(dao)(dao)體電(dian)(dian)阻(zu)不合格(ge)的(de)(de)(de)電(dian)(dian)線(xian)。導(dao)(dao)(dao)體電(dian)(dian)阻(zu)主要(yao)是考核電(dian)(dian)線(xian)電(dian)(dian)纜(lan)的(de)(de)(de)導(dao)(dao)(dao)體材料(liao)以及截面是否符合的(de)(de)(de)重(zhong)要(yao)指(zhi)標。當導(dao)(dao)(dao)體電(dian)(dian)阻(zu)超標時(shi)(shi)，就增大了(le)電(dian)(dian)流在(zai)線(xian)路上通過時(shi)(shi)的(de)(de)(de)損耗，加(jia)劇了(le)電(dian)(dian)線(xian)電(dian)(dian)纜(lan)的(de)(de)(de)發熱(re)。導(dao)(dao)(dao)體電(dian)(dian)阻(zu)不合格(ge)的(de)(de)(de)原(yuan)因，主要(yao)進企業為了(le)降低成本，將占原(yuan)材料(liao)成本80%的(de)(de)(de)銅(tong)材縮水，要(yao)么降低導(dao)(dao)(dao)體的(de)(de)(de)截面積，要(yao)么使用含雜質過高的(de)(de)(de)再生(sheng)銅(tong)，這樣致(zhi)使電(dian)(dian)線(xian)電(dian)(dian)纜(lan)的(de)(de)(de)導(dao)(dao)(dao)體電(dian)(dian)阻(zu)嚴重(zhong)超標，在(zai)使用過程(cheng)中除(chu)易引發火災，還會(hui)加(jia)速包(bao)覆在(zai)電(dian)(dian)線(xian)外(wai)的(de)(de)(de)絕緣層的(de)(de)(de)老化(hua)。

在購買電(dian)線(xian)電(dian)纜的過(guo)程(cheng)中，消費者應注(zhu)意以下幾個(ge)事

第一、要觀察(cha)電線的(de)外觀。合格產品的(de)絕(jue)緣（護(hu)套）層柔軟、有韌性和伸縮性、表面層緊密(mi)、光滑、無粗糙感(gan)。如(ru)果包(bao)裹電線的(de)塑料很容易被剝(bo)去，則存在塑料強度不夠(gou)的(de)問(wen)題(ti)。

第二(er)、要看(kan)電線的(de)截面。合格產品的(de)銅(tong)(tong)芯或鋁芯表面應該(gai)具有金屬光澤，表面發黑的(de)銅(tong)(tong)或表面發白的(de)鋁說明已被(bei)氧化。

第三、在購(gou)買電線時應注意查看質量(liang)合格(ge)證書。如果電線的(de)(de)質量(liang)合格(ge)，那么其電線質量(liang)應該也受過檢驗，不(bu)會有太大的(de)(de)問題。
