不合格電線電纜的(de)危害

電(dian)線(xian)電(dian)纜是用(yong)于傳(chuan)輸(shu)(shu)電(dian)力、傳(chuan)輸(shu)(shu)信息和實現電(dian)磁能量轉換的一大(da)類(lei)電(dian)工產品。在抽(chou)查過程中(zhong)，發現了大(da)量的不(bu)合(he)格產品，這些劣質產品給電(dian)力系統正常運行埋(mai)下諸多隱患。

1、標(biao)(biao)(biao)志(zhi)不(bu)合格的(de)電線(xian)(xian)電纜(lan)。標(biao)(biao)(biao)志(zhi)是電線(xian)(xian)電纜(lan)使(shi)用識別產(chan)品(pin)基本信息的(de)主(zhu)要途徑，根據標(biao)(biao)(biao)準(zhun)規定標(biao)(biao)(biao)志(zhi)的(de)主(zhu)要內容是：產(chan)品(pin)型號、規格、標(biao)(biao)(biao)準(zhun)號、廠(chang)名(ming)、產(chan)地等在一定的(de)標(biao)(biao)(biao)示間距(ju)內，當標(biao)(biao)(biao)志(zhi)不(bu)合格時(shi)，會(hui)造成施工人員識別錯誤，嚴重時(shi)會(hui)引(yin)發電氣(qi)事故。

2、結(jie)構尺(chi)寸(cun)不合格的(de)電(dian)線(xian)(xian)電(dian)纜(lan)(lan)。結(jie)構尺(chi)寸(cun)的(de)主要(yao)問題是護(hu)套(tao)(tao)厚度，絕(jue)(jue)緣厚度，當(dang)電(dian)纜(lan)(lan)的(de)護(hu)套(tao)(tao)和絕(jue)(jue)緣厚度不達標時，致(zhi)使電(dian)線(xian)(xian)電(dian)纜(lan)(lan)耐(nai)電(dian)氣強度會(hui)嚴(yan)(yan)重降低，導致(zhi)電(dian)線(xian)(xian)電(dian)纜(lan)(lan)的(de)使用壽命(ming)縮短，嚴(yan)(yan)重時可導致(zhi)電(dian)線(xian)(xian)電(dian)纜(lan)(lan)被擊穿，絕(jue)(jue)緣（護(hu)套(tao)(tao)）層起不到正常保護(hu)作用，從而發生電(dian)氣短路和火災(zai)等現象。

3、護(hu)套(tao)(tao)式絕緣(yuan)老化前的(de)(de)抗張強度、伸長(chang)率(lv)合格(ge)的(de)(de)電(dian)(dian)線(xian)電(dian)(dian)纜。絕緣(yuan)護(hu)套(tao)(tao)老化前的(de)(de)抗張強度、伸長(chang)率(lv)不合格(ge)直接大大縮(suo)短(duan)電(dian)(dian)線(xian)電(dian)(dian)纜的(de)(de)工作用壽命，而(er)且(qie)在(zai)施工或在(zai)長(chang)時間通電(dian)(dian)且(qie)溫度較(jiao)高的(de)(de)環境(jing)中，極易出現絕緣(yuan)體斷(duan)裂(lie)，致使帶電(dian)(dian)導體裸露，發(fa)生能觸電(dian)(dian)式短(duan)路危(wei)險。其(qi)不合格(ge)的(de)(de)主要原因是使用了(le)再生料生產(chan)，以降(jiang)低(di)產(chan)品(pin)成(cheng)本，二是不具備生產(chan)資格(ge)小型企業。

4、導體電(dian)(dian)(dian)(dian)阻(zu)(zu)不(bu)合(he)格的(de)電(dian)(dian)(dian)(dian)線。導體電(dian)(dian)(dian)(dian)阻(zu)(zu)主(zhu)要(yao)是考核電(dian)(dian)(dian)(dian)線電(dian)(dian)(dian)(dian)纜的(de)導體材(cai)料(liao)以及截(jie)面(mian)是否符合(he)的(de)重要(yao)指(zhi)標(biao)。當(dang)導體電(dian)(dian)(dian)(dian)阻(zu)(zu)超標(biao)時(shi)，就增大(da)了(le)電(dian)(dian)(dian)(dian)流在(zai)線路上通(tong)過(guo)時(shi)的(de)損耗，加劇(ju)了(le)電(dian)(dian)(dian)(dian)線電(dian)(dian)(dian)(dian)纜的(de)發熱。導體電(dian)(dian)(dian)(dian)阻(zu)(zu)不(bu)合(he)格的(de)原因，主(zhu)要(yao)進企業為了(le)降(jiang)低成本，將占原材(cai)料(liao)成本80%的(de)銅材(cai)縮水(shui)，要(yao)么降(jiang)低導體的(de)截(jie)面(mian)積，要(yao)么使(shi)(shi)用含雜質過(guo)高的(de)再生(sheng)銅，這樣致使(shi)(shi)電(dian)(dian)(dian)(dian)線電(dian)(dian)(dian)(dian)纜的(de)導體電(dian)(dian)(dian)(dian)阻(zu)(zu)嚴重超標(biao)，在(zai)使(shi)(shi)用過(guo)程中除易引發火(huo)災，還會加速包覆在(zai)電(dian)(dian)(dian)(dian)線外的(de)絕緣層(ceng)的(de)老化。

在(zai)購買電線電纜(lan)的過(guo)程中，消費(fei)者(zhe)應(ying)注意以下幾個事(shi)

第一、要觀察(cha)電(dian)線的(de)(de)外觀。合(he)格產品的(de)(de)絕緣（護套(tao)）層柔(rou)軟、有韌性和伸(shen)縮性、表面(mian)層緊密(mi)、光滑(hua)、無粗糙(cao)感。如果包裹電(dian)線的(de)(de)塑(su)料很容易被剝去(qu)，則(ze)存在塑(su)料強度(du)不夠的(de)(de)問題。

第二、要(yao)看電(dian)線的(de)(de)截面(mian)。合格產(chan)品的(de)(de)銅(tong)芯(xin)(xin)或(huo)鋁芯(xin)(xin)表(biao)面(mian)應該具有金屬(shu)光澤(ze)，表(biao)面(mian)發黑的(de)(de)銅(tong)或(huo)表(biao)面(mian)發白(bai)的(de)(de)鋁說明已被氧(yang)化。

第三(san)、在(zai)購買電線時(shi)應注意查看(kan)質(zhi)(zhi)量(liang)合格(ge)證書。如果電線的質(zhi)(zhi)量(liang)合格(ge)，那么其電線質(zhi)(zhi)量(liang)應該也受過(guo)檢驗，不會有太大的問題。
