不合格(ge)電線電纜(lan)的(de)危害(hai)

電(dian)(dian)線電(dian)(dian)纜是用(yong)于傳輸(shu)電(dian)(dian)力、傳輸(shu)信(xin)息和實現(xian)電(dian)(dian)磁能(neng)量轉換的一大類電(dian)(dian)工產品。在抽查過(guo)程中，發現(xian)了大量的不合格產品，這些(xie)劣(lie)質(zhi)產品給電(dian)(dian)力系統(tong)正(zheng)常運行埋(mai)下(xia)諸多隱患。

1、標(biao)(biao)志(zhi)不合(he)(he)格的(de)電(dian)線電(dian)纜。標(biao)(biao)志(zhi)是電(dian)線電(dian)纜使用識別產品基本信息的(de)主(zhu)要途徑(jing)，根據標(biao)(biao)準規定標(biao)(biao)志(zhi)的(de)主(zhu)要內(nei)容是：產品型(xing)號、規格、標(biao)(biao)準號、廠名、產地等在一定的(de)標(biao)(biao)示間距內(nei)，當標(biao)(biao)志(zhi)不合(he)(he)格時，會造(zao)成施工人(ren)員識別錯誤，嚴重時會引發(fa)電(dian)氣(qi)事故。

2、結構尺(chi)寸不(bu)合格的電(dian)(dian)線(xian)電(dian)(dian)纜(lan)(lan)。結構尺(chi)寸的主(zhu)要問(wen)題是(shi)護(hu)(hu)套厚度(du)(du)，絕緣(yuan)厚度(du)(du)，當電(dian)(dian)纜(lan)(lan)的護(hu)(hu)套和絕緣(yuan)厚度(du)(du)不(bu)達標(biao)時(shi)，致(zhi)使電(dian)(dian)線(xian)電(dian)(dian)纜(lan)(lan)耐電(dian)(dian)氣強度(du)(du)會嚴(yan)重降低，導致(zhi)電(dian)(dian)線(xian)電(dian)(dian)纜(lan)(lan)的使用壽命(ming)縮短，嚴(yan)重時(shi)可導致(zhi)電(dian)(dian)線(xian)電(dian)(dian)纜(lan)(lan)被擊穿(chuan)，絕緣(yuan)（護(hu)(hu)套）層起不(bu)到正常保護(hu)(hu)作用，從(cong)而發生電(dian)(dian)氣短路和火災等現象。

3、護套式絕(jue)(jue)緣老化前(qian)的(de)(de)抗張強(qiang)度、伸長(chang)率合(he)(he)格的(de)(de)電(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)纜。絕(jue)(jue)緣護套老化前(qian)的(de)(de)抗張強(qiang)度、伸長(chang)率不(bu)(bu)(bu)合(he)(he)格直接大大縮短(duan)電(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)纜的(de)(de)工作用壽命，而且(qie)在施(shi)工或在長(chang)時間(jian)通電(dian)(dian)(dian)且(qie)溫度較高的(de)(de)環(huan)境中(zhong)，極易出現絕(jue)(jue)緣體斷(duan)裂，致使帶電(dian)(dian)(dian)導體裸(luo)露，發(fa)生(sheng)能觸電(dian)(dian)(dian)式短(duan)路危險。其(qi)不(bu)(bu)(bu)合(he)(he)格的(de)(de)主要原因是使用了(le)再生(sheng)料(liao)生(sheng)產，以降低產品成(cheng)本(ben)，二是不(bu)(bu)(bu)具(ju)備生(sheng)產資(zi)格小型企業(ye)。

4、導(dao)體電(dian)(dian)(dian)阻不(bu)合格(ge)的(de)(de)電(dian)(dian)(dian)線。導(dao)體電(dian)(dian)(dian)阻主要是考核電(dian)(dian)(dian)線電(dian)(dian)(dian)纜的(de)(de)導(dao)體材料以及(ji)截面是否符合的(de)(de)重(zhong)(zhong)要指(zhi)標。當導(dao)體電(dian)(dian)(dian)阻超(chao)(chao)標時，就(jiu)增(zeng)大了電(dian)(dian)(dian)流在(zai)線路上(shang)通(tong)過時的(de)(de)損(sun)耗，加劇了電(dian)(dian)(dian)線電(dian)(dian)(dian)纜的(de)(de)發熱。導(dao)體電(dian)(dian)(dian)阻不(bu)合格(ge)的(de)(de)原因，主要進企業為(wei)了降低(di)成本，將占原材料成本80%的(de)(de)銅材縮水，要么降低(di)導(dao)體的(de)(de)截面積，要么使(shi)用(yong)含雜質(zhi)過高的(de)(de)再生銅，這樣致使(shi)電(dian)(dian)(dian)線電(dian)(dian)(dian)纜的(de)(de)導(dao)體電(dian)(dian)(dian)阻嚴重(zhong)(zhong)超(chao)(chao)標，在(zai)使(shi)用(yong)過程中(zhong)除易引發火(huo)災，還(huan)會加速包覆在(zai)電(dian)(dian)(dian)線外的(de)(de)絕緣層的(de)(de)老化。

在購(gou)買電線(xian)電纜的過程(cheng)中(zhong)，消費者應注(zhu)意(yi)以(yi)下幾個事(shi)

第一(yi)、要觀察電線的(de)(de)外觀。合格產品的(de)(de)絕緣（護套(tao)）層柔軟、有韌性和伸(shen)縮(suo)性、表(biao)面層緊(jin)密(mi)、光滑、無粗糙(cao)感(gan)。如果包裹(guo)電線的(de)(de)塑料很容易被剝去，則存在塑料強度(du)不夠(gou)的(de)(de)問題。

第二、要看電線的(de)截(jie)面。合格(ge)產品(pin)的(de)銅芯或鋁(lv)芯表面應該(gai)具有金(jin)屬光(guang)澤，表面發(fa)黑的(de)銅或表面發(fa)白的(de)鋁(lv)說明已被(bei)氧化。

第三、在購(gou)買電(dian)線時應注意查(cha)看(kan)質量(liang)合(he)(he)格證書。如果電(dian)線的質量(liang)合(he)(he)格，那么其電(dian)線質量(liang)應該也受(shou)過檢驗，不會有太大的問題。
