不(bu)合格電線電纜(lan)的危害

電(dian)(dian)線電(dian)(dian)纜是用于(yu)傳輸電(dian)(dian)力、傳輸信息(xi)和實現電(dian)(dian)磁(ci)能(neng)量轉換的(de)一(yi)大(da)類電(dian)(dian)工產品(pin)。在抽查(cha)過程中，發現了大(da)量的(de)不合(he)格產品(pin)，這(zhe)些劣質產品(pin)給電(dian)(dian)力系統正常運行埋下諸多隱(yin)患。

1、標(biao)(biao)志不合(he)格(ge)的(de)電(dian)線電(dian)纜(lan)(lan)。標(biao)(biao)志是電(dian)線電(dian)纜(lan)(lan)使(shi)用識別(bie)(bie)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)志的(de)主(zhu)要內容是：產品型號(hao)、規格(ge)、標(biao)(biao)準號(hao)、廠名、產地等(deng)在一定的(de)標(biao)(biao)示(shi)間(jian)距內，當(dang)標(biao)(biao)志不合(he)格(ge)時(shi)，會造(zao)成施(shi)工(gong)人員識別(bie)(bie)錯誤，嚴重時(shi)會引發電(dian)氣事故。

2、結構(gou)尺寸不合格的(de)(de)(de)電線(xian)電纜。結構(gou)尺寸的(de)(de)(de)主要問題是護套(tao)(tao)厚(hou)度，絕(jue)(jue)緣厚(hou)度，當電纜的(de)(de)(de)護套(tao)(tao)和絕(jue)(jue)緣厚(hou)度不達標時(shi)，致(zhi)使電線(xian)電纜耐(nai)電氣強度會嚴(yan)重降低，導(dao)致(zhi)電線(xian)電纜的(de)(de)(de)使用壽(shou)命(ming)縮短，嚴(yan)重時(shi)可(ke)導(dao)致(zhi)電線(xian)電纜被擊穿，絕(jue)(jue)緣（護套(tao)(tao)）層起不到正常保護作用，從而(er)發生電氣短路和火(huo)災(zai)等(deng)現象。

3、護(hu)套(tao)式絕緣(yuan)(yuan)老化前(qian)的抗張強(qiang)(qiang)度(du)(du)、伸長(chang)(chang)率合格(ge)的電線電纜(lan)。絕緣(yuan)(yuan)護(hu)套(tao)老化前(qian)的抗張強(qiang)(qiang)度(du)(du)、伸長(chang)(chang)率不合格(ge)直接大大縮短(duan)電線電纜(lan)的工作用(yong)壽命，而且在(zai)施(shi)工或在(zai)長(chang)(chang)時間通電且溫度(du)(du)較(jiao)高的環境中(zhong)，極易出現絕緣(yuan)(yuan)體(ti)斷裂，致使帶電導體(ti)裸露，發生能觸電式短(duan)路危(wei)險。其不合格(ge)的主要原因是使用(yong)了再生料生產，以降低產品成本，二(er)是不具備(bei)生產資(zi)格(ge)小型企業。

4、導(dao)體(ti)電(dian)(dian)(dian)(dian)(dian)(dian)阻(zu)不合格的(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)線(xian)。導(dao)體(ti)電(dian)(dian)(dian)(dian)(dian)(dian)阻(zu)主(zhu)要(yao)是考核(he)電(dian)(dian)(dian)(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)的(de)(de)(de)(de)導(dao)體(ti)材料(liao)以及截(jie)面是否符合的(de)(de)(de)(de)重(zhong)要(yao)指標。當導(dao)體(ti)電(dian)(dian)(dian)(dian)(dian)(dian)阻(zu)超標時(shi)，就增大了(le)(le)電(dian)(dian)(dian)(dian)(dian)(dian)流在線(xian)路上通(tong)過時(shi)的(de)(de)(de)(de)損耗(hao)，加(jia)劇了(le)(le)電(dian)(dian)(dian)(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)的(de)(de)(de)(de)發(fa)熱(re)。導(dao)體(ti)電(dian)(dian)(dian)(dian)(dian)(dian)阻(zu)不合格的(de)(de)(de)(de)原因，主(zhu)要(yao)進企業為了(le)(le)降低成本，將(jiang)占原材料(liao)成本80%的(de)(de)(de)(de)銅材縮(suo)水，要(yao)么(me)降低導(dao)體(ti)的(de)(de)(de)(de)截(jie)面積，要(yao)么(me)使用含雜質過高的(de)(de)(de)(de)再生銅，這樣致使電(dian)(dian)(dian)(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)的(de)(de)(de)(de)導(dao)體(ti)電(dian)(dian)(dian)(dian)(dian)(dian)阻(zu)嚴重(zhong)超標，在使用過程中除(chu)易引發(fa)火(huo)災(zai)，還(huan)會加(jia)速包覆在電(dian)(dian)(dian)(dian)(dian)(dian)線(xian)外的(de)(de)(de)(de)絕緣層的(de)(de)(de)(de)老化。

在(zai)購買電(dian)線電(dian)纜的過程中(zhong)，消費者(zhe)應注意以下幾個事(shi)

第一、要觀(guan)(guan)察(cha)電線的(de)外(wai)觀(guan)(guan)。合格產品的(de)絕緣（護套）層柔軟、有韌性和伸縮性、表面(mian)層緊密、光滑(hua)、無粗糙感(gan)。如(ru)果包裹(guo)電線的(de)塑料很容(rong)易(yi)被(bei)剝去，則存在塑料強度不夠的(de)問(wen)題。

第二、要看電線的截面(mian)。合格產品的銅(tong)芯(xin)或鋁(lv)芯(xin)表(biao)(biao)面(mian)應該具(ju)有(you)金屬(shu)光澤，表(biao)(biao)面(mian)發黑的銅(tong)或表(biao)(biao)面(mian)發白的鋁(lv)說(shuo)明已(yi)被氧(yang)化。

第三、在購買電線時應注意查看(kan)質量合格(ge)證書。如果電線的(de)質量合格(ge)，那(nei)么其電線質量應該也受過檢驗，不會有太大的(de)問題。
