不合格電(dian)線(xian)電(dian)纜的(de)危(wei)害(hai)

電(dian)(dian)線電(dian)(dian)纜是用于(yu)傳輸(shu)(shu)電(dian)(dian)力、傳輸(shu)(shu)信(xin)息(xi)和實現電(dian)(dian)磁能量轉換(huan)的一大類電(dian)(dian)工(gong)產(chan)品。在抽查過(guo)程中，發現了(le)大量的不(bu)合格產(chan)品，這些劣質(zhi)產(chan)品給(gei)電(dian)(dian)力系(xi)統正(zheng)常運行埋下諸多(duo)隱患。

1、標(biao)(biao)志(zhi)不合格的電線(xian)電纜(lan)。標(biao)(biao)志(zhi)是電線(xian)電纜(lan)使用識別(bie)產品基(ji)本信息的主要(yao)途徑，根據標(biao)(biao)準規定標(biao)(biao)志(zhi)的主要(yao)內(nei)容是：產品型號、規格、標(biao)(biao)準號、廠名(ming)、產地等(deng)在(zai)一定的標(biao)(biao)示(shi)間距內(nei)，當標(biao)(biao)志(zhi)不合格時(shi)，會(hui)造成施(shi)工人員(yuan)識別(bie)錯誤，嚴重時(shi)會(hui)引發電氣事(shi)故(gu)。

2、結(jie)構尺(chi)寸不(bu)合格的電(dian)(dian)線(xian)電(dian)(dian)纜。結(jie)構尺(chi)寸的主(zhu)要問(wen)題是護套厚度，絕(jue)緣(yuan)厚度，當電(dian)(dian)纜的護套和絕(jue)緣(yuan)厚度不(bu)達標時，致使電(dian)(dian)線(xian)電(dian)(dian)纜耐電(dian)(dian)氣強度會(hui)嚴(yan)重降低(di)，導(dao)致電(dian)(dian)線(xian)電(dian)(dian)纜的使用壽命縮短，嚴(yan)重時可(ke)導(dao)致電(dian)(dian)線(xian)電(dian)(dian)纜被(bei)擊穿，絕(jue)緣(yuan)（護套）層起不(bu)到正常保護作用，從而(er)發生電(dian)(dian)氣短路和火災等現象。

3、護套式絕緣(yuan)(yuan)老化(hua)(hua)前的抗張(zhang)強度、伸長率合格(ge)(ge)的電(dian)(dian)(dian)線電(dian)(dian)(dian)纜。絕緣(yuan)(yuan)護套老化(hua)(hua)前的抗張(zhang)強度、伸長率不合格(ge)(ge)直接(jie)大(da)(da)大(da)(da)縮(suo)短電(dian)(dian)(dian)線電(dian)(dian)(dian)纜的工(gong)作(zuo)用(yong)(yong)壽命，而且在施工(gong)或在長時間通電(dian)(dian)(dian)且溫(wen)度較高的環境中，極易出現絕緣(yuan)(yuan)體斷裂，致使(shi)帶電(dian)(dian)(dian)導(dao)體裸露，發生能觸電(dian)(dian)(dian)式短路(lu)危險。其不合格(ge)(ge)的主要(yao)原因是使(shi)用(yong)(yong)了再(zai)生料生產(chan)，以降(jiang)低(di)產(chan)品成本，二是不具(ju)備生產(chan)資格(ge)(ge)小型企業。

4、導(dao)體電(dian)(dian)阻(zu)(zu)(zu)不合(he)格(ge)(ge)的(de)(de)(de)(de)電(dian)(dian)線(xian)。導(dao)體電(dian)(dian)阻(zu)(zu)(zu)主(zhu)要(yao)是考核(he)電(dian)(dian)線(xian)電(dian)(dian)纜的(de)(de)(de)(de)導(dao)體材料(liao)以及截(jie)面是否(fou)符(fu)合(he)的(de)(de)(de)(de)重要(yao)指(zhi)標。當(dang)導(dao)體電(dian)(dian)阻(zu)(zu)(zu)超標時(shi)，就增大了(le)電(dian)(dian)流在線(xian)路(lu)上(shang)通過時(shi)的(de)(de)(de)(de)損耗，加(jia)劇(ju)了(le)電(dian)(dian)線(xian)電(dian)(dian)纜的(de)(de)(de)(de)發熱(re)。導(dao)體電(dian)(dian)阻(zu)(zu)(zu)不合(he)格(ge)(ge)的(de)(de)(de)(de)原因(yin)，主(zhu)要(yao)進企業為了(le)降(jiang)低成(cheng)本，將占原材料(liao)成(cheng)本80%的(de)(de)(de)(de)銅材縮水，要(yao)么降(jiang)低導(dao)體的(de)(de)(de)(de)截(jie)面積，要(yao)么使(shi)用(yong)含雜質過高的(de)(de)(de)(de)再生(sheng)銅，這樣致使(shi)電(dian)(dian)線(xian)電(dian)(dian)纜的(de)(de)(de)(de)導(dao)體電(dian)(dian)阻(zu)(zu)(zu)嚴(yan)重超標，在使(shi)用(yong)過程中除易(yi)引發火災，還會加(jia)速包(bao)覆在電(dian)(dian)線(xian)外(wai)的(de)(de)(de)(de)絕(jue)緣層的(de)(de)(de)(de)老化。

在(zai)購買電線電纜的過(guo)程(cheng)中，消費者應注意(yi)以下幾個(ge)事

第一(yi)、要觀(guan)察(cha)電線的外觀(guan)。合格產品(pin)的絕緣（護套）層柔軟、有韌性和(he)伸縮性、表面層緊(jin)密、光(guang)滑、無(wu)粗(cu)糙感。如果包裹(guo)電線的塑料很容易被剝去，則存(cun)在(zai)塑料強度不夠(gou)的問題。

第(di)二、要看(kan)電線(xian)的截面。合(he)格產品的銅(tong)芯或鋁芯表面應該具(ju)有金屬光澤，表面發黑的銅(tong)或表面發白(bai)的鋁說明已被氧化。

第(di)三(san)、在購(gou)買電(dian)線時應注意查(cha)看(kan)質(zhi)量合(he)格證書。如果電(dian)線的質(zhi)量合(he)格，那么其電(dian)線質(zhi)量應該也受過檢驗，不會(hui)有太(tai)大的問題。
