不(bu)合格電線電纜的危害

電(dian)(dian)線電(dian)(dian)纜是用于傳(chuan)輸(shu)電(dian)(dian)力、傳(chuan)輸(shu)信息(xi)和實現電(dian)(dian)磁能量(liang)轉(zhuan)換的(de)一大(da)(da)類電(dian)(dian)工產(chan)(chan)品。在抽查(cha)過程(cheng)中，發現了大(da)(da)量(liang)的(de)不合(he)格(ge)產(chan)(chan)品，這些劣質產(chan)(chan)品給(gei)電(dian)(dian)力系統正常運行埋下諸多(duo)隱患。

1、標(biao)(biao)(biao)(biao)志(zhi)不(bu)合格(ge)的(de)電(dian)線電(dian)纜(lan)(lan)。標(biao)(biao)(biao)(biao)志(zhi)是(shi)電(dian)線電(dian)纜(lan)(lan)使用識別產(chan)品基本信(xin)息(xi)的(de)主要途(tu)徑，根據(ju)標(biao)(biao)(biao)(biao)準(zhun)(zhun)規定標(biao)(biao)(biao)(biao)志(zhi)的(de)主要內(nei)容是(shi)：產(chan)品型號、規格(ge)、標(biao)(biao)(biao)(biao)準(zhun)(zhun)號、廠名、產(chan)地(di)等(deng)在一定的(de)標(biao)(biao)(biao)(biao)示間距內(nei)，當標(biao)(biao)(biao)(biao)志(zhi)不(bu)合格(ge)時(shi)，會造成施工(gong)人員識別錯誤，嚴重時(shi)會引發電(dian)氣事故。

2、結構尺寸不合格的電(dian)線電(dian)纜。結構尺寸的主要問題是護套厚(hou)度(du)，絕(jue)緣厚(hou)度(du)，當電(dian)纜的護套和(he)絕(jue)緣厚(hou)度(du)不達標時(shi)，致使(shi)電(dian)線電(dian)纜耐電(dian)氣(qi)強度(du)會嚴(yan)重降(jiang)低，導致電(dian)線電(dian)纜的使(shi)用壽命縮短，嚴(yan)重時(shi)可導致電(dian)線電(dian)纜被擊穿，絕(jue)緣（護套）層起不到(dao)正常(chang)保(bao)護作用，從而(er)發生(sheng)電(dian)氣(qi)短路和(he)火災等(deng)現(xian)象。

3、護(hu)套(tao)式絕緣(yuan)(yuan)老(lao)化(hua)前(qian)的(de)(de)抗張強度、伸長(chang)(chang)率合格(ge)的(de)(de)電(dian)(dian)線電(dian)(dian)纜。絕緣(yuan)(yuan)護(hu)套(tao)老(lao)化(hua)前(qian)的(de)(de)抗張強度、伸長(chang)(chang)率不合格(ge)直(zhi)接大大縮(suo)短(duan)電(dian)(dian)線電(dian)(dian)纜的(de)(de)工作(zuo)用壽命(ming)，而且在施工或(huo)在長(chang)(chang)時間通(tong)電(dian)(dian)且溫度較高的(de)(de)環境中，極易出(chu)現絕緣(yuan)(yuan)體(ti)斷(duan)裂，致使帶電(dian)(dian)導體(ti)裸露(lu)，發生能(neng)觸電(dian)(dian)式短(duan)路危險。其不合格(ge)的(de)(de)主要原因是使用了再生料生產(chan)，以降低(di)產(chan)品成(cheng)本，二(er)是不具備生產(chan)資格(ge)小(xiao)型企業。

4、導(dao)(dao)(dao)(dao)體(ti)(ti)電(dian)(dian)(dian)(dian)阻(zu)不(bu)合格的(de)(de)電(dian)(dian)(dian)(dian)線(xian)(xian)。導(dao)(dao)(dao)(dao)體(ti)(ti)電(dian)(dian)(dian)(dian)阻(zu)主要(yao)是(shi)考核電(dian)(dian)(dian)(dian)線(xian)(xian)電(dian)(dian)(dian)(dian)纜(lan)的(de)(de)導(dao)(dao)(dao)(dao)體(ti)(ti)材(cai)料以及截面是(shi)否符合的(de)(de)重(zhong)要(yao)指標(biao)(biao)。當導(dao)(dao)(dao)(dao)體(ti)(ti)電(dian)(dian)(dian)(dian)阻(zu)超標(biao)(biao)時，就增(zeng)大了(le)電(dian)(dian)(dian)(dian)流在(zai)線(xian)(xian)路(lu)上(shang)通過(guo)時的(de)(de)損耗，加劇了(le)電(dian)(dian)(dian)(dian)線(xian)(xian)電(dian)(dian)(dian)(dian)纜(lan)的(de)(de)發熱。導(dao)(dao)(dao)(dao)體(ti)(ti)電(dian)(dian)(dian)(dian)阻(zu)不(bu)合格的(de)(de)原因(yin)，主要(yao)進企業為了(le)降低成本，將占(zhan)原材(cai)料成本80%的(de)(de)銅(tong)材(cai)縮水，要(yao)么(me)降低導(dao)(dao)(dao)(dao)體(ti)(ti)的(de)(de)截面積，要(yao)么(me)使(shi)用(yong)含雜質過(guo)高的(de)(de)再生銅(tong)，這樣致使(shi)電(dian)(dian)(dian)(dian)線(xian)(xian)電(dian)(dian)(dian)(dian)纜(lan)的(de)(de)導(dao)(dao)(dao)(dao)體(ti)(ti)電(dian)(dian)(dian)(dian)阻(zu)嚴重(zhong)超標(biao)(biao)，在(zai)使(shi)用(yong)過(guo)程中(zhong)除易(yi)引發火災，還會加速(su)包覆在(zai)電(dian)(dian)(dian)(dian)線(xian)(xian)外的(de)(de)絕(jue)緣(yuan)層的(de)(de)老化。

在購買電線電纜的過(guo)程中，消(xiao)費(fei)者應注意以下(xia)幾個事

第一、要(yao)觀察電(dian)線的外觀。合格產(chan)品的絕(jue)緣（護套）層柔軟、有韌(ren)性和伸縮性、表(biao)面層緊密、光滑(hua)、無粗糙感。如果包裹電(dian)線的塑料很容易被剝去，則存在塑料強度(du)不夠的問(wen)題。

第二(er)、要看電線的(de)截面(mian)。合(he)格(ge)產品的(de)銅芯(xin)或(huo)鋁芯(xin)表面(mian)應(ying)該具有金(jin)屬光澤，表面(mian)發黑的(de)銅或(huo)表面(mian)發白的(de)鋁說明已(yi)被氧化。

第三、在購買電(dian)(dian)線(xian)(xian)時應(ying)(ying)注(zhu)意(yi)查(cha)看質量合(he)格證書(shu)。如果電(dian)(dian)線(xian)(xian)的(de)質量合(he)格，那么其電(dian)(dian)線(xian)(xian)質量應(ying)(ying)該也(ye)受過檢(jian)驗，不會(hui)有太大的(de)問題。
