不合格電(dian)線電(dian)纜的危害

電(dian)(dian)線電(dian)(dian)纜是(shi)用于傳(chuan)輸(shu)電(dian)(dian)力(li)、傳(chuan)輸(shu)信息和實現(xian)電(dian)(dian)磁能量轉換(huan)的一大(da)類電(dian)(dian)工產(chan)品(pin)。在抽查過程(cheng)中，發(fa)現(xian)了大(da)量的不(bu)合(he)格(ge)產(chan)品(pin)，這些(xie)劣質產(chan)品(pin)給電(dian)(dian)力(li)系統正常運(yun)行埋下諸多隱患(huan)。

1、標(biao)志不合(he)格(ge)的電線(xian)電纜。標(biao)志是電線(xian)電纜使用識別(bie)產品基本信息的主要途徑，根據標(biao)準規定標(biao)志的主要內(nei)容是：產品型號、規格(ge)、標(biao)準號、廠名、產地等(deng)在一定的標(biao)示間距內(nei)，當標(biao)志不合(he)格(ge)時，會(hui)造成施工人(ren)員識別(bie)錯誤，嚴重時會(hui)引(yin)發電氣事故。

2、結構尺(chi)寸(cun)不(bu)合(he)格的(de)(de)電(dian)(dian)(dian)線(xian)(xian)電(dian)(dian)(dian)纜(lan)(lan)。結構尺(chi)寸(cun)的(de)(de)主要問(wen)題是護(hu)套厚度，絕(jue)緣厚度，當電(dian)(dian)(dian)纜(lan)(lan)的(de)(de)護(hu)套和絕(jue)緣厚度不(bu)達標(biao)時，致(zhi)使電(dian)(dian)(dian)線(xian)(xian)電(dian)(dian)(dian)纜(lan)(lan)耐(nai)電(dian)(dian)(dian)氣(qi)(qi)強(qiang)度會嚴(yan)重降低，導(dao)致(zhi)電(dian)(dian)(dian)線(xian)(xian)電(dian)(dian)(dian)纜(lan)(lan)的(de)(de)使用壽命縮短，嚴(yan)重時可導(dao)致(zhi)電(dian)(dian)(dian)線(xian)(xian)電(dian)(dian)(dian)纜(lan)(lan)被擊穿(chuan)，絕(jue)緣（護(hu)套）層起不(bu)到正常保護(hu)作用，從而發生電(dian)(dian)(dian)氣(qi)(qi)短路和火災(zai)等現象。

3、護(hu)套(tao)式(shi)絕緣老(lao)化前的(de)(de)抗(kang)張(zhang)強度(du)、伸長率(lv)合格(ge)的(de)(de)電(dian)(dian)(dian)線電(dian)(dian)(dian)纜。絕緣護(hu)套(tao)老(lao)化前的(de)(de)抗(kang)張(zhang)強度(du)、伸長率(lv)不(bu)合格(ge)直接(jie)大大縮短(duan)電(dian)(dian)(dian)線電(dian)(dian)(dian)纜的(de)(de)工(gong)(gong)作(zuo)用壽(shou)命，而且在施工(gong)(gong)或在長時間通電(dian)(dian)(dian)且溫度(du)較高的(de)(de)環(huan)境中，極易出現絕緣體斷裂，致使(shi)帶電(dian)(dian)(dian)導(dao)體裸(luo)露，發生能觸電(dian)(dian)(dian)式(shi)短(duan)路危(wei)險。其不(bu)合格(ge)的(de)(de)主要(yao)原因是使(shi)用了再生料(liao)生產，以降(jiang)低產品成本，二(er)是不(bu)具備生產資格(ge)小型企業。

4、導(dao)(dao)體(ti)(ti)電(dian)(dian)阻(zu)不(bu)合格(ge)的(de)(de)(de)電(dian)(dian)線(xian)(xian)(xian)。導(dao)(dao)體(ti)(ti)電(dian)(dian)阻(zu)主要是考核電(dian)(dian)線(xian)(xian)(xian)電(dian)(dian)纜的(de)(de)(de)導(dao)(dao)體(ti)(ti)材(cai)料以(yi)及截面是否符合的(de)(de)(de)重(zhong)要指標(biao)。當導(dao)(dao)體(ti)(ti)電(dian)(dian)阻(zu)超標(biao)時(shi)，就增大了電(dian)(dian)流在線(xian)(xian)(xian)路上通過(guo)時(shi)的(de)(de)(de)損耗(hao)，加劇(ju)了電(dian)(dian)線(xian)(xian)(xian)電(dian)(dian)纜的(de)(de)(de)發熱。導(dao)(dao)體(ti)(ti)電(dian)(dian)阻(zu)不(bu)合格(ge)的(de)(de)(de)原因，主要進企業為(wei)了降低成(cheng)本，將占(zhan)原材(cai)料成(cheng)本80%的(de)(de)(de)銅(tong)材(cai)縮水(shui)，要么降低導(dao)(dao)體(ti)(ti)的(de)(de)(de)截面積，要么使(shi)用含雜(za)質過(guo)高的(de)(de)(de)再生銅(tong)，這樣致使(shi)電(dian)(dian)線(xian)(xian)(xian)電(dian)(dian)纜的(de)(de)(de)導(dao)(dao)體(ti)(ti)電(dian)(dian)阻(zu)嚴重(zhong)超標(biao)，在使(shi)用過(guo)程(cheng)中除易引發火(huo)災，還會(hui)加速包覆(fu)在電(dian)(dian)線(xian)(xian)(xian)外的(de)(de)(de)絕緣層的(de)(de)(de)老化(hua)。

在購買電線電纜的過(guo)程中(zhong)，消費者應(ying)注(zhu)意以(yi)下幾個事(shi)

第(di)一、要觀(guan)察電線(xian)的(de)外(wai)觀(guan)。合格產品的(de)絕緣（護套(tao)）層柔軟(ruan)、有韌性和伸(shen)縮(suo)性、表面(mian)層緊密、光滑(hua)、無(wu)粗糙(cao)感。如果包裹(guo)電線(xian)的(de)塑料(liao)很容易被剝去，則(ze)存在塑料(liao)強度不夠(gou)的(de)問題(ti)。

第二(er)、要看電線的(de)截(jie)面(mian)(mian)(mian)。合格(ge)產品的(de)銅(tong)芯或鋁(lv)芯表(biao)面(mian)(mian)(mian)應該具(ju)有金屬(shu)光澤，表(biao)面(mian)(mian)(mian)發(fa)黑(hei)的(de)銅(tong)或表(biao)面(mian)(mian)(mian)發(fa)白的(de)鋁(lv)說明(ming)已(yi)被氧化。

第三、在購(gou)買電線時應(ying)注意查看質量(liang)合格(ge)證書(shu)。如果電線的質量(liang)合格(ge)，那(nei)么其電線質量(liang)應(ying)該也受過檢驗，不會有太大的問題。
