不(bu)合格(ge)電(dian)線(xian)電(dian)纜的危害(hai)

電(dian)(dian)線電(dian)(dian)纜是用于傳(chuan)輸電(dian)(dian)力、傳(chuan)輸信息和實現電(dian)(dian)磁能(neng)量轉換的(de)一(yi)大類電(dian)(dian)工產(chan)品(pin)(pin)。在抽(chou)查過(guo)程中(zhong)，發現了大量的(de)不合格產(chan)品(pin)(pin)，這些劣(lie)質產(chan)品(pin)(pin)給電(dian)(dian)力系統正常(chang)運行埋下諸多隱患。

1、標(biao)志不(bu)合(he)格的(de)電(dian)(dian)線(xian)電(dian)(dian)纜。標(biao)志是電(dian)(dian)線(xian)電(dian)(dian)纜使(shi)用識(shi)別產(chan)品基本信息的(de)主要(yao)途徑，根據標(biao)準規定標(biao)志的(de)主要(yao)內容是：產(chan)品型號(hao)、規格、標(biao)準號(hao)、廠(chang)名(ming)、產(chan)地等在一定的(de)標(biao)示間距內，當標(biao)志不(bu)合(he)格時，會造成(cheng)施工人員識(shi)別錯誤，嚴重時會引發電(dian)(dian)氣事故。

2、結構(gou)尺寸(cun)不合格的電(dian)(dian)(dian)(dian)(dian)線(xian)(xian)(xian)電(dian)(dian)(dian)(dian)(dian)纜(lan)。結構(gou)尺寸(cun)的主要(yao)問題是(shi)護(hu)套厚度(du)，絕緣厚度(du)，當電(dian)(dian)(dian)(dian)(dian)纜(lan)的護(hu)套和(he)絕緣厚度(du)不達標時，致(zhi)使電(dian)(dian)(dian)(dian)(dian)線(xian)(xian)(xian)電(dian)(dian)(dian)(dian)(dian)纜(lan)耐(nai)電(dian)(dian)(dian)(dian)(dian)氣強(qiang)度(du)會(hui)嚴重(zhong)降低(di)，導(dao)致(zhi)電(dian)(dian)(dian)(dian)(dian)線(xian)(xian)(xian)電(dian)(dian)(dian)(dian)(dian)纜(lan)的使用(yong)(yong)壽命(ming)縮(suo)短，嚴重(zhong)時可導(dao)致(zhi)電(dian)(dian)(dian)(dian)(dian)線(xian)(xian)(xian)電(dian)(dian)(dian)(dian)(dian)纜(lan)被擊穿(chuan)，絕緣（護(hu)套）層起不到正常保護(hu)作用(yong)(yong)，從(cong)而發(fa)生電(dian)(dian)(dian)(dian)(dian)氣短路和(he)火災等現象。

3、護套式絕(jue)(jue)緣老化前的(de)抗(kang)張強度(du)(du)、伸長率合格的(de)電(dian)線電(dian)纜。絕(jue)(jue)緣護套老化前的(de)抗(kang)張強度(du)(du)、伸長率不(bu)合格直接大大縮短電(dian)線電(dian)纜的(de)工(gong)作用壽命，而(er)且在(zai)施工(gong)或在(zai)長時(shi)間通電(dian)且溫度(du)(du)較高的(de)環境(jing)中，極易(yi)出(chu)現絕(jue)(jue)緣體斷裂，致使帶電(dian)導體裸露，發生(sheng)能觸(chu)電(dian)式短路危險。其不(bu)合格的(de)主(zhu)要原因是(shi)使用了再生(sheng)料生(sheng)產(chan)，以(yi)降低(di)產(chan)品成本，二是(shi)不(bu)具備生(sheng)產(chan)資格小型(xing)企業(ye)。

4、導(dao)(dao)(dao)體(ti)(ti)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)阻(zu)不合(he)格的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)線。導(dao)(dao)(dao)體(ti)(ti)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)阻(zu)主要(yao)是(shi)考(kao)核(he)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)線電(dian)(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)的(de)(de)(de)導(dao)(dao)(dao)體(ti)(ti)材料(liao)以(yi)及截面是(shi)否符(fu)合(he)的(de)(de)(de)重(zhong)要(yao)指標。當導(dao)(dao)(dao)體(ti)(ti)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)阻(zu)超標時(shi)，就增大了(le)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流在線路上(shang)通過(guo)時(shi)的(de)(de)(de)損耗，加(jia)劇了(le)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)線電(dian)(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)的(de)(de)(de)發熱(re)。導(dao)(dao)(dao)體(ti)(ti)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)阻(zu)不合(he)格的(de)(de)(de)原(yuan)因(yin)，主要(yao)進企業(ye)為了(le)降低成(cheng)本(ben)，將占原(yuan)材料(liao)成(cheng)本(ben)80%的(de)(de)(de)銅材縮(suo)水，要(yao)么降低導(dao)(dao)(dao)體(ti)(ti)的(de)(de)(de)截面積(ji)，要(yao)么使用含(han)雜質過(guo)高的(de)(de)(de)再生銅，這樣(yang)致(zhi)使電(dian)(dian)(dian)(dian)(dian)(dian)(dian)線電(dian)(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)的(de)(de)(de)導(dao)(dao)(dao)體(ti)(ti)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)阻(zu)嚴(yan)重(zhong)超標，在使用過(guo)程中除易引(yin)發火災(zai)，還會(hui)加(jia)速(su)包覆在電(dian)(dian)(dian)(dian)(dian)(dian)(dian)線外的(de)(de)(de)絕緣(yuan)層的(de)(de)(de)老(lao)化(hua)。

在購(gou)買電(dian)線電(dian)纜的過(guo)程中，消費者(zhe)應注(zhu)意以下幾個(ge)事

第一(yi)、要觀察電線(xian)的(de)外觀。合格產品的(de)絕緣（護套）層(ceng)柔軟、有韌(ren)性和伸縮性、表面(mian)層(ceng)緊密、光滑(hua)、無粗糙感(gan)。如果包裹電線(xian)的(de)塑料很(hen)容易(yi)被剝去，則存在(zai)塑料強度不夠(gou)的(de)問(wen)題(ti)。

第二、要看電線的(de)截面(mian)。合格產(chan)品(pin)的(de)銅(tong)芯(xin)(xin)或(huo)鋁芯(xin)(xin)表面(mian)應該具有金屬光澤，表面(mian)發(fa)黑的(de)銅(tong)或(huo)表面(mian)發(fa)白(bai)的(de)鋁說(shuo)明已(yi)被氧(yang)化。

第三、在(zai)購(gou)買電線(xian)時(shi)應注意(yi)查看質量合格(ge)證書。如果電線(xian)的質量合格(ge)，那么其(qi)電線(xian)質量應該也(ye)受過檢驗，不會(hui)有太大的問(wen)題。
