不合格電(dian)(dian)線電(dian)(dian)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)信息和實現電(dian)(dian)磁能(neng)量轉換(huan)的一大(da)(da)類電(dian)(dian)工產(chan)品。在抽(chou)查過程(cheng)中(zhong)，發(fa)現了大(da)(da)量的不合(he)格產(chan)品，這些劣質產(chan)品給(gei)電(dian)(dian)力系統正常(chang)運行(xing)埋(mai)下諸多(duo)隱患(huan)。

1、標(biao)志(zhi)不合格(ge)的電(dian)線電(dian)纜。標(biao)志(zhi)是電(dian)線電(dian)纜使用(yong)識別(bie)產(chan)品基本(ben)信息的主(zhu)(zhu)要途徑，根據標(biao)準規定(ding)標(biao)志(zhi)的主(zhu)(zhu)要內容(rong)是：產(chan)品型(xing)號、規格(ge)、標(biao)準號、廠名、產(chan)地等在一定(ding)的標(biao)示間距內，當(dang)標(biao)志(zhi)不合格(ge)時(shi)，會造成施工(gong)人員識別(bie)錯誤，嚴重時(shi)會引發電(dian)氣事故。

2、結(jie)構尺寸(cun)不(bu)(bu)合格的(de)(de)電(dian)(dian)(dian)線(xian)(xian)電(dian)(dian)(dian)纜(lan)(lan)。結(jie)構尺寸(cun)的(de)(de)主要問題是護(hu)套(tao)厚(hou)(hou)度(du)，絕(jue)緣厚(hou)(hou)度(du)，當電(dian)(dian)(dian)纜(lan)(lan)的(de)(de)護(hu)套(tao)和絕(jue)緣厚(hou)(hou)度(du)不(bu)(bu)達標時，致(zhi)(zhi)(zhi)使電(dian)(dian)(dian)線(xian)(xian)電(dian)(dian)(dian)纜(lan)(lan)耐(nai)電(dian)(dian)(dian)氣(qi)強度(du)會嚴(yan)重(zhong)降(jiang)低，導(dao)(dao)致(zhi)(zhi)(zhi)電(dian)(dian)(dian)線(xian)(xian)電(dian)(dian)(dian)纜(lan)(lan)的(de)(de)使用壽命縮短(duan)，嚴(yan)重(zhong)時可(ke)導(dao)(dao)致(zhi)(zhi)(zhi)電(dian)(dian)(dian)線(xian)(xian)電(dian)(dian)(dian)纜(lan)(lan)被(bei)擊穿，絕(jue)緣（護(hu)套(tao)）層起不(bu)(bu)到正常保護(hu)作用，從而(er)發生(sheng)電(dian)(dian)(dian)氣(qi)短(duan)路(lu)和火災等現(xian)象。

3、護(hu)套式(shi)絕(jue)緣老(lao)化(hua)前(qian)的(de)抗張(zhang)強度、伸長(chang)率(lv)合格(ge)的(de)電(dian)線電(dian)纜。絕(jue)緣護(hu)套老(lao)化(hua)前(qian)的(de)抗張(zhang)強度、伸長(chang)率(lv)不合格(ge)直(zhi)接(jie)大(da)大(da)縮(suo)短電(dian)線電(dian)纜的(de)工作用(yong)(yong)壽命，而且在(zai)施工或在(zai)長(chang)時間通電(dian)且溫度較高的(de)環(huan)境(jing)中，極(ji)易出現(xian)絕(jue)緣體斷裂，致使帶電(dian)導體裸露，發(fa)生(sheng)能觸電(dian)式(shi)短路危(wei)險。其不合格(ge)的(de)主要原因(yin)是使用(yong)(yong)了(le)再生(sheng)料生(sheng)產(chan)，以(yi)降低產(chan)品(pin)成本，二是不具備生(sheng)產(chan)資格(ge)小型企業。

4、導(dao)體(ti)(ti)電(dian)(dian)阻(zu)不(bu)合格的(de)電(dian)(dian)線(xian)(xian)。導(dao)體(ti)(ti)電(dian)(dian)阻(zu)主要(yao)是(shi)考核電(dian)(dian)線(xian)(xian)電(dian)(dian)纜的(de)導(dao)體(ti)(ti)材(cai)料以(yi)及截(jie)面是(shi)否符合的(de)重(zhong)要(yao)指標。當導(dao)體(ti)(ti)電(dian)(dian)阻(zu)超標時(shi)，就增大了(le)(le)電(dian)(dian)流在(zai)線(xian)(xian)路上通(tong)過(guo)時(shi)的(de)損耗(hao)，加(jia)劇了(le)(le)電(dian)(dian)線(xian)(xian)電(dian)(dian)纜的(de)發熱(re)。導(dao)體(ti)(ti)電(dian)(dian)阻(zu)不(bu)合格的(de)原因，主要(yao)進企業為(wei)了(le)(le)降低成本(ben)(ben)，將占原材(cai)料成本(ben)(ben)80%的(de)銅(tong)材(cai)縮水，要(yao)么降低導(dao)體(ti)(ti)的(de)截(jie)面積(ji)，要(yao)么使(shi)用含雜(za)質過(guo)高的(de)再生銅(tong)，這樣致(zhi)使(shi)電(dian)(dian)線(xian)(xian)電(dian)(dian)纜的(de)導(dao)體(ti)(ti)電(dian)(dian)阻(zu)嚴重(zhong)超標，在(zai)使(shi)用過(guo)程中除易引發火災，還會加(jia)速包覆在(zai)電(dian)(dian)線(xian)(xian)外的(de)絕緣層的(de)老化(hua)。

在(zai)購(gou)買(mai)電(dian)線(xian)電(dian)纜(lan)的過程中(zhong)，消費者應(ying)注意(yi)以下幾個事(shi)

第一、要(yao)觀察(cha)電(dian)(dian)線的(de)外(wai)觀。合(he)格產品(pin)的(de)絕緣(yuan)（護套）層柔軟、有(you)韌性和伸縮性、表面(mian)層緊密、光滑、無粗糙感。如果包裹電(dian)(dian)線的(de)塑料(liao)很容易被剝去，則存在(zai)塑料(liao)強(qiang)度(du)不夠的(de)問題。

第(di)二、要(yao)看電線的(de)(de)截面(mian)。合格產品的(de)(de)銅芯(xin)或(huo)鋁芯(xin)表(biao)面(mian)應該具有金屬光澤，表(biao)面(mian)發黑的(de)(de)銅或(huo)表(biao)面(mian)發白(bai)的(de)(de)鋁說明已(yi)被氧(yang)化。

第三、在購(gou)買(mai)電(dian)線(xian)時應(ying)注意查看質(zhi)量合(he)格(ge)證書(shu)。如果電(dian)線(xian)的(de)質(zhi)量合(he)格(ge)，那么其電(dian)線(xian)質(zhi)量應(ying)該(gai)也受過(guo)檢驗，不會有太(tai)大的(de)問題。
