不合格電(dian)線(xian)電(dian)纜的(de)危害(hai)

電(dian)(dian)(dian)線電(dian)(dian)(dian)纜是用于傳(chuan)(chuan)輸電(dian)(dian)(dian)力(li)(li)、傳(chuan)(chuan)輸信息和(he)實現(xian)電(dian)(dian)(dian)磁能量(liang)轉(zhuan)換的(de)一大(da)(da)類(lei)電(dian)(dian)(dian)工(gong)產(chan)品。在抽查過(guo)程中，發現(xian)了大(da)(da)量(liang)的(de)不合格產(chan)品，這(zhe)些劣質產(chan)品給電(dian)(dian)(dian)力(li)(li)系統正常運行(xing)埋下諸多隱患。

1、標(biao)(biao)志(zhi)不(bu)合(he)格的電(dian)(dian)線電(dian)(dian)纜(lan)。標(biao)(biao)志(zhi)是電(dian)(dian)線電(dian)(dian)纜(lan)使用識別(bie)(bie)產品基本信息的主要途徑，根(gen)據(ju)標(biao)(biao)準規定標(biao)(biao)志(zhi)的主要內容是：產品型(xing)號(hao)(hao)、規格、標(biao)(biao)準號(hao)(hao)、廠名、產地等在一定的標(biao)(biao)示間(jian)距(ju)內，當(dang)標(biao)(biao)志(zhi)不(bu)合(he)格時，會造成施工人員識別(bie)(bie)錯(cuo)誤，嚴(yan)重時會引發電(dian)(dian)氣(qi)事故。

2、結構尺寸不(bu)合(he)格(ge)的(de)(de)電(dian)(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)(dian)纜(lan)。結構尺寸的(de)(de)主要問題是護(hu)(hu)套厚度(du)(du)，絕(jue)緣厚度(du)(du)，當電(dian)(dian)(dian)(dian)纜(lan)的(de)(de)護(hu)(hu)套和絕(jue)緣厚度(du)(du)不(bu)達標時，致使電(dian)(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)(dian)纜(lan)耐電(dian)(dian)(dian)(dian)氣(qi)強度(du)(du)會嚴重降低，導(dao)致電(dian)(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)(dian)纜(lan)的(de)(de)使用(yong)壽(shou)命縮短，嚴重時可導(dao)致電(dian)(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)(dian)纜(lan)被(bei)擊穿，絕(jue)緣（護(hu)(hu)套）層起不(bu)到正常保護(hu)(hu)作用(yong)，從而發生(sheng)電(dian)(dian)(dian)(dian)氣(qi)短路和火災等現象。

3、護(hu)套式絕(jue)緣老(lao)化前的(de)(de)抗張(zhang)強(qiang)度(du)、伸長(chang)(chang)(chang)率(lv)合格的(de)(de)電(dian)線電(dian)纜(lan)。絕(jue)緣護(hu)套老(lao)化前的(de)(de)抗張(zhang)強(qiang)度(du)、伸長(chang)(chang)(chang)率(lv)不(bu)合格直(zhi)接(jie)大大縮短(duan)電(dian)線電(dian)纜(lan)的(de)(de)工作用壽(shou)命，而且在(zai)施(shi)工或在(zai)長(chang)(chang)(chang)時間通電(dian)且溫(wen)度(du)較(jiao)高的(de)(de)環(huan)境中，極易出現絕(jue)緣體斷(duan)裂，致使帶電(dian)導體裸露(lu)，發生(sheng)能觸(chu)電(dian)式短(duan)路危(wei)險。其(qi)不(bu)合格的(de)(de)主要原(yuan)因是(shi)使用了再生(sheng)料(liao)生(sheng)產(chan)(chan)，以降(jiang)低(di)產(chan)(chan)品成(cheng)本，二是(shi)不(bu)具備生(sheng)產(chan)(chan)資(zi)格小型(xing)企(qi)業。

4、導(dao)(dao)(dao)體(ti)(ti)(ti)(ti)電(dian)(dian)(dian)(dian)(dian)阻(zu)不合(he)格的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)線(xian)。導(dao)(dao)(dao)體(ti)(ti)(ti)(ti)電(dian)(dian)(dian)(dian)(dian)阻(zu)主(zhu)要(yao)(yao)(yao)是(shi)考核電(dian)(dian)(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)的(de)(de)(de)導(dao)(dao)(dao)體(ti)(ti)(ti)(ti)材料以及截面(mian)是(shi)否符(fu)合(he)的(de)(de)(de)重要(yao)(yao)(yao)指標(biao)。當導(dao)(dao)(dao)體(ti)(ti)(ti)(ti)電(dian)(dian)(dian)(dian)(dian)阻(zu)超標(biao)時(shi)，就增大(da)了(le)(le)電(dian)(dian)(dian)(dian)(dian)流(liu)在(zai)(zai)線(xian)路上通(tong)過時(shi)的(de)(de)(de)損耗，加劇了(le)(le)電(dian)(dian)(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)的(de)(de)(de)發熱。導(dao)(dao)(dao)體(ti)(ti)(ti)(ti)電(dian)(dian)(dian)(dian)(dian)阻(zu)不合(he)格的(de)(de)(de)原因，主(zhu)要(yao)(yao)(yao)進企業為了(le)(le)降低成(cheng)本(ben)，將占(zhan)原材料成(cheng)本(ben)80%的(de)(de)(de)銅(tong)材縮水(shui)，要(yao)(yao)(yao)么(me)降低導(dao)(dao)(dao)體(ti)(ti)(ti)(ti)的(de)(de)(de)截面(mian)積，要(yao)(yao)(yao)么(me)使用含雜質過高的(de)(de)(de)再生銅(tong)，這樣致使電(dian)(dian)(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)的(de)(de)(de)導(dao)(dao)(dao)體(ti)(ti)(ti)(ti)電(dian)(dian)(dian)(dian)(dian)阻(zu)嚴重超標(biao)，在(zai)(zai)使用過程中除易(yi)引發火災，還會加速包覆在(zai)(zai)電(dian)(dian)(dian)(dian)(dian)線(xian)外的(de)(de)(de)絕緣層的(de)(de)(de)老化。

在購買電線電纜(lan)的(de)過程中，消費者應注意(yi)以下幾個事(shi)

第一(yi)、要觀察(cha)電線的外觀。合格(ge)產品的絕(jue)緣(yuan)（護套）層柔軟(ruan)、有韌(ren)性和伸(shen)縮性、表面層緊密、光滑、無粗糙感。如(ru)果包(bao)裹電線的塑料很容易被剝去，則存(cun)在塑料強度不夠的問(wen)題(ti)。

第(di)二(er)、要看電(dian)線的(de)截面。合格產品的(de)銅(tong)芯或鋁(lv)芯表(biao)面應該具(ju)有金屬光(guang)澤，表(biao)面發(fa)黑的(de)銅(tong)或表(biao)面發(fa)白的(de)鋁(lv)說明已被(bei)氧化。

第三、在購(gou)買電線時應注(zhu)意查看質量合格證書。如果電線的質量合格，那(nei)么(me)其(qi)電線質量應該也受過檢驗，不會有太大的問(wen)題。
