不合格電(dian)線電(dian)纜的危害

電(dian)(dian)(dian)線電(dian)(dian)(dian)纜是用于傳(chuan)輸(shu)電(dian)(dian)(dian)力(li)、傳(chuan)輸(shu)信息和實現(xian)電(dian)(dian)(dian)磁能(neng)量(liang)轉換的一大(da)類(lei)電(dian)(dian)(dian)工產(chan)品(pin)。在抽查過程中，發現(xian)了(le)大(da)量(liang)的不合格產(chan)品(pin)，這些劣質產(chan)品(pin)給電(dian)(dian)(dian)力(li)系統正常運行埋下(xia)諸多隱患。

1、標(biao)(biao)志不(bu)合格的(de)電(dian)(dian)線(xian)(xian)電(dian)(dian)纜。標(biao)(biao)志是電(dian)(dian)線(xian)(xian)電(dian)(dian)纜使用識別產品基本(ben)信息的(de)主要(yao)途徑(jing)，根據標(biao)(biao)準規(gui)定標(biao)(biao)志的(de)主要(yao)內(nei)容是：產品型(xing)號(hao)(hao)、規(gui)格、標(biao)(biao)準號(hao)(hao)、廠名(ming)、產地等在一定的(de)標(biao)(biao)示(shi)間距內(nei)，當標(biao)(biao)志不(bu)合格時，會造(zao)成(cheng)施(shi)工(gong)人(ren)員識別錯(cuo)誤，嚴(yan)重時會引發電(dian)(dian)氣事故。

2、結構尺寸(cun)不合格的電(dian)(dian)線(xian)電(dian)(dian)纜(lan)。結構尺寸(cun)的主要問題是護(hu)套厚度，絕緣(yuan)厚度，當電(dian)(dian)纜(lan)的護(hu)套和絕緣(yuan)厚度不達(da)標時，致使電(dian)(dian)線(xian)電(dian)(dian)纜(lan)耐電(dian)(dian)氣(qi)(qi)強度會嚴重降低，導致電(dian)(dian)線(xian)電(dian)(dian)纜(lan)的使用(yong)壽命縮短(duan)，嚴重時可導致電(dian)(dian)線(xian)電(dian)(dian)纜(lan)被擊穿(chuan)，絕緣(yuan)（護(hu)套）層起不到正(zheng)常(chang)保護(hu)作用(yong)，從而(er)發(fa)生電(dian)(dian)氣(qi)(qi)短(duan)路和火(huo)災等現象。

3、護套式絕緣(yuan)老化前的(de)(de)抗(kang)張強(qiang)度、伸(shen)長(chang)率(lv)合格(ge)的(de)(de)電線(xian)電纜(lan)。絕緣(yuan)護套老化前的(de)(de)抗(kang)張強(qiang)度、伸(shen)長(chang)率(lv)不合格(ge)直接大大縮短(duan)(duan)電線(xian)電纜(lan)的(de)(de)工作用(yong)壽命，而且(qie)在施工或(huo)在長(chang)時間(jian)通電且(qie)溫度較高的(de)(de)環境中，極易出現絕緣(yuan)體(ti)斷裂(lie)，致使帶電導(dao)體(ti)裸露，發(fa)生(sheng)(sheng)能(neng)觸電式短(duan)(duan)路危(wei)險(xian)。其不合格(ge)的(de)(de)主要原(yuan)因是使用(yong)了再生(sheng)(sheng)料生(sheng)(sheng)產(chan)，以降低產(chan)品成本，二是不具備生(sheng)(sheng)產(chan)資格(ge)小型企業。

4、導(dao)體(ti)電(dian)阻(zu)不合(he)格的(de)(de)電(dian)線。導(dao)體(ti)電(dian)阻(zu)主要(yao)(yao)是(shi)考核電(dian)線電(dian)纜的(de)(de)導(dao)體(ti)材(cai)料以及截(jie)面是(shi)否符合(he)的(de)(de)重要(yao)(yao)指(zhi)標。當導(dao)體(ti)電(dian)阻(zu)超(chao)標時(shi)，就增大了電(dian)流在線路上(shang)通(tong)過(guo)時(shi)的(de)(de)損耗，加(jia)劇(ju)了電(dian)線電(dian)纜的(de)(de)發熱。導(dao)體(ti)電(dian)阻(zu)不合(he)格的(de)(de)原(yuan)因，主要(yao)(yao)進企業為了降(jiang)低成(cheng)(cheng)本，將占原(yuan)材(cai)料成(cheng)(cheng)本80%的(de)(de)銅材(cai)縮水，要(yao)(yao)么(me)降(jiang)低導(dao)體(ti)的(de)(de)截(jie)面積，要(yao)(yao)么(me)使(shi)用含雜質過(guo)高的(de)(de)再生(sheng)銅，這樣致使(shi)電(dian)線電(dian)纜的(de)(de)導(dao)體(ti)電(dian)阻(zu)嚴重超(chao)標，在使(shi)用過(guo)程中除易引發火災，還會加(jia)速包(bao)覆在電(dian)線外的(de)(de)絕緣(yuan)層的(de)(de)老化。

在購(gou)買電線(xian)電纜(lan)的過程中(zhong)，消費者應(ying)注意以下(xia)幾個事

第(di)一、要觀察電線的外觀。合格產品的絕緣（護套(tao)）層柔軟、有韌性(xing)和伸縮(suo)性(xing)、表面層緊密、光滑、無(wu)粗糙感。如果包裹(guo)電線的塑料很(hen)容易被剝去，則存在塑料強度不夠的問題。

第(di)二、要看電(dian)線的(de)截面(mian)。合格產品(pin)的(de)銅芯(xin)或鋁芯(xin)表面(mian)應(ying)該(gai)具有金屬光澤，表面(mian)發(fa)黑的(de)銅或表面(mian)發(fa)白(bai)的(de)鋁說明已被氧化(hua)。

第三、在購買電線時(shi)應注意查看質(zhi)量合(he)(he)格證書。如果電線的質(zhi)量合(he)(he)格，那么其(qi)電線質(zhi)量應該也受過檢驗，不會有太大的問題。
