不(bu)合格電線(xian)電纜(lan)的危害

電(dian)(dian)線電(dian)(dian)纜是(shi)用(yong)于傳(chuan)輸(shu)(shu)電(dian)(dian)力(li)、傳(chuan)輸(shu)(shu)信息(xi)和(he)實現(xian)電(dian)(dian)磁能量(liang)轉換(huan)的一大類電(dian)(dian)工產(chan)品(pin)。在抽查過程(cheng)中(zhong)，發(fa)現(xian)了大量(liang)的不合格產(chan)品(pin)，這些劣(lie)質產(chan)品(pin)給電(dian)(dian)力(li)系統正常運(yun)行埋(mai)下諸多隱患。

1、標(biao)(biao)志(zhi)(zhi)不合格的(de)(de)電線電纜。標(biao)(biao)志(zhi)(zhi)是電線電纜使用識別(bie)產品基本信(xin)息(xi)的(de)(de)主(zhu)要途徑，根據標(biao)(biao)準(zhun)規定標(biao)(biao)志(zhi)(zhi)的(de)(de)主(zhu)要內容(rong)是：產品型號、規格、標(biao)(biao)準(zhun)號、廠名、產地等(deng)在一(yi)定的(de)(de)標(biao)(biao)示間距內，當標(biao)(biao)志(zhi)(zhi)不合格時，會造成施(shi)工人員識別(bie)錯誤，嚴(yan)重時會引(yin)發電氣事故(gu)。

2、結構尺寸(cun)不(bu)合格的(de)(de)電(dian)線(xian)電(dian)纜。結構尺寸(cun)的(de)(de)主要問題是護套厚度(du)，絕(jue)緣厚度(du)，當電(dian)纜的(de)(de)護套和(he)絕(jue)緣厚度(du)不(bu)達標(biao)時，致使(shi)(shi)電(dian)線(xian)電(dian)纜耐(nai)電(dian)氣強(qiang)度(du)會(hui)嚴(yan)重降低，導致電(dian)線(xian)電(dian)纜的(de)(de)使(shi)(shi)用壽命縮短，嚴(yan)重時可導致電(dian)線(xian)電(dian)纜被擊穿，絕(jue)緣（護套）層(ceng)起不(bu)到正常保護作(zuo)用，從而發生電(dian)氣短路和(he)火(huo)災等(deng)現象。

3、護套式(shi)絕緣老(lao)化前的(de)(de)抗張強度(du)(du)、伸(shen)長率(lv)合格的(de)(de)電(dian)(dian)線(xian)電(dian)(dian)纜(lan)。絕緣護套老(lao)化前的(de)(de)抗張強度(du)(du)、伸(shen)長率(lv)不合格直接大(da)大(da)縮短電(dian)(dian)線(xian)電(dian)(dian)纜(lan)的(de)(de)工作用壽命，而且在(zai)施工或(huo)在(zai)長時間通電(dian)(dian)且溫度(du)(du)較高的(de)(de)環境中，極易出(chu)現絕緣體(ti)斷裂，致使帶(dai)電(dian)(dian)導體(ti)裸露，發生(sheng)能(neng)觸電(dian)(dian)式(shi)短路危險。其不合格的(de)(de)主要原因是(shi)使用了再生(sheng)料生(sheng)產，以降低產品成(cheng)本，二(er)是(shi)不具備生(sheng)產資格小型企業。

4、導(dao)體(ti)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)阻(zu)不合(he)格(ge)的(de)(de)(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)線(xian)(xian)(xian)。導(dao)體(ti)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)阻(zu)主(zhu)要(yao)是考核電(dian)(dian)(dian)(dian)(dian)(dian)(dian)線(xian)(xian)(xian)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)的(de)(de)(de)(de)(de)(de)導(dao)體(ti)材料以(yi)及截(jie)面(mian)(mian)是否(fou)符(fu)合(he)的(de)(de)(de)(de)(de)(de)重(zhong)要(yao)指標。當導(dao)體(ti)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)阻(zu)超(chao)標時，就增大了電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流在(zai)線(xian)(xian)(xian)路(lu)上通過時的(de)(de)(de)(de)(de)(de)損(sun)耗(hao)，加劇了電(dian)(dian)(dian)(dian)(dian)(dian)(dian)線(xian)(xian)(xian)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)的(de)(de)(de)(de)(de)(de)發(fa)熱。導(dao)體(ti)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)阻(zu)不合(he)格(ge)的(de)(de)(de)(de)(de)(de)原因，主(zhu)要(yao)進企業為(wei)了降(jiang)低(di)成本，將占(zhan)原材料成本80%的(de)(de)(de)(de)(de)(de)銅(tong)材縮水，要(yao)么(me)降(jiang)低(di)導(dao)體(ti)的(de)(de)(de)(de)(de)(de)截(jie)面(mian)(mian)積，要(yao)么(me)使用(yong)含(han)雜質過高(gao)的(de)(de)(de)(de)(de)(de)再生銅(tong)，這樣致使電(dian)(dian)(dian)(dian)(dian)(dian)(dian)線(xian)(xian)(xian)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)的(de)(de)(de)(de)(de)(de)導(dao)體(ti)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)阻(zu)嚴重(zhong)超(chao)標，在(zai)使用(yong)過程中除易(yi)引發(fa)火災，還(huan)會加速包覆(fu)在(zai)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)線(xian)(xian)(xian)外的(de)(de)(de)(de)(de)(de)絕緣層的(de)(de)(de)(de)(de)(de)老化(hua)。

在購買電(dian)線電(dian)纜的過程中，消費者應注意以下(xia)幾個事

第一、要觀察電(dian)線(xian)的外觀。合(he)格產品的絕緣(yuan)（護套）層柔軟(ruan)、有韌性和伸(shen)縮性、表面層緊密、光(guang)滑、無粗(cu)糙(cao)感(gan)。如果包裹電(dian)線(xian)的塑(su)料(liao)很容易被剝去，則存在塑(su)料(liao)強度(du)不夠(gou)的問題。

第二、要看電線的(de)(de)截面。合格產品的(de)(de)銅(tong)芯或鋁(lv)(lv)芯表面應該(gai)具有金屬光澤，表面發黑的(de)(de)銅(tong)或表面發白(bai)的(de)(de)鋁(lv)(lv)說明已被氧化(hua)。

第三(san)、在購買電(dian)(dian)線時(shi)應注意(yi)查看質量(liang)合格證書。如(ru)果電(dian)(dian)線的質量(liang)合格，那么其電(dian)(dian)線質量(liang)應該也受過(guo)檢驗，不會有(you)太大的問題。
