不合格電(dian)線電(dian)纜的危害

電(dian)(dian)線電(dian)(dian)纜是(shi)用于傳(chuan)輸電(dian)(dian)力(li)、傳(chuan)輸信息(xi)和實現電(dian)(dian)磁(ci)能量轉換的(de)一大(da)類電(dian)(dian)工產(chan)品(pin)(pin)。在抽查過程中(zhong)，發現了大(da)量的(de)不(bu)合(he)格產(chan)品(pin)(pin)，這些劣質產(chan)品(pin)(pin)給(gei)電(dian)(dian)力(li)系統正常運(yun)行埋下諸(zhu)多隱(yin)患。

1、標(biao)(biao)(biao)志(zhi)(zhi)不合(he)(he)格(ge)的(de)電(dian)線電(dian)纜(lan)。標(biao)(biao)(biao)志(zhi)(zhi)是電(dian)線電(dian)纜(lan)使用識(shi)別產(chan)品(pin)基本信息(xi)的(de)主要(yao)途徑，根據標(biao)(biao)(biao)準規定(ding)(ding)標(biao)(biao)(biao)志(zhi)(zhi)的(de)主要(yao)內容是：產(chan)品(pin)型號、規格(ge)、標(biao)(biao)(biao)準號、廠名、產(chan)地等在(zai)一(yi)定(ding)(ding)的(de)標(biao)(biao)(biao)示間距內，當(dang)標(biao)(biao)(biao)志(zhi)(zhi)不合(he)(he)格(ge)時，會造成施工人員識(shi)別錯誤，嚴重時會引發電(dian)氣(qi)事故。

2、結構尺寸不合格(ge)的(de)(de)電(dian)(dian)(dian)線(xian)(xian)(xian)電(dian)(dian)(dian)纜(lan)(lan)。結構尺寸的(de)(de)主(zhu)要問題是護(hu)套(tao)厚(hou)度，絕(jue)緣厚(hou)度，當電(dian)(dian)(dian)纜(lan)(lan)的(de)(de)護(hu)套(tao)和絕(jue)緣厚(hou)度不達標時，致使電(dian)(dian)(dian)線(xian)(xian)(xian)電(dian)(dian)(dian)纜(lan)(lan)耐(nai)電(dian)(dian)(dian)氣強度會嚴重降低，導致電(dian)(dian)(dian)線(xian)(xian)(xian)電(dian)(dian)(dian)纜(lan)(lan)的(de)(de)使用壽命縮短，嚴重時可導致電(dian)(dian)(dian)線(xian)(xian)(xian)電(dian)(dian)(dian)纜(lan)(lan)被擊穿，絕(jue)緣（護(hu)套(tao)）層起不到正常保護(hu)作用，從而發生電(dian)(dian)(dian)氣短路和火災(zai)等現象(xiang)。

3、護(hu)套式(shi)絕緣(yuan)老(lao)(lao)化前的抗(kang)張強度、伸(shen)長率(lv)合格(ge)的電線(xian)電纜(lan)(lan)。絕緣(yuan)護(hu)套老(lao)(lao)化前的抗(kang)張強度、伸(shen)長率(lv)不(bu)合格(ge)直接大大縮短電線(xian)電纜(lan)(lan)的工(gong)作用壽(shou)命(ming)，而且(qie)在施(shi)工(gong)或(huo)在長時間通電且(qie)溫(wen)度較高的環(huan)境中，極易出現(xian)絕緣(yuan)體斷裂，致使(shi)帶電導體裸露，發生(sheng)(sheng)(sheng)能(neng)觸電式(shi)短路危險(xian)。其(qi)不(bu)合格(ge)的主要原因是(shi)使(shi)用了再生(sheng)(sheng)(sheng)料生(sheng)(sheng)(sheng)產(chan)，以降低產(chan)品成(cheng)本(ben)，二是(shi)不(bu)具備生(sheng)(sheng)(sheng)產(chan)資格(ge)小型企業。

4、導(dao)體(ti)電(dian)(dian)(dian)(dian)阻(zu)不合格的(de)電(dian)(dian)(dian)(dian)線(xian)。導(dao)體(ti)電(dian)(dian)(dian)(dian)阻(zu)主要(yao)(yao)(yao)是考核(he)電(dian)(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)(dian)纜的(de)導(dao)體(ti)材(cai)料(liao)以及截(jie)面是否符合的(de)重(zhong)要(yao)(yao)(yao)指標(biao)。當導(dao)體(ti)電(dian)(dian)(dian)(dian)阻(zu)超標(biao)時(shi)，就(jiu)增大了(le)電(dian)(dian)(dian)(dian)流在線(xian)路上通過時(shi)的(de)損耗，加劇了(le)電(dian)(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)(dian)纜的(de)發熱。導(dao)體(ti)電(dian)(dian)(dian)(dian)阻(zu)不合格的(de)原(yuan)因，主要(yao)(yao)(yao)進(jin)企業為了(le)降(jiang)低成(cheng)本(ben)，將(jiang)占原(yuan)材(cai)料(liao)成(cheng)本(ben)80%的(de)銅材(cai)縮水，要(yao)(yao)(yao)么(me)降(jiang)低導(dao)體(ti)的(de)截(jie)面積，要(yao)(yao)(yao)么(me)使用含雜質過高(gao)的(de)再生銅，這樣(yang)致使電(dian)(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)(dian)纜的(de)導(dao)體(ti)電(dian)(dian)(dian)(dian)阻(zu)嚴(yan)重(zhong)超標(biao)，在使用過程中除易引發火災(zai)，還會(hui)加速(su)包覆在電(dian)(dian)(dian)(dian)線(xian)外的(de)絕緣層的(de)老化。

在購買電(dian)(dian)線(xian)電(dian)(dian)纜的過程中(zhong)，消費者應注意(yi)以下幾個事

第(di)一、要觀察(cha)電線(xian)(xian)的外觀。合格產(chan)品的絕緣(yuan)（護套）層柔軟、有韌(ren)性和伸縮性、表面層緊(jin)密、光滑(hua)、無粗糙(cao)感。如果包裹電線(xian)(xian)的塑料(liao)很容易被剝去(qu)，則存在塑料(liao)強度不夠(gou)的問題。

第(di)二(er)、要看(kan)電線的(de)(de)截面(mian)(mian)。合格(ge)產(chan)品的(de)(de)銅芯或鋁芯表(biao)面(mian)(mian)應(ying)該(gai)具有金屬光澤，表(biao)面(mian)(mian)發(fa)黑(hei)的(de)(de)銅或表(biao)面(mian)(mian)發(fa)白的(de)(de)鋁說明已(yi)被氧化(hua)。

第三、在購買電線(xian)時應注意查看(kan)質(zhi)量合格證書。如果(guo)電線(xian)的質(zhi)量合格，那么其電線(xian)質(zhi)量應該也受(shou)過檢驗，不會有太(tai)大的問題(ti)。
