不合格電線電纜(lan)的危害

電(dian)(dian)線電(dian)(dian)纜(lan)是用(yong)于傳(chuan)輸電(dian)(dian)力(li)、傳(chuan)輸信息和(he)實現電(dian)(dian)磁能(neng)量轉換(huan)的一大類(lei)電(dian)(dian)工產(chan)品(pin)(pin)(pin)。在抽查過程中，發現了大量的不合(he)格產(chan)品(pin)(pin)(pin)，這些劣質產(chan)品(pin)(pin)(pin)給電(dian)(dian)力(li)系統(tong)正常運(yun)行埋(mai)下諸多隱患。

1、標志(zhi)不合(he)格(ge)的(de)電(dian)線電(dian)纜。標志(zhi)是電(dian)線電(dian)纜使用識(shi)別產(chan)品基本(ben)信(xin)息的(de)主要途徑，根(gen)據標準規(gui)定標志(zhi)的(de)主要內(nei)容是：產(chan)品型(xing)號、規(gui)格(ge)、標準號、廠(chang)名、產(chan)地等在一定的(de)標示間距內(nei)，當(dang)標志(zhi)不合(he)格(ge)時(shi)，會(hui)造成(cheng)施(shi)工人員識(shi)別錯誤(wu)，嚴重時(shi)會(hui)引(yin)發電(dian)氣(qi)事故(gu)。

2、結(jie)構尺寸不合格的電(dian)(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)(dian)纜(lan)。結(jie)構尺寸的主要(yao)問題(ti)是(shi)護(hu)套厚(hou)度(du)，絕(jue)緣(yuan)厚(hou)度(du)，當電(dian)(dian)(dian)(dian)纜(lan)的護(hu)套和(he)(he)絕(jue)緣(yuan)厚(hou)度(du)不達標(biao)時，致使電(dian)(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)(dian)纜(lan)耐電(dian)(dian)(dian)(dian)氣強度(du)會(hui)嚴重降(jiang)低，導(dao)(dao)致電(dian)(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)(dian)纜(lan)的使用(yong)(yong)壽命(ming)縮短(duan)，嚴重時可(ke)導(dao)(dao)致電(dian)(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)(dian)纜(lan)被擊(ji)穿，絕(jue)緣(yuan)（護(hu)套）層(ceng)起不到(dao)正常保護(hu)作用(yong)(yong)，從而發(fa)生電(dian)(dian)(dian)(dian)氣短(duan)路和(he)(he)火(huo)災等現象。

3、護(hu)套式(shi)絕緣老(lao)化(hua)前的(de)(de)(de)(de)抗張(zhang)強(qiang)度(du)、伸(shen)長率合格的(de)(de)(de)(de)電線(xian)電纜(lan)。絕緣護(hu)套老(lao)化(hua)前的(de)(de)(de)(de)抗張(zhang)強(qiang)度(du)、伸(shen)長率不(bu)合格直接(jie)大大縮短電線(xian)電纜(lan)的(de)(de)(de)(de)工(gong)作用壽命，而且在(zai)施工(gong)或在(zai)長時間通電且溫度(du)較(jiao)高的(de)(de)(de)(de)環(huan)境中，極易出現(xian)絕緣體(ti)斷裂，致使帶(dai)電導體(ti)裸露，發生(sheng)能觸電式(shi)短路危險。其不(bu)合格的(de)(de)(de)(de)主要原因(yin)是使用了(le)再(zai)生(sheng)料生(sheng)產，以降低(di)產品成本(ben)，二是不(bu)具備生(sheng)產資格小型企業。

4、導(dao)體(ti)(ti)電(dian)(dian)(dian)(dian)阻(zu)不合格(ge)的(de)(de)(de)電(dian)(dian)(dian)(dian)線(xian)(xian)(xian)。導(dao)體(ti)(ti)電(dian)(dian)(dian)(dian)阻(zu)主(zhu)(zhu)要(yao)(yao)是考核電(dian)(dian)(dian)(dian)線(xian)(xian)(xian)電(dian)(dian)(dian)(dian)纜(lan)的(de)(de)(de)導(dao)體(ti)(ti)材料(liao)以及截面(mian)是否符合的(de)(de)(de)重要(yao)(yao)指標(biao)。當導(dao)體(ti)(ti)電(dian)(dian)(dian)(dian)阻(zu)超標(biao)時，就增大了(le)電(dian)(dian)(dian)(dian)流(liu)在(zai)線(xian)(xian)(xian)路上通(tong)過時的(de)(de)(de)損耗，加劇了(le)電(dian)(dian)(dian)(dian)線(xian)(xian)(xian)電(dian)(dian)(dian)(dian)纜(lan)的(de)(de)(de)發(fa)(fa)熱。導(dao)體(ti)(ti)電(dian)(dian)(dian)(dian)阻(zu)不合格(ge)的(de)(de)(de)原因，主(zhu)(zhu)要(yao)(yao)進企業為了(le)降低成本(ben)，將占原材料(liao)成本(ben)80%的(de)(de)(de)銅材縮水，要(yao)(yao)么(me)降低導(dao)體(ti)(ti)的(de)(de)(de)截面(mian)積，要(yao)(yao)么(me)使用(yong)含雜質過高的(de)(de)(de)再生銅，這樣(yang)致(zhi)使電(dian)(dian)(dian)(dian)線(xian)(xian)(xian)電(dian)(dian)(dian)(dian)纜(lan)的(de)(de)(de)導(dao)體(ti)(ti)電(dian)(dian)(dian)(dian)阻(zu)嚴重超標(biao)，在(zai)使用(yong)過程(cheng)中(zhong)除易(yi)引發(fa)(fa)火災，還會加速包覆在(zai)電(dian)(dian)(dian)(dian)線(xian)(xian)(xian)外的(de)(de)(de)絕緣(yuan)層的(de)(de)(de)老化(hua)。

在購買電(dian)線電(dian)纜的過程中，消費者應(ying)注意以(yi)下幾個事

第(di)一(yi)、要觀察電線(xian)的外觀。合格(ge)產品的絕緣（護套(tao)）層柔軟、有韌性(xing)和伸縮性(xing)、表面層緊(jin)密、光滑、無粗糙(cao)感。如果包(bao)裹電線(xian)的塑料很(hen)容(rong)易被(bei)剝去(qu)，則(ze)存在(zai)塑料強度不夠(gou)的問題。

第(di)二、要看(kan)電線(xian)的(de)截(jie)面。合格產(chan)品(pin)的(de)銅(tong)(tong)芯或(huo)(huo)鋁芯表(biao)面應該具有(you)金(jin)屬光澤，表(biao)面發黑的(de)銅(tong)(tong)或(huo)(huo)表(biao)面發白的(de)鋁說明已被(bei)氧(yang)化。

第(di)三(san)、在購買(mai)電(dian)(dian)線(xian)時(shi)應注意查(cha)看質(zhi)量合格證書。如果(guo)電(dian)(dian)線(xian)的質(zhi)量合格，那么(me)其電(dian)(dian)線(xian)質(zhi)量應該也受過檢驗(yan)，不會(hui)有太大的問題(ti)。
