不合格電線(xian)電纜的危害

電(dian)線電(dian)纜是用于(yu)傳輸電(dian)力、傳輸信息和(he)實現電(dian)磁能量轉(zhuan)換的一大(da)類電(dian)工產品。在抽查過程中，發(fa)現了大(da)量的不(bu)合格產品，這(zhe)些劣質產品給電(dian)力系統正常運行埋下(xia)諸多(duo)隱患。

1、標(biao)(biao)志不合格的(de)電(dian)線電(dian)纜。標(biao)(biao)志是電(dian)線電(dian)纜使用識(shi)別產品基(ji)本信息的(de)主要途徑(jing)，根據標(biao)(biao)準(zhun)規定標(biao)(biao)志的(de)主要內容是：產品型號、規格、標(biao)(biao)準(zhun)號、廠名(ming)、產地(di)等在一定的(de)標(biao)(biao)示間(jian)距內，當標(biao)(biao)志不合格時，會造成施(shi)工(gong)人員識(shi)別錯誤(wu)，嚴重時會引發電(dian)氣事(shi)故(gu)。

2、結構尺寸不合格的(de)(de)電(dian)(dian)線電(dian)(dian)纜(lan)。結構尺寸的(de)(de)主(zhu)要問(wen)題是護套(tao)(tao)(tao)厚(hou)(hou)度，絕(jue)緣厚(hou)(hou)度，當電(dian)(dian)纜(lan)的(de)(de)護套(tao)(tao)(tao)和(he)絕(jue)緣厚(hou)(hou)度不達(da)標(biao)時，致使電(dian)(dian)線電(dian)(dian)纜(lan)耐電(dian)(dian)氣(qi)強(qiang)度會嚴(yan)重降低(di)，導致電(dian)(dian)線電(dian)(dian)纜(lan)的(de)(de)使用(yong)壽命縮短，嚴(yan)重時可(ke)導致電(dian)(dian)線電(dian)(dian)纜(lan)被(bei)擊穿，絕(jue)緣（護套(tao)(tao)(tao)）層(ceng)起(qi)不到正常保護作用(yong)，從而發生電(dian)(dian)氣(qi)短路和(he)火災等現象。

3、護(hu)套式絕(jue)緣(yuan)老化(hua)前的(de)(de)抗張(zhang)強(qiang)度、伸長(chang)率合(he)格(ge)的(de)(de)電(dian)線(xian)電(dian)纜。絕(jue)緣(yuan)護(hu)套老化(hua)前的(de)(de)抗張(zhang)強(qiang)度、伸長(chang)率不合(he)格(ge)直接大(da)大(da)縮短(duan)電(dian)線(xian)電(dian)纜的(de)(de)工(gong)作用壽命，而且在施工(gong)或在長(chang)時間(jian)通電(dian)且溫度較高的(de)(de)環(huan)境中，極易出現絕(jue)緣(yuan)體(ti)斷裂(lie)，致使(shi)帶電(dian)導體(ti)裸露，發生(sheng)能觸電(dian)式短(duan)路危(wei)險(xian)。其不合(he)格(ge)的(de)(de)主要原(yuan)因是使(shi)用了再生(sheng)料生(sheng)產，以(yi)降(jiang)低產品(pin)成本(ben)，二是不具備生(sheng)產資格(ge)小型企業。

4、導(dao)體(ti)電(dian)阻(zu)(zu)(zu)不合(he)格(ge)的(de)電(dian)線。導(dao)體(ti)電(dian)阻(zu)(zu)(zu)主要是考核電(dian)線電(dian)纜(lan)的(de)導(dao)體(ti)材(cai)料以(yi)及(ji)截(jie)面是否符合(he)的(de)重(zhong)要指標(biao)。當(dang)導(dao)體(ti)電(dian)阻(zu)(zu)(zu)超標(biao)時(shi)(shi)，就增大了(le)電(dian)流在線路上通過(guo)時(shi)(shi)的(de)損耗，加劇了(le)電(dian)線電(dian)纜(lan)的(de)發熱。導(dao)體(ti)電(dian)阻(zu)(zu)(zu)不合(he)格(ge)的(de)原因，主要進企業為了(le)降低(di)成(cheng)本，將占原材(cai)料成(cheng)本80%的(de)銅(tong)(tong)材(cai)縮(suo)水(shui)，要么(me)降低(di)導(dao)體(ti)的(de)截(jie)面積(ji)，要么(me)使(shi)用(yong)含雜質過(guo)高(gao)的(de)再生銅(tong)(tong)，這(zhe)樣致使(shi)電(dian)線電(dian)纜(lan)的(de)導(dao)體(ti)電(dian)阻(zu)(zu)(zu)嚴重(zhong)超標(biao)，在使(shi)用(yong)過(guo)程中(zhong)除易引發火災，還會加速包覆在電(dian)線外的(de)絕緣層的(de)老化。

在購(gou)買(mai)電線電纜的過(guo)程中(zhong)，消(xiao)費者(zhe)應注意以下(xia)幾個(ge)事(shi)

第(di)一(yi)、要觀察(cha)電(dian)線(xian)的外觀。合格(ge)產品的絕緣（護套）層(ceng)柔(rou)軟、有韌性和伸縮性、表面(mian)層(ceng)緊密、光(guang)滑(hua)、無(wu)粗糙感。如果包裹電(dian)線(xian)的塑(su)料很容(rong)易被剝去，則存在(zai)塑(su)料強度不夠的問題。

第二、要(yao)看(kan)電(dian)線的(de)截面(mian)。合格產(chan)品的(de)銅芯或鋁(lv)芯表(biao)面(mian)應該具有金(jin)屬光(guang)澤，表(biao)面(mian)發黑的(de)銅或表(biao)面(mian)發白的(de)鋁(lv)說明已被(bei)氧化。

第(di)三、在(zai)購(gou)買電(dian)線(xian)(xian)時應(ying)注意查看(kan)質(zhi)量(liang)(liang)合(he)格證書(shu)。如果電(dian)線(xian)(xian)的(de)質(zhi)量(liang)(liang)合(he)格，那(nei)么其電(dian)線(xian)(xian)質(zhi)量(liang)(liang)應(ying)該也(ye)受過檢驗，不會有(you)太大的(de)問題。
