不(bu)合(he)格電線電纜的危害

電(dian)線電(dian)纜是(shi)用于傳(chuan)輸(shu)電(dian)力(li)、傳(chuan)輸(shu)信息和實現(xian)電(dian)磁能量(liang)轉換的(de)一大類電(dian)工產品。在抽查(cha)過(guo)程(cheng)中，發(fa)現(xian)了大量(liang)的(de)不合格產品，這些劣(lie)質產品給(gei)電(dian)力(li)系統正常運行埋下諸多隱(yin)患。

1、標志不合(he)(he)格的(de)電(dian)線電(dian)纜。標志是(shi)(shi)電(dian)線電(dian)纜使用識別產(chan)(chan)(chan)品(pin)基(ji)本信息的(de)主要(yao)途徑，根據(ju)標準規定標志的(de)主要(yao)內容是(shi)(shi)：產(chan)(chan)(chan)品(pin)型(xing)號、規格、標準號、廠名、產(chan)(chan)(chan)地等(deng)在(zai)一定的(de)標示間距內，當標志不合(he)(he)格時，會造成施工人員(yuan)識別錯誤，嚴重時會引發電(dian)氣事故。

2、結構尺寸(cun)不(bu)合格的(de)電(dian)(dian)(dian)(dian)(dian)線電(dian)(dian)(dian)(dian)(dian)纜。結構尺寸(cun)的(de)主要問題是護(hu)套(tao)厚(hou)(hou)度(du)，絕(jue)(jue)緣(yuan)(yuan)厚(hou)(hou)度(du)，當(dang)電(dian)(dian)(dian)(dian)(dian)纜的(de)護(hu)套(tao)和絕(jue)(jue)緣(yuan)(yuan)厚(hou)(hou)度(du)不(bu)達標(biao)時，致(zhi)使電(dian)(dian)(dian)(dian)(dian)線電(dian)(dian)(dian)(dian)(dian)纜耐電(dian)(dian)(dian)(dian)(dian)氣強(qiang)度(du)會嚴重降低，導致(zhi)電(dian)(dian)(dian)(dian)(dian)線電(dian)(dian)(dian)(dian)(dian)纜的(de)使用壽命縮短(duan)，嚴重時可導致(zhi)電(dian)(dian)(dian)(dian)(dian)線電(dian)(dian)(dian)(dian)(dian)纜被擊穿，絕(jue)(jue)緣(yuan)(yuan)（護(hu)套(tao)）層起不(bu)到正常保護(hu)作(zuo)用，從而(er)發生電(dian)(dian)(dian)(dian)(dian)氣短(duan)路(lu)和火災等現象(xiang)。

3、護套式(shi)絕緣老化(hua)前的(de)(de)抗(kang)張強度(du)、伸(shen)(shen)長(chang)(chang)率合格(ge)的(de)(de)電(dian)(dian)線(xian)電(dian)(dian)纜(lan)。絕緣護套老化(hua)前的(de)(de)抗(kang)張強度(du)、伸(shen)(shen)長(chang)(chang)率不(bu)合格(ge)直接大大縮短電(dian)(dian)線(xian)電(dian)(dian)纜(lan)的(de)(de)工作用壽命，而且(qie)在施工或在長(chang)(chang)時間(jian)通(tong)電(dian)(dian)且(qie)溫(wen)度(du)較高的(de)(de)環境中，極(ji)易出現絕緣體斷裂，致使(shi)帶電(dian)(dian)導體裸露，發生能觸電(dian)(dian)式(shi)短路危險。其不(bu)合格(ge)的(de)(de)主要原(yuan)因是(shi)使(shi)用了再(zai)生料生產(chan)，以(yi)降(jiang)低(di)產(chan)品成(cheng)本(ben)，二是(shi)不(bu)具備(bei)生產(chan)資(zi)格(ge)小型企業。

4、導(dao)體電(dian)(dian)阻(zu)不合格的(de)(de)(de)電(dian)(dian)線(xian)(xian)(xian)。導(dao)體電(dian)(dian)阻(zu)主要(yao)是(shi)(shi)考核電(dian)(dian)線(xian)(xian)(xian)電(dian)(dian)纜的(de)(de)(de)導(dao)體材料(liao)以(yi)及截(jie)(jie)面(mian)是(shi)(shi)否符(fu)合的(de)(de)(de)重要(yao)指標。當導(dao)體電(dian)(dian)阻(zu)超標時，就增大(da)了電(dian)(dian)流在線(xian)(xian)(xian)路(lu)上通過(guo)時的(de)(de)(de)損耗，加劇了電(dian)(dian)線(xian)(xian)(xian)電(dian)(dian)纜的(de)(de)(de)發熱。導(dao)體電(dian)(dian)阻(zu)不合格的(de)(de)(de)原因，主要(yao)進企業為了降(jiang)低(di)成(cheng)本，將占原材料(liao)成(cheng)本80%的(de)(de)(de)銅材縮水，要(yao)么降(jiang)低(di)導(dao)體的(de)(de)(de)截(jie)(jie)面(mian)積，要(yao)么使(shi)(shi)用含雜質(zhi)過(guo)高的(de)(de)(de)再生銅，這(zhe)樣致使(shi)(shi)電(dian)(dian)線(xian)(xian)(xian)電(dian)(dian)纜的(de)(de)(de)導(dao)體電(dian)(dian)阻(zu)嚴(yan)重超標，在使(shi)(shi)用過(guo)程(cheng)中除易(yi)引發火災，還會(hui)加速包覆在電(dian)(dian)線(xian)(xian)(xian)外的(de)(de)(de)絕緣層(ceng)的(de)(de)(de)老(lao)化。

在(zai)購買電(dian)線電(dian)纜的過程中(zhong)，消費者應注意以下幾個(ge)事

第一、要觀察電線的(de)外(wai)觀。合格產品(pin)的(de)絕緣（護(hu)套）層(ceng)柔(rou)軟、有韌性和伸縮性、表面(mian)層(ceng)緊(jin)密、光(guang)滑、無(wu)粗糙(cao)感。如果(guo)包裹電線的(de)塑料很容(rong)易被(bei)剝去(qu)，則存在(zai)塑料強度(du)不夠的(de)問題。

第二(er)、要(yao)看電線的截面。合格(ge)產品(pin)的銅芯(xin)或(huo)鋁(lv)芯(xin)表面應該具有(you)金屬(shu)光澤，表面發黑的銅或(huo)表面發白的鋁(lv)說明已被氧化。

第三、在購買電(dian)線(xian)時應(ying)(ying)注意查看質量合(he)格(ge)證(zheng)書(shu)。如果電(dian)線(xian)的質量合(he)格(ge)，那(nei)么其(qi)電(dian)線(xian)質量應(ying)(ying)該也受(shou)過檢驗，不會有太大的問題(ti)。
