不合格電(dian)線電(dian)纜的危(wei)害

電(dian)線電(dian)纜(lan)是(shi)用于(yu)傳輸電(dian)力、傳輸信息和(he)實現電(dian)磁能量轉換的(de)一大類電(dian)工產品。在抽查過程中(zhong)，發現了(le)大量的(de)不合(he)格產品，這些劣質產品給電(dian)力系(xi)統正常(chang)運(yun)行埋下諸多隱患(huan)。

1、標(biao)志(zhi)(zhi)不合格的(de)電線電纜。標(biao)志(zhi)(zhi)是電線電纜使用(yong)識別(bie)產(chan)(chan)品基本(ben)信(xin)息的(de)主(zhu)要途徑(jing)，根(gen)據(ju)標(biao)準(zhun)(zhun)規定標(biao)志(zhi)(zhi)的(de)主(zhu)要內容是：產(chan)(chan)品型號、規格、標(biao)準(zhun)(zhun)號、廠名、產(chan)(chan)地(di)等在一定的(de)標(biao)示間距內，當標(biao)志(zhi)(zhi)不合格時(shi)，會造成(cheng)施工人員識別(bie)錯誤(wu)，嚴重時(shi)會引(yin)發電氣事(shi)故。

2、結構(gou)尺(chi)寸不(bu)合格的(de)(de)電(dian)線電(dian)纜(lan)(lan)。結構(gou)尺(chi)寸的(de)(de)主(zhu)要(yao)問題是護(hu)(hu)套厚度(du)，絕(jue)緣厚度(du)，當電(dian)纜(lan)(lan)的(de)(de)護(hu)(hu)套和絕(jue)緣厚度(du)不(bu)達(da)標時，致使(shi)電(dian)線電(dian)纜(lan)(lan)耐電(dian)氣強度(du)會嚴重(zhong)降(jiang)低，導致電(dian)線電(dian)纜(lan)(lan)的(de)(de)使(shi)用(yong)壽命縮短(duan)，嚴重(zhong)時可導致電(dian)線電(dian)纜(lan)(lan)被(bei)擊穿，絕(jue)緣（護(hu)(hu)套）層起不(bu)到正常保護(hu)(hu)作用(yong)，從(cong)而發生(sheng)電(dian)氣短(duan)路和火災等現(xian)象。

3、護套式(shi)絕緣老化(hua)前(qian)的(de)抗張強(qiang)度(du)、伸(shen)長(chang)率合格(ge)的(de)電線(xian)電纜(lan)(lan)。絕緣護套老化(hua)前(qian)的(de)抗張強(qiang)度(du)、伸(shen)長(chang)率不合格(ge)直接大(da)大(da)縮短電線(xian)電纜(lan)(lan)的(de)工作(zuo)用壽(shou)命(ming)，而且在施(shi)工或在長(chang)時間通電且溫度(du)較(jiao)高的(de)環境中，極(ji)易出現(xian)絕緣體(ti)斷裂(lie)，致使(shi)帶電導體(ti)裸露，發生能觸電式(shi)短路(lu)危(wei)險。其不合格(ge)的(de)主(zhu)要原因是使(shi)用了再(zai)生料生產(chan)，以降低產(chan)品成本，二(er)是不具備生產(chan)資格(ge)小型企業。

4、導(dao)體電(dian)(dian)(dian)(dian)阻(zu)不(bu)合格(ge)的(de)(de)電(dian)(dian)(dian)(dian)線。導(dao)體電(dian)(dian)(dian)(dian)阻(zu)主要(yao)(yao)是考核電(dian)(dian)(dian)(dian)線電(dian)(dian)(dian)(dian)纜的(de)(de)導(dao)體材料(liao)(liao)以及截(jie)面是否符合的(de)(de)重要(yao)(yao)指標(biao)。當導(dao)體電(dian)(dian)(dian)(dian)阻(zu)超(chao)標(biao)時(shi)，就增大(da)了(le)電(dian)(dian)(dian)(dian)流在線路上通過(guo)時(shi)的(de)(de)損耗，加劇了(le)電(dian)(dian)(dian)(dian)線電(dian)(dian)(dian)(dian)纜的(de)(de)發(fa)熱。導(dao)體電(dian)(dian)(dian)(dian)阻(zu)不(bu)合格(ge)的(de)(de)原(yuan)(yuan)因(yin)，主要(yao)(yao)進企業為了(le)降低成(cheng)本，將占原(yuan)(yuan)材料(liao)(liao)成(cheng)本80%的(de)(de)銅材縮水，要(yao)(yao)么降低導(dao)體的(de)(de)截(jie)面積，要(yao)(yao)么使(shi)用含雜質過(guo)高的(de)(de)再(zai)生銅，這(zhe)樣(yang)致(zhi)使(shi)電(dian)(dian)(dian)(dian)線電(dian)(dian)(dian)(dian)纜的(de)(de)導(dao)體電(dian)(dian)(dian)(dian)阻(zu)嚴(yan)重超(chao)標(biao)，在使(shi)用過(guo)程中除易(yi)引(yin)發(fa)火災(zai)，還會加速(su)包覆(fu)在電(dian)(dian)(dian)(dian)線外的(de)(de)絕緣層的(de)(de)老化(hua)。

在(zai)購買電線電纜的過(guo)程中(zhong)，消費者(zhe)應注意(yi)以下(xia)幾個事

第一、要觀(guan)察電線的(de)外觀(guan)。合格產品的(de)絕緣(yuan)（護套）層柔(rou)軟、有韌(ren)性(xing)和伸縮性(xing)、表面層緊(jin)密、光滑、無粗糙(cao)感(gan)。如果(guo)包裹電線的(de)塑料很容易被剝去(qu)，則(ze)存在(zai)塑料強度不夠(gou)的(de)問題(ti)。

第二(er)、要看電線的(de)截面。合格產品的(de)銅芯或(huo)(huo)鋁(lv)(lv)芯表面應(ying)該具有金屬(shu)光澤，表面發(fa)黑的(de)銅或(huo)(huo)表面發(fa)白的(de)鋁(lv)(lv)說明已被氧化。

第(di)三、在(zai)購買電(dian)線(xian)時應注意查看質量合格證書(shu)。如果電(dian)線(xian)的質量合格，那么其電(dian)線(xian)質量應該也(ye)受過檢驗，不會有太大的問題(ti)。
