不合格電線(xian)電纜(lan)的危害

電線電纜是用(yong)于傳輸電力、傳輸信(xin)息(xi)和實現電磁(ci)能量轉換的一大類(lei)電工產品。在抽查(cha)過程中，發現了(le)大量的不合格產品，這些劣質產品給(gei)電力系統正常運(yun)行埋(mai)下諸多隱(yin)患。

1、標(biao)志(zhi)不(bu)合格的電(dian)(dian)線(xian)電(dian)(dian)纜。標(biao)志(zhi)是(shi)電(dian)(dian)線(xian)電(dian)(dian)纜使用識別產品(pin)(pin)基本信息(xi)的主要途徑，根據標(biao)準(zhun)規(gui)定標(biao)志(zhi)的主要內容是(shi)：產品(pin)(pin)型號(hao)、規(gui)格、標(biao)準(zhun)號(hao)、廠名、產地等(deng)在一(yi)定的標(biao)示間距(ju)內，當標(biao)志(zhi)不(bu)合格時(shi)，會造成施工人(ren)員(yuan)識別錯誤，嚴重時(shi)會引發電(dian)(dian)氣(qi)事故。

2、結構(gou)尺(chi)寸(cun)不合格的(de)電(dian)線(xian)(xian)電(dian)纜。結構(gou)尺(chi)寸(cun)的(de)主(zhu)要問(wen)題是護(hu)套(tao)厚度(du)，絕(jue)(jue)緣(yuan)厚度(du)，當電(dian)纜的(de)護(hu)套(tao)和絕(jue)(jue)緣(yuan)厚度(du)不達標時，致(zhi)(zhi)使電(dian)線(xian)(xian)電(dian)纜耐電(dian)氣(qi)強度(du)會(hui)嚴重降低，導(dao)致(zhi)(zhi)電(dian)線(xian)(xian)電(dian)纜的(de)使用(yong)壽命(ming)縮(suo)短(duan)，嚴重時可導(dao)致(zhi)(zhi)電(dian)線(xian)(xian)電(dian)纜被擊穿，絕(jue)(jue)緣(yuan)（護(hu)套(tao)）層起不到(dao)正(zheng)常(chang)保護(hu)作用(yong)，從而(er)發生電(dian)氣(qi)短(duan)路和火(huo)災等(deng)現象。

3、護套式絕緣老(lao)化前的抗張(zhang)強度、伸長率(lv)合(he)格(ge)的電(dian)(dian)線電(dian)(dian)纜。絕緣護套老(lao)化前的抗張(zhang)強度、伸長率(lv)不(bu)合(he)格(ge)直接大(da)大(da)縮短(duan)電(dian)(dian)線電(dian)(dian)纜的工作用(yong)壽命，而且(qie)在(zai)施工或在(zai)長時間通電(dian)(dian)且(qie)溫度較高的環境(jing)中，極易出現絕緣體斷裂，致使帶(dai)電(dian)(dian)導體裸(luo)露，發生(sheng)(sheng)(sheng)能觸電(dian)(dian)式短(duan)路危險。其(qi)不(bu)合(he)格(ge)的主(zhu)要原因是使用(yong)了(le)再生(sheng)(sheng)(sheng)料(liao)生(sheng)(sheng)(sheng)產，以降低產品成本，二是不(bu)具(ju)備生(sheng)(sheng)(sheng)產資格(ge)小型企業。

4、導(dao)體(ti)電(dian)(dian)(dian)阻(zu)(zu)不合格(ge)的(de)(de)電(dian)(dian)(dian)線(xian)(xian)。導(dao)體(ti)電(dian)(dian)(dian)阻(zu)(zu)主要(yao)(yao)是(shi)考核電(dian)(dian)(dian)線(xian)(xian)電(dian)(dian)(dian)纜(lan)的(de)(de)導(dao)體(ti)材料(liao)以及截面是(shi)否符合的(de)(de)重(zhong)要(yao)(yao)指標。當導(dao)體(ti)電(dian)(dian)(dian)阻(zu)(zu)超標時，就增大了電(dian)(dian)(dian)流在線(xian)(xian)路(lu)上(shang)通過時的(de)(de)損耗，加劇了電(dian)(dian)(dian)線(xian)(xian)電(dian)(dian)(dian)纜(lan)的(de)(de)發(fa)熱(re)。導(dao)體(ti)電(dian)(dian)(dian)阻(zu)(zu)不合格(ge)的(de)(de)原因，主要(yao)(yao)進企業(ye)為了降低成本，將占原材料(liao)成本80%的(de)(de)銅材縮(suo)水，要(yao)(yao)么降低導(dao)體(ti)的(de)(de)截面積，要(yao)(yao)么使(shi)用含雜質過高(gao)的(de)(de)再(zai)生銅，這樣致使(shi)電(dian)(dian)(dian)線(xian)(xian)電(dian)(dian)(dian)纜(lan)的(de)(de)導(dao)體(ti)電(dian)(dian)(dian)阻(zu)(zu)嚴重(zhong)超標，在使(shi)用過程中除易引發(fa)火災，還會加速(su)包覆在電(dian)(dian)(dian)線(xian)(xian)外的(de)(de)絕緣層的(de)(de)老化(hua)。

在購買電線電纜(lan)的過程中(zhong)，消(xiao)費者應(ying)注意以(yi)下幾(ji)個事

第一、要觀察電(dian)線的外觀。合格產品(pin)的絕緣(yuan)（護(hu)套）層(ceng)柔軟、有韌性和(he)伸縮性、表面層(ceng)緊密、光滑、無粗糙感。如(ru)果包(bao)裹電(dian)線的塑料(liao)很容易(yi)被剝(bo)去，則存在塑料(liao)強度(du)不夠的問題(ti)。

第二(er)、要看電(dian)線的(de)截(jie)面。合格(ge)產品的(de)銅芯或鋁芯表面應該(gai)具有金屬(shu)光澤(ze)，表面發(fa)黑的(de)銅或表面發(fa)白的(de)鋁說明已被氧(yang)化。

第三、在購買電(dian)線時應(ying)注意查看質(zhi)量(liang)(liang)合格證書。如(ru)果電(dian)線的質(zhi)量(liang)(liang)合格，那么(me)其(qi)電(dian)線質(zhi)量(liang)(liang)應(ying)該也受(shou)過(guo)檢驗(yan)，不會(hui)有(you)太(tai)大的問題。
