不合格電線電纜的危害

電(dian)(dian)線電(dian)(dian)纜(lan)是用于(yu)傳(chuan)輸電(dian)(dian)力、傳(chuan)輸信息和實現(xian)電(dian)(dian)磁能量轉(zhuan)換的(de)一(yi)大類(lei)電(dian)(dian)工(gong)產品(pin)。在抽查過程中，發(fa)現(xian)了大量的(de)不(bu)合(he)格產品(pin)，這些劣質產品(pin)給(gei)電(dian)(dian)力系統正常運行埋下諸多隱患。

1、標志(zhi)(zhi)(zhi)不合(he)格(ge)的(de)電(dian)線電(dian)纜。標志(zhi)(zhi)(zhi)是電(dian)線電(dian)纜使用識別(bie)產品基本(ben)信息的(de)主要途徑，根據標準(zhun)規定標志(zhi)(zhi)(zhi)的(de)主要內(nei)容是：產品型號(hao)、規格(ge)、標準(zhun)號(hao)、廠(chang)名、產地等在一(yi)定的(de)標示間距內(nei)，當(dang)標志(zhi)(zhi)(zhi)不合(he)格(ge)時，會造成施(shi)工人員(yuan)識別(bie)錯誤(wu)，嚴(yan)重(zhong)時會引發電(dian)氣事故(gu)。

2、結(jie)構(gou)尺寸不合格的電(dian)(dian)線(xian)電(dian)(dian)纜(lan)。結(jie)構(gou)尺寸的主要(yao)問題(ti)是護(hu)套(tao)厚度(du)，絕緣厚度(du)，當電(dian)(dian)纜(lan)的護(hu)套(tao)和(he)絕緣厚度(du)不達標時(shi)，致使(shi)電(dian)(dian)線(xian)電(dian)(dian)纜(lan)耐電(dian)(dian)氣強度(du)會嚴重降低，導致電(dian)(dian)線(xian)電(dian)(dian)纜(lan)的使(shi)用(yong)(yong)壽命縮短(duan)，嚴重時(shi)可導致電(dian)(dian)線(xian)電(dian)(dian)纜(lan)被擊穿，絕緣（護(hu)套(tao)）層起不到正常保護(hu)作用(yong)(yong)，從而發生電(dian)(dian)氣短(duan)路(lu)和(he)火(huo)災等現象。

3、護套式(shi)(shi)絕(jue)(jue)緣老化前(qian)的(de)抗張(zhang)強度(du)、伸(shen)長(chang)率合格(ge)的(de)電(dian)(dian)線(xian)(xian)電(dian)(dian)纜。絕(jue)(jue)緣護套老化前(qian)的(de)抗張(zhang)強度(du)、伸(shen)長(chang)率不(bu)合格(ge)直接大大縮(suo)短電(dian)(dian)線(xian)(xian)電(dian)(dian)纜的(de)工(gong)作用(yong)壽(shou)命(ming)，而且在施工(gong)或在長(chang)時(shi)間通電(dian)(dian)且溫度(du)較高的(de)環境中，極易出現絕(jue)(jue)緣體斷裂(lie)，致使(shi)帶電(dian)(dian)導體裸露，發生能觸電(dian)(dian)式(shi)(shi)短路危險。其不(bu)合格(ge)的(de)主要原因(yin)是(shi)使(shi)用(yong)了再(zai)生料(liao)生產，以降低產品成本，二是(shi)不(bu)具備生產資格(ge)小型企(qi)業(ye)。

4、導(dao)(dao)體(ti)電(dian)(dian)(dian)(dian)阻(zu)不合格的(de)(de)電(dian)(dian)(dian)(dian)線(xian)。導(dao)(dao)體(ti)電(dian)(dian)(dian)(dian)阻(zu)主要是考核電(dian)(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)(dian)纜的(de)(de)導(dao)(dao)體(ti)材(cai)(cai)料以及截面是否符合的(de)(de)重要指標(biao)。當導(dao)(dao)體(ti)電(dian)(dian)(dian)(dian)阻(zu)超(chao)標(biao)時，就增大了(le)電(dian)(dian)(dian)(dian)流在(zai)線(xian)路上通過時的(de)(de)損耗，加劇了(le)電(dian)(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)(dian)纜的(de)(de)發熱。導(dao)(dao)體(ti)電(dian)(dian)(dian)(dian)阻(zu)不合格的(de)(de)原因，主要進企業(ye)為了(le)降(jiang)(jiang)低成本(ben)，將占(zhan)原材(cai)(cai)料成本(ben)80%的(de)(de)銅(tong)材(cai)(cai)縮水，要么(me)降(jiang)(jiang)低導(dao)(dao)體(ti)的(de)(de)截面積，要么(me)使(shi)用(yong)含雜質過高的(de)(de)再(zai)生(sheng)銅(tong)，這(zhe)樣致使(shi)電(dian)(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)(dian)纜的(de)(de)導(dao)(dao)體(ti)電(dian)(dian)(dian)(dian)阻(zu)嚴重超(chao)標(biao)，在(zai)使(shi)用(yong)過程(cheng)中除(chu)易引發火災，還會加速包覆(fu)在(zai)電(dian)(dian)(dian)(dian)線(xian)外的(de)(de)絕緣層(ceng)的(de)(de)老(lao)化(hua)。

在(zai)購(gou)買電線電纜(lan)的過程中，消費(fei)者應注意以下幾個事

第(di)一(yi)、要觀察電(dian)線(xian)的(de)外觀。合格產品的(de)絕緣（護套(tao)）層柔軟、有韌性(xing)和伸縮性(xing)、表面層緊密(mi)、光(guang)滑、無粗糙感。如果(guo)包裹電(dian)線(xian)的(de)塑料(liao)很容易被剝去，則存在塑料(liao)強(qiang)度不夠(gou)的(de)問(wen)題(ti)。

第二、要看電線的(de)截面。合(he)格(ge)產品的(de)銅芯(xin)或鋁(lv)芯(xin)表面應該具有(you)金(jin)屬光澤，表面發黑的(de)銅或表面發白的(de)鋁(lv)說(shuo)明已被(bei)氧化。

第三、在購(gou)買電線時(shi)應注(zhu)意查看質(zhi)量合格證(zheng)書。如(ru)果(guo)電線的質(zhi)量合格，那么其(qi)電線質(zhi)量應該也(ye)受過檢驗，不會有(you)太大的問題。
