不合(he)格(ge)電線電纜的危害

電(dian)(dian)線電(dian)(dian)纜(lan)是用于(yu)傳輸(shu)電(dian)(dian)力、傳輸(shu)信息(xi)和實(shi)現(xian)電(dian)(dian)磁(ci)能量轉換的一(yi)大類電(dian)(dian)工產品。在抽查過程中(zhong)，發現(xian)了(le)大量的不合格產品，這些(xie)劣質產品給電(dian)(dian)力系統(tong)正常運行埋下諸多隱(yin)患。

1、標(biao)(biao)志(zhi)不合(he)格(ge)的(de)電(dian)線電(dian)纜(lan)。標(biao)(biao)志(zhi)是電(dian)線電(dian)纜(lan)使用識(shi)(shi)別(bie)產(chan)品基本信息的(de)主要途(tu)徑(jing)，根(gen)據標(biao)(biao)準(zhun)規定標(biao)(biao)志(zhi)的(de)主要內容是：產(chan)品型號、規格(ge)、標(biao)(biao)準(zhun)號、廠名、產(chan)地等在(zai)一(yi)定的(de)標(biao)(biao)示(shi)間距內，當標(biao)(biao)志(zhi)不合(he)格(ge)時，會造成施工人(ren)員識(shi)(shi)別(bie)錯(cuo)誤，嚴重時會引發電(dian)氣事故。

2、結(jie)構尺寸(cun)不合格的(de)(de)(de)電(dian)線(xian)(xian)電(dian)纜(lan)(lan)。結(jie)構尺寸(cun)的(de)(de)(de)主要問題是護(hu)套(tao)厚(hou)度(du)，絕緣(yuan)厚(hou)度(du)，當(dang)電(dian)纜(lan)(lan)的(de)(de)(de)護(hu)套(tao)和絕緣(yuan)厚(hou)度(du)不達標時(shi)，致使電(dian)線(xian)(xian)電(dian)纜(lan)(lan)耐電(dian)氣強度(du)會嚴重降低，導致電(dian)線(xian)(xian)電(dian)纜(lan)(lan)的(de)(de)(de)使用(yong)壽命縮短(duan)，嚴重時(shi)可(ke)導致電(dian)線(xian)(xian)電(dian)纜(lan)(lan)被擊穿，絕緣(yuan)（護(hu)套(tao)）層起不到正常保護(hu)作用(yong)，從(cong)而發生電(dian)氣短(duan)路和火災等現(xian)象。

3、護套(tao)式絕緣老化前(qian)的抗張強度、伸(shen)長率(lv)合(he)(he)格(ge)的電(dian)線電(dian)纜。絕緣護套(tao)老化前(qian)的抗張強度、伸(shen)長率(lv)不(bu)合(he)(he)格(ge)直接大大縮(suo)短(duan)電(dian)線電(dian)纜的工作用(yong)(yong)壽命(ming)，而(er)且(qie)在施工或在長時(shi)間通電(dian)且(qie)溫度較高的環境中(zhong)，極(ji)易出現絕緣體斷裂，致使(shi)帶電(dian)導體裸(luo)露(lu)，發生(sheng)(sheng)能觸電(dian)式短(duan)路(lu)危(wei)險(xian)。其(qi)不(bu)合(he)(he)格(ge)的主要原因是使(shi)用(yong)(yong)了再生(sheng)(sheng)料生(sheng)(sheng)產，以降低產品成本(ben)，二(er)是不(bu)具備(bei)生(sheng)(sheng)產資格(ge)小型企業。

4、導(dao)(dao)體電(dian)(dian)(dian)阻不(bu)合格的(de)(de)(de)電(dian)(dian)(dian)線(xian)(xian)。導(dao)(dao)體電(dian)(dian)(dian)阻主要是考核電(dian)(dian)(dian)線(xian)(xian)電(dian)(dian)(dian)纜的(de)(de)(de)導(dao)(dao)體材(cai)料以及截面是否符合的(de)(de)(de)重(zhong)要指標(biao)。當導(dao)(dao)體電(dian)(dian)(dian)阻超標(biao)時，就增大(da)了(le)電(dian)(dian)(dian)流在線(xian)(xian)路(lu)上通過時的(de)(de)(de)損耗(hao)，加(jia)劇了(le)電(dian)(dian)(dian)線(xian)(xian)電(dian)(dian)(dian)纜的(de)(de)(de)發熱。導(dao)(dao)體電(dian)(dian)(dian)阻不(bu)合格的(de)(de)(de)原因，主要進(jin)企業為了(le)降低成本(ben)，將占原材(cai)料成本(ben)80%的(de)(de)(de)銅材(cai)縮水，要么降低導(dao)(dao)體的(de)(de)(de)截面積(ji)，要么使(shi)用(yong)含雜質(zhi)過高的(de)(de)(de)再(zai)生銅，這樣致使(shi)電(dian)(dian)(dian)線(xian)(xian)電(dian)(dian)(dian)纜的(de)(de)(de)導(dao)(dao)體電(dian)(dian)(dian)阻嚴重(zhong)超標(biao)，在使(shi)用(yong)過程中(zhong)除易引發火災，還會加(jia)速包覆在電(dian)(dian)(dian)線(xian)(xian)外的(de)(de)(de)絕緣(yuan)層(ceng)的(de)(de)(de)老化(hua)。

在購買電(dian)(dian)線電(dian)(dian)纜的過程(cheng)中，消費者應注意以(yi)下幾個事

第一(yi)、要(yao)觀(guan)察電線(xian)的(de)外觀(guan)。合(he)格產品的(de)絕(jue)緣（護套(tao)）層柔軟、有韌性(xing)和(he)伸(shen)縮性(xing)、表面(mian)層緊密、光滑、無粗糙感。如果包裹電線(xian)的(de)塑料很容易被剝去，則存在塑料強度不夠的(de)問題(ti)。

第二、要看(kan)電線(xian)的截面。合格產(chan)品的銅芯(xin)或鋁芯(xin)表(biao)面應(ying)該(gai)具有金(jin)屬(shu)光澤，表(biao)面發(fa)黑的銅或表(biao)面發(fa)白(bai)的鋁說明(ming)已被氧化。

第三(san)、在購買電(dian)線(xian)時應(ying)注意查看質量合格(ge)證書。如果電(dian)線(xian)的質量合格(ge)，那(nei)么其電(dian)線(xian)質量應(ying)該也受過檢驗，不會有太大的問題(ti)。
