不合格電線電纜的危(wei)害

電(dian)線電(dian)纜(lan)是用于傳(chuan)輸電(dian)力、傳(chuan)輸信息和實現(xian)(xian)電(dian)磁能量轉換的(de)一大類電(dian)工(gong)產(chan)(chan)品(pin)。在抽查過程中(zhong)，發現(xian)(xian)了大量的(de)不(bu)合格產(chan)(chan)品(pin)，這些劣質產(chan)(chan)品(pin)給電(dian)力系統(tong)正常運行埋下諸多(duo)隱患。

1、標志(zhi)不(bu)合(he)(he)格的(de)電(dian)線電(dian)纜。標志(zhi)是(shi)電(dian)線電(dian)纜使(shi)用識(shi)別產品(pin)基本信息的(de)主(zhu)要(yao)(yao)途徑，根(gen)據(ju)標準(zhun)規定(ding)標志(zhi)的(de)主(zhu)要(yao)(yao)內容是(shi)：產品(pin)型號(hao)、規格、標準(zhun)號(hao)、廠名、產地等在(zai)一定(ding)的(de)標示間距內，當(dang)標志(zhi)不(bu)合(he)(he)格時，會造成施工人(ren)員(yuan)識(shi)別錯誤，嚴重時會引發電(dian)氣事故(gu)。

2、結構尺寸(cun)不(bu)(bu)合格的電(dian)(dian)線(xian)(xian)(xian)電(dian)(dian)纜(lan)(lan)(lan)。結構尺寸(cun)的主要問題是護(hu)(hu)套厚度(du)(du)，絕緣(yuan)厚度(du)(du)，當電(dian)(dian)纜(lan)(lan)(lan)的護(hu)(hu)套和絕緣(yuan)厚度(du)(du)不(bu)(bu)達標時，致使電(dian)(dian)線(xian)(xian)(xian)電(dian)(dian)纜(lan)(lan)(lan)耐電(dian)(dian)氣(qi)強度(du)(du)會嚴重降低，導(dao)致電(dian)(dian)線(xian)(xian)(xian)電(dian)(dian)纜(lan)(lan)(lan)的使用(yong)壽命縮(suo)短，嚴重時可導(dao)致電(dian)(dian)線(xian)(xian)(xian)電(dian)(dian)纜(lan)(lan)(lan)被擊穿，絕緣(yuan)（護(hu)(hu)套）層起不(bu)(bu)到正常保護(hu)(hu)作用(yong)，從(cong)而發(fa)生電(dian)(dian)氣(qi)短路和火災等現象。

3、護(hu)套式(shi)(shi)絕(jue)緣(yuan)老化前的(de)抗張強度(du)、伸(shen)長(chang)率合格(ge)的(de)電(dian)線(xian)電(dian)纜。絕(jue)緣(yuan)護(hu)套老化前的(de)抗張強度(du)、伸(shen)長(chang)率不(bu)合格(ge)直接大(da)大(da)縮短(duan)電(dian)線(xian)電(dian)纜的(de)工作用壽命，而(er)且在施(shi)工或在長(chang)時(shi)間(jian)通(tong)電(dian)且溫度(du)較高的(de)環(huan)境(jing)中，極易出現絕(jue)緣(yuan)體斷裂，致使帶(dai)電(dian)導(dao)體裸露(lu)，發生(sheng)(sheng)能(neng)觸電(dian)式(shi)(shi)短(duan)路危(wei)險。其不(bu)合格(ge)的(de)主要原因是使用了再生(sheng)(sheng)料生(sheng)(sheng)產，以(yi)降(jiang)低產品成本，二(er)是不(bu)具備(bei)生(sheng)(sheng)產資格(ge)小型企業。

4、導(dao)(dao)體(ti)(ti)電(dian)(dian)(dian)阻不合(he)格的(de)(de)(de)電(dian)(dian)(dian)線(xian)。導(dao)(dao)體(ti)(ti)電(dian)(dian)(dian)阻主(zhu)要是(shi)考核電(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)纜(lan)的(de)(de)(de)導(dao)(dao)體(ti)(ti)材料以(yi)及截(jie)面是(shi)否符(fu)合(he)的(de)(de)(de)重(zhong)要指標。當導(dao)(dao)體(ti)(ti)電(dian)(dian)(dian)阻超(chao)標時(shi)(shi)，就增大了(le)電(dian)(dian)(dian)流在線(xian)路上通(tong)過(guo)時(shi)(shi)的(de)(de)(de)損耗，加劇了(le)電(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)纜(lan)的(de)(de)(de)發熱。導(dao)(dao)體(ti)(ti)電(dian)(dian)(dian)阻不合(he)格的(de)(de)(de)原(yuan)因，主(zhu)要進企(qi)業為了(le)降低成(cheng)本，將占原(yuan)材料成(cheng)本80%的(de)(de)(de)銅材縮水，要么降低導(dao)(dao)體(ti)(ti)的(de)(de)(de)截(jie)面積，要么使(shi)用含雜質過(guo)高的(de)(de)(de)再生銅，這樣致使(shi)電(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)纜(lan)的(de)(de)(de)導(dao)(dao)體(ti)(ti)電(dian)(dian)(dian)阻嚴重(zhong)超(chao)標，在使(shi)用過(guo)程(cheng)中除易引發火災(zai)，還會加速包覆在電(dian)(dian)(dian)線(xian)外(wai)的(de)(de)(de)絕緣(yuan)層的(de)(de)(de)老化。

在購買電線電纜的過程(cheng)中，消費者(zhe)應(ying)注意以下幾個(ge)事

第一(yi)、要觀(guan)察電(dian)線(xian)的(de)外觀(guan)。合格產品的(de)絕緣（護套）層柔軟(ruan)、有韌性和伸縮性、表面(mian)層緊密、光滑(hua)、無粗糙感。如(ru)果包裹電(dian)線(xian)的(de)塑(su)料很容(rong)易被剝去，則(ze)存在(zai)塑(su)料強度不夠的(de)問題。

第二(er)、要看電(dian)線的(de)截面(mian)。合(he)格產品的(de)銅芯或鋁(lv)芯表(biao)面(mian)應該具有(you)金屬光澤(ze)，表(biao)面(mian)發黑的(de)銅或表(biao)面(mian)發白(bai)的(de)鋁(lv)說(shuo)明已被氧化。

第三、在購買電(dian)(dian)線(xian)時應(ying)注意查看質(zhi)(zhi)量(liang)合(he)格(ge)(ge)證書。如果電(dian)(dian)線(xian)的質(zhi)(zhi)量(liang)合(he)格(ge)(ge)，那(nei)么其電(dian)(dian)線(xian)質(zhi)(zhi)量(liang)應(ying)該也受過檢驗，不會有太大的問(wen)題。
