不合格電線電纜(lan)的危害

電(dian)(dian)線電(dian)(dian)纜(lan)是用(yong)于傳(chuan)輸電(dian)(dian)力、傳(chuan)輸信息和實現(xian)電(dian)(dian)磁(ci)能(neng)量(liang)轉換的一大類(lei)電(dian)(dian)工產品(pin)。在抽(chou)查過程中，發現(xian)了大量(liang)的不合格產品(pin)，這些劣質(zhi)產品(pin)給(gei)電(dian)(dian)力系(xi)統(tong)正常運(yun)行埋(mai)下諸多隱患。

1、標志不(bu)合格的電(dian)(dian)線電(dian)(dian)纜。標志是電(dian)(dian)線電(dian)(dian)纜使用識別產品基本信(xin)息的主(zhu)要途徑，根(gen)據標準規定標志的主(zhu)要內(nei)容是：產品型號、規格、標準號、廠名、產地等在(zai)一定的標示間距內(nei)，當標志不(bu)合格時，會造成施工人員識別錯(cuo)誤(wu)，嚴(yan)重(zhong)時會引發電(dian)(dian)氣事故(gu)。

2、結構尺(chi)寸(cun)不(bu)(bu)合格(ge)的電(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)纜(lan)。結構尺(chi)寸(cun)的主要問(wen)題(ti)是護(hu)套厚(hou)度(du)，絕緣厚(hou)度(du)，當電(dian)(dian)(dian)纜(lan)的護(hu)套和絕緣厚(hou)度(du)不(bu)(bu)達標時，致(zhi)(zhi)使(shi)電(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)纜(lan)耐(nai)電(dian)(dian)(dian)氣(qi)強(qiang)度(du)會嚴(yan)重降(jiang)低，導致(zhi)(zhi)電(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)纜(lan)的使(shi)用(yong)壽命(ming)縮(suo)短(duan)，嚴(yan)重時可(ke)導致(zhi)(zhi)電(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)纜(lan)被(bei)擊穿，絕緣（護(hu)套）層起不(bu)(bu)到正常保護(hu)作用(yong)，從而發(fa)生電(dian)(dian)(dian)氣(qi)短(duan)路(lu)和火災(zai)等現象。

3、護套式絕緣老化前的(de)抗張強度、伸長(chang)率合格(ge)的(de)電線電纜。絕緣護套老化前的(de)抗張強度、伸長(chang)率不合格(ge)直接大(da)大(da)縮(suo)短電線電纜的(de)工作(zuo)用壽(shou)命(ming)，而且在施工或在長(chang)時(shi)間通電且溫度較高的(de)環境中，極易出現絕緣體(ti)斷裂，致使帶電導體(ti)裸露(lu)，發生(sheng)(sheng)能觸電式短路危險。其(qi)不合格(ge)的(de)主要原因是使用了(le)再生(sheng)(sheng)料生(sheng)(sheng)產(chan)，以降低產(chan)品成本，二是不具備(bei)生(sheng)(sheng)產(chan)資(zi)格(ge)小(xiao)型(xing)企業。

4、導(dao)體(ti)電(dian)(dian)阻(zu)不(bu)合格的(de)(de)電(dian)(dian)線(xian)(xian)(xian)。導(dao)體(ti)電(dian)(dian)阻(zu)主要(yao)是(shi)考核電(dian)(dian)線(xian)(xian)(xian)電(dian)(dian)纜(lan)的(de)(de)導(dao)體(ti)材料以及截面是(shi)否符合的(de)(de)重要(yao)指標(biao)。當導(dao)體(ti)電(dian)(dian)阻(zu)超標(biao)時(shi)，就增(zeng)大了(le)電(dian)(dian)流在線(xian)(xian)(xian)路上通(tong)過時(shi)的(de)(de)損耗，加(jia)劇了(le)電(dian)(dian)線(xian)(xian)(xian)電(dian)(dian)纜(lan)的(de)(de)發(fa)熱。導(dao)體(ti)電(dian)(dian)阻(zu)不(bu)合格的(de)(de)原因(yin)，主要(yao)進(jin)企(qi)業為(wei)了(le)降(jiang)低成本(ben)，將占(zhan)原材料成本(ben)80%的(de)(de)銅材縮水，要(yao)么降(jiang)低導(dao)體(ti)的(de)(de)截面積，要(yao)么使(shi)用含雜質過高的(de)(de)再(zai)生(sheng)銅，這樣致使(shi)電(dian)(dian)線(xian)(xian)(xian)電(dian)(dian)纜(lan)的(de)(de)導(dao)體(ti)電(dian)(dian)阻(zu)嚴(yan)重超標(biao)，在使(shi)用過程中除(chu)易(yi)引發(fa)火(huo)災，還會加(jia)速包(bao)覆在電(dian)(dian)線(xian)(xian)(xian)外的(de)(de)絕緣層的(de)(de)老化。

在購買電(dian)線(xian)電(dian)纜的過程中，消費者(zhe)應注意以(yi)下幾(ji)個事

第(di)一、要觀(guan)察電(dian)線的(de)外觀(guan)。合(he)格(ge)產品的(de)絕緣（護套）層(ceng)柔軟(ruan)、有韌性和伸縮性、表面(mian)層(ceng)緊密、光滑、無(wu)粗糙感。如果包裹電(dian)線的(de)塑料(liao)很容易被(bei)剝(bo)去，則存在塑料(liao)強度不夠的(de)問題。

第(di)二、要看電線的截面。合格產品的銅(tong)芯或(huo)鋁芯表面應該具有(you)金屬光澤(ze)，表面發(fa)黑(hei)的銅(tong)或(huo)表面發(fa)白的鋁說明(ming)已被氧(yang)化。

第三、在(zai)購(gou)買電(dian)線(xian)(xian)時應注意查(cha)看質量合(he)格證書。如果電(dian)線(xian)(xian)的質量合(he)格，那么其(qi)電(dian)線(xian)(xian)質量應該也受過檢驗，不會有太大的問(wen)題(ti)。
