不合格電(dian)(dian)線電(dian)(dian)纜(lan)的危害

電(dian)線(xian)電(dian)纜是用于傳輸電(dian)力、傳輸信息和實現電(dian)磁能量轉換(huan)的(de)一(yi)大類電(dian)工產(chan)品(pin)。在抽(chou)查過程中(zhong)，發現了大量的(de)不合格產(chan)品(pin)，這些劣質產(chan)品(pin)給電(dian)力系統正常運行埋下諸多隱患(huan)。

1、標(biao)(biao)(biao)志不合(he)格的電(dian)(dian)(dian)線(xian)(xian)電(dian)(dian)(dian)纜。標(biao)(biao)(biao)志是(shi)(shi)電(dian)(dian)(dian)線(xian)(xian)電(dian)(dian)(dian)纜使用識別(bie)產品基本(ben)信息(xi)的主要途徑，根(gen)據(ju)標(biao)(biao)(biao)準規定標(biao)(biao)(biao)志的主要內容是(shi)(shi)：產品型號、規格、標(biao)(biao)(biao)準號、廠名、產地等在一(yi)定的標(biao)(biao)(biao)示間距(ju)內，當標(biao)(biao)(biao)志不合(he)格時，會造(zao)成(cheng)施工(gong)人員識別(bie)錯誤，嚴重時會引發電(dian)(dian)(dian)氣事故。

2、結(jie)構尺(chi)寸(cun)不(bu)(bu)合格的(de)電(dian)線電(dian)纜(lan)。結(jie)構尺(chi)寸(cun)的(de)主要(yao)問題是護套(tao)厚(hou)度(du)，絕(jue)緣(yuan)厚(hou)度(du)，當電(dian)纜(lan)的(de)護套(tao)和絕(jue)緣(yuan)厚(hou)度(du)不(bu)(bu)達標時，致使(shi)電(dian)線電(dian)纜(lan)耐電(dian)氣(qi)強度(du)會嚴(yan)(yan)重(zhong)降低，導致電(dian)線電(dian)纜(lan)的(de)使(shi)用壽命縮短(duan)，嚴(yan)(yan)重(zhong)時可導致電(dian)線電(dian)纜(lan)被擊穿(chuan)，絕(jue)緣(yuan)（護套(tao)）層(ceng)起不(bu)(bu)到正常保護作用，從而(er)發生電(dian)氣(qi)短(duan)路(lu)和火災等(deng)現象(xiang)。

3、護套式絕緣(yuan)老(lao)化(hua)(hua)前的(de)(de)(de)抗張強度(du)、伸長(chang)率(lv)合格的(de)(de)(de)電(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)纜(lan)。絕緣(yuan)護套老(lao)化(hua)(hua)前的(de)(de)(de)抗張強度(du)、伸長(chang)率(lv)不合格直接大大縮短(duan)電(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)纜(lan)的(de)(de)(de)工(gong)作(zuo)用壽命，而且(qie)在施工(gong)或在長(chang)時間通電(dian)(dian)(dian)且(qie)溫度(du)較高(gao)的(de)(de)(de)環(huan)境(jing)中，極易出(chu)現絕緣(yuan)體(ti)斷裂，致使帶電(dian)(dian)(dian)導體(ti)裸(luo)露，發生(sheng)(sheng)能觸電(dian)(dian)(dian)式短(duan)路危險(xian)。其不合格的(de)(de)(de)主要原因是使用了再生(sheng)(sheng)料(liao)生(sheng)(sheng)產，以降低產品成本，二是不具備生(sheng)(sheng)產資格小型企業。

4、導(dao)體電(dian)(dian)(dian)阻(zu)(zu)不合格(ge)的(de)(de)(de)(de)(de)電(dian)(dian)(dian)線(xian)。導(dao)體電(dian)(dian)(dian)阻(zu)(zu)主要是考核電(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)纜的(de)(de)(de)(de)(de)導(dao)體材料以及截(jie)面是否符合的(de)(de)(de)(de)(de)重要指標。當導(dao)體電(dian)(dian)(dian)阻(zu)(zu)超(chao)標時，就增大了電(dian)(dian)(dian)流在線(xian)路上通過時的(de)(de)(de)(de)(de)損耗，加(jia)劇了電(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)纜的(de)(de)(de)(de)(de)發熱。導(dao)體電(dian)(dian)(dian)阻(zu)(zu)不合格(ge)的(de)(de)(de)(de)(de)原(yuan)(yuan)因，主要進企業(ye)為了降低成(cheng)本(ben)(ben)，將占原(yuan)(yuan)材料成(cheng)本(ben)(ben)80%的(de)(de)(de)(de)(de)銅材縮水，要么(me)(me)降低導(dao)體的(de)(de)(de)(de)(de)截(jie)面積(ji)，要么(me)(me)使用含(han)雜質過高的(de)(de)(de)(de)(de)再生(sheng)銅，這樣致使電(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)纜的(de)(de)(de)(de)(de)導(dao)體電(dian)(dian)(dian)阻(zu)(zu)嚴(yan)重超(chao)標，在使用過程中除(chu)易引發火災，還會(hui)加(jia)速(su)包覆(fu)在電(dian)(dian)(dian)線(xian)外的(de)(de)(de)(de)(de)絕緣層的(de)(de)(de)(de)(de)老化。

在購買電線電纜(lan)的過程中，消費者應注意以下幾(ji)個事(shi)

第(di)一(yi)、要觀察電(dian)線的(de)外觀。合格產品的(de)絕(jue)緣（護套）層柔(rou)軟(ruan)、有韌性(xing)和伸縮性(xing)、表面層緊(jin)密(mi)、光滑、無粗糙(cao)感。如果包(bao)裹電(dian)線的(de)塑料很(hen)容易被(bei)剝去，則存在塑料強(qiang)度不夠的(de)問題。

第二、要看電線的截面(mian)。合格產品的銅芯或(huo)鋁(lv)芯表(biao)面(mian)應該具有金屬光澤，表(biao)面(mian)發黑的銅或(huo)表(biao)面(mian)發白的鋁(lv)說明(ming)已被氧化。

第三、在(zai)購買(mai)電(dian)線時應(ying)注意(yi)查看(kan)質(zhi)量合格(ge)證(zheng)書。如果電(dian)線的(de)質(zhi)量合格(ge)，那(nei)么其(qi)電(dian)線質(zhi)量應(ying)該(gai)也(ye)受過(guo)檢驗，不(bu)會有(you)太大的(de)問題。
