不合(he)格電(dian)線電(dian)纜的危害(hai)

電(dian)(dian)線(xian)電(dian)(dian)纜是用(yong)于傳輸電(dian)(dian)力、傳輸信(xin)息(xi)和實現(xian)電(dian)(dian)磁能量轉換的(de)一大(da)類電(dian)(dian)工產品(pin)。在抽查(cha)過程中，發現(xian)了(le)大(da)量的(de)不合(he)格產品(pin)，這些劣質產品(pin)給電(dian)(dian)力系統正(zheng)常運(yun)行埋下諸多隱患。

1、標(biao)(biao)(biao)志(zhi)不合格(ge)(ge)的(de)電(dian)線電(dian)纜(lan)(lan)。標(biao)(biao)(biao)志(zhi)是電(dian)線電(dian)纜(lan)(lan)使(shi)用(yong)識別(bie)產(chan)品基(ji)本信息(xi)的(de)主要途徑，根據(ju)標(biao)(biao)(biao)準規定(ding)標(biao)(biao)(biao)志(zhi)的(de)主要內容是：產(chan)品型(xing)號、規格(ge)(ge)、標(biao)(biao)(biao)準號、廠名、產(chan)地等在一定(ding)的(de)標(biao)(biao)(biao)示間距內，當(dang)標(biao)(biao)(biao)志(zhi)不合格(ge)(ge)時，會造成施工人員識別(bie)錯誤，嚴重時會引發電(dian)氣事故(gu)。

2、結構(gou)尺寸不合格的(de)(de)電(dian)線(xian)電(dian)纜(lan)。結構(gou)尺寸的(de)(de)主要問題(ti)是護(hu)套(tao)厚度(du)，絕(jue)緣(yuan)厚度(du)，當(dang)電(dian)纜(lan)的(de)(de)護(hu)套(tao)和(he)絕(jue)緣(yuan)厚度(du)不達標時，致(zhi)使電(dian)線(xian)電(dian)纜(lan)耐電(dian)氣強度(du)會嚴(yan)重降低，導致(zhi)電(dian)線(xian)電(dian)纜(lan)的(de)(de)使用壽(shou)命縮短，嚴(yan)重時可導致(zhi)電(dian)線(xian)電(dian)纜(lan)被(bei)擊穿(chuan)，絕(jue)緣(yuan)（護(hu)套(tao)）層起不到正(zheng)常保護(hu)作用，從而發生(sheng)電(dian)氣短路(lu)和(he)火(huo)災等現象。

3、護(hu)套式絕(jue)緣(yuan)(yuan)老化前的(de)(de)抗張強(qiang)度、伸(shen)長(chang)率合(he)格(ge)(ge)的(de)(de)電(dian)線電(dian)纜。絕(jue)緣(yuan)(yuan)護(hu)套老化前的(de)(de)抗張強(qiang)度、伸(shen)長(chang)率不合(he)格(ge)(ge)直接大(da)大(da)縮短電(dian)線電(dian)纜的(de)(de)工(gong)作用壽命，而且(qie)在施工(gong)或(huo)在長(chang)時間(jian)通電(dian)且(qie)溫度較高的(de)(de)環境(jing)中(zhong)，極易出(chu)現絕(jue)緣(yuan)(yuan)體(ti)斷(duan)裂，致使(shi)帶電(dian)導體(ti)裸(luo)露，發生能(neng)觸電(dian)式短路(lu)危險。其不合(he)格(ge)(ge)的(de)(de)主要原因是使(shi)用了再(zai)生料(liao)生產，以(yi)降低產品成本，二是不具備生產資格(ge)(ge)小型企(qi)業。

4、導(dao)(dao)體電(dian)(dian)(dian)(dian)(dian)阻(zu)不合格(ge)的(de)(de)電(dian)(dian)(dian)(dian)(dian)線。導(dao)(dao)體電(dian)(dian)(dian)(dian)(dian)阻(zu)主要(yao)是(shi)考核(he)電(dian)(dian)(dian)(dian)(dian)線電(dian)(dian)(dian)(dian)(dian)纜的(de)(de)導(dao)(dao)體材料以及(ji)截(jie)面是(shi)否符合的(de)(de)重要(yao)指標(biao)(biao)。當導(dao)(dao)體電(dian)(dian)(dian)(dian)(dian)阻(zu)超標(biao)(biao)時，就增大(da)了(le)電(dian)(dian)(dian)(dian)(dian)流在線路上通(tong)過時的(de)(de)損耗，加劇了(le)電(dian)(dian)(dian)(dian)(dian)線電(dian)(dian)(dian)(dian)(dian)纜的(de)(de)發(fa)熱。導(dao)(dao)體電(dian)(dian)(dian)(dian)(dian)阻(zu)不合格(ge)的(de)(de)原(yuan)因，主要(yao)進企業(ye)為了(le)降(jiang)低成(cheng)(cheng)本，將占原(yuan)材料成(cheng)(cheng)本80%的(de)(de)銅材縮(suo)水(shui)，要(yao)么(me)降(jiang)低導(dao)(dao)體的(de)(de)截(jie)面積，要(yao)么(me)使(shi)(shi)用(yong)含(han)雜(za)質(zhi)過高(gao)的(de)(de)再生銅，這樣致使(shi)(shi)電(dian)(dian)(dian)(dian)(dian)線電(dian)(dian)(dian)(dian)(dian)纜的(de)(de)導(dao)(dao)體電(dian)(dian)(dian)(dian)(dian)阻(zu)嚴重超標(biao)(biao)，在使(shi)(shi)用(yong)過程中除(chu)易引發(fa)火災，還(huan)會加速包覆在電(dian)(dian)(dian)(dian)(dian)線外的(de)(de)絕緣層的(de)(de)老化。

在購(gou)買電線電纜的過(guo)程中，消(xiao)費(fei)者應注意以下幾個(ge)事

第一、要觀察電線(xian)的(de)外觀。合格產品(pin)的(de)絕(jue)緣（護(hu)套）層柔軟、有韌性和伸縮性、表面層緊(jin)密(mi)、光(guang)滑、無粗糙感。如果包裹電線(xian)的(de)塑料很容易被剝(bo)去(qu)，則(ze)存(cun)在塑料強度(du)不夠的(de)問題。

第二、要看電線的截面(mian)(mian)。合(he)格(ge)產品的銅芯或鋁芯表(biao)面(mian)(mian)應該具(ju)有金屬光(guang)澤，表(biao)面(mian)(mian)發黑的銅或表(biao)面(mian)(mian)發白的鋁說明已被氧化(hua)。

第三(san)、在購買電(dian)線時應注意查看(kan)質(zhi)量合格(ge)證書。如(ru)果電(dian)線的質(zhi)量合格(ge)，那么(me)其電(dian)線質(zhi)量應該也受(shou)過(guo)檢(jian)驗，不會有太大(da)的問題。
