不(bu)合格(ge)電(dian)線電(dian)纜的危害

電(dian)線電(dian)纜是(shi)用于傳輸電(dian)力、傳輸信息和實現(xian)(xian)電(dian)磁能量轉換的(de)(de)一大(da)類(lei)電(dian)工產(chan)品(pin)(pin)。在抽查過(guo)程中，發現(xian)(xian)了大(da)量的(de)(de)不合格產(chan)品(pin)(pin)，這些劣質產(chan)品(pin)(pin)給(gei)電(dian)力系統正常(chang)運行埋下諸多(duo)隱患。

1、標志不合格(ge)的(de)電(dian)線電(dian)纜。標志是(shi)電(dian)線電(dian)纜使(shi)用識別(bie)產品基(ji)本信息(xi)的(de)主要途徑，根據標準規定標志的(de)主要內容是(shi)：產品型號、規格(ge)、標準號、廠名、產地等在一定的(de)標示(shi)間距(ju)內，當(dang)標志不合格(ge)時，會造成施工人員識別(bie)錯誤，嚴重時會引(yin)發電(dian)氣事故。

2、結構尺寸(cun)不合格的電(dian)(dian)線電(dian)(dian)纜。結構尺寸(cun)的主要問(wen)題是護(hu)套(tao)厚(hou)(hou)度(du)，絕(jue)緣厚(hou)(hou)度(du)，當電(dian)(dian)纜的護(hu)套(tao)和(he)絕(jue)緣厚(hou)(hou)度(du)不達(da)標時，致(zhi)使(shi)(shi)電(dian)(dian)線電(dian)(dian)纜耐(nai)電(dian)(dian)氣強度(du)會嚴(yan)重降低(di)，導(dao)致(zhi)電(dian)(dian)線電(dian)(dian)纜的使(shi)(shi)用壽命縮(suo)短(duan)，嚴(yan)重時可導(dao)致(zhi)電(dian)(dian)線電(dian)(dian)纜被(bei)擊穿(chuan)，絕(jue)緣（護(hu)套(tao)）層起不到正常保護(hu)作(zuo)用，從而發生(sheng)電(dian)(dian)氣短(duan)路和(he)火災等現象。

3、護(hu)套式絕緣老化前的(de)抗張(zhang)強度(du)、伸長(chang)率(lv)合(he)格的(de)電(dian)線(xian)電(dian)纜。絕緣護(hu)套老化前的(de)抗張(zhang)強度(du)、伸長(chang)率(lv)不(bu)合(he)格直接大大縮短(duan)電(dian)線(xian)電(dian)纜的(de)工(gong)作用壽(shou)命，而且在施工(gong)或在長(chang)時(shi)間通電(dian)且溫度(du)較高的(de)環境中(zhong)，極易出現絕緣體斷裂，致使帶(dai)電(dian)導體裸(luo)露，發生(sheng)能觸電(dian)式短(duan)路(lu)危險。其(qi)不(bu)合(he)格的(de)主要(yao)原因是使用了再生(sheng)料生(sheng)產，以降低產品成本，二是不(bu)具備生(sheng)產資格小(xiao)型企業(ye)。

4、導體(ti)電(dian)(dian)(dian)(dian)阻不(bu)合(he)格的(de)(de)(de)電(dian)(dian)(dian)(dian)線(xian)(xian)(xian)。導體(ti)電(dian)(dian)(dian)(dian)阻主要(yao)是考核電(dian)(dian)(dian)(dian)線(xian)(xian)(xian)電(dian)(dian)(dian)(dian)纜(lan)(lan)的(de)(de)(de)導體(ti)材(cai)(cai)料以(yi)及截面是否符合(he)的(de)(de)(de)重要(yao)指標(biao)(biao)。當導體(ti)電(dian)(dian)(dian)(dian)阻超(chao)標(biao)(biao)時，就增(zeng)大了(le)電(dian)(dian)(dian)(dian)流在線(xian)(xian)(xian)路上通過時的(de)(de)(de)損(sun)耗(hao)，加劇了(le)電(dian)(dian)(dian)(dian)線(xian)(xian)(xian)電(dian)(dian)(dian)(dian)纜(lan)(lan)的(de)(de)(de)發熱。導體(ti)電(dian)(dian)(dian)(dian)阻不(bu)合(he)格的(de)(de)(de)原(yuan)因，主要(yao)進企(qi)業(ye)為(wei)了(le)降(jiang)低成(cheng)本，將占原(yuan)材(cai)(cai)料成(cheng)本80%的(de)(de)(de)銅(tong)材(cai)(cai)縮水(shui)，要(yao)么降(jiang)低導體(ti)的(de)(de)(de)截面積，要(yao)么使(shi)(shi)用含雜質過高的(de)(de)(de)再生銅(tong)，這樣致使(shi)(shi)電(dian)(dian)(dian)(dian)線(xian)(xian)(xian)電(dian)(dian)(dian)(dian)纜(lan)(lan)的(de)(de)(de)導體(ti)電(dian)(dian)(dian)(dian)阻嚴(yan)重超(chao)標(biao)(biao)，在使(shi)(shi)用過程中除(chu)易(yi)引發火災(zai)，還會(hui)加速包覆在電(dian)(dian)(dian)(dian)線(xian)(xian)(xian)外的(de)(de)(de)絕緣層的(de)(de)(de)老化(hua)。

在購買電線電纜的過程(cheng)中，消費(fei)者應注意以下(xia)幾個事(shi)

第一、要觀察電線的(de)(de)(de)外(wai)觀。合格產品的(de)(de)(de)絕緣(yuan)（護套）層柔軟(ruan)、有(you)韌性(xing)(xing)和(he)伸縮性(xing)(xing)、表面層緊(jin)密、光滑(hua)、無粗糙感。如(ru)果(guo)包(bao)裹電線的(de)(de)(de)塑料很容(rong)易被剝(bo)去，則存在塑料強度不(bu)夠的(de)(de)(de)問題。

第二(er)、要看電(dian)線的(de)(de)截面(mian)。合格產(chan)品的(de)(de)銅(tong)芯(xin)或(huo)鋁芯(xin)表(biao)面(mian)應該(gai)具有金(jin)屬光澤，表(biao)面(mian)發(fa)黑的(de)(de)銅(tong)或(huo)表(biao)面(mian)發(fa)白的(de)(de)鋁說明已被(bei)氧化。

第三、在購買電線時應注(zhu)意查看質量合(he)格(ge)證書。如果電線的質量合(he)格(ge)，那么其電線質量應該也(ye)受(shou)過檢驗，不會有太大的問題(ti)。
