不合格電線電纜(lan)的危害

電(dian)(dian)線電(dian)(dian)纜(lan)是用于傳輸電(dian)(dian)力、傳輸信息(xi)和(he)實(shi)現(xian)(xian)電(dian)(dian)磁能量轉換的一大(da)類電(dian)(dian)工產(chan)(chan)品。在抽查過程中(zhong)，發現(xian)(xian)了大(da)量的不合格(ge)產(chan)(chan)品，這些(xie)劣質產(chan)(chan)品給電(dian)(dian)力系統正常運行(xing)埋下諸多隱患。

1、標(biao)志不合格(ge)的電(dian)(dian)(dian)(dian)線電(dian)(dian)(dian)(dian)纜(lan)。標(biao)志是電(dian)(dian)(dian)(dian)線電(dian)(dian)(dian)(dian)纜(lan)使用識(shi)別(bie)產(chan)品基本信(xin)息的主(zhu)要途徑(jing)，根(gen)據(ju)標(biao)準(zhun)規(gui)定(ding)標(biao)志的主(zhu)要內(nei)容是：產(chan)品型號、規(gui)格(ge)、標(biao)準(zhun)號、廠名、產(chan)地等在一定(ding)的標(biao)示間距(ju)內(nei)，當標(biao)志不合格(ge)時，會(hui)(hui)造(zao)成施(shi)工(gong)人員識(shi)別(bie)錯誤，嚴重時會(hui)(hui)引發電(dian)(dian)(dian)(dian)氣(qi)事故。

2、結(jie)構尺(chi)寸不(bu)(bu)合格(ge)的(de)電(dian)線電(dian)纜(lan)。結(jie)構尺(chi)寸的(de)主要(yao)問題是護(hu)套(tao)厚度，絕(jue)(jue)緣厚度，當電(dian)纜(lan)的(de)護(hu)套(tao)和絕(jue)(jue)緣厚度不(bu)(bu)達標時，致使電(dian)線電(dian)纜(lan)耐電(dian)氣強度會嚴重(zhong)降低，導致電(dian)線電(dian)纜(lan)的(de)使用(yong)(yong)壽命(ming)縮短，嚴重(zhong)時可(ke)導致電(dian)線電(dian)纜(lan)被擊穿，絕(jue)(jue)緣（護(hu)套(tao)）層起不(bu)(bu)到正常保護(hu)作用(yong)(yong)，從(cong)而發(fa)生電(dian)氣短路和火災(zai)等現(xian)象(xiang)。

3、護套(tao)式絕(jue)緣老(lao)化(hua)前(qian)的抗(kang)張(zhang)強度(du)、伸長(chang)(chang)率(lv)合(he)格的電(dian)(dian)線(xian)電(dian)(dian)纜(lan)。絕(jue)緣護套(tao)老(lao)化(hua)前(qian)的抗(kang)張(zhang)強度(du)、伸長(chang)(chang)率(lv)不(bu)合(he)格直接大大縮短電(dian)(dian)線(xian)電(dian)(dian)纜(lan)的工(gong)(gong)作用壽命，而且(qie)在(zai)施工(gong)(gong)或(huo)在(zai)長(chang)(chang)時(shi)間通電(dian)(dian)且(qie)溫度(du)較高的環境中(zhong)，極易(yi)出現絕(jue)緣體斷裂，致使帶電(dian)(dian)導(dao)體裸露，發生(sheng)能觸電(dian)(dian)式短路危險。其不(bu)合(he)格的主要原(yuan)因是(shi)使用了再生(sheng)料生(sheng)產，以降低產品(pin)成本(ben)，二是(shi)不(bu)具備生(sheng)產資(zi)格小(xiao)型企(qi)業。

4、導(dao)體(ti)(ti)電(dian)(dian)(dian)阻(zu)不(bu)合格的(de)(de)(de)電(dian)(dian)(dian)線。導(dao)體(ti)(ti)電(dian)(dian)(dian)阻(zu)主要(yao)(yao)(yao)是考核電(dian)(dian)(dian)線電(dian)(dian)(dian)纜的(de)(de)(de)導(dao)體(ti)(ti)材(cai)料(liao)以及截面(mian)是否(fou)符合的(de)(de)(de)重要(yao)(yao)(yao)指標。當導(dao)體(ti)(ti)電(dian)(dian)(dian)阻(zu)超(chao)標時，就增大了(le)(le)電(dian)(dian)(dian)流(liu)在(zai)線路(lu)上通過(guo)時的(de)(de)(de)損耗，加(jia)劇(ju)了(le)(le)電(dian)(dian)(dian)線電(dian)(dian)(dian)纜的(de)(de)(de)發熱。導(dao)體(ti)(ti)電(dian)(dian)(dian)阻(zu)不(bu)合格的(de)(de)(de)原(yuan)因，主要(yao)(yao)(yao)進企業為了(le)(le)降低成(cheng)本，將占(zhan)原(yuan)材(cai)料(liao)成(cheng)本80%的(de)(de)(de)銅(tong)材(cai)縮水，要(yao)(yao)(yao)么降低導(dao)體(ti)(ti)的(de)(de)(de)截面(mian)積，要(yao)(yao)(yao)么使用含(han)雜質過(guo)高的(de)(de)(de)再生銅(tong)，這樣致使電(dian)(dian)(dian)線電(dian)(dian)(dian)纜的(de)(de)(de)導(dao)體(ti)(ti)電(dian)(dian)(dian)阻(zu)嚴重超(chao)標，在(zai)使用過(guo)程(cheng)中除易引發火災，還會加(jia)速包覆在(zai)電(dian)(dian)(dian)線外的(de)(de)(de)絕緣層(ceng)的(de)(de)(de)老化。

在購買電(dian)線電(dian)纜的過程中，消費(fei)者應注(zhu)意以下幾(ji)個(ge)事

第一、要(yao)觀(guan)察電線的外觀(guan)。合格產品的絕(jue)緣（護(hu)套(tao)）層柔(rou)軟、有(you)韌性和伸縮性、表(biao)面層緊密、光滑(hua)、無粗糙感。如(ru)果包裹電線的塑料(liao)(liao)很容易被剝去(qu)，則存(cun)在塑料(liao)(liao)強度不夠的問題。

第(di)二(er)、要看電線的(de)截面。合格(ge)產品的(de)銅(tong)芯或鋁芯表(biao)(biao)面應該具有金屬光(guang)澤(ze)，表(biao)(biao)面發黑的(de)銅(tong)或表(biao)(biao)面發白的(de)鋁說明(ming)已被氧化。

第三、在購買電(dian)線時應注意(yi)查看質(zhi)量(liang)合(he)格(ge)證書。如果電(dian)線的(de)質(zhi)量(liang)合(he)格(ge)，那么其電(dian)線質(zhi)量(liang)應該(gai)也受過檢驗，不會有(you)太(tai)大的(de)問(wen)題。
