不合格電線(xian)電纜的危害(hai)

電(dian)(dian)(dian)線電(dian)(dian)(dian)纜(lan)是用于傳(chuan)輸電(dian)(dian)(dian)力、傳(chuan)輸信息和實現電(dian)(dian)(dian)磁能量(liang)轉換的(de)(de)一大(da)類電(dian)(dian)(dian)工產(chan)品。在(zai)抽查過(guo)程中(zhong)，發現了(le)大(da)量(liang)的(de)(de)不合(he)格產(chan)品，這些(xie)劣質產(chan)品給電(dian)(dian)(dian)力系(xi)統正常運行埋下(xia)諸多隱患(huan)。

1、標志(zhi)不合(he)格(ge)的(de)電(dian)(dian)線電(dian)(dian)纜(lan)。標志(zhi)是電(dian)(dian)線電(dian)(dian)纜(lan)使(shi)用識別產品(pin)基(ji)本(ben)信息的(de)主要途徑(jing)，根據標準規(gui)(gui)定標志(zhi)的(de)主要內容是：產品(pin)型號、規(gui)(gui)格(ge)、標準號、廠名、產地(di)等在(zai)一定的(de)標示(shi)間距內，當標志(zhi)不合(he)格(ge)時，會造成施(shi)工人員識別錯誤(wu)，嚴重時會引(yin)發電(dian)(dian)氣事故。

2、結構尺寸不合格的電(dian)(dian)線電(dian)(dian)纜(lan)(lan)。結構尺寸的主要問(wen)題是護(hu)套厚度，絕(jue)緣厚度，當(dang)電(dian)(dian)纜(lan)(lan)的護(hu)套和絕(jue)緣厚度不達標時，致(zhi)(zhi)使(shi)電(dian)(dian)線電(dian)(dian)纜(lan)(lan)耐電(dian)(dian)氣(qi)強度會嚴重降(jiang)低(di)，導致(zhi)(zhi)電(dian)(dian)線電(dian)(dian)纜(lan)(lan)的使(shi)用壽命縮短，嚴重時可導致(zhi)(zhi)電(dian)(dian)線電(dian)(dian)纜(lan)(lan)被擊穿，絕(jue)緣（護(hu)套）層(ceng)起不到正常保(bao)護(hu)作用，從而發生電(dian)(dian)氣(qi)短路和火(huo)災等現(xian)象。

3、護套(tao)(tao)式絕緣老化(hua)前的(de)抗張(zhang)強(qiang)度(du)(du)(du)、伸長率合(he)格(ge)(ge)(ge)的(de)電(dian)(dian)(dian)線電(dian)(dian)(dian)纜。絕緣護套(tao)(tao)老化(hua)前的(de)抗張(zhang)強(qiang)度(du)(du)(du)、伸長率不(bu)合(he)格(ge)(ge)(ge)直接(jie)大(da)大(da)縮(suo)短電(dian)(dian)(dian)線電(dian)(dian)(dian)纜的(de)工(gong)作用(yong)(yong)壽(shou)命，而且在(zai)施工(gong)或在(zai)長時間通電(dian)(dian)(dian)且溫(wen)度(du)(du)(du)較高(gao)的(de)環(huan)境中，極易出現絕緣體斷裂，致使(shi)帶電(dian)(dian)(dian)導體裸露，發生能觸電(dian)(dian)(dian)式短路(lu)危險。其不(bu)合(he)格(ge)(ge)(ge)的(de)主要原因是(shi)使(shi)用(yong)(yong)了再生料生產，以降低(di)產品成本，二(er)是(shi)不(bu)具備生產資格(ge)(ge)(ge)小型企業。

4、導(dao)體(ti)(ti)電(dian)(dian)(dian)(dian)阻(zu)不(bu)合格的(de)(de)電(dian)(dian)(dian)(dian)線(xian)(xian)。導(dao)體(ti)(ti)電(dian)(dian)(dian)(dian)阻(zu)主(zhu)要(yao)(yao)是考核電(dian)(dian)(dian)(dian)線(xian)(xian)電(dian)(dian)(dian)(dian)纜(lan)的(de)(de)導(dao)體(ti)(ti)材料以及截面(mian)(mian)是否符(fu)合的(de)(de)重(zhong)要(yao)(yao)指標。當導(dao)體(ti)(ti)電(dian)(dian)(dian)(dian)阻(zu)超(chao)標時，就增大了(le)電(dian)(dian)(dian)(dian)流在(zai)線(xian)(xian)路上通過時的(de)(de)損耗，加(jia)劇了(le)電(dian)(dian)(dian)(dian)線(xian)(xian)電(dian)(dian)(dian)(dian)纜(lan)的(de)(de)發(fa)熱(re)。導(dao)體(ti)(ti)電(dian)(dian)(dian)(dian)阻(zu)不(bu)合格的(de)(de)原因，主(zhu)要(yao)(yao)進企(qi)業為(wei)了(le)降低成本，將占原材料成本80%的(de)(de)銅材縮水，要(yao)(yao)么降低導(dao)體(ti)(ti)的(de)(de)截面(mian)(mian)積(ji)，要(yao)(yao)么使用含雜質過高(gao)的(de)(de)再生銅，這樣致使電(dian)(dian)(dian)(dian)線(xian)(xian)電(dian)(dian)(dian)(dian)纜(lan)的(de)(de)導(dao)體(ti)(ti)電(dian)(dian)(dian)(dian)阻(zu)嚴(yan)重(zhong)超(chao)標，在(zai)使用過程中除(chu)易(yi)引發(fa)火災，還會加(jia)速包覆在(zai)電(dian)(dian)(dian)(dian)線(xian)(xian)外(wai)的(de)(de)絕緣層的(de)(de)老(lao)化。

在購買電(dian)線(xian)電(dian)纜的過程中，消(xiao)費者(zhe)應注意(yi)以下幾個事

第一、要觀察電線的(de)外(wai)觀。合格產品的(de)絕緣（護套）層柔軟、有(you)韌性和伸縮性、表面(mian)層緊密、光滑、無(wu)粗(cu)糙感。如果包(bao)裹電線的(de)塑料很(hen)容易被剝去，則存在塑料強度不夠的(de)問(wen)題。

第二、要看電線(xian)的截面(mian)。合格產(chan)品的銅芯(xin)或鋁芯(xin)表(biao)面(mian)應該具有(you)金屬光澤，表(biao)面(mian)發黑的銅或表(biao)面(mian)發白的鋁說明(ming)已被氧化。

第三、在(zai)購買電線時應(ying)(ying)注意查(cha)看質(zhi)量合格證書。如果(guo)電線的(de)質(zhi)量合格，那么其(qi)電線質(zhi)量應(ying)(ying)該也受過檢驗(yan)，不會(hui)有太大的(de)問題。
