不合格電(dian)(dian)線電(dian)(dian)纜的危(wei)害

電(dian)(dian)線電(dian)(dian)纜(lan)是用于(yu)傳輸(shu)電(dian)(dian)力(li)、傳輸(shu)信息和實現(xian)電(dian)(dian)磁能量轉換的一大類電(dian)(dian)工產品(pin)。在抽查過(guo)程(cheng)中，發現(xian)了(le)大量的不合格產品(pin)，這(zhe)些劣(lie)質產品(pin)給電(dian)(dian)力(li)系統正常運(yun)行埋下諸(zhu)多隱患。

1、標(biao)志(zhi)不合格(ge)的(de)電(dian)(dian)線電(dian)(dian)纜。標(biao)志(zhi)是電(dian)(dian)線電(dian)(dian)纜使用識別產品(pin)基本(ben)信息的(de)主要(yao)途(tu)徑，根據標(biao)準(zhun)規定標(biao)志(zhi)的(de)主要(yao)內容是：產品(pin)型(xing)號、規格(ge)、標(biao)準(zhun)號、廠名(ming)、產地等在一定的(de)標(biao)示間距內，當標(biao)志(zhi)不合格(ge)時，會造成施工人員識別錯誤，嚴重時會引發(fa)電(dian)(dian)氣(qi)事故。

2、結(jie)(jie)構尺寸不合格的電(dian)(dian)(dian)線(xian)(xian)電(dian)(dian)(dian)纜(lan)。結(jie)(jie)構尺寸的主要問題(ti)是護(hu)套厚(hou)度(du)(du)，絕(jue)緣(yuan)(yuan)厚(hou)度(du)(du)，當電(dian)(dian)(dian)纜(lan)的護(hu)套和絕(jue)緣(yuan)(yuan)厚(hou)度(du)(du)不達標時(shi)，致使電(dian)(dian)(dian)線(xian)(xian)電(dian)(dian)(dian)纜(lan)耐電(dian)(dian)(dian)氣強度(du)(du)會嚴(yan)重(zhong)降低，導(dao)致電(dian)(dian)(dian)線(xian)(xian)電(dian)(dian)(dian)纜(lan)的使用壽命(ming)縮(suo)短，嚴(yan)重(zhong)時(shi)可導(dao)致電(dian)(dian)(dian)線(xian)(xian)電(dian)(dian)(dian)纜(lan)被擊(ji)穿，絕(jue)緣(yuan)(yuan)（護(hu)套）層起不到(dao)正(zheng)常保護(hu)作用，從而發生電(dian)(dian)(dian)氣短路和火災等現象。

3、護套(tao)式(shi)(shi)絕(jue)緣老(lao)化前的抗(kang)張(zhang)強(qiang)度、伸長(chang)率合格的電(dian)(dian)線(xian)電(dian)(dian)纜。絕(jue)緣護套(tao)老(lao)化前的抗(kang)張(zhang)強(qiang)度、伸長(chang)率不(bu)合格直接大大縮短電(dian)(dian)線(xian)電(dian)(dian)纜的工作用壽(shou)命，而且在(zai)施工或在(zai)長(chang)時間通電(dian)(dian)且溫(wen)度較高的環境中(zhong)，極易出現絕(jue)緣體(ti)斷(duan)裂(lie)，致使(shi)(shi)帶電(dian)(dian)導體(ti)裸(luo)露，發生(sheng)(sheng)能(neng)觸電(dian)(dian)式(shi)(shi)短路危險。其(qi)不(bu)合格的主要原因是使(shi)(shi)用了再生(sheng)(sheng)料生(sheng)(sheng)產，以(yi)降(jiang)低產品成(cheng)本，二是不(bu)具備生(sheng)(sheng)產資格小型企(qi)業。

4、導體(ti)(ti)電(dian)(dian)阻(zu)不合(he)格的(de)電(dian)(dian)線(xian)(xian)。導體(ti)(ti)電(dian)(dian)阻(zu)主(zhu)要是考(kao)核電(dian)(dian)線(xian)(xian)電(dian)(dian)纜的(de)導體(ti)(ti)材(cai)(cai)料以及截面(mian)是否符(fu)合(he)的(de)重要指標。當導體(ti)(ti)電(dian)(dian)阻(zu)超(chao)標時，就增大(da)了(le)(le)電(dian)(dian)流在線(xian)(xian)路上通過時的(de)損耗，加(jia)劇了(le)(le)電(dian)(dian)線(xian)(xian)電(dian)(dian)纜的(de)發熱。導體(ti)(ti)電(dian)(dian)阻(zu)不合(he)格的(de)原(yuan)因，主(zhu)要進企業(ye)為(wei)了(le)(le)降低成本(ben)，將占原(yuan)材(cai)(cai)料成本(ben)80%的(de)銅材(cai)(cai)縮水，要么降低導體(ti)(ti)的(de)截面(mian)積，要么使用含雜質過高的(de)再生銅，這樣致使電(dian)(dian)線(xian)(xian)電(dian)(dian)纜的(de)導體(ti)(ti)電(dian)(dian)阻(zu)嚴重超(chao)標，在使用過程中(zhong)除易引發火災，還會加(jia)速包覆在電(dian)(dian)線(xian)(xian)外的(de)絕緣層的(de)老(lao)化。

在(zai)購買電線電纜的過(guo)程中，消費者應注(zhu)意以下幾個事

第(di)一、要觀(guan)察電(dian)線的外觀(guan)。合(he)格產品(pin)的絕緣（護套）層柔軟、有韌性(xing)和(he)伸縮性(xing)、表(biao)面層緊(jin)密(mi)、光滑(hua)、無粗糙感。如(ru)果包裹(guo)電(dian)線的塑料(liao)很容(rong)易(yi)被(bei)剝(bo)去，則存(cun)在(zai)塑料(liao)強度(du)不夠的問題。

第二、要看電線的(de)(de)截面。合格產品(pin)的(de)(de)銅芯或(huo)鋁芯表(biao)面應(ying)該具(ju)有金屬光澤(ze)，表(biao)面發(fa)(fa)黑的(de)(de)銅或(huo)表(biao)面發(fa)(fa)白的(de)(de)鋁說明已被氧化(hua)。

第三(san)、在購買電線時應注(zhu)意查(cha)看質(zhi)(zhi)量(liang)合格證書。如果電線的(de)質(zhi)(zhi)量(liang)合格，那么(me)其電線質(zhi)(zhi)量(liang)應該也受過檢(jian)驗，不會有太大的(de)問題。
