不合(he)格電線電纜的危害

電(dian)(dian)線電(dian)(dian)纜是用(yong)于傳輸電(dian)(dian)力(li)、傳輸信息和實現(xian)電(dian)(dian)磁能量(liang)轉換的一大(da)類(lei)電(dian)(dian)工產(chan)(chan)品(pin)。在抽查過程中(zhong)，發現(xian)了大(da)量(liang)的不合格產(chan)(chan)品(pin)，這些劣(lie)質產(chan)(chan)品(pin)給電(dian)(dian)力(li)系統正(zheng)常運(yun)行埋(mai)下(xia)諸多隱患。

1、標(biao)(biao)志(zhi)不合格(ge)的電(dian)(dian)線(xian)電(dian)(dian)纜。標(biao)(biao)志(zhi)是(shi)(shi)電(dian)(dian)線(xian)電(dian)(dian)纜使用識別產(chan)品基本信(xin)息的主要途徑，根據(ju)標(biao)(biao)準規定標(biao)(biao)志(zhi)的主要內容是(shi)(shi)：產(chan)品型號、規格(ge)、標(biao)(biao)準號、廠名、產(chan)地等在一定的標(biao)(biao)示間距內，當標(biao)(biao)志(zhi)不合格(ge)時(shi)(shi)，會造成施工人員識別錯誤，嚴重(zhong)時(shi)(shi)會引發電(dian)(dian)氣事故。

2、結構(gou)尺寸不(bu)合格的(de)電線(xian)電纜(lan)。結構(gou)尺寸的(de)主要問(wen)題是護(hu)(hu)套厚度，絕緣(yuan)厚度，當電纜(lan)的(de)護(hu)(hu)套和絕緣(yuan)厚度不(bu)達標時，致(zhi)使電線(xian)電纜(lan)耐電氣強度會嚴重降低，導(dao)致(zhi)電線(xian)電纜(lan)的(de)使用壽命(ming)縮短(duan)，嚴重時可導(dao)致(zhi)電線(xian)電纜(lan)被(bei)擊穿(chuan)，絕緣(yuan)（護(hu)(hu)套）層(ceng)起不(bu)到正常保(bao)護(hu)(hu)作用，從而發生電氣短(duan)路(lu)和火災(zai)等現象。

3、護套式(shi)絕(jue)緣老(lao)化前的(de)(de)抗張(zhang)強(qiang)度、伸長(chang)率合(he)格的(de)(de)電(dian)線電(dian)纜。絕(jue)緣護套老(lao)化前的(de)(de)抗張(zhang)強(qiang)度、伸長(chang)率不(bu)合(he)格直接大大縮短(duan)電(dian)線電(dian)纜的(de)(de)工(gong)作用壽命，而且(qie)在施工(gong)或在長(chang)時間(jian)通電(dian)且(qie)溫度較(jiao)高的(de)(de)環(huan)境中，極易出現(xian)絕(jue)緣體(ti)斷裂，致(zhi)使帶電(dian)導體(ti)裸(luo)露，發生能觸電(dian)式(shi)短(duan)路危(wei)險。其不(bu)合(he)格的(de)(de)主(zhu)要原因是使用了(le)再生料(liao)生產(chan)，以降(jiang)低(di)產(chan)品成本，二(er)是不(bu)具備生產(chan)資(zi)格小型企業。

4、導(dao)體(ti)(ti)電(dian)(dian)(dian)阻(zu)(zu)不(bu)(bu)合(he)格的(de)(de)(de)(de)電(dian)(dian)(dian)線(xian)。導(dao)體(ti)(ti)電(dian)(dian)(dian)阻(zu)(zu)主(zhu)要(yao)是(shi)(shi)考核電(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)纜的(de)(de)(de)(de)導(dao)體(ti)(ti)材料以及截(jie)面是(shi)(shi)否符合(he)的(de)(de)(de)(de)重(zhong)要(yao)指標。當導(dao)體(ti)(ti)電(dian)(dian)(dian)阻(zu)(zu)超標時，就增(zeng)大了(le)電(dian)(dian)(dian)流在線(xian)路上通過時的(de)(de)(de)(de)損耗，加劇了(le)電(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)纜的(de)(de)(de)(de)發(fa)熱。導(dao)體(ti)(ti)電(dian)(dian)(dian)阻(zu)(zu)不(bu)(bu)合(he)格的(de)(de)(de)(de)原(yuan)因，主(zhu)要(yao)進企業為了(le)降低(di)成本，將占原(yuan)材料成本80%的(de)(de)(de)(de)銅材縮水(shui)，要(yao)么降低(di)導(dao)體(ti)(ti)的(de)(de)(de)(de)截(jie)面積，要(yao)么使(shi)用含雜質過高的(de)(de)(de)(de)再(zai)生銅，這樣致使(shi)電(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)纜的(de)(de)(de)(de)導(dao)體(ti)(ti)電(dian)(dian)(dian)阻(zu)(zu)嚴重(zhong)超標，在使(shi)用過程中(zhong)除易引發(fa)火災，還會(hui)加速包覆在電(dian)(dian)(dian)線(xian)外的(de)(de)(de)(de)絕緣層的(de)(de)(de)(de)老化。

在(zai)購買電線(xian)電纜(lan)的過(guo)程中，消費者應(ying)注意(yi)以下幾個事(shi)

第一、要(yao)觀(guan)(guan)察電(dian)線(xian)的(de)外觀(guan)(guan)。合格(ge)產品的(de)絕緣(yuan)（護套）層柔軟、有韌性(xing)和伸縮性(xing)、表(biao)面層緊密、光滑、無粗糙感。如果包裹電(dian)線(xian)的(de)塑(su)料很容易(yi)被(bei)剝(bo)去，則存在(zai)塑(su)料強度不(bu)夠的(de)問題。

第二、要看電線(xian)的截面(mian)。合(he)格產(chan)品(pin)的銅(tong)(tong)芯(xin)或鋁(lv)芯(xin)表面(mian)應該具有金屬(shu)光澤，表面(mian)發(fa)黑的銅(tong)(tong)或表面(mian)發(fa)白的鋁(lv)說明已被氧化。

第三、在購買電線時(shi)應注意查(cha)看(kan)質量合格證書(shu)。如果電線的(de)質量合格，那么其電線質量應該也(ye)受過檢驗(yan)，不會有太大的(de)問題。
