不合(he)格電(dian)線電(dian)纜的危(wei)害

電(dian)線電(dian)纜是(shi)用于傳輸(shu)(shu)電(dian)力(li)、傳輸(shu)(shu)信息和實現電(dian)磁(ci)能量轉換的一大類電(dian)工產品。在抽查過程中，發(fa)現了(le)大量的不合(he)格(ge)產品，這些劣質產品給(gei)電(dian)力(li)系統正常運行埋下諸多隱(yin)患。

1、標志(zhi)不(bu)合(he)格(ge)的(de)電線(xian)電纜(lan)。標志(zhi)是電線(xian)電纜(lan)使用識別產(chan)品基本信息的(de)主要(yao)途徑，根據標準(zhun)(zhun)規(gui)定(ding)(ding)標志(zhi)的(de)主要(yao)內容(rong)是：產(chan)品型(xing)號(hao)、規(gui)格(ge)、標準(zhun)(zhun)號(hao)、廠名(ming)、產(chan)地等在一(yi)定(ding)(ding)的(de)標示間距內，當標志(zhi)不(bu)合(he)格(ge)時(shi)，會造(zao)成施工人員識別錯(cuo)誤，嚴重時(shi)會引發(fa)電氣事故。

2、結(jie)構(gou)尺寸不合格的電(dian)(dian)(dian)(dian)線(xian)(xian)電(dian)(dian)(dian)(dian)纜。結(jie)構(gou)尺寸的主要問題是(shi)護(hu)套厚度(du)(du)，絕緣厚度(du)(du)，當電(dian)(dian)(dian)(dian)纜的護(hu)套和(he)(he)絕緣厚度(du)(du)不達標時，致(zhi)使電(dian)(dian)(dian)(dian)線(xian)(xian)電(dian)(dian)(dian)(dian)纜耐電(dian)(dian)(dian)(dian)氣強度(du)(du)會嚴重降低(di)，導(dao)致(zhi)電(dian)(dian)(dian)(dian)線(xian)(xian)電(dian)(dian)(dian)(dian)纜的使用壽命縮短(duan)，嚴重時可導(dao)致(zhi)電(dian)(dian)(dian)(dian)線(xian)(xian)電(dian)(dian)(dian)(dian)纜被(bei)擊穿，絕緣（護(hu)套）層起不到正常保護(hu)作用，從而發生電(dian)(dian)(dian)(dian)氣短(duan)路和(he)(he)火災等現象(xiang)。

3、護套式絕(jue)緣(yuan)老化(hua)前(qian)的(de)抗張(zhang)強度、伸長(chang)率合格(ge)的(de)電(dian)(dian)(dian)(dian)線電(dian)(dian)(dian)(dian)纜。絕(jue)緣(yuan)護套老化(hua)前(qian)的(de)抗張(zhang)強度、伸長(chang)率不(bu)合格(ge)直接大(da)大(da)縮短電(dian)(dian)(dian)(dian)線電(dian)(dian)(dian)(dian)纜的(de)工作用(yong)(yong)壽命，而且在施工或在長(chang)時間通電(dian)(dian)(dian)(dian)且溫度較高(gao)的(de)環(huan)境中(zhong)，極易出現(xian)絕(jue)緣(yuan)體斷裂，致使帶(dai)電(dian)(dian)(dian)(dian)導體裸露，發(fa)生能觸(chu)電(dian)(dian)(dian)(dian)式短路危險(xian)。其不(bu)合格(ge)的(de)主要原因是使用(yong)(yong)了再生料生產(chan)(chan)，以降低產(chan)(chan)品成本，二(er)是不(bu)具備生產(chan)(chan)資格(ge)小型企業。

4、導(dao)體(ti)電(dian)阻(zu)(zu)不合格的(de)電(dian)線(xian)。導(dao)體(ti)電(dian)阻(zu)(zu)主(zhu)要(yao)是考核電(dian)線(xian)電(dian)纜(lan)的(de)導(dao)體(ti)材料(liao)以及截(jie)面(mian)是否符合的(de)重要(yao)指標(biao)(biao)(biao)。當導(dao)體(ti)電(dian)阻(zu)(zu)超標(biao)(biao)(biao)時，就增大(da)了(le)(le)(le)電(dian)流在(zai)線(xian)路(lu)上通過(guo)時的(de)損耗(hao)，加劇(ju)了(le)(le)(le)電(dian)線(xian)電(dian)纜(lan)的(de)發熱(re)。導(dao)體(ti)電(dian)阻(zu)(zu)不合格的(de)原(yuan)因(yin)，主(zhu)要(yao)進企業為了(le)(le)(le)降(jiang)低成本(ben)，將占原(yuan)材料(liao)成本(ben)80%的(de)銅材縮水，要(yao)么(me)降(jiang)低導(dao)體(ti)的(de)截(jie)面(mian)積，要(yao)么(me)使(shi)用含雜質過(guo)高的(de)再生銅，這樣致使(shi)電(dian)線(xian)電(dian)纜(lan)的(de)導(dao)體(ti)電(dian)阻(zu)(zu)嚴(yan)重超標(biao)(biao)(biao)，在(zai)使(shi)用過(guo)程中除(chu)易引發火災，還會加速包覆在(zai)電(dian)線(xian)外的(de)絕(jue)緣層的(de)老化。

在購買(mai)電(dian)線電(dian)纜的過程中，消費者應注意以下幾個事(shi)

第(di)一、要觀(guan)察電線(xian)的外觀(guan)。合格產(chan)品(pin)的絕緣（護套）層柔軟、有韌性和伸縮性、表面(mian)層緊密、光滑、無(wu)粗糙感(gan)。如(ru)果包裹電線(xian)的塑(su)料(liao)很(hen)容易被(bei)剝去，則存在塑(su)料(liao)強(qiang)度不夠的問(wen)題。

第二、要看電線的截面。合格產品的銅芯或鋁(lv)芯表面應該具有(you)金屬光(guang)澤，表面發黑(hei)的銅或表面發白的鋁(lv)說明已被氧化。

第三(san)、在(zai)購買(mai)電線(xian)(xian)時應(ying)注意查看質量(liang)合格證(zheng)書。如果電線(xian)(xian)的(de)質量(liang)合格，那么(me)其電線(xian)(xian)質量(liang)應(ying)該也受過(guo)檢(jian)驗，不會有太大的(de)問題。
