不合格電線電纜的危(wei)害

電(dian)線電(dian)纜(lan)是用(yong)于(yu)傳輸電(dian)力(li)、傳輸信息(xi)和實現電(dian)磁能量轉換的一大(da)類電(dian)工(gong)產品(pin)。在(zai)抽查過程(cheng)中，發(fa)現了大(da)量的不合格產品(pin)，這(zhe)些(xie)劣質產品(pin)給電(dian)力(li)系統正常運行埋下諸多(duo)隱(yin)患。

1、標志(zhi)(zhi)不(bu)合(he)格的(de)電(dian)(dian)線(xian)電(dian)(dian)纜。標志(zhi)(zhi)是電(dian)(dian)線(xian)電(dian)(dian)纜使用識(shi)別產品基本信息(xi)的(de)主(zhu)要途(tu)徑，根(gen)據標準(zhun)規定標志(zhi)(zhi)的(de)主(zhu)要內(nei)容(rong)是：產品型(xing)號(hao)、規格、標準(zhun)號(hao)、廠(chang)名、產地(di)等在一定的(de)標示間(jian)距內(nei)，當標志(zhi)(zhi)不(bu)合(he)格時，會造成施(shi)工人員識(shi)別錯(cuo)誤，嚴(yan)重時會引發電(dian)(dian)氣事故。

2、結構(gou)尺寸(cun)不合格(ge)的電(dian)(dian)(dian)線(xian)(xian)電(dian)(dian)(dian)纜(lan)。結構(gou)尺寸(cun)的主要問題是護套(tao)厚度，絕緣(yuan)厚度，當電(dian)(dian)(dian)纜(lan)的護套(tao)和(he)(he)絕緣(yuan)厚度不達標時(shi)，致(zhi)使(shi)(shi)電(dian)(dian)(dian)線(xian)(xian)電(dian)(dian)(dian)纜(lan)耐電(dian)(dian)(dian)氣強度會(hui)嚴重(zhong)降低，導(dao)致(zhi)電(dian)(dian)(dian)線(xian)(xian)電(dian)(dian)(dian)纜(lan)的使(shi)(shi)用壽命縮短，嚴重(zhong)時(shi)可導(dao)致(zhi)電(dian)(dian)(dian)線(xian)(xian)電(dian)(dian)(dian)纜(lan)被擊穿，絕緣(yuan)（護套(tao)）層起不到正常保(bao)護作用，從而發(fa)生電(dian)(dian)(dian)氣短路和(he)(he)火災(zai)等現(xian)象。

3、護套(tao)(tao)式絕緣老化前的(de)抗(kang)張(zhang)強(qiang)度、伸(shen)長率合格(ge)(ge)的(de)電(dian)線(xian)電(dian)纜。絕緣護套(tao)(tao)老化前的(de)抗(kang)張(zhang)強(qiang)度、伸(shen)長率不(bu)合格(ge)(ge)直接大大縮(suo)短(duan)電(dian)線(xian)電(dian)纜的(de)工作用壽命，而且在(zai)施工或(huo)在(zai)長時間通電(dian)且溫度較高(gao)的(de)環境中，極易出現絕緣體(ti)(ti)斷裂，致使(shi)帶電(dian)導(dao)體(ti)(ti)裸(luo)露，發生(sheng)能觸電(dian)式短(duan)路(lu)危險。其不(bu)合格(ge)(ge)的(de)主要原因(yin)是(shi)使(shi)用了再生(sheng)料生(sheng)產，以降(jiang)低(di)產品成本，二是(shi)不(bu)具備生(sheng)產資格(ge)(ge)小型企業(ye)。

4、導(dao)體(ti)(ti)(ti)(ti)電(dian)(dian)(dian)(dian)阻(zu)不合格(ge)的(de)(de)(de)電(dian)(dian)(dian)(dian)線(xian)(xian)。導(dao)體(ti)(ti)(ti)(ti)電(dian)(dian)(dian)(dian)阻(zu)主(zhu)要是考(kao)核電(dian)(dian)(dian)(dian)線(xian)(xian)電(dian)(dian)(dian)(dian)纜的(de)(de)(de)導(dao)體(ti)(ti)(ti)(ti)材(cai)(cai)料以及截(jie)面是否符(fu)合的(de)(de)(de)重要指標(biao)。當導(dao)體(ti)(ti)(ti)(ti)電(dian)(dian)(dian)(dian)阻(zu)超(chao)標(biao)時，就增大(da)了電(dian)(dian)(dian)(dian)流在(zai)線(xian)(xian)路(lu)上通(tong)過(guo)(guo)時的(de)(de)(de)損耗，加劇了電(dian)(dian)(dian)(dian)線(xian)(xian)電(dian)(dian)(dian)(dian)纜的(de)(de)(de)發熱。導(dao)體(ti)(ti)(ti)(ti)電(dian)(dian)(dian)(dian)阻(zu)不合格(ge)的(de)(de)(de)原(yuan)因，主(zhu)要進企業為了降低(di)成(cheng)本(ben)，將占原(yuan)材(cai)(cai)料成(cheng)本(ben)80%的(de)(de)(de)銅(tong)材(cai)(cai)縮水(shui)，要么降低(di)導(dao)體(ti)(ti)(ti)(ti)的(de)(de)(de)截(jie)面積(ji)，要么使(shi)用(yong)含雜質過(guo)(guo)高(gao)的(de)(de)(de)再生銅(tong)，這(zhe)樣(yang)致使(shi)電(dian)(dian)(dian)(dian)線(xian)(xian)電(dian)(dian)(dian)(dian)纜的(de)(de)(de)導(dao)體(ti)(ti)(ti)(ti)電(dian)(dian)(dian)(dian)阻(zu)嚴重超(chao)標(biao)，在(zai)使(shi)用(yong)過(guo)(guo)程(cheng)中(zhong)除易引發火災，還會加速包覆在(zai)電(dian)(dian)(dian)(dian)線(xian)(xian)外的(de)(de)(de)絕緣層的(de)(de)(de)老化。

在購買電(dian)線電(dian)纜(lan)的過程中，消(xiao)費者(zhe)應注意以下(xia)幾(ji)個事

第一、要觀察電(dian)線的(de)外觀。合格產品(pin)的(de)絕緣（護套(tao)）層(ceng)柔軟、有韌(ren)性和伸(shen)縮性、表面(mian)層(ceng)緊(jin)密、光滑、無粗糙感(gan)。如果包裹電(dian)線的(de)塑(su)料(liao)很容易(yi)被剝去，則存在塑(su)料(liao)強度不夠的(de)問題。

第二、要看電線(xian)的(de)(de)截(jie)面(mian)(mian)。合格產(chan)品(pin)的(de)(de)銅芯或鋁(lv)(lv)芯表(biao)面(mian)(mian)應該具有金屬光澤，表(biao)面(mian)(mian)發(fa)黑的(de)(de)銅或表(biao)面(mian)(mian)發(fa)白的(de)(de)鋁(lv)(lv)說明已被氧化。

第三(san)、在購(gou)買電線(xian)時應注意查看(kan)質量(liang)合(he)格(ge)證書。如果(guo)電線(xian)的質量(liang)合(he)格(ge)，那么其電線(xian)質量(liang)應該也受過檢驗，不會有太(tai)大的問題。
