不(bu)合格(ge)電線電纜(lan)的危害

電(dian)線電(dian)纜(lan)是(shi)用(yong)于傳輸電(dian)力、傳輸信息(xi)和實現電(dian)磁(ci)能量轉換的一(yi)大類電(dian)工產品(pin)。在(zai)抽查過(guo)程中(zhong)，發(fa)現了大量的不(bu)合格產品(pin)，這些(xie)劣質(zhi)產品(pin)給(gei)電(dian)力系(xi)統正(zheng)常運行埋下諸多隱患(huan)。

1、標(biao)(biao)志(zhi)不合格的電線電纜(lan)。標(biao)(biao)志(zhi)是(shi)電線電纜(lan)使(shi)用識別產品基本信(xin)息的主(zhu)要(yao)途徑，根據標(biao)(biao)準規(gui)(gui)定(ding)標(biao)(biao)志(zhi)的主(zhu)要(yao)內容是(shi)：產品型號、規(gui)(gui)格、標(biao)(biao)準號、廠(chang)名、產地等在一定(ding)的標(biao)(biao)示間距內，當(dang)標(biao)(biao)志(zhi)不合格時(shi)，會造成施工(gong)人員識別錯誤，嚴重時(shi)會引發(fa)電氣(qi)事故。

2、結構尺寸(cun)不合格的(de)電(dian)(dian)(dian)(dian)線電(dian)(dian)(dian)(dian)纜(lan)(lan)。結構尺寸(cun)的(de)主(zhu)要問題是護(hu)(hu)套(tao)(tao)厚度，絕(jue)緣(yuan)厚度，當電(dian)(dian)(dian)(dian)纜(lan)(lan)的(de)護(hu)(hu)套(tao)(tao)和(he)絕(jue)緣(yuan)厚度不達標時(shi)，致(zhi)使電(dian)(dian)(dian)(dian)線電(dian)(dian)(dian)(dian)纜(lan)(lan)耐電(dian)(dian)(dian)(dian)氣強度會嚴重降低(di)，導致(zhi)電(dian)(dian)(dian)(dian)線電(dian)(dian)(dian)(dian)纜(lan)(lan)的(de)使用壽命縮短，嚴重時(shi)可導致(zhi)電(dian)(dian)(dian)(dian)線電(dian)(dian)(dian)(dian)纜(lan)(lan)被擊穿(chuan)，絕(jue)緣(yuan)（護(hu)(hu)套(tao)(tao)）層起(qi)不到正常保護(hu)(hu)作用，從而發生(sheng)電(dian)(dian)(dian)(dian)氣短路和(he)火(huo)災等現象。

3、護套式絕(jue)緣(yuan)老(lao)化(hua)前的(de)抗(kang)張強(qiang)度(du)、伸長(chang)率合(he)格(ge)(ge)的(de)電(dian)線(xian)電(dian)纜。絕(jue)緣(yuan)護套老(lao)化(hua)前的(de)抗(kang)張強(qiang)度(du)、伸長(chang)率不(bu)合(he)格(ge)(ge)直(zhi)接大大縮短電(dian)線(xian)電(dian)纜的(de)工(gong)作用壽命，而且在施工(gong)或在長(chang)時間通電(dian)且溫(wen)度(du)較(jiao)高的(de)環境中，極(ji)易出現絕(jue)緣(yuan)體斷(duan)裂，致使帶電(dian)導體裸露，發生能觸電(dian)式短路危(wei)險。其不(bu)合(he)格(ge)(ge)的(de)主要原因是使用了再生料生產(chan)(chan)(chan)，以(yi)降(jiang)低產(chan)(chan)(chan)品成(cheng)本(ben)，二是不(bu)具備生產(chan)(chan)(chan)資格(ge)(ge)小型企業。

4、導體(ti)(ti)電(dian)(dian)(dian)阻(zu)不合(he)格的(de)(de)(de)(de)電(dian)(dian)(dian)線(xian)(xian)。導體(ti)(ti)電(dian)(dian)(dian)阻(zu)主要(yao)是考核電(dian)(dian)(dian)線(xian)(xian)電(dian)(dian)(dian)纜的(de)(de)(de)(de)導體(ti)(ti)材(cai)(cai)料以(yi)及截面是否符合(he)的(de)(de)(de)(de)重要(yao)指標。當導體(ti)(ti)電(dian)(dian)(dian)阻(zu)超標時，就增大了(le)電(dian)(dian)(dian)流在線(xian)(xian)路(lu)上通(tong)過(guo)時的(de)(de)(de)(de)損耗，加(jia)劇(ju)了(le)電(dian)(dian)(dian)線(xian)(xian)電(dian)(dian)(dian)纜的(de)(de)(de)(de)發(fa)熱。導體(ti)(ti)電(dian)(dian)(dian)阻(zu)不合(he)格的(de)(de)(de)(de)原因，主要(yao)進(jin)企業為(wei)了(le)降低(di)成本(ben)，將占原材(cai)(cai)料成本(ben)80%的(de)(de)(de)(de)銅材(cai)(cai)縮水，要(yao)么降低(di)導體(ti)(ti)的(de)(de)(de)(de)截面積，要(yao)么使用含雜質過(guo)高的(de)(de)(de)(de)再生銅，這樣致使電(dian)(dian)(dian)線(xian)(xian)電(dian)(dian)(dian)纜的(de)(de)(de)(de)導體(ti)(ti)電(dian)(dian)(dian)阻(zu)嚴重超標，在使用過(guo)程中除易引(yin)發(fa)火災，還會加(jia)速包(bao)覆在電(dian)(dian)(dian)線(xian)(xian)外(wai)的(de)(de)(de)(de)絕緣層(ceng)的(de)(de)(de)(de)老化。

在購買電線電纜的(de)過程中，消(xiao)費者應注意以下幾個事(shi)

第一(yi)、要觀察電線的外觀。合格(ge)產(chan)品的絕緣(yuan)（護套）層柔軟(ruan)、有韌性和伸縮性、表面層緊密、光滑、無(wu)粗糙感(gan)。如果包裹(guo)電線的塑料很容易被(bei)剝(bo)去，則存在塑料強度不(bu)夠的問(wen)題(ti)。

第二(er)、要(yao)看電線的(de)(de)截面(mian)。合格產品的(de)(de)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(fa)黑的(de)(de)銅或表(biao)面(mian)發(fa)白(bai)的(de)(de)鋁說明已被氧化(hua)。

第三、在(zai)購買(mai)電(dian)線時應注意查看質(zhi)量(liang)合格(ge)證書(shu)。如(ru)果電(dian)線的(de)質(zhi)量(liang)合格(ge)，那么其電(dian)線質(zhi)量(liang)應該也(ye)受過檢驗，不會有太大(da)的(de)問題。
