不合格電(dian)線電(dian)纜的危害

電(dian)線電(dian)纜是用于(yu)傳(chuan)輸(shu)電(dian)力、傳(chuan)輸(shu)信息(xi)和實現(xian)電(dian)磁能(neng)量轉換的一大類電(dian)工產(chan)品(pin)。在抽查(cha)過程中，發現(xian)了大量的不合格產(chan)品(pin)，這些劣質產(chan)品(pin)給電(dian)力系統正(zheng)常運行埋下諸(zhu)多(duo)隱(yin)患。

1、標(biao)志不合格的(de)電(dian)線(xian)電(dian)纜(lan)。標(biao)志是電(dian)線(xian)電(dian)纜(lan)使用識別(bie)產(chan)品(pin)基(ji)本信(xin)息的(de)主要途(tu)徑，根據標(biao)準(zhun)規(gui)定(ding)標(biao)志的(de)主要內(nei)容是：產(chan)品(pin)型號、規(gui)格、標(biao)準(zhun)號、廠(chang)名、產(chan)地等在一(yi)定(ding)的(de)標(biao)示(shi)間距內(nei)，當標(biao)志不合格時(shi)，會造成施工(gong)人員(yuan)識別(bie)錯誤，嚴重時(shi)會引發電(dian)氣(qi)事故。

2、結構(gou)尺寸不合格的(de)電(dian)線(xian)電(dian)纜(lan)。結構(gou)尺寸的(de)主(zhu)要(yao)問題是護(hu)套厚(hou)(hou)度(du)，絕緣厚(hou)(hou)度(du)，當電(dian)纜(lan)的(de)護(hu)套和(he)絕緣厚(hou)(hou)度(du)不達(da)標時，致使(shi)電(dian)線(xian)電(dian)纜(lan)耐電(dian)氣(qi)強度(du)會(hui)嚴重(zhong)(zhong)降低，導致電(dian)線(xian)電(dian)纜(lan)的(de)使(shi)用壽命(ming)縮短(duan)，嚴重(zhong)(zhong)時可(ke)導致電(dian)線(xian)電(dian)纜(lan)被(bei)擊(ji)穿(chuan)，絕緣（護(hu)套）層起不到正常保護(hu)作(zuo)用，從而(er)發生電(dian)氣(qi)短(duan)路和(he)火災等現象。

3、護套式(shi)絕緣老化前的抗張強度、伸長率合格的電(dian)(dian)(dian)線電(dian)(dian)(dian)纜。絕緣護套老化前的抗張強度、伸長率不(bu)合格直(zhi)接大大縮(suo)短(duan)電(dian)(dian)(dian)線電(dian)(dian)(dian)纜的工作用壽命，而且在(zai)(zai)施工或在(zai)(zai)長時間通電(dian)(dian)(dian)且溫(wen)度較(jiao)高的環(huan)境(jing)中，極易出現絕緣體(ti)斷裂，致(zhi)使帶電(dian)(dian)(dian)導體(ti)裸(luo)露，發生(sheng)(sheng)能觸電(dian)(dian)(dian)式(shi)短(duan)路危險(xian)。其(qi)不(bu)合格的主(zhu)要原因(yin)是使用了再生(sheng)(sheng)料(liao)生(sheng)(sheng)產，以降低產品成本，二是不(bu)具備生(sheng)(sheng)產資格小型企業。

4、導(dao)體(ti)(ti)電(dian)(dian)阻不(bu)合(he)(he)格的(de)(de)(de)電(dian)(dian)線(xian)(xian)。導(dao)體(ti)(ti)電(dian)(dian)阻主(zhu)要(yao)是(shi)考核電(dian)(dian)線(xian)(xian)電(dian)(dian)纜(lan)的(de)(de)(de)導(dao)體(ti)(ti)材料(liao)以及截(jie)(jie)面是(shi)否符合(he)(he)的(de)(de)(de)重(zhong)要(yao)指標(biao)。當導(dao)體(ti)(ti)電(dian)(dian)阻超標(biao)時，就增大了(le)(le)電(dian)(dian)流在(zai)線(xian)(xian)路上(shang)通過時的(de)(de)(de)損耗，加劇了(le)(le)電(dian)(dian)線(xian)(xian)電(dian)(dian)纜(lan)的(de)(de)(de)發熱(re)。導(dao)體(ti)(ti)電(dian)(dian)阻不(bu)合(he)(he)格的(de)(de)(de)原(yuan)因(yin)，主(zhu)要(yao)進企業為了(le)(le)降(jiang)低(di)成本(ben)，將占原(yuan)材料(liao)成本(ben)80%的(de)(de)(de)銅材縮水，要(yao)么降(jiang)低(di)導(dao)體(ti)(ti)的(de)(de)(de)截(jie)(jie)面積，要(yao)么使(shi)用含(han)雜質(zhi)過高的(de)(de)(de)再生銅，這樣致使(shi)電(dian)(dian)線(xian)(xian)電(dian)(dian)纜(lan)的(de)(de)(de)導(dao)體(ti)(ti)電(dian)(dian)阻嚴重(zhong)超標(biao)，在(zai)使(shi)用過程(cheng)中除易(yi)引(yin)發火(huo)災，還(huan)會加速包覆在(zai)電(dian)(dian)線(xian)(xian)外(wai)的(de)(de)(de)絕緣層的(de)(de)(de)老化(hua)。

在購買電(dian)線電(dian)纜的過(guo)程中(zhong)，消(xiao)費者應注意以下幾個事

第一(yi)、要觀(guan)察電線(xian)的(de)外觀(guan)。合格產品的(de)絕緣（護套）層柔軟、有韌性和伸(shen)縮性、表面層緊密、光滑、無粗糙感。如(ru)果包裹(guo)電線(xian)的(de)塑料很容易被剝去，則存在塑料強度不夠的(de)問題。

第二、要看電線的截面。合格產品的銅(tong)芯或(huo)鋁芯表面應該具有金(jin)屬(shu)光(guang)澤，表面發黑的銅(tong)或(huo)表面發白的鋁說明已被氧化。

第三、在購買電(dian)線(xian)時應(ying)注意查看質量合(he)格證書(shu)。如果電(dian)線(xian)的質量合(he)格，那么其電(dian)線(xian)質量應(ying)該也(ye)受過檢驗，不會有太大(da)的問題。
