不合格電(dian)(dian)線電(dian)(dian)纜(lan)的危害

電(dian)線電(dian)纜是(shi)用于傳輸(shu)電(dian)力、傳輸(shu)信息和實現(xian)電(dian)磁能(neng)量轉換的(de)一大(da)類電(dian)工產(chan)(chan)品(pin)(pin)。在抽查過程中，發現(xian)了(le)大(da)量的(de)不合格產(chan)(chan)品(pin)(pin)，這(zhe)些劣質(zhi)產(chan)(chan)品(pin)(pin)給電(dian)力系統正常運行埋(mai)下(xia)諸多(duo)隱患。

1、標(biao)(biao)志(zhi)不合格的(de)電(dian)(dian)線電(dian)(dian)纜(lan)。標(biao)(biao)志(zhi)是(shi)(shi)電(dian)(dian)線電(dian)(dian)纜(lan)使用識別產(chan)品(pin)基(ji)本(ben)信息(xi)的(de)主要途(tu)徑(jing)，根據標(biao)(biao)準規定(ding)標(biao)(biao)志(zhi)的(de)主要內容是(shi)(shi)：產(chan)品(pin)型(xing)號(hao)、規格、標(biao)(biao)準號(hao)、廠名、產(chan)地等在一定(ding)的(de)標(biao)(biao)示間(jian)距(ju)內，當標(biao)(biao)志(zhi)不合格時，會造成施工人員識別錯誤(wu)，嚴(yan)重時會引發電(dian)(dian)氣事故(gu)。

2、結(jie)構(gou)尺寸不合格的(de)(de)電(dian)(dian)(dian)(dian)線電(dian)(dian)(dian)(dian)纜(lan)。結(jie)構(gou)尺寸的(de)(de)主要問(wen)題(ti)是護(hu)套(tao)厚度(du)，絕(jue)緣(yuan)厚度(du)，當電(dian)(dian)(dian)(dian)纜(lan)的(de)(de)護(hu)套(tao)和絕(jue)緣(yuan)厚度(du)不達標(biao)時(shi)，致(zhi)使(shi)電(dian)(dian)(dian)(dian)線電(dian)(dian)(dian)(dian)纜(lan)耐電(dian)(dian)(dian)(dian)氣強(qiang)度(du)會嚴重(zhong)(zhong)降(jiang)低(di)，導(dao)致(zhi)電(dian)(dian)(dian)(dian)線電(dian)(dian)(dian)(dian)纜(lan)的(de)(de)使(shi)用壽命縮(suo)短(duan)，嚴重(zhong)(zhong)時(shi)可(ke)導(dao)致(zhi)電(dian)(dian)(dian)(dian)線電(dian)(dian)(dian)(dian)纜(lan)被擊(ji)穿，絕(jue)緣(yuan)（護(hu)套(tao)）層起(qi)不到正常保護(hu)作用，從而發(fa)生(sheng)電(dian)(dian)(dian)(dian)氣短(duan)路和火(huo)災(zai)等現象。

3、護(hu)套(tao)式(shi)絕(jue)緣(yuan)老化前(qian)的(de)抗張(zhang)強(qiang)度(du)(du)(du)、伸(shen)(shen)長(chang)(chang)率合格的(de)電(dian)(dian)線(xian)電(dian)(dian)纜。絕(jue)緣(yuan)護(hu)套(tao)老化前(qian)的(de)抗張(zhang)強(qiang)度(du)(du)(du)、伸(shen)(shen)長(chang)(chang)率不合格直接(jie)大(da)大(da)縮短電(dian)(dian)線(xian)電(dian)(dian)纜的(de)工作(zuo)用(yong)壽(shou)命，而且在施工或(huo)在長(chang)(chang)時間通電(dian)(dian)且溫度(du)(du)(du)較高的(de)環境中，極(ji)易出現絕(jue)緣(yuan)體斷裂，致(zhi)使帶電(dian)(dian)導體裸(luo)露，發(fa)生(sheng)(sheng)能觸電(dian)(dian)式(shi)短路危險。其不合格的(de)主要原因是使用(yong)了再生(sheng)(sheng)料生(sheng)(sheng)產(chan)，以降(jiang)低產(chan)品成本，二是不具備生(sheng)(sheng)產(chan)資(zi)格小型企(qi)業。

4、導(dao)(dao)體(ti)電(dian)(dian)(dian)(dian)(dian)(dian)阻(zu)不合(he)格(ge)的(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)線(xian)。導(dao)(dao)體(ti)電(dian)(dian)(dian)(dian)(dian)(dian)阻(zu)主(zhu)要是(shi)考核電(dian)(dian)(dian)(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)(dian)(dian)(dian)纜的(de)(de)導(dao)(dao)體(ti)材料以(yi)及截面是(shi)否(fou)符合(he)的(de)(de)重要指標。當導(dao)(dao)體(ti)電(dian)(dian)(dian)(dian)(dian)(dian)阻(zu)超標時(shi)，就(jiu)增大了電(dian)(dian)(dian)(dian)(dian)(dian)流在(zai)線(xian)路(lu)上通過(guo)時(shi)的(de)(de)損耗，加劇了電(dian)(dian)(dian)(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)(dian)(dian)(dian)纜的(de)(de)發熱。導(dao)(dao)體(ti)電(dian)(dian)(dian)(dian)(dian)(dian)阻(zu)不合(he)格(ge)的(de)(de)原因(yin)，主(zhu)要進企業為(wei)了降低成(cheng)本，將(jiang)占原材料成(cheng)本80%的(de)(de)銅材縮水，要么(me)降低導(dao)(dao)體(ti)的(de)(de)截面積，要么(me)使(shi)用含雜(za)質過(guo)高的(de)(de)再生(sheng)銅，這樣致使(shi)電(dian)(dian)(dian)(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)(dian)(dian)(dian)纜的(de)(de)導(dao)(dao)體(ti)電(dian)(dian)(dian)(dian)(dian)(dian)阻(zu)嚴重超標，在(zai)使(shi)用過(guo)程中除易引發火(huo)災，還(huan)會加速包覆(fu)在(zai)電(dian)(dian)(dian)(dian)(dian)(dian)線(xian)外的(de)(de)絕緣層的(de)(de)老化。

在(zai)購買(mai)電(dian)線(xian)電(dian)纜的過程(cheng)中，消費(fei)者應注意以下幾個事

第一(yi)、要觀察電(dian)(dian)線(xian)的外觀。合(he)格產品的絕緣（護套）層(ceng)柔軟、有韌性和伸縮(suo)性、表(biao)面層(ceng)緊密、光滑、無(wu)粗糙(cao)感。如果包裹電(dian)(dian)線(xian)的塑料很容易被剝去，則存在塑料強度不(bu)夠的問(wen)題。

第二、要看電(dian)線的截(jie)面。合格產(chan)品的銅芯(xin)或(huo)鋁芯(xin)表面應該(gai)具有金屬光澤(ze)，表面發黑的銅或(huo)表面發白(bai)的鋁說明(ming)已被氧化(hua)。

第三(san)、在購(gou)買電(dian)線(xian)(xian)時應注(zhu)意查看質量合格證書。如果(guo)電(dian)線(xian)(xian)的質量合格，那么其電(dian)線(xian)(xian)質量應該也受過檢驗，不會(hui)有太(tai)大的問題。
