不合(he)格(ge)電線電纜的危害

電(dian)線電(dian)纜(lan)是用于傳輸電(dian)力、傳輸信(xin)息和實現電(dian)磁能(neng)量轉換的一大(da)類電(dian)工產品(pin)。在(zai)抽查過程(cheng)中(zhong)，發現了(le)大(da)量的不合格(ge)產品(pin)，這些劣(lie)質(zhi)產品(pin)給電(dian)力系統正常運行埋下諸多隱患。

1、標(biao)志(zhi)不(bu)合(he)格(ge)的電(dian)(dian)線電(dian)(dian)纜。標(biao)志(zhi)是電(dian)(dian)線電(dian)(dian)纜使用識(shi)別產(chan)(chan)品(pin)基本(ben)信息的主(zhu)要途徑(jing)，根據標(biao)準規定標(biao)志(zhi)的主(zhu)要內容(rong)是：產(chan)(chan)品(pin)型號、規格(ge)、標(biao)準號、廠名(ming)、產(chan)(chan)地等在一定的標(biao)示間距內，當標(biao)志(zhi)不(bu)合(he)格(ge)時，會造成施工人員識(shi)別錯誤，嚴重時會引發電(dian)(dian)氣事故。

2、結(jie)(jie)構尺寸(cun)不合格的電(dian)(dian)(dian)線(xian)(xian)電(dian)(dian)(dian)纜(lan)(lan)。結(jie)(jie)構尺寸(cun)的主要(yao)問題是護(hu)套厚度(du)，絕(jue)緣厚度(du)，當電(dian)(dian)(dian)纜(lan)(lan)的護(hu)套和絕(jue)緣厚度(du)不達標時，致(zhi)(zhi)使電(dian)(dian)(dian)線(xian)(xian)電(dian)(dian)(dian)纜(lan)(lan)耐電(dian)(dian)(dian)氣強度(du)會嚴重降低(di)，導(dao)致(zhi)(zhi)電(dian)(dian)(dian)線(xian)(xian)電(dian)(dian)(dian)纜(lan)(lan)的使用壽命(ming)縮短，嚴重時可(ke)導(dao)致(zhi)(zhi)電(dian)(dian)(dian)線(xian)(xian)電(dian)(dian)(dian)纜(lan)(lan)被擊穿，絕(jue)緣（護(hu)套）層起不到正常(chang)保護(hu)作用，從而(er)發生電(dian)(dian)(dian)氣短路和火災(zai)等現象。

3、護套(tao)式絕緣(yuan)(yuan)(yuan)老化前的(de)(de)(de)抗(kang)(kang)張強(qiang)度、伸長(chang)率合格的(de)(de)(de)電線(xian)電纜。絕緣(yuan)(yuan)(yuan)護套(tao)老化前的(de)(de)(de)抗(kang)(kang)張強(qiang)度、伸長(chang)率不合格直接大(da)大(da)縮短電線(xian)電纜的(de)(de)(de)工作用(yong)壽命，而(er)且在施工或在長(chang)時間(jian)通電且溫度較高(gao)的(de)(de)(de)環境中，極易出現絕緣(yuan)(yuan)(yuan)體斷裂，致(zhi)使帶電導(dao)體裸露，發生(sheng)能(neng)觸電式短路危險。其不合格的(de)(de)(de)主要原因(yin)是使用(yong)了(le)再生(sheng)料生(sheng)產，以降低產品成本，二(er)是不具備生(sheng)產資(zi)格小型企業。

4、導(dao)體(ti)(ti)(ti)電(dian)(dian)阻(zu)不合(he)格的(de)(de)(de)(de)(de)電(dian)(dian)線。導(dao)體(ti)(ti)(ti)電(dian)(dian)阻(zu)主(zhu)要(yao)(yao)(yao)(yao)是(shi)考(kao)核電(dian)(dian)線電(dian)(dian)纜的(de)(de)(de)(de)(de)導(dao)體(ti)(ti)(ti)材料以及(ji)截面是(shi)否符合(he)的(de)(de)(de)(de)(de)重要(yao)(yao)(yao)(yao)指(zhi)標。當導(dao)體(ti)(ti)(ti)電(dian)(dian)阻(zu)超(chao)標時(shi)，就增大(da)了(le)(le)電(dian)(dian)流在(zai)(zai)線路上通過(guo)(guo)時(shi)的(de)(de)(de)(de)(de)損耗(hao)，加劇了(le)(le)電(dian)(dian)線電(dian)(dian)纜的(de)(de)(de)(de)(de)發熱。導(dao)體(ti)(ti)(ti)電(dian)(dian)阻(zu)不合(he)格的(de)(de)(de)(de)(de)原因，主(zhu)要(yao)(yao)(yao)(yao)進企業為(wei)了(le)(le)降(jiang)低成(cheng)本，將占原材料成(cheng)本80%的(de)(de)(de)(de)(de)銅材縮水，要(yao)(yao)(yao)(yao)么降(jiang)低導(dao)體(ti)(ti)(ti)的(de)(de)(de)(de)(de)截面積，要(yao)(yao)(yao)(yao)么使(shi)(shi)用含雜質過(guo)(guo)高的(de)(de)(de)(de)(de)再生銅，這樣致使(shi)(shi)電(dian)(dian)線電(dian)(dian)纜的(de)(de)(de)(de)(de)導(dao)體(ti)(ti)(ti)電(dian)(dian)阻(zu)嚴重超(chao)標，在(zai)(zai)使(shi)(shi)用過(guo)(guo)程(cheng)中除易引發火(huo)災，還(huan)會加速包覆在(zai)(zai)電(dian)(dian)線外的(de)(de)(de)(de)(de)絕緣層(ceng)的(de)(de)(de)(de)(de)老(lao)化。

在購買電線電纜(lan)的過(guo)程中，消費(fei)者應注意以下幾個事

第一、要觀察電(dian)線(xian)的(de)外(wai)觀。合(he)格產(chan)品的(de)絕緣（護(hu)套(tao)）層柔(rou)軟、有(you)韌性和伸縮性、表面層緊密、光滑、無粗糙感。如果包裹電(dian)線(xian)的(de)塑料(liao)很容易(yi)被剝去，則存在塑料(liao)強度(du)不夠的(de)問題。

第二(er)、要看電線(xian)的截面(mian)。合格產(chan)品的銅芯(xin)或(huo)鋁(lv)芯(xin)表面(mian)應該具(ju)有(you)金屬(shu)光澤，表面(mian)發黑(hei)的銅或(huo)表面(mian)發白的鋁(lv)說明已被氧化。

第(di)三、在(zai)購買(mai)電(dian)線(xian)時應注意查(cha)看質量(liang)合(he)格(ge)證書(shu)。如果電(dian)線(xian)的(de)質量(liang)合(he)格(ge)，那(nei)么其電(dian)線(xian)質量(liang)應該(gai)也受過檢驗，不(bu)會有太(tai)大的(de)問題。
