不合格電線(xian)電纜的危害

電(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)纜是用(yong)于傳輸電(dian)(dian)(dian)力、傳輸信(xin)息和實現(xian)電(dian)(dian)(dian)磁能量轉換的(de)一大類電(dian)(dian)(dian)工產(chan)品。在抽查(cha)過程(cheng)中，發現(xian)了大量的(de)不(bu)合(he)格產(chan)品，這(zhe)些劣質產(chan)品給(gei)電(dian)(dian)(dian)力系統正常運行埋下諸多(duo)隱患。

1、標(biao)(biao)志(zhi)(zhi)不合(he)格(ge)的(de)(de)電(dian)(dian)線(xian)電(dian)(dian)纜。標(biao)(biao)志(zhi)(zhi)是電(dian)(dian)線(xian)電(dian)(dian)纜使用識(shi)別產(chan)品(pin)基本(ben)信息的(de)(de)主(zhu)要途(tu)徑，根(gen)據(ju)標(biao)(biao)準(zhun)規定標(biao)(biao)志(zhi)(zhi)的(de)(de)主(zhu)要內容是：產(chan)品(pin)型(xing)號、規格(ge)、標(biao)(biao)準(zhun)號、廠名、產(chan)地等在(zai)一定的(de)(de)標(biao)(biao)示(shi)間距內，當標(biao)(biao)志(zhi)(zhi)不合(he)格(ge)時，會(hui)造成施工(gong)人員(yuan)識(shi)別錯誤，嚴重時會(hui)引發電(dian)(dian)氣(qi)事故。

2、結(jie)構(gou)尺(chi)寸(cun)不合格的(de)電(dian)線(xian)(xian)電(dian)纜(lan)。結(jie)構(gou)尺(chi)寸(cun)的(de)主(zhu)要(yao)問題是(shi)護(hu)套厚度，絕緣厚度，當電(dian)纜(lan)的(de)護(hu)套和絕緣厚度不達(da)標時(shi)，致使電(dian)線(xian)(xian)電(dian)纜(lan)耐電(dian)氣強(qiang)度會嚴重降低，導(dao)致電(dian)線(xian)(xian)電(dian)纜(lan)的(de)使用(yong)壽命縮短(duan)(duan)，嚴重時(shi)可(ke)導(dao)致電(dian)線(xian)(xian)電(dian)纜(lan)被擊穿，絕緣（護(hu)套）層起不到(dao)正常保護(hu)作用(yong)，從而發生電(dian)氣短(duan)(duan)路(lu)和火災等(deng)現象。

3、護(hu)套式絕緣(yuan)老化前(qian)的(de)(de)抗張(zhang)強度、伸長(chang)率合(he)格的(de)(de)電(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)纜。絕緣(yuan)護(hu)套老化前(qian)的(de)(de)抗張(zhang)強度、伸長(chang)率不合(he)格直接大(da)(da)大(da)(da)縮短(duan)電(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)纜的(de)(de)工作用壽命，而且在施工或在長(chang)時間通(tong)電(dian)(dian)(dian)且溫度較高(gao)的(de)(de)環境中(zhong)，極易出現絕緣(yuan)體(ti)斷裂(lie)，致使帶電(dian)(dian)(dian)導體(ti)裸(luo)露，發生能觸電(dian)(dian)(dian)式短(duan)路(lu)危險。其不合(he)格的(de)(de)主(zhu)要原(yuan)因是(shi)使用了再生料生產(chan)，以(yi)降低(di)產(chan)品成本，二是(shi)不具備生產(chan)資格小型企業。

4、導(dao)體(ti)電(dian)(dian)(dian)阻(zu)不合格的(de)(de)(de)(de)電(dian)(dian)(dian)線(xian)(xian)。導(dao)體(ti)電(dian)(dian)(dian)阻(zu)主(zhu)要(yao)(yao)是考核電(dian)(dian)(dian)線(xian)(xian)電(dian)(dian)(dian)纜的(de)(de)(de)(de)導(dao)體(ti)材料以及(ji)截面是否符合的(de)(de)(de)(de)重要(yao)(yao)指標(biao)。當導(dao)體(ti)電(dian)(dian)(dian)阻(zu)超標(biao)時，就增(zeng)大(da)了(le)電(dian)(dian)(dian)流在線(xian)(xian)路(lu)上通(tong)過時的(de)(de)(de)(de)損耗，加(jia)劇了(le)電(dian)(dian)(dian)線(xian)(xian)電(dian)(dian)(dian)纜的(de)(de)(de)(de)發熱。導(dao)體(ti)電(dian)(dian)(dian)阻(zu)不合格的(de)(de)(de)(de)原(yuan)因，主(zhu)要(yao)(yao)進企業為了(le)降低成本，將占原(yuan)材料成本80%的(de)(de)(de)(de)銅材縮水，要(yao)(yao)么(me)降低導(dao)體(ti)的(de)(de)(de)(de)截面積，要(yao)(yao)么(me)使(shi)(shi)(shi)用(yong)含雜(za)質過高的(de)(de)(de)(de)再生銅，這(zhe)樣致使(shi)(shi)(shi)電(dian)(dian)(dian)線(xian)(xian)電(dian)(dian)(dian)纜的(de)(de)(de)(de)導(dao)體(ti)電(dian)(dian)(dian)阻(zu)嚴(yan)重超標(biao)，在使(shi)(shi)(shi)用(yong)過程中(zhong)除易引發火災，還會加(jia)速包(bao)覆在電(dian)(dian)(dian)線(xian)(xian)外的(de)(de)(de)(de)絕緣(yuan)層的(de)(de)(de)(de)老化。

在購買電線電纜的過程中，消費者應(ying)注意以下幾個事

第(di)一(yi)、要觀察電線的(de)外觀。合格產品(pin)的(de)絕緣（護套(tao)）層柔軟、有韌性(xing)和(he)伸縮性(xing)、表面層緊密、光滑、無(wu)粗糙(cao)感。如果包裹電線的(de)塑(su)料很容易被(bei)剝去，則存在(zai)塑(su)料強(qiang)度不夠的(de)問題。

第二、要看電線的(de)截(jie)面(mian)(mian)。合格(ge)產(chan)品的(de)銅芯(xin)或(huo)鋁芯(xin)表(biao)(biao)面(mian)(mian)應該具有金屬(shu)光澤，表(biao)(biao)面(mian)(mian)發黑的(de)銅或(huo)表(biao)(biao)面(mian)(mian)發白的(de)鋁說(shuo)明已(yi)被氧(yang)化。

第(di)三、在購(gou)買電(dian)(dian)線(xian)時應注意查看質(zhi)量合格證書。如果電(dian)(dian)線(xian)的質(zhi)量合格，那(nei)么其電(dian)(dian)線(xian)質(zhi)量應該也受過檢驗，不(bu)會有太(tai)大的問題。
