不合格(ge)電線電纜的危害

電(dian)線電(dian)纜是(shi)用(yong)于傳輸電(dian)力、傳輸信息和(he)實(shi)現電(dian)磁能量(liang)(liang)轉換的一大類電(dian)工(gong)產品(pin)。在(zai)抽查過(guo)程中，發現了大量(liang)(liang)的不合格產品(pin)，這(zhe)些(xie)劣質產品(pin)給電(dian)力系統正常運行埋下(xia)諸多(duo)隱患(huan)。

1、標(biao)志(zhi)(zhi)不合格的(de)(de)電(dian)(dian)線(xian)電(dian)(dian)纜(lan)。標(biao)志(zhi)(zhi)是電(dian)(dian)線(xian)電(dian)(dian)纜(lan)使用識別產(chan)品(pin)(pin)基本信息的(de)(de)主要途徑，根據(ju)標(biao)準規定標(biao)志(zhi)(zhi)的(de)(de)主要內容(rong)是：產(chan)品(pin)(pin)型號(hao)、規格、標(biao)準號(hao)、廠名、產(chan)地(di)等在一定的(de)(de)標(biao)示間距(ju)內，當標(biao)志(zhi)(zhi)不合格時(shi)，會造(zao)成施工人員識別錯誤，嚴(yan)重時(shi)會引(yin)發電(dian)(dian)氣事故(gu)。

2、結構(gou)尺(chi)寸(cun)不合格的(de)電(dian)線(xian)電(dian)纜(lan)(lan)。結構(gou)尺(chi)寸(cun)的(de)主要問(wen)題(ti)是護套(tao)厚度，絕(jue)緣(yuan)厚度，當電(dian)纜(lan)(lan)的(de)護套(tao)和(he)絕(jue)緣(yuan)厚度不達(da)標時，致使(shi)電(dian)線(xian)電(dian)纜(lan)(lan)耐電(dian)氣強(qiang)度會嚴重降(jiang)低，導致電(dian)線(xian)電(dian)纜(lan)(lan)的(de)使(shi)用(yong)壽命縮短(duan)，嚴重時可導致電(dian)線(xian)電(dian)纜(lan)(lan)被擊穿，絕(jue)緣(yuan)（護套(tao)）層起不到正(zheng)常保護作(zuo)用(yong)，從而發生電(dian)氣短(duan)路和(he)火災等(deng)現象。

3、護套(tao)式(shi)絕(jue)緣(yuan)老(lao)化(hua)前的(de)(de)抗(kang)張強度、伸(shen)長(chang)(chang)率合(he)格(ge)(ge)的(de)(de)電(dian)線電(dian)纜。絕(jue)緣(yuan)護套(tao)老(lao)化(hua)前的(de)(de)抗(kang)張強度、伸(shen)長(chang)(chang)率不(bu)合(he)格(ge)(ge)直接大大縮短(duan)電(dian)線電(dian)纜的(de)(de)工作用壽命，而(er)且(qie)在施工或在長(chang)(chang)時間通電(dian)且(qie)溫度較高的(de)(de)環境中，極易(yi)出現絕(jue)緣(yuan)體斷裂，致使帶(dai)電(dian)導體裸露，發生(sheng)(sheng)能觸(chu)電(dian)式(shi)短(duan)路危險。其(qi)不(bu)合(he)格(ge)(ge)的(de)(de)主要原(yuan)因是(shi)使用了再生(sheng)(sheng)料生(sheng)(sheng)產，以降低產品成本，二是(shi)不(bu)具備生(sheng)(sheng)產資(zi)格(ge)(ge)小型(xing)企業(ye)。

4、導(dao)(dao)體電(dian)(dian)(dian)阻(zu)(zu)不合格(ge)的(de)(de)(de)(de)電(dian)(dian)(dian)線(xian)。導(dao)(dao)體電(dian)(dian)(dian)阻(zu)(zu)主要(yao)(yao)是(shi)考核(he)電(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)纜的(de)(de)(de)(de)導(dao)(dao)體材料以及截面是(shi)否符(fu)合的(de)(de)(de)(de)重(zhong)要(yao)(yao)指標。當導(dao)(dao)體電(dian)(dian)(dian)阻(zu)(zu)超標時，就增大了電(dian)(dian)(dian)流在線(xian)路上通(tong)過時的(de)(de)(de)(de)損耗(hao)，加劇(ju)了電(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)纜的(de)(de)(de)(de)發熱。導(dao)(dao)體電(dian)(dian)(dian)阻(zu)(zu)不合格(ge)的(de)(de)(de)(de)原(yuan)(yuan)因，主要(yao)(yao)進企業為(wei)了降低成本(ben)，將占原(yuan)(yuan)材料成本(ben)80%的(de)(de)(de)(de)銅材縮水，要(yao)(yao)么降低導(dao)(dao)體的(de)(de)(de)(de)截面積，要(yao)(yao)么使(shi)用含(han)雜(za)質過高的(de)(de)(de)(de)再生銅，這樣致使(shi)電(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)纜的(de)(de)(de)(de)導(dao)(dao)體電(dian)(dian)(dian)阻(zu)(zu)嚴重(zhong)超標，在使(shi)用過程中除(chu)易(yi)引發火災，還會加速包覆在電(dian)(dian)(dian)線(xian)外的(de)(de)(de)(de)絕緣層(ceng)的(de)(de)(de)(de)老(lao)化。

在購買電線電纜的過程中，消(xiao)費(fei)者應(ying)注(zhu)意以(yi)下幾個事(shi)

第(di)一(yi)、要觀察電(dian)線(xian)的外觀。合格產品的絕緣（護套）層柔軟、有韌性和伸縮性、表面層緊密、光滑、無粗糙(cao)感。如果包裹(guo)電(dian)線(xian)的塑料(liao)很容易被剝去，則存在塑料(liao)強度不夠的問題(ti)。

第二、要看電線(xian)的截面(mian)(mian)。合格產品的銅芯或鋁芯表面(mian)(mian)應該具有金屬光澤，表面(mian)(mian)發黑的銅或表面(mian)(mian)發白的鋁說明已被(bei)氧化。

第三(san)、在購買(mai)電(dian)線(xian)時應注意查(cha)看質量合格證書(shu)。如果電(dian)線(xian)的質量合格，那(nei)么其電(dian)線(xian)質量應該也受過檢驗，不(bu)會(hui)有太大的問題。
