不合格電(dian)線電(dian)纜的危害

電(dian)線電(dian)纜是用于傳(chuan)輸電(dian)力、傳(chuan)輸信息(xi)和(he)實現(xian)電(dian)磁能量轉換的(de)一大(da)(da)類電(dian)工產品。在抽查過程中(zhong)，發現(xian)了大(da)(da)量的(de)不(bu)合格(ge)產品，這些劣(lie)質產品給電(dian)力系統正常運行埋下諸多隱患。

1、標(biao)志(zhi)不(bu)合(he)(he)格的(de)電(dian)線電(dian)纜。標(biao)志(zhi)是(shi)電(dian)線電(dian)纜使(shi)用識(shi)別產品(pin)基(ji)本信息的(de)主要(yao)途徑，根據(ju)標(biao)準規定標(biao)志(zhi)的(de)主要(yao)內(nei)容是(shi)：產品(pin)型號(hao)、規格、標(biao)準號(hao)、廠名、產地等在一定的(de)標(biao)示間(jian)距(ju)內(nei)，當標(biao)志(zhi)不(bu)合(he)(he)格時(shi)(shi)，會(hui)造(zao)成施(shi)工人(ren)員(yuan)識(shi)別錯(cuo)誤，嚴重(zhong)時(shi)(shi)會(hui)引發電(dian)氣事故。

2、結構(gou)尺(chi)寸不合格的(de)電(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)纜(lan)。結構(gou)尺(chi)寸的(de)主要問題是護(hu)套(tao)厚(hou)度(du)，絕(jue)緣厚(hou)度(du)，當電(dian)(dian)(dian)纜(lan)的(de)護(hu)套(tao)和絕(jue)緣厚(hou)度(du)不達標時，致(zhi)(zhi)使電(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)纜(lan)耐電(dian)(dian)(dian)氣強度(du)會(hui)嚴(yan)重降(jiang)低，導致(zhi)(zhi)電(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)纜(lan)的(de)使用壽命縮(suo)短，嚴(yan)重時可導致(zhi)(zhi)電(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)纜(lan)被擊穿，絕(jue)緣（護(hu)套(tao)）層(ceng)起不到正常保護(hu)作用，從而發生電(dian)(dian)(dian)氣短路和火災等現象。

3、護套(tao)式絕緣(yuan)老化前(qian)的(de)抗(kang)張強度(du)、伸長率(lv)合(he)格的(de)電(dian)線電(dian)纜。絕緣(yuan)護套(tao)老化前(qian)的(de)抗(kang)張強度(du)、伸長率(lv)不(bu)合(he)格直接(jie)大大縮短電(dian)線電(dian)纜的(de)工作用壽命，而且(qie)在(zai)施工或在(zai)長時間通電(dian)且(qie)溫度(du)較高的(de)環境(jing)中，極(ji)易出現(xian)絕緣(yuan)體斷裂，致(zhi)使帶電(dian)導體裸露，發(fa)生(sheng)能觸電(dian)式短路危險。其(qi)不(bu)合(he)格的(de)主(zhu)要原因是使用了再生(sheng)料生(sheng)產(chan)(chan)，以(yi)降低產(chan)(chan)品成本，二(er)是不(bu)具備(bei)生(sheng)產(chan)(chan)資格小型企業。

4、導體(ti)電(dian)(dian)(dian)(dian)(dian)阻(zu)不(bu)合(he)(he)格的(de)(de)電(dian)(dian)(dian)(dian)(dian)線(xian)(xian)。導體(ti)電(dian)(dian)(dian)(dian)(dian)阻(zu)主(zhu)要(yao)是(shi)(shi)考核電(dian)(dian)(dian)(dian)(dian)線(xian)(xian)電(dian)(dian)(dian)(dian)(dian)纜的(de)(de)導體(ti)材(cai)料以及截面(mian)是(shi)(shi)否符合(he)(he)的(de)(de)重(zhong)要(yao)指標(biao)。當導體(ti)電(dian)(dian)(dian)(dian)(dian)阻(zu)超標(biao)時，就(jiu)增大了(le)電(dian)(dian)(dian)(dian)(dian)流在線(xian)(xian)路(lu)上通過時的(de)(de)損(sun)耗(hao)，加劇了(le)電(dian)(dian)(dian)(dian)(dian)線(xian)(xian)電(dian)(dian)(dian)(dian)(dian)纜的(de)(de)發(fa)熱。導體(ti)電(dian)(dian)(dian)(dian)(dian)阻(zu)不(bu)合(he)(he)格的(de)(de)原(yuan)(yuan)因，主(zhu)要(yao)進企(qi)業為了(le)降低成本(ben)(ben)，將占原(yuan)(yuan)材(cai)料成本(ben)(ben)80%的(de)(de)銅材(cai)縮水，要(yao)么降低導體(ti)的(de)(de)截面(mian)積，要(yao)么使(shi)用含雜質(zhi)過高的(de)(de)再生(sheng)銅，這(zhe)樣致使(shi)電(dian)(dian)(dian)(dian)(dian)線(xian)(xian)電(dian)(dian)(dian)(dian)(dian)纜的(de)(de)導體(ti)電(dian)(dian)(dian)(dian)(dian)阻(zu)嚴重(zhong)超標(biao)，在使(shi)用過程中(zhong)除(chu)易(yi)引(yin)發(fa)火(huo)災，還會(hui)加速(su)包覆在電(dian)(dian)(dian)(dian)(dian)線(xian)(xian)外的(de)(de)絕(jue)緣層的(de)(de)老(lao)化。

在(zai)購買電線(xian)電纜的過程中，消(xiao)費者應注意以(yi)下幾(ji)個事

第(di)一、要觀察電線(xian)的(de)外觀。合(he)格產品的(de)絕緣（護套）層柔軟、有韌性和伸縮性、表面層緊密、光滑、無粗糙感。如(ru)果包裹電線(xian)的(de)塑料(liao)很容易(yi)被(bei)剝去，則存在塑料(liao)強度不夠的(de)問題(ti)。

第二、要看電(dian)線的截面(mian)(mian)(mian)。合格產(chan)品的銅芯或鋁芯表(biao)面(mian)(mian)(mian)應(ying)該具(ju)有金屬光澤，表(biao)面(mian)(mian)(mian)發黑(hei)的銅或表(biao)面(mian)(mian)(mian)發白(bai)的鋁說(shuo)明已(yi)被氧化(hua)。

第三、在購買電(dian)線(xian)時應(ying)注意查(cha)看質(zhi)(zhi)量合(he)(he)格(ge)證書(shu)。如果電(dian)線(xian)的(de)質(zhi)(zhi)量合(he)(he)格(ge)，那么其(qi)電(dian)線(xian)質(zhi)(zhi)量應(ying)該也受過檢驗(yan)，不會有太大的(de)問題。
