不(bu)合格(ge)電線電纜的危害(hai)

電線電纜是用于(yu)傳(chuan)輸電力、傳(chuan)輸信息和(he)實現電磁能(neng)量轉換的一(yi)大類電工產品(pin)。在抽(chou)查過程(cheng)中，發現了大量的不(bu)合格產品(pin)，這些劣質(zhi)產品(pin)給電力系統正常運行埋下(xia)諸多(duo)隱患。

1、標(biao)(biao)(biao)志不(bu)合(he)格的(de)(de)電(dian)(dian)線(xian)電(dian)(dian)纜(lan)(lan)。標(biao)(biao)(biao)志是(shi)電(dian)(dian)線(xian)電(dian)(dian)纜(lan)(lan)使(shi)用識別(bie)(bie)產品(pin)基(ji)本信息(xi)的(de)(de)主要(yao)途徑，根據(ju)標(biao)(biao)(biao)準(zhun)規定標(biao)(biao)(biao)志的(de)(de)主要(yao)內(nei)容是(shi)：產品(pin)型號、規格、標(biao)(biao)(biao)準(zhun)號、廠名、產地等在(zai)一定的(de)(de)標(biao)(biao)(biao)示間距(ju)內(nei)，當標(biao)(biao)(biao)志不(bu)合(he)格時(shi)，會造成施工人(ren)員(yuan)識別(bie)(bie)錯誤，嚴重時(shi)會引發電(dian)(dian)氣(qi)事故。

2、結構尺寸(cun)不(bu)合格的電(dian)線電(dian)纜。結構尺寸(cun)的主要問題是(shi)護(hu)套厚度(du)，絕緣(yuan)厚度(du)，當電(dian)纜的護(hu)套和絕緣(yuan)厚度(du)不(bu)達(da)標(biao)時，致使電(dian)線電(dian)纜耐電(dian)氣強度(du)會嚴重降低，導(dao)(dao)致電(dian)線電(dian)纜的使用(yong)壽命縮短，嚴重時可(ke)導(dao)(dao)致電(dian)線電(dian)纜被擊(ji)穿，絕緣(yuan)（護(hu)套）層起(qi)不(bu)到正常保護(hu)作用(yong)，從而(er)發生電(dian)氣短路和火災(zai)等現象。

3、護(hu)套式絕緣(yuan)老化前的(de)(de)抗(kang)張強度、伸長率合格(ge)的(de)(de)電(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)纜。絕緣(yuan)護(hu)套老化前的(de)(de)抗(kang)張強度、伸長率不合格(ge)直接(jie)大大縮短(duan)電(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)纜的(de)(de)工作(zuo)用壽(shou)命(ming)，而且(qie)在(zai)施工或在(zai)長時間通電(dian)(dian)(dian)且(qie)溫度較(jiao)高的(de)(de)環(huan)境(jing)中，極易出現(xian)絕緣(yuan)體斷裂(lie)，致使帶(dai)電(dian)(dian)(dian)導體裸露，發(fa)生能觸電(dian)(dian)(dian)式短(duan)路危險。其不合格(ge)的(de)(de)主要原因(yin)是使用了(le)再生料(liao)生產，以(yi)降低產品成本，二是不具備生產資格(ge)小(xiao)型企業。

4、導體電(dian)(dian)阻(zu)不(bu)合格(ge)的(de)電(dian)(dian)線(xian)。導體電(dian)(dian)阻(zu)主要是(shi)考核(he)電(dian)(dian)線(xian)電(dian)(dian)纜(lan)的(de)導體材(cai)(cai)料(liao)以及截面是(shi)否(fou)符(fu)合的(de)重(zhong)要指(zhi)標。當導體電(dian)(dian)阻(zu)超標時，就增(zeng)大(da)了(le)電(dian)(dian)流(liu)在線(xian)路上通過時的(de)損耗，加(jia)劇了(le)電(dian)(dian)線(xian)電(dian)(dian)纜(lan)的(de)發熱。導體電(dian)(dian)阻(zu)不(bu)合格(ge)的(de)原因，主要進企業為(wei)了(le)降低成本(ben)，將占原材(cai)(cai)料(liao)成本(ben)80%的(de)銅材(cai)(cai)縮水，要么(me)降低導體的(de)截面積，要么(me)使用含(han)雜質(zhi)過高的(de)再生銅，這樣(yang)致使電(dian)(dian)線(xian)電(dian)(dian)纜(lan)的(de)導體電(dian)(dian)阻(zu)嚴重(zhong)超標，在使用過程(cheng)中除易引發火災，還會加(jia)速包(bao)覆在電(dian)(dian)線(xian)外的(de)絕緣(yuan)層的(de)老化。

在購買電(dian)線(xian)電(dian)纜的過程(cheng)中，消(xiao)費者(zhe)應注意以(yi)下幾個事

第一、要觀察電線的(de)(de)外觀。合格(ge)產品的(de)(de)絕緣（護(hu)套）層柔軟、有韌性(xing)和伸(shen)縮(suo)性(xing)、表面層緊密、光滑(hua)、無粗糙感。如果包(bao)裹(guo)電線的(de)(de)塑(su)料很容(rong)易(yi)被(bei)剝去，則存在(zai)塑(su)料強度不夠(gou)的(de)(de)問題。

第二、要看(kan)電線的(de)截面(mian)(mian)。合(he)格產品的(de)銅(tong)(tong)芯或鋁芯表面(mian)(mian)應(ying)該具有(you)金屬光澤，表面(mian)(mian)發(fa)(fa)黑的(de)銅(tong)(tong)或表面(mian)(mian)發(fa)(fa)白的(de)鋁說(shuo)明(ming)已被氧化。

第(di)三(san)、在購(gou)買電(dian)線(xian)時應(ying)(ying)注意查看質(zhi)量(liang)合(he)格證(zheng)書。如果電(dian)線(xian)的質(zhi)量(liang)合(he)格，那么(me)其(qi)電(dian)線(xian)質(zhi)量(liang)應(ying)(ying)該(gai)也受過檢驗(yan)，不會(hui)有太大的問題(ti)。
