不合(he)格電(dian)線(xian)電(dian)纜的危害(hai)

電線電纜(lan)是用于傳(chuan)輸電力、傳(chuan)輸信息和實現電磁能量轉換的(de)一大類電工產品(pin)。在抽(chou)查過程中，發現了(le)大量的(de)不合格產品(pin)，這些劣質產品(pin)給電力系統(tong)正(zheng)常運行埋下諸(zhu)多隱患。

1、標(biao)志不合格(ge)的(de)電(dian)線電(dian)纜(lan)。標(biao)志是電(dian)線電(dian)纜(lan)使(shi)用識(shi)別(bie)產品基本信息(xi)的(de)主要途徑，根據(ju)標(biao)準規(gui)定標(biao)志的(de)主要內容是：產品型號、規(gui)格(ge)、標(biao)準號、廠名(ming)、產地等(deng)在一(yi)定的(de)標(biao)示間距(ju)內，當標(biao)志不合格(ge)時，會(hui)造(zao)成施工人員識(shi)別(bie)錯誤(wu)，嚴重時會(hui)引發電(dian)氣事故。

2、結(jie)構尺寸不合格的(de)(de)電(dian)(dian)線(xian)電(dian)(dian)纜(lan)。結(jie)構尺寸的(de)(de)主要問(wen)題是護套厚(hou)(hou)度，絕(jue)緣厚(hou)(hou)度，當電(dian)(dian)纜(lan)的(de)(de)護套和絕(jue)緣厚(hou)(hou)度不達標時，致使電(dian)(dian)線(xian)電(dian)(dian)纜(lan)耐(nai)電(dian)(dian)氣強度會(hui)嚴重降低，導致電(dian)(dian)線(xian)電(dian)(dian)纜(lan)的(de)(de)使用壽命縮(suo)短(duan)，嚴重時可導致電(dian)(dian)線(xian)電(dian)(dian)纜(lan)被擊穿，絕(jue)緣（護套）層起不到正(zheng)常保護作用，從而發生(sheng)電(dian)(dian)氣短(duan)路和火災等現(xian)象。

3、護套式(shi)絕緣老化前的(de)(de)抗張(zhang)強度(du)(du)、伸長(chang)(chang)率合格的(de)(de)電(dian)(dian)線電(dian)(dian)纜。絕緣護套老化前的(de)(de)抗張(zhang)強度(du)(du)、伸長(chang)(chang)率不合格直接(jie)大大縮(suo)短(duan)電(dian)(dian)線電(dian)(dian)纜的(de)(de)工(gong)(gong)作用壽命，而且在(zai)施工(gong)(gong)或在(zai)長(chang)(chang)時(shi)間通電(dian)(dian)且溫度(du)(du)較(jiao)高的(de)(de)環境中，極易出現絕緣體斷裂(lie)，致使帶電(dian)(dian)導體裸露(lu)，發(fa)生能觸電(dian)(dian)式(shi)短(duan)路危險。其不合格的(de)(de)主要原因是使用了(le)再生料(liao)生產，以降低產品(pin)成本(ben)，二是不具(ju)備生產資(zi)格小型企(qi)業。

4、導(dao)(dao)體(ti)(ti)電(dian)(dian)(dian)(dian)(dian)阻(zu)不(bu)合(he)格(ge)的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)線。導(dao)(dao)體(ti)(ti)電(dian)(dian)(dian)(dian)(dian)阻(zu)主(zhu)要(yao)是考核電(dian)(dian)(dian)(dian)(dian)線電(dian)(dian)(dian)(dian)(dian)纜的(de)(de)(de)導(dao)(dao)體(ti)(ti)材(cai)料以及(ji)截(jie)面是否符(fu)合(he)的(de)(de)(de)重要(yao)指標(biao)。當導(dao)(dao)體(ti)(ti)電(dian)(dian)(dian)(dian)(dian)阻(zu)超(chao)標(biao)時，就增大了電(dian)(dian)(dian)(dian)(dian)流在線路上通過(guo)時的(de)(de)(de)損耗(hao)，加劇了電(dian)(dian)(dian)(dian)(dian)線電(dian)(dian)(dian)(dian)(dian)纜的(de)(de)(de)發(fa)熱(re)。導(dao)(dao)體(ti)(ti)電(dian)(dian)(dian)(dian)(dian)阻(zu)不(bu)合(he)格(ge)的(de)(de)(de)原因(yin)，主(zhu)要(yao)進企業為了降低(di)成本(ben)，將(jiang)占原材(cai)料成本(ben)80%的(de)(de)(de)銅材(cai)縮水(shui)，要(yao)么降低(di)導(dao)(dao)體(ti)(ti)的(de)(de)(de)截(jie)面積(ji)，要(yao)么使(shi)用含雜質過(guo)高的(de)(de)(de)再生銅，這樣致使(shi)電(dian)(dian)(dian)(dian)(dian)線電(dian)(dian)(dian)(dian)(dian)纜的(de)(de)(de)導(dao)(dao)體(ti)(ti)電(dian)(dian)(dian)(dian)(dian)阻(zu)嚴重超(chao)標(biao)，在使(shi)用過(guo)程中除易(yi)引發(fa)火(huo)災，還會加速包覆在電(dian)(dian)(dian)(dian)(dian)線外的(de)(de)(de)絕(jue)緣層(ceng)的(de)(de)(de)老化。

在購買(mai)電(dian)線電(dian)纜的過程中(zhong)，消費者應注意以(yi)下幾個事

第(di)一、要觀(guan)察(cha)電(dian)線(xian)的(de)(de)外(wai)觀(guan)。合格產品的(de)(de)絕緣（護(hu)套）層(ceng)柔軟、有韌性和(he)伸縮性、表面層(ceng)緊密(mi)、光滑、無粗糙感。如(ru)果包(bao)裹電(dian)線(xian)的(de)(de)塑(su)料很容易被剝去，則存在(zai)塑(su)料強度(du)不夠的(de)(de)問題(ti)。

第二、要看(kan)電線(xian)的(de)截面。合格(ge)產品的(de)銅(tong)芯或鋁芯表(biao)面應該(gai)具有金屬(shu)光(guang)澤，表(biao)面發黑的(de)銅(tong)或表(biao)面發白的(de)鋁說明(ming)已被氧化(hua)。

第三(san)、在(zai)購(gou)買(mai)電(dian)線時應(ying)注意查看質(zhi)量(liang)合格證書。如果電(dian)線的質(zhi)量(liang)合格，那么其電(dian)線質(zhi)量(liang)應(ying)該也受過檢驗，不會有(you)太大的問題。
