不合格電線(xian)電纜的危(wei)害

電線電纜是用于傳(chuan)輸電力(li)(li)、傳(chuan)輸信(xin)息和實現(xian)電磁能量轉換的一大(da)類(lei)電工產品。在抽查(cha)過程(cheng)中(zhong)，發現(xian)了大(da)量的不合格產品，這(zhe)些劣質產品給(gei)電力(li)(li)系統正(zheng)常運行埋下諸(zhu)多隱患(huan)。

1、標(biao)(biao)(biao)志(zhi)不(bu)(bu)合格(ge)的電(dian)線電(dian)纜。標(biao)(biao)(biao)志(zhi)是電(dian)線電(dian)纜使用識別產品(pin)基本信息(xi)的主要途(tu)徑，根(gen)據標(biao)(biao)(biao)準規定(ding)標(biao)(biao)(biao)志(zhi)的主要內(nei)容是：產品(pin)型號(hao)、規格(ge)、標(biao)(biao)(biao)準號(hao)、廠名、產地(di)等在一定(ding)的標(biao)(biao)(biao)示間距內(nei)，當標(biao)(biao)(biao)志(zhi)不(bu)(bu)合格(ge)時，會造成施工人員(yuan)識別錯誤，嚴重(zhong)時會引發電(dian)氣事故。

2、結構尺寸(cun)不(bu)合(he)格的(de)電(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)纜。結構尺寸(cun)的(de)主要問題是護套厚度(du)，絕(jue)緣(yuan)厚度(du)，當(dang)電(dian)(dian)(dian)纜的(de)護套和絕(jue)緣(yuan)厚度(du)不(bu)達標時，致使電(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)纜耐電(dian)(dian)(dian)氣強(qiang)度(du)會嚴重降低，導致電(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)纜的(de)使用壽命縮短(duan)，嚴重時可導致電(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)纜被擊穿，絕(jue)緣(yuan)（護套）層起(qi)不(bu)到正常(chang)保護作用，從而發(fa)生電(dian)(dian)(dian)氣短(duan)路和火災等(deng)現象。

3、護套式(shi)絕緣老化前的(de)抗張(zhang)強度、伸長(chang)(chang)率合(he)格(ge)(ge)的(de)電(dian)(dian)線電(dian)(dian)纜。絕緣護套老化前的(de)抗張(zhang)強度、伸長(chang)(chang)率不(bu)合(he)格(ge)(ge)直接(jie)大大縮短電(dian)(dian)線電(dian)(dian)纜的(de)工(gong)作用壽命，而(er)且在施工(gong)或在長(chang)(chang)時間(jian)通電(dian)(dian)且溫度較高(gao)的(de)環境中，極(ji)易出現絕緣體斷裂，致使(shi)帶電(dian)(dian)導(dao)體裸(luo)露，發生能觸電(dian)(dian)式(shi)短路(lu)危(wei)險。其不(bu)合(he)格(ge)(ge)的(de)主(zhu)要(yao)原因是使(shi)用了再生料生產，以降低產品(pin)成本，二是不(bu)具備生產資格(ge)(ge)小型企業。

4、導(dao)體(ti)電(dian)(dian)(dian)阻(zu)不(bu)合(he)格(ge)的(de)(de)電(dian)(dian)(dian)線(xian)。導(dao)體(ti)電(dian)(dian)(dian)阻(zu)主要是考核電(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)纜的(de)(de)導(dao)體(ti)材料以及(ji)截(jie)面(mian)是否符合(he)的(de)(de)重要指標(biao)。當(dang)導(dao)體(ti)電(dian)(dian)(dian)阻(zu)超(chao)標(biao)時，就增(zeng)大了(le)電(dian)(dian)(dian)流(liu)在(zai)線(xian)路上通過時的(de)(de)損(sun)耗，加(jia)劇了(le)電(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)纜的(de)(de)發(fa)熱。導(dao)體(ti)電(dian)(dian)(dian)阻(zu)不(bu)合(he)格(ge)的(de)(de)原(yuan)因，主要進企(qi)業(ye)為(wei)了(le)降(jiang)低成本，將占原(yuan)材料成本80%的(de)(de)銅材縮水，要么(me)降(jiang)低導(dao)體(ti)的(de)(de)截(jie)面(mian)積，要么(me)使(shi)用含雜質過高的(de)(de)再生(sheng)銅，這樣致使(shi)電(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)纜的(de)(de)導(dao)體(ti)電(dian)(dian)(dian)阻(zu)嚴(yan)重超(chao)標(biao)，在(zai)使(shi)用過程中除易引發(fa)火災，還會加(jia)速包覆在(zai)電(dian)(dian)(dian)線(xian)外(wai)的(de)(de)絕緣層的(de)(de)老化(hua)。

在(zai)購買電(dian)線電(dian)纜的(de)過程(cheng)中，消費(fei)者應注意以下幾個(ge)事(shi)

第一、要(yao)觀(guan)察(cha)電(dian)線(xian)的外觀(guan)。合格產品的絕緣（護套）層柔軟、有韌性(xing)和(he)伸縮性(xing)、表面(mian)層緊密、光滑、無粗(cu)糙(cao)感。如果(guo)包裹電(dian)線(xian)的塑料(liao)(liao)很(hen)容易被剝去，則(ze)存在塑料(liao)(liao)強度不夠的問(wen)題(ti)。

第二、要看電線的(de)截面(mian)(mian)。合格(ge)產品(pin)的(de)銅芯或鋁芯表(biao)面(mian)(mian)應該具有金屬光(guang)澤，表(biao)面(mian)(mian)發黑的(de)銅或表(biao)面(mian)(mian)發白(bai)的(de)鋁說明(ming)已被氧化。

第三(san)、在購買電線(xian)時應注意查看質量(liang)合(he)(he)格(ge)證書。如(ru)果電線(xian)的(de)質量(liang)合(he)(he)格(ge)，那么其電線(xian)質量(liang)應該也受過檢(jian)驗，不會有太大的(de)問(wen)題。
