不合格(ge)電(dian)線電(dian)纜的危害

電(dian)(dian)線(xian)電(dian)(dian)纜是用于傳輸(shu)電(dian)(dian)力(li)、傳輸(shu)信息和實現電(dian)(dian)磁(ci)能量(liang)轉換的一大類電(dian)(dian)工(gong)產品。在抽查過程中，發(fa)現了大量(liang)的不合格產品，這些劣質產品給電(dian)(dian)力(li)系統正常運行埋(mai)下(xia)諸多隱(yin)患(huan)。

1、標志(zhi)(zhi)不合格的電(dian)線(xian)電(dian)纜(lan)。標志(zhi)(zhi)是電(dian)線(xian)電(dian)纜(lan)使用識(shi)(shi)別產品(pin)基(ji)本信息的主要(yao)途徑，根據標準規定(ding)標志(zhi)(zhi)的主要(yao)內(nei)(nei)容是：產品(pin)型號、規格、標準號、廠名、產地(di)等在一定(ding)的標示間距內(nei)(nei)，當標志(zhi)(zhi)不合格時，會(hui)造成施工人(ren)員識(shi)(shi)別錯誤，嚴(yan)重時會(hui)引發電(dian)氣(qi)事故。

2、結(jie)構尺寸不(bu)合格的(de)電(dian)線電(dian)纜。結(jie)構尺寸的(de)主(zhu)要問題(ti)是護(hu)套(tao)厚(hou)(hou)度(du)(du)，絕緣(yuan)厚(hou)(hou)度(du)(du)，當電(dian)纜的(de)護(hu)套(tao)和絕緣(yuan)厚(hou)(hou)度(du)(du)不(bu)達標時，致(zhi)使電(dian)線電(dian)纜耐電(dian)氣強度(du)(du)會嚴重(zhong)降低，導致(zhi)電(dian)線電(dian)纜的(de)使用壽命縮短，嚴重(zhong)時可(ke)導致(zhi)電(dian)線電(dian)纜被(bei)擊穿，絕緣(yuan)（護(hu)套(tao)）層起不(bu)到正常保護(hu)作用，從而(er)發生電(dian)氣短路和火災等現象(xiang)。

3、護(hu)套(tao)(tao)式絕(jue)緣(yuan)(yuan)老(lao)化前的(de)(de)抗(kang)張(zhang)強度、伸長(chang)(chang)率(lv)合(he)格(ge)(ge)的(de)(de)電(dian)線電(dian)纜(lan)。絕(jue)緣(yuan)(yuan)護(hu)套(tao)(tao)老(lao)化前的(de)(de)抗(kang)張(zhang)強度、伸長(chang)(chang)率(lv)不合(he)格(ge)(ge)直接大大縮短(duan)電(dian)線電(dian)纜(lan)的(de)(de)工(gong)作用(yong)壽命，而且在施工(gong)或在長(chang)(chang)時(shi)間通電(dian)且溫(wen)度較高的(de)(de)環境中(zhong)，極易出現絕(jue)緣(yuan)(yuan)體斷裂，致(zhi)使(shi)帶電(dian)導體裸露(lu)，發生(sheng)能觸電(dian)式短(duan)路(lu)危險。其(qi)不合(he)格(ge)(ge)的(de)(de)主要原因是(shi)使(shi)用(yong)了(le)再生(sheng)料生(sheng)產，以(yi)降(jiang)低(di)產品成本，二是(shi)不具備生(sheng)產資格(ge)(ge)小(xiao)型企業。

4、導體(ti)(ti)電(dian)(dian)(dian)(dian)阻(zu)不合格的(de)(de)(de)(de)電(dian)(dian)(dian)(dian)線。導體(ti)(ti)電(dian)(dian)(dian)(dian)阻(zu)主要(yao)是考核電(dian)(dian)(dian)(dian)線電(dian)(dian)(dian)(dian)纜的(de)(de)(de)(de)導體(ti)(ti)材(cai)料以及截(jie)面是否(fou)符(fu)合的(de)(de)(de)(de)重(zhong)要(yao)指(zhi)標。當導體(ti)(ti)電(dian)(dian)(dian)(dian)阻(zu)超(chao)標時，就增(zeng)大了(le)電(dian)(dian)(dian)(dian)流在(zai)線路上通過時的(de)(de)(de)(de)損耗(hao)，加劇(ju)了(le)電(dian)(dian)(dian)(dian)線電(dian)(dian)(dian)(dian)纜的(de)(de)(de)(de)發(fa)熱。導體(ti)(ti)電(dian)(dian)(dian)(dian)阻(zu)不合格的(de)(de)(de)(de)原因，主要(yao)進(jin)企業為了(le)降(jiang)低成本，將(jiang)占原材(cai)料成本80%的(de)(de)(de)(de)銅材(cai)縮水，要(yao)么降(jiang)低導體(ti)(ti)的(de)(de)(de)(de)截(jie)面積，要(yao)么使(shi)用含雜質過高的(de)(de)(de)(de)再生銅，這樣致使(shi)電(dian)(dian)(dian)(dian)線電(dian)(dian)(dian)(dian)纜的(de)(de)(de)(de)導體(ti)(ti)電(dian)(dian)(dian)(dian)阻(zu)嚴重(zhong)超(chao)標，在(zai)使(shi)用過程中除(chu)易引發(fa)火災(zai)，還會加速包覆在(zai)電(dian)(dian)(dian)(dian)線外的(de)(de)(de)(de)絕緣(yuan)層(ceng)的(de)(de)(de)(de)老化。

在購買(mai)電(dian)線電(dian)纜的過(guo)程中，消費者應(ying)注(zhu)意以下幾(ji)個(ge)事

第一、要觀(guan)察(cha)電線的外觀(guan)。合(he)格(ge)產品的絕(jue)緣（護套(tao)）層柔(rou)軟、有韌性(xing)和伸縮性(xing)、表面層緊密、光滑、無粗糙(cao)感。如果包裹(guo)電線的塑(su)料很容易(yi)被(bei)剝去(qu)，則存在塑(su)料強度不夠的問題(ti)。

第二、要(yao)看電線的(de)(de)截(jie)面(mian)(mian)。合格產(chan)品的(de)(de)銅芯或鋁芯表(biao)面(mian)(mian)應該具有金屬光澤，表(biao)面(mian)(mian)發黑的(de)(de)銅或表(biao)面(mian)(mian)發白的(de)(de)鋁說明已被氧化。

第三(san)、在購(gou)買電線(xian)時應注意查看質量合格(ge)(ge)證書(shu)。如果電線(xian)的質量合格(ge)(ge)，那(nei)么其電線(xian)質量應該也受過檢驗，不會有太大的問題。
