不合(he)格電線電纜(lan)的危害(hai)

電(dian)線電(dian)纜是用于傳輸(shu)電(dian)力、傳輸(shu)信息和實現(xian)(xian)電(dian)磁能量(liang)轉換的一大(da)類電(dian)工產品。在抽查過(guo)程(cheng)中，發現(xian)(xian)了大(da)量(liang)的不合格產品，這(zhe)些劣質產品給電(dian)力系統正常運行埋下諸多隱患(huan)。

1、標(biao)志(zhi)不合格的(de)電線(xian)電纜。標(biao)志(zhi)是電線(xian)電纜使用識別產品基本(ben)信息的(de)主(zhu)要途徑，根據標(biao)準規定(ding)標(biao)志(zhi)的(de)主(zhu)要內(nei)容是：產品型號、規格、標(biao)準號、廠名、產地(di)等在一(yi)定(ding)的(de)標(biao)示間距(ju)內(nei)，當(dang)標(biao)志(zhi)不合格時，會造成施工人(ren)員識別錯誤，嚴重時會引(yin)發電氣事故。

2、結構尺(chi)寸不(bu)合格的電(dian)(dian)(dian)線電(dian)(dian)(dian)纜。結構尺(chi)寸的主要問題(ti)是護(hu)套厚(hou)度，絕緣厚(hou)度，當電(dian)(dian)(dian)纜的護(hu)套和(he)絕緣厚(hou)度不(bu)達標時，致(zhi)使電(dian)(dian)(dian)線電(dian)(dian)(dian)纜耐(nai)電(dian)(dian)(dian)氣強(qiang)度會(hui)嚴重降低，導致(zhi)電(dian)(dian)(dian)線電(dian)(dian)(dian)纜的使用壽命縮短，嚴重時可導致(zhi)電(dian)(dian)(dian)線電(dian)(dian)(dian)纜被擊穿，絕緣（護(hu)套）層起(qi)不(bu)到正常保(bao)護(hu)作用，從而(er)發生電(dian)(dian)(dian)氣短路和(he)火災等現象(xiang)。

3、護套式(shi)絕緣(yuan)老(lao)化(hua)前(qian)的(de)抗(kang)張(zhang)強度(du)(du)、伸長(chang)(chang)率合格(ge)(ge)的(de)電線(xian)電纜。絕緣(yuan)護套老(lao)化(hua)前(qian)的(de)抗(kang)張(zhang)強度(du)(du)、伸長(chang)(chang)率不合格(ge)(ge)直接(jie)大大縮短(duan)電線(xian)電纜的(de)工(gong)作用(yong)(yong)壽(shou)命，而且在(zai)施工(gong)或(huo)在(zai)長(chang)(chang)時間通電且溫度(du)(du)較高的(de)環(huan)境(jing)中，極易(yi)出現絕緣(yuan)體(ti)(ti)斷裂，致使(shi)帶電導體(ti)(ti)裸露，發生(sheng)能觸(chu)電式(shi)短(duan)路危(wei)險。其不合格(ge)(ge)的(de)主要原因是(shi)使(shi)用(yong)(yong)了(le)再生(sheng)料生(sheng)產(chan)，以降低產(chan)品成本，二是(shi)不具備生(sheng)產(chan)資格(ge)(ge)小型企(qi)業。

4、導(dao)體(ti)電(dian)阻(zu)(zu)不合(he)格(ge)的(de)電(dian)線(xian)(xian)。導(dao)體(ti)電(dian)阻(zu)(zu)主(zhu)要(yao)是(shi)考(kao)核(he)電(dian)線(xian)(xian)電(dian)纜的(de)導(dao)體(ti)材料以(yi)及截面是(shi)否(fou)符(fu)合(he)的(de)重(zhong)(zhong)要(yao)指標。當導(dao)體(ti)電(dian)阻(zu)(zu)超(chao)標時，就增(zeng)大(da)了電(dian)流在線(xian)(xian)路(lu)上(shang)通過(guo)時的(de)損耗，加劇了電(dian)線(xian)(xian)電(dian)纜的(de)發(fa)熱。導(dao)體(ti)電(dian)阻(zu)(zu)不合(he)格(ge)的(de)原(yuan)因，主(zhu)要(yao)進(jin)企業為了降(jiang)(jiang)低(di)成本，將占原(yuan)材料成本80%的(de)銅(tong)材縮(suo)水，要(yao)么降(jiang)(jiang)低(di)導(dao)體(ti)的(de)截面積，要(yao)么使用(yong)含雜質(zhi)過(guo)高的(de)再生銅(tong)，這樣致使電(dian)線(xian)(xian)電(dian)纜的(de)導(dao)體(ti)電(dian)阻(zu)(zu)嚴重(zhong)(zhong)超(chao)標，在使用(yong)過(guo)程中除(chu)易(yi)引發(fa)火(huo)災，還會加速包覆在電(dian)線(xian)(xian)外的(de)絕緣層的(de)老化。

在購(gou)買電線電纜(lan)的過程中(zhong)，消費(fei)者(zhe)應(ying)注意以下幾個事

第一(yi)、要觀察電線的外觀。合格產品的絕緣（護(hu)套）層柔軟、有韌性(xing)和(he)伸縮性(xing)、表面層緊密、光滑、無粗糙感。如果包裹電線的塑(su)料(liao)很容易(yi)被(bei)剝(bo)去，則存在塑(su)料(liao)強度不夠(gou)的問題。

第(di)二、要看電線的截面(mian)。合(he)格產品的銅(tong)芯或(huo)鋁(lv)芯表(biao)面(mian)應該具有金屬(shu)光澤，表(biao)面(mian)發(fa)黑的銅(tong)或(huo)表(biao)面(mian)發(fa)白(bai)的鋁(lv)說明已被氧(yang)化。

第三(san)、在(zai)購買電(dian)(dian)線時應(ying)注意查看質量(liang)合(he)格證書(shu)。如果電(dian)(dian)線的質量(liang)合(he)格，那么其電(dian)(dian)線質量(liang)應(ying)該也受過檢驗，不會(hui)有太大的問題。
