不合格電(dian)(dian)線(xian)電(dian)(dian)纜的危(wei)害

電(dian)線(xian)電(dian)纜是用于傳輸(shu)電(dian)力、傳輸(shu)信息和(he)實現電(dian)磁能量轉換的一(yi)大類電(dian)工產品。在(zai)抽查過(guo)程中(zhong)，發現了大量的不合格產品，這些(xie)劣質產品給(gei)電(dian)力系統正常運(yun)行埋下諸多隱(yin)患。

1、標(biao)(biao)(biao)志(zhi)不合(he)格的電線電纜。標(biao)(biao)(biao)志(zhi)是(shi)電線電纜使用識(shi)別(bie)產(chan)(chan)品基本信息的主要(yao)(yao)途徑，根據標(biao)(biao)(biao)準(zhun)(zhun)規(gui)定(ding)標(biao)(biao)(biao)志(zhi)的主要(yao)(yao)內(nei)(nei)容是(shi)：產(chan)(chan)品型號、規(gui)格、標(biao)(biao)(biao)準(zhun)(zhun)號、廠名、產(chan)(chan)地(di)等在一定(ding)的標(biao)(biao)(biao)示間距內(nei)(nei)，當標(biao)(biao)(biao)志(zhi)不合(he)格時(shi)(shi)，會(hui)造成施工(gong)人(ren)員識(shi)別(bie)錯誤，嚴重時(shi)(shi)會(hui)引發電氣事故。

2、結(jie)構尺(chi)寸不合(he)格(ge)的(de)電(dian)(dian)(dian)(dian)線電(dian)(dian)(dian)(dian)纜。結(jie)構尺(chi)寸的(de)主要問(wen)題(ti)是護(hu)套(tao)厚度，絕緣厚度，當電(dian)(dian)(dian)(dian)纜的(de)護(hu)套(tao)和(he)絕緣厚度不達(da)標時，致使電(dian)(dian)(dian)(dian)線電(dian)(dian)(dian)(dian)纜耐電(dian)(dian)(dian)(dian)氣強(qiang)度會嚴重降低，導致電(dian)(dian)(dian)(dian)線電(dian)(dian)(dian)(dian)纜的(de)使用壽(shou)命縮短(duan)，嚴重時可導致電(dian)(dian)(dian)(dian)線電(dian)(dian)(dian)(dian)纜被擊穿，絕緣（護(hu)套(tao)）層起(qi)不到(dao)正常保護(hu)作(zuo)用，從而發生電(dian)(dian)(dian)(dian)氣短(duan)路和(he)火(huo)災等現象。

3、護套式絕緣老化前的(de)(de)抗(kang)張(zhang)強(qiang)度、伸長(chang)率合格的(de)(de)電(dian)線電(dian)纜。絕緣護套老化前的(de)(de)抗(kang)張(zhang)強(qiang)度、伸長(chang)率不(bu)合格直接大(da)大(da)縮短(duan)電(dian)線電(dian)纜的(de)(de)工(gong)作用壽命，而且在(zai)施工(gong)或在(zai)長(chang)時間通電(dian)且溫度較高的(de)(de)環境中，極易(yi)出現絕緣體(ti)斷裂，致使(shi)帶電(dian)導體(ti)裸露，發生(sheng)能觸電(dian)式短(duan)路危(wei)險。其不(bu)合格的(de)(de)主要(yao)原因是使(shi)用了再生(sheng)料生(sheng)產，以降(jiang)低(di)產品成本，二是不(bu)具備生(sheng)產資格小型企業。

4、導(dao)(dao)體(ti)(ti)(ti)電(dian)(dian)阻不合格的電(dian)(dian)線。導(dao)(dao)體(ti)(ti)(ti)電(dian)(dian)阻主(zhu)(zhu)要是(shi)考核(he)電(dian)(dian)線電(dian)(dian)纜(lan)的導(dao)(dao)體(ti)(ti)(ti)材料(liao)以(yi)及截(jie)面(mian)是(shi)否符合的重要指標(biao)(biao)。當導(dao)(dao)體(ti)(ti)(ti)電(dian)(dian)阻超標(biao)(biao)時(shi)(shi)，就增大(da)了(le)(le)電(dian)(dian)流在(zai)線路上通過(guo)時(shi)(shi)的損耗，加劇了(le)(le)電(dian)(dian)線電(dian)(dian)纜(lan)的發熱。導(dao)(dao)體(ti)(ti)(ti)電(dian)(dian)阻不合格的原(yuan)因(yin)，主(zhu)(zhu)要進企業(ye)為(wei)了(le)(le)降低成(cheng)本，將(jiang)占原(yuan)材料(liao)成(cheng)本80%的銅材縮水(shui)，要么(me)降低導(dao)(dao)體(ti)(ti)(ti)的截(jie)面(mian)積，要么(me)使用含(han)雜質過(guo)高的再生銅，這樣致使電(dian)(dian)線電(dian)(dian)纜(lan)的導(dao)(dao)體(ti)(ti)(ti)電(dian)(dian)阻嚴重超標(biao)(biao)，在(zai)使用過(guo)程中除(chu)易引(yin)發火災，還會加速包(bao)覆(fu)在(zai)電(dian)(dian)線外的絕緣層的老(lao)化。

在購買電線電纜的過程中，消費(fei)者應注意以下幾個事

第一、要觀察(cha)電線的外(wai)觀。合格產品的絕緣（護(hu)套）層(ceng)柔軟、有韌性(xing)和(he)伸縮性(xing)、表面層(ceng)緊密、光滑(hua)、無(wu)粗糙感。如果包裹電線的塑料(liao)很容易被剝去，則存在塑料(liao)強(qiang)度不夠(gou)的問題。

第(di)二、要(yao)看(kan)電線的截面(mian)。合格產品的銅芯或鋁芯表(biao)面(mian)應(ying)該具有金(jin)屬(shu)光澤，表(biao)面(mian)發(fa)黑的銅或表(biao)面(mian)發(fa)白的鋁說明已(yi)被氧化。

第三、在購買電線時應注意查看(kan)質量(liang)合(he)格(ge)(ge)證(zheng)書。如(ru)果電線的(de)質量(liang)合(he)格(ge)(ge)，那么其電線質量(liang)應該也受過檢驗，不會(hui)有太大的(de)問題。
