不合格電線電纜的(de)危害(hai)
電(dian)線電(dian)纜(lan)是(shi)用于傳(chuan)輸電(dian)力、傳(chuan)輸信息和(he)實現電(dian)磁能量轉換的一大類電(dian)工產(chan)品(pin)(pin)。在抽查過(guo)程中，發現了大量的不合格(ge)產(chan)品(pin)(pin)，這些劣質產(chan)品(pin)(pin)給電(dian)力系統正常運行埋(mai)下諸多隱患(huan)。
1、標志(zhi)不(bu)合格的(de)(de)電(dian)線(xian)電(dian)纜。標志(zhi)是電(dian)線(xian)電(dian)纜使用識別產(chan)(chan)品(pin)基本信息的(de)(de)主要(yao)途徑(jing)，根據標準規(gui)定標志(zhi)的(de)(de)主要(yao)內(nei)容是：產(chan)(chan)品(pin)型號(hao)、規(gui)格、標準號(hao)、廠名、產(chan)(chan)地等在一定的(de)(de)標示(shi)間距內(nei)，當標志(zhi)不(bu)合格時(shi)，會造成施工人員識別錯誤，嚴重時(shi)會引發電(dian)氣事故。
2、結(jie)構尺寸不(bu)合格(ge)的(de)(de)電(dian)線電(dian)纜。結(jie)構尺寸的(de)(de)主要問(wen)題是(shi)護(hu)套厚(hou)度，絕緣(yuan)厚(hou)度，當電(dian)纜的(de)(de)護(hu)套和絕緣(yuan)厚(hou)度不(bu)達(da)標(biao)時(shi)，致使電(dian)線電(dian)纜耐(nai)電(dian)氣強度會嚴重降低，導致電(dian)線電(dian)纜的(de)(de)使用壽命(ming)縮短，嚴重時(shi)可導致電(dian)線電(dian)纜被擊穿，絕緣(yuan)（護(hu)套）層起不(bu)到正常保護(hu)作用，從而發生電(dian)氣短路和火災(zai)等現象。
3、護(hu)套式絕緣老(lao)化(hua)前的(de)(de)(de)抗(kang)張強度、伸長(chang)(chang)率(lv)合(he)格(ge)的(de)(de)(de)電(dian)(dian)線電(dian)(dian)纜。絕緣護(hu)套老(lao)化(hua)前的(de)(de)(de)抗(kang)張強度、伸長(chang)(chang)率(lv)不合(he)格(ge)直接大大縮短電(dian)(dian)線電(dian)(dian)纜的(de)(de)(de)工(gong)作用壽命(ming)，而且(qie)在(zai)施工(gong)或在(zai)長(chang)(chang)時間通電(dian)(dian)且(qie)溫度較高(gao)的(de)(de)(de)環境中，極易(yi)出現絕緣體(ti)斷裂，致(zhi)使(shi)帶(dai)電(dian)(dian)導(dao)體(ti)裸露，發生(sheng)能觸電(dian)(dian)式短路危險。其不合(he)格(ge)的(de)(de)(de)主要原因(yin)是使(shi)用了再生(sheng)料生(sheng)產(chan)，以降低產(chan)品(pin)成本，二是不具(ju)備生(sheng)產(chan)資格(ge)小型企業。
4、導(dao)(dao)體電(dian)(dian)(dian)(dian)阻(zu)不合(he)(he)格(ge)的(de)(de)(de)(de)電(dian)(dian)(dian)(dian)線。導(dao)(dao)體電(dian)(dian)(dian)(dian)阻(zu)主要(yao)(yao)是考核電(dian)(dian)(dian)(dian)線電(dian)(dian)(dian)(dian)纜(lan)的(de)(de)(de)(de)導(dao)(dao)體材料以及截面是否(fou)符合(he)(he)的(de)(de)(de)(de)重要(yao)(yao)指標。當導(dao)(dao)體電(dian)(dian)(dian)(dian)阻(zu)超標時(shi)，就增大(da)了電(dian)(dian)(dian)(dian)流在(zai)線路上通過時(shi)的(de)(de)(de)(de)損耗，加(jia)劇了電(dian)(dian)(dian)(dian)線電(dian)(dian)(dian)(dian)纜(lan)的(de)(de)(de)(de)發熱。導(dao)(dao)體電(dian)(dian)(dian)(dian)阻(zu)不合(he)(he)格(ge)的(de)(de)(de)(de)原因，主要(yao)(yao)進(jin)企業為了降低成本，將(jiang)占原材料成本80%的(de)(de)(de)(de)銅(tong)材縮水，要(yao)(yao)么降低導(dao)(dao)體的(de)(de)(de)(de)截面積，要(yao)(yao)么使用(yong)含雜質過高的(de)(de)(de)(de)再生銅(tong)，這樣致使電(dian)(dian)(dian)(dian)線電(dian)(dian)(dian)(dian)纜(lan)的(de)(de)(de)(de)導(dao)(dao)體電(dian)(dian)(dian)(dian)阻(zu)嚴重超標，在(zai)使用(yong)過程中除易引發火災，還會(hui)加(jia)速包覆在(zai)電(dian)(dian)(dian)(dian)線外的(de)(de)(de)(de)絕緣(yuan)層的(de)(de)(de)(de)老化。
在購買電線電纜的(de)過程中，消費者應注(zhu)意以(yi)下幾個事(shi)
第一、要觀察(cha)電線(xian)的(de)外觀。合格產品的(de)絕緣(yuan)（護(hu)套）層柔軟、有韌(ren)性和伸縮性、表面層緊密、光滑、無粗(cu)糙感。如果包裹電線(xian)的(de)塑(su)(su)料很容(rong)易被(bei)剝去，則存在(zai)塑(su)(su)料強度不(bu)夠(gou)的(de)問題。
第二、要看電(dian)線(xian)的(de)截面(mian)。合格產品的(de)銅(tong)芯(xin)或(huo)鋁(lv)芯(xin)表(biao)(biao)面(mian)應該具有金屬(shu)光(guang)澤，表(biao)(biao)面(mian)發黑的(de)銅(tong)或(huo)表(biao)(biao)面(mian)發白(bai)的(de)鋁(lv)說明(ming)已被氧化。
第三、在購買(mai)電線時(shi)應(ying)注意查看質(zhi)量(liang)合格證(zheng)書。如果(guo)電線的質(zhi)量(liang)合格，那么其電線質(zhi)量(liang)應(ying)該也受過檢驗(yan)，不會有太大的問題。
