不合格電線電纜(lan)的危害

電(dian)(dian)線電(dian)(dian)纜是用于(yu)傳(chuan)輸電(dian)(dian)力(li)、傳(chuan)輸信(xin)息(xi)和(he)實現電(dian)(dian)磁能(neng)量轉換的一大類電(dian)(dian)工產(chan)品(pin)。在(zai)抽查(cha)過(guo)程中，發(fa)現了大量的不合格產(chan)品(pin)，這(zhe)些劣(lie)質產(chan)品(pin)給(gei)電(dian)(dian)力(li)系(xi)統正(zheng)常運行(xing)埋(mai)下諸多隱(yin)患(huan)。

1、標(biao)志(zhi)不(bu)合格的電線(xian)電纜(lan)。標(biao)志(zhi)是(shi)電線(xian)電纜(lan)使用(yong)識別產(chan)(chan)品(pin)(pin)基本信(xin)息的主(zhu)要(yao)途徑，根據標(biao)準(zhun)規定標(biao)志(zhi)的主(zhu)要(yao)內容是(shi)：產(chan)(chan)品(pin)(pin)型(xing)號(hao)、規格、標(biao)準(zhun)號(hao)、廠名(ming)、產(chan)(chan)地(di)等在一定的標(biao)示間距內，當標(biao)志(zhi)不(bu)合格時，會(hui)造成施工人員識別錯(cuo)誤，嚴重時會(hui)引發電氣事故(gu)。

2、結(jie)構(gou)尺寸不合格的電(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)纜。結(jie)構(gou)尺寸的主(zhu)要問題是護(hu)套厚(hou)度(du)(du)，絕緣(yuan)厚(hou)度(du)(du)，當電(dian)(dian)(dian)纜的護(hu)套和(he)絕緣(yuan)厚(hou)度(du)(du)不達標(biao)時，致使電(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)纜耐電(dian)(dian)(dian)氣強(qiang)度(du)(du)會嚴重降低，導致電(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)纜的使用壽命(ming)縮短(duan)，嚴重時可導致電(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)纜被擊穿(chuan)，絕緣(yuan)（護(hu)套）層起(qi)不到正常保(bao)護(hu)作用，從(cong)而發生電(dian)(dian)(dian)氣短(duan)路(lu)和(he)火災(zai)等(deng)現象。

3、護(hu)套式絕(jue)緣老化前的(de)抗張(zhang)強(qiang)度、伸長(chang)率合格(ge)(ge)的(de)電線(xian)電纜(lan)。絕(jue)緣護(hu)套老化前的(de)抗張(zhang)強(qiang)度、伸長(chang)率不合格(ge)(ge)直接大大縮短電線(xian)電纜(lan)的(de)工作用(yong)(yong)壽命(ming)，而且在(zai)施(shi)工或在(zai)長(chang)時間通電且溫度較(jiao)高的(de)環境(jing)中，極易出現絕(jue)緣體斷裂，致使帶電導體裸露，發生(sheng)(sheng)能觸電式短路(lu)危險。其不合格(ge)(ge)的(de)主(zhu)要原因是(shi)使用(yong)(yong)了再生(sheng)(sheng)料生(sheng)(sheng)產(chan)(chan)，以降低產(chan)(chan)品(pin)成本，二是(shi)不具備生(sheng)(sheng)產(chan)(chan)資格(ge)(ge)小型企業(ye)。

4、導(dao)(dao)體(ti)電(dian)(dian)(dian)(dian)(dian)阻(zu)不合(he)格(ge)的(de)(de)電(dian)(dian)(dian)(dian)(dian)線(xian)(xian)。導(dao)(dao)體(ti)電(dian)(dian)(dian)(dian)(dian)阻(zu)主要(yao)是考核(he)電(dian)(dian)(dian)(dian)(dian)線(xian)(xian)電(dian)(dian)(dian)(dian)(dian)纜的(de)(de)導(dao)(dao)體(ti)材料(liao)以及截(jie)面是否(fou)符合(he)的(de)(de)重要(yao)指標。當導(dao)(dao)體(ti)電(dian)(dian)(dian)(dian)(dian)阻(zu)超標時，就增(zeng)大了(le)(le)電(dian)(dian)(dian)(dian)(dian)流在線(xian)(xian)路(lu)上通過時的(de)(de)損(sun)耗(hao)，加劇了(le)(le)電(dian)(dian)(dian)(dian)(dian)線(xian)(xian)電(dian)(dian)(dian)(dian)(dian)纜的(de)(de)發熱。導(dao)(dao)體(ti)電(dian)(dian)(dian)(dian)(dian)阻(zu)不合(he)格(ge)的(de)(de)原因(yin)，主要(yao)進企業為(wei)了(le)(le)降低成(cheng)本，將占(zhan)原材料(liao)成(cheng)本80%的(de)(de)銅材縮水，要(yao)么(me)降低導(dao)(dao)體(ti)的(de)(de)截(jie)面積，要(yao)么(me)使用含雜(za)質(zhi)過高的(de)(de)再生銅，這樣致(zhi)使電(dian)(dian)(dian)(dian)(dian)線(xian)(xian)電(dian)(dian)(dian)(dian)(dian)纜的(de)(de)導(dao)(dao)體(ti)電(dian)(dian)(dian)(dian)(dian)阻(zu)嚴重超標，在使用過程中除易(yi)引發火災，還會加速包覆在電(dian)(dian)(dian)(dian)(dian)線(xian)(xian)外(wai)的(de)(de)絕緣(yuan)層的(de)(de)老化。

在購買電線電纜的過程(cheng)中，消費者應注(zhu)意以下幾個事(shi)

第一、要觀察電(dian)線的(de)外觀。合格產品(pin)的(de)絕(jue)緣(yuan)（護套）層柔軟、有韌性和伸縮性、表面層緊(jin)密(mi)、光(guang)滑、無粗糙感。如果(guo)包裹(guo)電(dian)線的(de)塑料(liao)很容(rong)易被剝去，則存在(zai)塑料(liao)強度(du)不(bu)夠(gou)的(de)問題(ti)。

第二、要看(kan)電線的截面(mian)。合格產品的銅芯或(huo)鋁芯表面(mian)應該(gai)具有金屬光澤，表面(mian)發黑(hei)的銅或(huo)表面(mian)發白的鋁說明已(yi)被氧化(hua)。

第(di)三(san)、在購買(mai)電線(xian)(xian)時(shi)應注意查看質量(liang)合(he)格(ge)證書(shu)。如果電線(xian)(xian)的(de)質量(liang)合(he)格(ge)，那么其電線(xian)(xian)質量(liang)應該也受過檢驗，不(bu)會有太(tai)大的(de)問題。
