不(bu)合格電(dian)線電(dian)纜的危害(hai)
電(dian)線電(dian)纜是用(yong)于傳(chuan)輸(shu)電(dian)力、傳(chuan)輸(shu)信息和(he)實現電(dian)磁能量轉換的一大類電(dian)工產品。在抽(chou)查過程中(zhong)，發現了大量的不(bu)合格(ge)產品，這些(xie)劣質產品給電(dian)力系統正常(chang)運行埋下諸(zhu)多隱患。
1、標(biao)志(zhi)不合格的(de)電(dian)(dian)線(xian)電(dian)(dian)纜。標(biao)志(zhi)是電(dian)(dian)線(xian)電(dian)(dian)纜使用識別產(chan)品基(ji)本信(xin)息的(de)主(zhu)要途徑，根(gen)據(ju)標(biao)準規(gui)定標(biao)志(zhi)的(de)主(zhu)要內(nei)容(rong)是：產(chan)品型號、規(gui)格、標(biao)準號、廠名、產(chan)地等在一定的(de)標(biao)示間距內(nei)，當標(biao)志(zhi)不合格時，會(hui)造成(cheng)施工人員識別錯誤，嚴(yan)重時會(hui)引發電(dian)(dian)氣事故。
2、結構(gou)(gou)尺寸不合格的(de)電(dian)線(xian)電(dian)纜(lan)(lan)。結構(gou)(gou)尺寸的(de)主要問題是護(hu)套厚度，絕(jue)(jue)緣厚度，當電(dian)纜(lan)(lan)的(de)護(hu)套和絕(jue)(jue)緣厚度不達標(biao)時，致使電(dian)線(xian)電(dian)纜(lan)(lan)耐電(dian)氣強度會嚴(yan)重降(jiang)低(di)，導致電(dian)線(xian)電(dian)纜(lan)(lan)的(de)使用壽(shou)命(ming)縮短(duan)，嚴(yan)重時可導致電(dian)線(xian)電(dian)纜(lan)(lan)被擊穿，絕(jue)(jue)緣（護(hu)套）層(ceng)起不到正常保(bao)護(hu)作用，從(cong)而發生電(dian)氣短(duan)路和火災等現(xian)象。
3、護套式絕(jue)(jue)緣(yuan)老化前的(de)抗(kang)(kang)張強度、伸長率合格的(de)電(dian)線電(dian)纜。絕(jue)(jue)緣(yuan)護套老化前的(de)抗(kang)(kang)張強度、伸長率不(bu)合格直接大大縮短電(dian)線電(dian)纜的(de)工作用(yong)壽命，而且在施工或(huo)在長時間通電(dian)且溫度較高的(de)環境中，極易(yi)出現絕(jue)(jue)緣(yuan)體(ti)斷裂，致(zhi)使(shi)帶電(dian)導(dao)體(ti)裸露，發生能觸電(dian)式短路危險。其不(bu)合格的(de)主要原因是使(shi)用(yong)了再生料(liao)生產，以降低(di)產品成本，二是不(bu)具備生產資格小(xiao)型企業。
4、導(dao)(dao)體電(dian)(dian)(dian)阻(zu)不合格的(de)(de)電(dian)(dian)(dian)線(xian)。導(dao)(dao)體電(dian)(dian)(dian)阻(zu)主(zhu)要是考核電(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)纜(lan)的(de)(de)導(dao)(dao)體材料以及截面(mian)是否符(fu)合的(de)(de)重要指(zhi)標。當導(dao)(dao)體電(dian)(dian)(dian)阻(zu)超標時，就增(zeng)大(da)了(le)電(dian)(dian)(dian)流在線(xian)路上通過時的(de)(de)損耗，加(jia)(jia)劇了(le)電(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)纜(lan)的(de)(de)發熱(re)。導(dao)(dao)體電(dian)(dian)(dian)阻(zu)不合格的(de)(de)原因(yin)，主(zhu)要進企業為(wei)了(le)降低(di)成本(ben)，將占原材料成本(ben)80%的(de)(de)銅材縮(suo)水(shui)，要么降低(di)導(dao)(dao)體的(de)(de)截面(mian)積，要么使(shi)(shi)用含雜質過高的(de)(de)再生銅，這樣致使(shi)(shi)電(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)纜(lan)的(de)(de)導(dao)(dao)體電(dian)(dian)(dian)阻(zu)嚴重超標，在使(shi)(shi)用過程(cheng)中除易引(yin)發火災，還(huan)會(hui)加(jia)(jia)速包覆在電(dian)(dian)(dian)線(xian)外的(de)(de)絕緣層的(de)(de)老化。
在購買電線(xian)電纜(lan)的過程(cheng)中(zhong)，消費(fei)者(zhe)應注意以下幾個(ge)事
第(di)一、要觀察電線(xian)(xian)的(de)外觀。合格產品(pin)的(de)絕緣（護套）層柔軟、有韌性和伸縮性、表面層緊(jin)密(mi)、光滑、無粗糙感。如果(guo)包裹電線(xian)(xian)的(de)塑(su)料(liao)很(hen)容易被剝去，則存在(zai)塑(su)料(liao)強度(du)不夠的(de)問題。
第(di)二、要看(kan)電線的(de)截面。合格產品的(de)銅芯或(huo)鋁芯表(biao)面應該具有金屬光澤，表(biao)面發黑的(de)銅或(huo)表(biao)面發白(bai)的(de)鋁說明已(yi)被氧化。
第三、在(zai)購買電(dian)線時應注意查看質量(liang)合(he)格(ge)(ge)證書。如果電(dian)線的(de)質量(liang)合(he)格(ge)(ge)，那么其電(dian)線質量(liang)應該也(ye)受過(guo)檢驗，不會有太(tai)大的(de)問(wen)題。
