電線電纜品牌廠家介紹常見的電纜故障

電線(xian)(xian)表(biao)面標志(zhi)——根據國家標準規定(ding)(ding)，電線(xian)(xian)表(biao)面應(ying)有制造(zao)廠(chang)名(ming)、產(chan)品(pin)型號和額(e)(e)定(ding)(ding)電壓的(de)連續標志(zhi)。這有利(li)于在電線(xian)(xian)使用過程中發生問題時(shi)(shi)能及時(shi)(shi)找到(dao)制造(zao)廠(chang)，消費(fei)者在選(xuan)(xuan)購電線(xian)(xian)時(shi)(shi)務必注(zhu)意(yi)這一點。同時(shi)(shi)消費(fei)者在選(xuan)(xuan)購電線(xian)(xian)時(shi)(shi)應(ying)注(zhu)意(yi)合格證上標明的(de)制造(zao)廠(chang)名(ming)、產(chan)品(pin)型號、額(e)(e)定(ding)(ding)電壓與(yu)電線(xian)(xian)表(biao)面的(de)印刷標志(zhi)是(shi)否一致(zhi)，防(fang)止冒(mao)牌(pai)產(chan)品(pin)。

電線(xian)(xian)外(wai)觀——消(xiao)費者(zhe)在選購(gou)電線(xian)(xian)時應(ying)注意(yi)電線(xian)(xian)的外(wai)觀應(ying)光滑平整，絕緣(yuan)和護套(tao)層(ceng)無損壞，標志印字(zi)清晰，手模電線(xian)(xian)時無油膩感。從電線(xian)(xian)的橫截(jie)面看，電線(xian)(xian)的整個圓(yuan)周上絕緣(yuan)或(huo)護套(tao)的厚度應(ying)均勻(yun)，不應(ying)偏芯(xin)，絕緣(yuan)或(huo)護套(tao)應(ying)有(you)一定的厚度。

導體(ti)線(xian)徑——消(xiao)費者(zhe)在(zai)選購電(dian)(dian)線(xian)時應注意導體(ti)線(xian)徑是否(fou)與合格證(zheng)上明示的(de)(de)截面(mian)相符，若導體(ti)截面(mian)偏(pian)小，容易使電(dian)(dian)線(xian)發(fa)熱(re)引起(qi)短路。建議家庭(ting)照明線(xian)路用(yong)電(dian)(dian)線(xian)采(cai)用(yong)1.5平(ping)方毫米及(ji)(ji)以上規格；空調、微波(bo)爐(lu)等用(yong)功率較大的(de)(de)家用(yong)電(dian)(dian)器應采(cai)用(yong)2.5平(ping)方毫米及(ji)(ji)以上規格的(de)(de)電(dian)(dian)線(xian)。

規范(fan)(fan)使用(yong)(yong)——應(ying)規范(fan)(fan)布(bu)線(xian)(xian)(xian)(xian)(xian)，固定線(xian)(xian)(xian)(xian)(xian)路采用(yong)(yong)BV單(dan)芯線(xian)(xian)(xian)(xian)(xian)穿管(guan)子，注意在(zai)(zai)布(bu)線(xian)(xian)(xian)(xian)(xian)時(shi)不(bu)要(yao)碰(peng)(peng)壞(huai)電(dian)(dian)(dian)(dian)線(xian)(xian)(xian)(xian)(xian),在(zai)(zai)房間(jian)裝潢時(shi)不(bu)要(yao)碰(peng)(peng)壞(huai)電(dian)(dian)(dian)(dian)線(xian)(xian)(xian)(xian)(xian)；在(zai)(zai)一(yi)(yi)路線(xian)(xian)(xian)(xian)(xian)里中間(jian)不(bu)要(yao)接頭；電(dian)(dian)(dian)(dian)線(xian)(xian)(xian)(xian)(xian)接入電(dian)(dian)(dian)(dian)器箱(盒)時(shi)不(bu)要(yao)碰(peng)(peng)線(xian)(xian)(xian)(xian)(xian)；另外用(yong)(yong)電(dian)(dian)(dian)(dian)量較(jiao)大的家(jia)用(yong)(yong)電(dian)(dian)(dian)(dian)器如空調等(deng)應(ying)單(dan)獨一(yi)(yi)路電(dian)(dian)(dian)(dian)線(xian)(xian)(xian)(xian)(xian)供電(dian)(dian)(dian)(dian)；弱電(dian)(dian)(dian)(dian)、強電(dian)(dian)(dian)(dian)用(yong)(yong)的電(dian)(dian)(dian)(dian)線(xian)(xian)(xian)(xian)(xian)保持(chi)一(yi)(yi)定距(ju)離。

電纜(lan)線路常見(jian)的故障有(you)機械損傷、絕緣損傷、絕緣受潮、絕緣老化(hua)變質、過電壓、電纜(lan)過熱故障等。當線路發(fa)生上述故障時，應切斷故障電纜(lan)的電源，尋(xun)找(zhao)故障點，對故障進行(xing)檢查及分析(xi)，然后(hou)(hou)進行(xing)修(xiu)理和試驗，該割除的割除，待故障消除后(hou)(hou)，方可恢(hui)復供(gong)電。
