電線電纜廠家的注意事項

常見的電纜故(gu)障

電(dian)(dian)線(xian)表面標(biao)志——根(gen)據(ju)國家標(biao)準規定(ding)，電(dian)(dian)線(xian)表面應(ying)(ying)有制造(zao)廠名(ming)、產品(pin)型號(hao)和額(e)定(ding)電(dian)(dian)壓的連續標(biao)志。這有利于在(zai)電(dian)(dian)線(xian)使用過(guo)程(cheng)中發生(sheng)問題時能及(ji)時找到(dao)制造(zao)廠，消(xiao)費者(zhe)在(zai)選購電(dian)(dian)線(xian)時務(wu)必注意這一(yi)點。同時消(xiao)費者(zhe)在(zai)選購電(dian)(dian)線(xian)時應(ying)(ying)注意合格(ge)證上標(biao)明的制造(zao)廠名(ming)、產品(pin)型號(hao)、額(e)定(ding)電(dian)(dian)壓與電(dian)(dian)線(xian)表面的印刷標(biao)志是否(fou)一(yi)致(zhi)，防止冒牌產品(pin)。 　　

電(dian)(dian)線(xian)(xian)外觀——消費者在選購電(dian)(dian)線(xian)(xian)時(shi)(shi)應(ying)注意電(dian)(dian)線(xian)(xian)的(de)外觀應(ying)光滑平整(zheng)，絕緣和護套(tao)層(ceng)無損壞(huai)，標志印字清(qing)晰(xi)，手(shou)模電(dian)(dian)線(xian)(xian)時(shi)(shi)無油膩感。從(cong)電(dian)(dian)線(xian)(xian)的(de)橫截面看，電(dian)(dian)線(xian)(xian)的(de)整(zheng)個圓周上絕緣或護套(tao)的(de)厚(hou)度(du)(du)應(ying)均勻，不應(ying)偏芯，絕緣或護套(tao)應(ying)有一定的(de)厚(hou)度(du)(du)。 　　

導(dao)體(ti)線(xian)(xian)徑——消費者在選(xuan)購電(dian)線(xian)(xian)時(shi)應注(zhu)意導(dao)體(ti)線(xian)(xian)徑是否與合(he)格(ge)證上(shang)(shang)明示(shi)的截面(mian)相符(fu)，若(ruo)導(dao)體(ti)截面(mian)偏小，容(rong)易使(shi)電(dian)線(xian)(xian)發熱引起短(duan)路。建(jian)議家庭照明線(xian)(xian)路用(yong)電(dian)線(xian)(xian)采用(yong)1.5平方毫米及以(yi)上(shang)(shang)規格(ge)；空調、微波爐等用(yong)功率(lv)較大的家用(yong)電(dian)器應采用(yong)2.5平方毫米及以(yi)上(shang)(shang)規格(ge)的電(dian)線(xian)(xian)。 　　

規范(fan)使用(yong)(yong)——應(ying)規范(fan)布(bu)線(xian)(xian)(xian)(xian)(xian)，固定線(xian)(xian)(xian)(xian)(xian)路最好(hao)采用(yong)(yong)BV單(dan)(dan)芯(xin)線(xian)(xian)(xian)(xian)(xian)穿管(guan)子，注(zhu)意在布(bu)線(xian)(xian)(xian)(xian)(xian)時不(bu)要(yao)(yao)碰(peng)壞電(dian)(dian)(dian)線(xian)(xian)(xian)(xian)(xian),在房間裝潢時不(bu)要(yao)(yao)碰(peng)壞電(dian)(dian)(dian)線(xian)(xian)(xian)(xian)(xian)；在一路線(xian)(xian)(xian)(xian)(xian)里中間不(bu)要(yao)(yao)接頭(tou)；電(dian)(dian)(dian)線(xian)(xian)(xian)(xian)(xian)接入電(dian)(dian)(dian)器箱(xiang)(盒)時不(bu)要(yao)(yao)碰(peng)線(xian)(xian)(xian)(xian)(xian)；另(ling)外用(yong)(yong)電(dian)(dian)(dian)量較大的(de)家用(yong)(yong)電(dian)(dian)(dian)器如空調等應(ying)單(dan)(dan)獨一路電(dian)(dian)(dian)線(xian)(xian)(xian)(xian)(xian)供電(dian)(dian)(dian)；弱電(dian)(dian)(dian)、強(qiang)電(dian)(dian)(dian)用(yong)(yong)的(de)電(dian)(dian)(dian)線(xian)(xian)(xian)(xian)(xian)最好(hao)保持(chi)一定距離。 　　

電(dian)(dian)(dian)纜線(xian)路常見的故(gu)(gu)障(zhang)有機械(xie)損傷、絕(jue)緣損傷、絕(jue)緣受(shou)潮、絕(jue)緣老化變質、過(guo)(guo)電(dian)(dian)(dian)壓、電(dian)(dian)(dian)纜過(guo)(guo)熱故(gu)(gu)障(zhang)等。當線(xian)路發生(sheng)上述故(gu)(gu)障(zhang)時(shi)，應切斷故(gu)(gu)障(zhang)電(dian)(dian)(dian)纜的電(dian)(dian)(dian)源，尋(xun)找故(gu)(gu)障(zhang)點，對故(gu)(gu)障(zhang)進(jin)行(xing)檢(jian)查(cha)及分析(xi)，然后進(jin)行(xing)修理和試(shi)驗，該割除(chu)的割除(chu)，待故(gu)(gu)障(zhang)消除(chu)后，方(fang)可恢(hui)復供電(dian)(dian)(dian)。

埋設電(dian)纜的安全(quan)要(yao)求

1、電纜線相互交叉時(shi)，高(gao)壓(ya)電纜應在低壓(ya)電纜下方。如果其中一條電纜在交叉點(dian)前后1m范圍內(nei)穿管保護或用隔(ge)板隔(ge)開時(shi)，最小(xiao)允許距離(li)為0.15m。 　　

2、電纜與(yu)熱力(li)管(guan)道(dao)接近(jin)或交叉時(shi)，如有隔熱措施(shi)，平行(xing)和交叉的最小距離分別為0.5m和0.15m。 　　

3、電纜與(yu)鐵(tie)路(lu)或道(dao)路(lu)交叉時應(ying)穿管保護(hu)，保護(hu)管應(ying)伸出軌道(dao)或路(lu)面2m以(yi)外。 　　

4、電(dian)纜(lan)(lan)與建(jian)(jian)筑(zhu)(zhu)物(wu)基礎的距離，應(ying)能保證(zheng)電(dian)纜(lan)(lan)埋(mai)設(she)在建(jian)(jian)筑(zhu)(zhu)物(wu)散水以外(wai)；電(dian)纜(lan)(lan)引(yin)入建(jian)(jian)筑(zhu)(zhu)物(wu)時應(ying)穿管(guan)保護，保護管(guan)亦應(ying)超出建(jian)(jian)筑(zhu)(zhu)物(wu)散水以外(wai)。 　　

5、直(zhi)(zhi)接埋(mai)在(zai)地(di)下(xia)的(de)電纜與(yu)一(yi)般接地(di)裝置的(de)接地(di)之間應(ying)相距(ju)0.15~0.5m；直(zhi)(zhi)接埋(mai)在(zai)地(di)下(xia)的(de)電纜埋(mai)設深度，一(yi)般不(bu)應(ying)小于(yu)0.7m，并應(ying)埋(mai)在(zai)凍(dong)土層下(xia)。
