一、常用電線電纜型號
電線電纜中 有BV、BLV、BVVB、BVR、RV、RVS、RVV、QVR、AVVR、VV、VLV、KVV等諸多型號。
二、電線電纜如何挑選
首先看包裝是否有合格證、中國國家強制產品認證的“CCC”和出產許可證號;其次要檢查電線尺寸誤差;然后看銅芯顏色、絕緣膠皮、電線重量、電線芯大小等;最后選購的時候,最好選擇信譽良好的電線電纜品牌產品。因為大品牌(pai)會更珍惜自身的品牌(pai)形象(xiang)和(he)(he)品牌(pai)價(jia)值,不會做虛假宣傳的,而且更加注重品質和(he)(he)服(fu)務。
三、電線安裝注意事項
在(zai)鋪設電線(xian)(xian)的(de)(de)過程中應盡量避免(mian)出現接頭,要按(an)照正確的(de)(de)連線(xian)(xian)方(fang)式(shi)接線(xian)(xian);還要選擇合(he)理的(de)(de)安裝形式(shi),安裝室內電線(xian)(xian)可選擇采用(yong)明裝和暗裝兩種不同(tong)的(de)(de)形式(shi);需要用(yong)三相插(cha)頭的(de)(de)電器,一(yi)定要安裝可靠的(de)(de)地線(xian)(xian)。
四、電線顏色代表什么線
1、紅、黃、綠:代表火線(xian),對地電壓為220V。
2、藍(lan)色:代表中性線(xian)即零線(xian),跟大地(di)相連,對地(di)電壓(ya)為0,位(wei)置在(zai)水平排(pai)列靠近(jin)房屋一側或(huo)者垂直排(pai)列最下面一條。
3、黃綠雙(shuang)色線(xian):代表保護(hu)中性線(xian)即地線(xian)。
4、A相為(wei)黃(huang)色(se)(se),B相為(wei)綠色(se)(se),C相為(wei)紅(hong)色(se)(se):代表母(mu)線。
五、家用電線能承受多大功率
電(dian)源線的規格(ge)不(bu)(bu)同(tong)(tong)、材質 不(bu)(bu)同(tong)(tong)、鋪設方式(shi)不(bu)(bu)同(tong)(tong),所(suo)承(cheng)受的電(dian)器(qi)功率大小都(dou)有所(suo)不(bu)(bu)同(tong)(tong)。
2.5平方的(de)銅芯(xin)線(xian),明(ming)線(xian)鋪(pu)(pu)(pu)設時可承(cheng)(cheng)受(shou)(shou)5500瓦(wa)(wa)以(yi)(yi)(yi)內(nei)(nei)的(de)電(dian)(dian)(dian)器(qi)(qi)(qi)功(gong)(gong)率(lv)(lv);暗線(xian)鋪(pu)(pu)(pu)設可以(yi)(yi)(yi)承(cheng)(cheng)受(shou)(shou)3500瓦(wa)(wa)以(yi)(yi)(yi)內(nei)(nei)的(de)電(dian)(dian)(dian)器(qi)(qi)(qi)功(gong)(gong)率(lv)(lv);鋁芯(xin)線(xian)明(ming)線(xian)鋪(pu)(pu)(pu)設可以(yi)(yi)(yi)承(cheng)(cheng)受(shou)(shou)4400瓦(wa)(wa)以(yi)(yi)(yi)內(nei)(nei)的(de)電(dian)(dian)(dian)器(qi)(qi)(qi)功(gong)(gong)率(lv)(lv);暗線(xian)鋪(pu)(pu)(pu)設可以(yi)(yi)(yi)承(cheng)(cheng)受(shou)(shou)2800瓦(wa)(wa)以(yi)(yi)(yi)內(nei)(nei)的(de)電(dian)(dian)(dian)器(qi)(qi)(qi)功(gong)(gong)率(lv)(lv);4平方的(de)銅芯(xin)線(xian),明(ming)線(xian)鋪(pu)(pu)(pu)設可以(yi)(yi)(yi)承(cheng)(cheng)受(shou)(shou)7000瓦(wa)(wa)以(yi)(yi)(yi)內(nei)(nei)的(de)電(dian)(dian)(dian)器(qi)(qi)(qi)功(gong)(gong)率(lv)(lv);暗線(xian)鋪(pu)(pu)(pu)設可以(yi)(yi)(yi)承(cheng)(cheng)受(shou)(shou)5500瓦(wa)(wa)以(yi)(yi)(yi)內(nei)(nei)的(de)電(dian)(dian)(dian)器(qi)(qi)(qi)功(gong)(gong)率(lv)(lv);鋁芯(xin)線(xian)明(ming)線(xian)鋪(pu)(pu)(pu)設時可承(cheng)(cheng)受(shou)(shou)5500瓦(wa)(wa)以(yi)(yi)(yi)內(nei)(nei)的(de)電(dian)(dian)(dian)器(qi)(qi)(qi)功(gong)(gong)率(lv)(lv);暗線(xian)可以(yi)(yi)(yi)承(cheng)(cheng)受(shou)(shou)4400瓦(wa)(wa)以(yi)(yi)(yi)內(nei)(nei)的(de)電(dian)(dian)(dian)器(qi)(qi)(qi)功(gong)(gong)率(lv)(lv)。
