一、常用電線電纜型號
電線電纜(lan)中(zhong) 有BV、BLV、BVVB、BVR、RV、RVS、RVV、QVR、AVVR、VV、VLV、KVV等諸多(duo)型(xing)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(da)品牌會(hui)更(geng)珍惜自身的品牌形象和品牌價值(zhi),不(bu)會(hui)做虛(xu)假宣傳的,而且更(geng)加(jia)注重品質和服務。
三、電線安裝注意事項
在鋪設電(dian)線(xian)(xian)的(de)(de)過程中(zhong)應盡量避免出現接(jie)頭,要(yao)按照正確的(de)(de)連線(xian)(xian)方(fang)式(shi)接(jie)線(xian)(xian);還要(yao)選擇(ze)合(he)理的(de)(de)安裝(zhuang)形式(shi),安裝(zhuang)室(shi)內(nei)電(dian)線(xian)(xian)可選擇(ze)采用明(ming)裝(zhuang)和暗裝(zhuang)兩種(zhong)不同的(de)(de)形式(shi);需要(yao)用三相(xiang)插頭的(de)(de)電(dian)器,一(yi)定要(yao)安裝(zhuang)可靠的(de)(de)地線(xian)(xian)。
四、電線顏色代表什么線
1、紅、黃、綠:代(dai)表火線,對地電壓為220V。
2、藍色:代表中性(xing)線即零線,跟大地(di)相連,對地(di)電壓為0,位置在水平排列靠近房(fang)屋(wu)一側或者垂直(zhi)排列最下面一條。
3、黃綠(lv)雙(shuang)色線:代(dai)表保(bao)護(hu)中性線即(ji)地線。
4、A相為黃色(se),B相為綠色(se),C相為紅色(se):代表母線。
五、家用電線能承受多大功率
電源線的(de)規格不同(tong)、材質 不同(tong)、鋪設方式不同(tong),所(suo)(suo)承受(shou)的(de)電器功率(lv)大小都有(you)所(suo)(suo)不同(tong)。
2.5平方的(de)(de)銅(tong)芯(xin)(xin)線(xian)(xian)(xian)(xian),明(ming)線(xian)(xian)(xian)(xian)鋪(pu)設時可(ke)承受(shou)5500瓦(wa)以內(nei)的(de)(de)電器(qi)(qi)(qi)功(gong)(gong)(gong)率(lv);暗(an)線(xian)(xian)(xian)(xian)鋪(pu)設可(ke)以承受(shou)3500瓦(wa)以內(nei)的(de)(de)電器(qi)(qi)(qi)功(gong)(gong)(gong)率(lv);鋁芯(xin)(xin)線(xian)(xian)(xian)(xian)明(ming)線(xian)(xian)(xian)(xian)鋪(pu)設可(ke)以承受(shou)4400瓦(wa)以內(nei)的(de)(de)電器(qi)(qi)(qi)功(gong)(gong)(gong)率(lv);暗(an)線(xian)(xian)(xian)(xian)鋪(pu)設可(ke)以承受(shou)2800瓦(wa)以內(nei)的(de)(de)電器(qi)(qi)(qi)功(gong)(gong)(gong)率(lv);4平方的(de)(de)銅(tong)芯(xin)(xin)線(xian)(xian)(xian)(xian),明(ming)線(xian)(xian)(xian)(xian)鋪(pu)設可(ke)以承受(shou)7000瓦(wa)以內(nei)的(de)(de)電器(qi)(qi)(qi)功(gong)(gong)(gong)率(lv);暗(an)線(xian)(xian)(xian)(xian)鋪(pu)設可(ke)以承受(shou)5500瓦(wa)以內(nei)的(de)(de)電器(qi)(qi)(qi)功(gong)(gong)(gong)率(lv);鋁芯(xin)(xin)線(xian)(xian)(xian)(xian)明(ming)線(xian)(xian)(xian)(xian)鋪(pu)設時可(ke)承受(shou)5500瓦(wa)以內(nei)的(de)(de)電器(qi)(qi)(qi)功(gong)(gong)(gong)率(lv);暗(an)線(xian)(xian)(xian)(xian)可(ke)以承受(shou)4400瓦(wa)以內(nei)的(de)(de)電器(qi)(qi)(qi)功(gong)(gong)(gong)率(lv)。
