電線電纜行業簡介

一、常用電線電纜型號

電線電纜(lan)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。因為大品牌會更珍惜(xi)自身的品牌形象和(he)品牌價值(zhi)，不會做(zuo)虛假宣傳的，而(er)且(qie)更加(jia)注重品質和(he)服務。

三、電線安裝注意事項

在鋪設電(dian)線(xian)(xian)(xian)的(de)過(guo)程(cheng)中應盡(jin)量避免出(chu)現接頭，要按照正(zheng)確(que)的(de)連(lian)線(xian)(xian)(xian)方式(shi)(shi)接線(xian)(xian)(xian)；還要選擇合理的(de)安(an)裝(zhuang)形(xing)(xing)式(shi)(shi)，安(an)裝(zhuang)室內(nei)電(dian)線(xian)(xian)(xian)可選擇采(cai)用明(ming)裝(zhuang)和(he)暗裝(zhuang)兩(liang)種不(bu)同的(de)形(xing)(xing)式(shi)(shi)；需要用三(san)相插頭的(de)電(dian)器，一定要安(an)裝(zhuang)可靠的(de)地線(xian)(xian)(xian)。

四、電線顏色代表什么線

1、紅、黃、綠：代表火(huo)線，對(dui)地電壓為220V。

2、藍色：代表中(zhong)性線即零線，跟大(da)地相(xiang)連，對(dui)地電(dian)壓為0，位置(zhi)在水平排(pai)列靠近房屋一側或者垂直排(pai)列最下面一條。

3、黃綠雙(shuang)色(se)線：代表保護中性(xing)線即(ji)地線。

4、A相(xiang)為黃色(se)，B相(xiang)為綠色(se)，C相(xiang)為紅色(se)：代表母線(xian)。

五、家用電線能承受多大功率

電(dian)源線的(de)規格不同(tong)、材質 不同(tong)、鋪設方式不同(tong)，所(suo)承受的(de)電(dian)器功率大小都(dou)有(you)所(suo)不同(tong)。

2.5平方的(de)銅芯(xin)線(xian)(xian)，明(ming)線(xian)(xian)鋪(pu)(pu)設(she)時(shi)可(ke)(ke)承(cheng)(cheng)(cheng)受(shou)(shou)(shou)(shou)(shou)5500瓦(wa)以(yi)(yi)內(nei)的(de)電(dian)(dian)(dian)器功(gong)率(lv)(lv)(lv)；暗線(xian)(xian)鋪(pu)(pu)設(she)可(ke)(ke)以(yi)(yi)承(cheng)(cheng)(cheng)受(shou)(shou)(shou)(shou)(shou)3500瓦(wa)以(yi)(yi)內(nei)的(de)電(dian)(dian)(dian)器功(gong)率(lv)(lv)(lv)；鋁芯(xin)線(xian)(xian)明(ming)線(xian)(xian)鋪(pu)(pu)設(she)可(ke)(ke)以(yi)(yi)承(cheng)(cheng)(cheng)受(shou)(shou)(shou)(shou)(shou)4400瓦(wa)以(yi)(yi)內(nei)的(de)電(dian)(dian)(dian)器功(gong)率(lv)(lv)(lv)；暗線(xian)(xian)鋪(pu)(pu)設(she)可(ke)(ke)以(yi)(yi)承(cheng)(cheng)(cheng)受(shou)(shou)(shou)(shou)(shou)2800瓦(wa)以(yi)(yi)內(nei)的(de)電(dian)(dian)(dian)器功(gong)率(lv)(lv)(lv)；4平方的(de)銅芯(xin)線(xian)(xian)，明(ming)線(xian)(xian)鋪(pu)(pu)設(she)可(ke)(ke)以(yi)(yi)承(cheng)(cheng)(cheng)受(shou)(shou)(shou)(shou)(shou)7000瓦(wa)以(yi)(yi)內(nei)的(de)電(dian)(dian)(dian)器功(gong)率(lv)(lv)(lv)；暗線(xian)(xian)鋪(pu)(pu)設(she)可(ke)(ke)以(yi)(yi)承(cheng)(cheng)(cheng)受(shou)(shou)(shou)(shou)(shou)5500瓦(wa)以(yi)(yi)內(nei)的(de)電(dian)(dian)(dian)器功(gong)率(lv)(lv)(lv)；鋁芯(xin)線(xian)(xian)明(ming)線(xian)(xian)鋪(pu)(pu)設(she)時(shi)可(ke)(ke)承(cheng)(cheng)(cheng)受(shou)(shou)(shou)(shou)(shou)5500瓦(wa)以(yi)(yi)內(nei)的(de)電(dian)(dian)(dian)器功(gong)率(lv)(lv)(lv)；暗線(xian)(xian)可(ke)(ke)以(yi)(yi)承(cheng)(cheng)(cheng)受(shou)(shou)(shou)(shou)(shou)4400瓦(wa)以(yi)(yi)內(nei)的(de)電(dian)(dian)(dian)器功(gong)率(lv)(lv)(lv)。
