電線電纜行業簡介

一、常用電線電纜型號

電(dian)線電(dian)纜中 有BV、BLV、BVVB、BVR、RV、RVS、RVV、QVR、AVVR、VV、VLV、KVV等諸(zhu)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(yin)為大(da)品牌(pai)會更珍惜自身(shen)的品牌(pai)形象和品牌(pai)價值，不(bu)會做虛假宣傳的，而且更加注重品質(zhi)和服務。

三、電線安裝注意事項

在鋪設(she)電線的(de)過程(cheng)中應盡(jin)量避免出現(xian)接頭(tou)，要按照正確的(de)連線方式接線；還(huan)要選擇合(he)理的(de)安(an)裝(zhuang)形式，安(an)裝(zhuang)室內電線可(ke)選擇采用明(ming)裝(zhuang)和(he)暗裝(zhuang)兩種(zhong)不(bu)同的(de)形式；需要用三相插頭(tou)的(de)電器，一定要安(an)裝(zhuang)可(ke)靠的(de)地線。

四、電線顏色代表什么線

1、紅、黃(huang)、綠：代表火線，對地電壓為220V。

2、藍色：代表中性線(xian)即(ji)零線(xian)，跟大地相連，對地電壓為0，位置在水平排(pai)(pai)列(lie)靠(kao)近房屋一側或者垂直排(pai)(pai)列(lie)最下面(mian)一條。

3、黃綠雙色(se)線：代表保護中(zhong)性(xing)線即地線。

4、A相為黃(huang)色(se)，B相為綠色(se)，C相為紅(hong)色(se)：代表母(mu)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(zhi) 不同(tong)、鋪設(she)方式不同(tong)，所承(cheng)受的(de)電器(qi)功率大小都有所不同(tong)。

2.5平方(fang)的(de)(de)(de)銅芯線(xian)(xian)(xian)(xian)，明(ming)線(xian)(xian)(xian)(xian)鋪(pu)(pu)設(she)(she)時可(ke)承(cheng)受(shou)(shou)5500瓦(wa)(wa)以(yi)(yi)(yi)內的(de)(de)(de)電(dian)(dian)器(qi)(qi)功(gong)(gong)(gong)(gong)率；暗線(xian)(xian)(xian)(xian)鋪(pu)(pu)設(she)(she)可(ke)以(yi)(yi)(yi)承(cheng)受(shou)(shou)3500瓦(wa)(wa)以(yi)(yi)(yi)內的(de)(de)(de)電(dian)(dian)器(qi)(qi)功(gong)(gong)(gong)(gong)率；鋁芯線(xian)(xian)(xian)(xian)明(ming)線(xian)(xian)(xian)(xian)鋪(pu)(pu)設(she)(she)可(ke)以(yi)(yi)(yi)承(cheng)受(shou)(shou)4400瓦(wa)(wa)以(yi)(yi)(yi)內的(de)(de)(de)電(dian)(dian)器(qi)(qi)功(gong)(gong)(gong)(gong)率；暗線(xian)(xian)(xian)(xian)鋪(pu)(pu)設(she)(she)可(ke)以(yi)(yi)(yi)承(cheng)受(shou)(shou)2800瓦(wa)(wa)以(yi)(yi)(yi)內的(de)(de)(de)電(dian)(dian)器(qi)(qi)功(gong)(gong)(gong)(gong)率；4平方(fang)的(de)(de)(de)銅芯線(xian)(xian)(xian)(xian)，明(ming)線(xian)(xian)(xian)(xian)鋪(pu)(pu)設(she)(she)可(ke)以(yi)(yi)(yi)承(cheng)受(shou)(shou)7000瓦(wa)(wa)以(yi)(yi)(yi)內的(de)(de)(de)電(dian)(dian)器(qi)(qi)功(gong)(gong)(gong)(gong)率；暗線(xian)(xian)(xian)(xian)鋪(pu)(pu)設(she)(she)可(ke)以(yi)(yi)(yi)承(cheng)受(shou)(shou)5500瓦(wa)(wa)以(yi)(yi)(yi)內的(de)(de)(de)電(dian)(dian)器(qi)(qi)功(gong)(gong)(gong)(gong)率；鋁芯線(xian)(xian)(xian)(xian)明(ming)線(xian)(xian)(xian)(xian)鋪(pu)(pu)設(she)(she)時可(ke)承(cheng)受(shou)(shou)5500瓦(wa)(wa)以(yi)(yi)(yi)內的(de)(de)(de)電(dian)(dian)器(qi)(qi)功(gong)(gong)(gong)(gong)率；暗線(xian)(xian)(xian)(xian)可(ke)以(yi)(yi)(yi)承(cheng)受(shou)(shou)4400瓦(wa)(wa)以(yi)(yi)(yi)內的(de)(de)(de)電(dian)(dian)器(qi)(qi)功(gong)(gong)(gong)(gong)率。
