電線電纜行業簡介

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(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。因為大品牌(pai)會更(geng)珍惜自身的品牌(pai)形象和品牌(pai)價值(zhi)，不會做虛假宣傳(chuan)的，而且更(geng)加注(zhu)重品質和服務。

三、電線安裝注意事項

在鋪設(she)電(dian)線(xian)的過(guo)程(cheng)中應盡(jin)量避免出(chu)現接頭，要按照(zhao)正確的連線(xian)方式接線(xian)；還要選擇(ze)合(he)理的安裝形(xing)式，安裝室內電(dian)線(xian)可(ke)選擇(ze)采用明裝和暗(an)裝兩種不同的形(xing)式；需要用三相(xiang)插(cha)頭的電(dian)器，一定要安裝可(ke)靠的地線(xian)。

四、電線顏色代表什么線

1、紅(hong)、黃、綠(lv)：代(dai)表火線，對地電壓為220V。

2、藍(lan)色(se)：代表中性線(xian)即零線(xian)，跟(gen)大地(di)相連，對地(di)電壓為0，位置在水平排列(lie)靠(kao)近房屋(wu)一(yi)側(ce)或者垂直排列(lie)最下面(mian)一(yi)條。

3、黃綠雙(shuang)色線：代表(biao)保護中性線即地線。

4、A相為(wei)黃色，B相為(wei)綠(lv)色，C相為(wei)紅色：代表母線。

五、家用電線能承受多大功率

電源(yuan)線的規格不(bu)(bu)同、材質 不(bu)(bu)同、鋪(pu)設方式不(bu)(bu)同，所(suo)(suo)承(cheng)受的電器功率大小都有所(suo)(suo)不(bu)(bu)同。
