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(pin)。因為大品(pin)牌(pai)會(hui)更珍惜自身的(de)品(pin)牌(pai)形(xing)象(xiang)和品(pin)牌(pai)價值(zhi)，不會(hui)做虛(xu)假宣(xuan)傳的(de)，而且更加(jia)注重品(pin)質(zhi)和服務。

三、電線安裝注意事項

在鋪設(she)電線(xian)的(de)過程中(zhong)應(ying)盡量避(bi)免出現接頭，要按照正(zheng)確的(de)連線(xian)方式(shi)接線(xian)；還要選擇合理的(de)安(an)裝形(xing)式(shi)，安(an)裝室內(nei)電線(xian)可(ke)選擇采(cai)用(yong)明裝和暗裝兩種不(bu)同的(de)形(xing)式(shi)；需(xu)要用(yong)三相插頭的(de)電器，一定要安(an)裝可(ke)靠的(de)地線(xian)。

四、電線顏色代表什么線

1、紅(hong)、黃、綠：代表火線(xian)，對地電(dian)壓為220V。

2、藍色：代表中性線即零(ling)線，跟大地相連(lian)，對地電壓為0，位(wei)置(zhi)在水平(ping)排列靠近房(fang)屋一(yi)側(ce)或者垂(chui)直排列最下面(mian)一(yi)條。

3、黃(huang)綠雙色(se)線：代(dai)表(biao)保護中性(xing)線即地線。

4、A相(xiang)為黃色(se)，B相(xiang)為綠(lv)色(se)，C相(xiang)為紅(hong)色(se)：代(dai)表母線。

五、家用電線能承受多大功率

電(dian)(dian)源線(xian)的規(gui)格不(bu)(bu)同(tong)、材(cai)質(zhi) 不(bu)(bu)同(tong)、鋪設方式不(bu)(bu)同(tong)，所(suo)(suo)承受的電(dian)(dian)器(qi)功率大小都有所(suo)(suo)不(bu)(bu)同(tong)。
