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等諸多型(xing)號(hao)。

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)(pai)會(hui)更珍(zhen)惜自身的品(pin)牌(pai)(pai)形象和品(pin)牌(pai)(pai)價值，不會(hui)做(zuo)虛(xu)假宣傳(chuan)的，而且更加注重(zhong)品(pin)質和服務(wu)。

三、電線安裝注意事項

在鋪設電(dian)線(xian)(xian)的(de)過程中應盡量(liang)避免出現接頭(tou)，要按照正確的(de)連線(xian)(xian)方式(shi)接線(xian)(xian)；還要選(xuan)擇合理(li)的(de)安裝(zhuang)形(xing)式(shi)，安裝(zhuang)室內電(dian)線(xian)(xian)可(ke)選(xuan)擇采用(yong)明裝(zhuang)和暗裝(zhuang)兩種不同(tong)的(de)形(xing)式(shi)；需要用(yong)三(san)相插頭(tou)的(de)電(dian)器，一定要安裝(zhuang)可(ke)靠的(de)地線(xian)(xian)。

四、電線顏色代表什么線

1、紅、黃(huang)、綠：代表(biao)火線(xian)，對地(di)電壓為220V。

2、藍色：代表中性線即(ji)零線，跟大地(di)(di)相連(lian)，對地(di)(di)電壓為0，位置(zhi)在水平(ping)排(pai)(pai)列靠近房屋一側或者垂(chui)直排(pai)(pai)列最下(xia)面一條。

3、黃(huang)綠雙色線(xian)：代表保(bao)護中(zhong)性線(xian)即(ji)地線(xian)。

4、A相為(wei)黃色，B相為(wei)綠色，C相為(wei)紅色：代(dai)表母線。

五、家用電線能承受多大功率

電源線的規格不(bu)同(tong)(tong)、材質 不(bu)同(tong)(tong)、鋪設方式不(bu)同(tong)(tong)，所(suo)承受(shou)的電器功率(lv)大小都(dou)有所(suo)不(bu)同(tong)(tong)。
