生活中(zhong)常用(yong)的(de)電(dian)(dian)(dian)線(xian)一(yi)般有1.5、2.5、4、6、10平方(fang)銅電(dian)(dian)(dian)線(xian)，2.5平方(fang)電(dian)(dian)(dian)線(xian)使(shi)用(yong)的(de)方(fang)面(mian)很多。下面(mian)給大家說一(yi)說2.5平方(fang)電(dian)(dian)(dian)線(xian)負荷，2.5平方(fang)電(dian)(dian)(dian)線(xian)價(jia)格，說不定你什么時候(hou)可以(yi)用(yong)得上。

一(yi)、2.5平方電(dian)線負(fu)荷(he)

一般情況50a以下1平方毫米安全載流量是(shi)(shi)6a，50-100a電流(liu)載電流(liu)量是(shi)(shi)5a，100a以(yi)上的(de)(de)話則取1平(ping)方毫米的(de)(de)安全(quan)載流(liu)量是(shi)(shi)2.5A;那么多大平(ping)方的(de)(de)銅電纜就(jiu)(jiu)能算(suan)(suan)出電流(liu)了(le)。按照三(san)相交流(liu)電公式如(ru)下P=1.732*U*I*cosφ，cosφ是(shi)(shi)功(gong)率因數(shu)，選(xuan)0.8;這(zhe)就(jiu)(jiu)是(shi)(shi)三(san)相功(gong)率計算(suan)(suan)公式。單相的(de)(de)：P=U*I*cosφ，cosφ是(shi)(shi)功(gong)率因數(shu)功(gong)率因數(shu)對于阻性(xing)負載是(shi)(shi)1，感(gan)性(xing)負載選(xuan)0.8。

二、2.5平方電線能帶多(duo)少瓦

國(guo)標GB4706.1-2005規定的(de)電線負載電流(liu)值：銅芯(xin)線截(jie)面積(ji)2.5 mm2允許長期電流(liu)16A~25A 。換算功率3500~5500W。具體使用(yong)(yong)因(yin)導(dao)線長度、連續使用(yong)(yong)時間長短以及使用(yong)(yong)方法(穿管、直埋等影響散(san)熱因(yin)素)等因(yin)素不同而區(qu)別選用(yong)(yong)。

三、2.5平方電(dian)線(xian)價(jia)格

現在一般使用單芯2.5平方的(de)銅導線用的(de)比較多。電線品牌不(bu)同價(jia)格也(ye)很不(bu)同，現在正常國標BV2.5的(de)電線價(jia)格在160元/米(mi)(mi)到170元/100米(mi)(mi)。好一些(xie)牌子的(de)有230元/米(mi)(mi)到240元/100米(mi)(mi)，也(ye)有便(bian)宜的(de)120元/100米(mi)(mi)，不(bu)過質量和數(shu)量都很差(cha)的(de)。

上面介紹了2.5平(ping)方(fang)電(dian)線(xian)負荷、2.5平(ping)方(fang)電(dian)線(xian)價(jia)格的(de)知識，也許在(zai)生活在(zai)用到的(de)時(shi)候不多，但(dan)是(shi)掌握了總是(shi)沒壞處(chu)。至少我們要清(qing)楚自己(ji)室內的(de)電(dian)線(xian)是(shi)幾(ji)平(ping)方(fang)的(de)，然后在(zai)使用家電(dian)時(shi)要合(he)理(li)安排。

2.5平方(fang)電線一(yi)般用于什(shen)么電器

電(dian)(dian)(dian)(dian)器(qi)(qi)(qi)有(you)空調(diao)、電(dian)(dian)(dian)(dian)熱水器(qi)(qi)(qi)、電(dian)(dian)(dian)(dian)飯鍋、冰箱(xiang)、電(dian)(dian)(dian)(dian)磁(ci)爐(lu)、紅(hong)外取暖(nuan)器(qi)(qi)(qi)等，生活中(zhong)都要用到，2.5平(ping)方毫米(mi)的(de)銅(tong)導(dao)線(xian)(xian)能帶(dai)動(dong)多(duo)少電(dian)(dian)(dian)(dian)器(qi)(qi)(qi)呢?如果按2.5平(ping)方毫米(mi)的(de)銅(tong)導(dao)線(xian)(xian)計(ji)算，可(ke)以(yi)通(tong)過的(de)安全電(dian)(dian)(dian)(dian)流(liu)是(shi)(shi)2.5*8=20A。如1.5匹空調(diao)的(de)啟動(dong)最(zui)大(da)電(dian)(dian)(dian)(dian)流(liu)10A，普通(tong)電(dian)(dian)(dian)(dian)熱水器(qi)(qi)(qi)工(gong)(gong)作電(dian)(dian)(dian)(dian)流(liu)在5A左(zuo)(zuo)右，電(dian)(dian)(dian)(dian)飯鍋工(gong)(gong)作電(dian)(dian)(dian)(dian)流(liu)在5A以(yi)下(xia)，電(dian)(dian)(dian)(dian)磁(ci)爐(lu)的(de)工(gong)(gong)作電(dian)(dian)(dian)(dian)流(liu)在10A左(zuo)(zuo)右，紅(hong)外取暖(nuan)器(qi)(qi)(qi)電(dian)(dian)(dian)(dian)流(liu)在6A左(zuo)(zuo)右，這些(xie)都是(shi)(shi)大(da)功(gong)率(lv)(lv)電(dian)(dian)(dian)(dian)器(qi)(qi)(qi)了。這些(xie)大(da)功(gong)率(lv)(lv)電(dian)(dian)(dian)(dian)器(qi)(qi)(qi)同(tong)(tong)時工(gong)(gong)作不(bu)要超(chao)過三個，如果同(tong)(tong)時工(gong)(gong)作兩(liang)個的(de)話還是(shi)(shi)可(ke)以(yi)的(de)。如果家里沒有(you)開空調(diao)，那(nei)么(me)同(tong)(tong)時有(you)三個電(dian)(dian)(dian)(dian)器(qi)(qi)(qi)工(gong)(gong)作，還是(shi)(shi)可(ke)以(yi)的(de)。特別注意，空調(diao)和電(dian)(dian)(dian)(dian)磁(ci)爐(lu)是(shi)(shi)功(gong)率(lv)(lv)最(zui)大(da)的(de)電(dian)(dian)(dian)(dian)器(qi)(qi)(qi)，這兩(liang)個大(da)功(gong)率(lv)(lv)電(dian)(dian)(dian)(dian)器(qi)(qi)(qi)，盡量(liang)不(bu)要同(tong)(tong)時工(gong)(gong)作。如果用快速(su)電(dian)(dian)(dian)(dian)熱水器(qi)(qi)(qi)，那(nei)么(me)需要單獨布線(xian)(xian)，快速(su)電(dian)(dian)(dian)(dian)熱水器(qi)(qi)(qi)的(de)功(gong)率(lv)(lv)達到3000W，因此需要4平(ping)方的(de)銅(tong)導(dao)線(xian)(xian)單獨供電(dian)(dian)(dian)(dian)，這種電(dian)(dian)(dian)(dian)器(qi)(qi)(qi)對(dui)導(dao)線(xian)(xian)的(de)要求太高(gao)了。
