家装各回路用2.5还是4平方电线,记住这两句口诀,轻松选配电线,装修大忌!全屋装4平方线,烧钱又毁房!附:家庭用电线计算公式,电线大小的应用,家fang yuan dian xian cu le bing bu dai biao fei dian , qi shi zhe ge gen yong dian dian qi de gong lv hai shi you hen da de guan xi de , dian xian heng jie mian ji da yi ban shi ke yi shi yong yu gong lv bi jiao da de dian qi , er gong lv bi jiao da de dian qi zai shi yong de shi hou hao de dian liang hui geng jia duo yi xie 。dan shi ye you de dian qi ben shen hai shi bi jiao jie neng de "

4平方电线和6平方电线严格来说是6平方电线费电,因为它截面积大,体电阻率可就会大,所以在相同电流的情况下,自身发热会大。由于是使用纯铜造的电线,电阻率是非常小的,家庭中不论使用4平方还是6平方电线,其方圆电线粗了并不代表费电,其实这个跟用电电器的功率还是有很大的关系的,电线横截面积大一般是可以适用于功率比较大的电器,而功率比较大的电器在使用的时候好的电量会更加多一些。但是也有的电器本身还是比较节能的
厨房间的电线用大一点好且安全,6平方比4平方的内阻小,理论上是电是的平方大了,就是费电的。qingqing829 关键是看安全性。有的误解是房屋的面积平方米其实楼主的意思估计是电线的截面积平方毫米呵呵,各个平方的电4 ping fang dian xian he 6 ping fang dian xian yan ge lai shuo shi 6 ping fang dian xian fei dian , yin wei ta jie mian ji da , ti dian zu lv ke jiu hui da , suo yi zai xiang tong dian liu de qing kuang xia , zi shen fa re hui da 。you yu shi shi yong chun tong zhi zao de dian xian , dian zu lv shi fei chang xiao de , jia ting zhong bu lun shi yong 4 ping fang hai shi 6 ping fang dian xian , qi "
