4平方電源線能負(fù)載多少千瓦

今天去會(huì)見一個(gè)客戶,談到4平方線能負(fù)載多少臺(tái)電腦的問題?

我說4平方線(金龍羽)能負(fù)載5千瓦,但在現(xiàn)場(chǎng)的一個(gè)師傅說,只能負(fù)載4千瓦。據(jù)我平時(shí)計(jì)算,一般的一組4平方線20臺(tái)電腦是沒有問題的,一般電腦是250W,20臺(tái)也是5000瓦,實(shí)際沒有那么多。我在金龍羽網(wǎng)站查到4平方線負(fù)載電流是44安,220V(電壓)*44A(電流)=9680瓦,這是理論算法,實(shí)際上我一般不超過20臺(tái),我也一直這樣做,都沒有什么異常情況發(fā)生。但有的電工說4平方線只能帶10臺(tái)電腦,我不知他是根據(jù)什么來計(jì)算的。
