各位大俠,請教一下電源線的電流與其截面積的關系是否有公式可以算的,具體的公式是??

根據(jù)UL62的條文，我們可以大概的得出電流和線規(guī)大小的對應，沒有具體公式

見UL62 2000版的32.1和32.1（新版UL62 2006里面沒有了這部分內容）

謝謝回復,你是否有這方面的資料,共亨一下或發(fā)給我郵箱:heqy_1982@163.com在此先謝了..

電源線用于插頭, 18AWG對應10A, 16AWG對應13A, 14AWG對應15A, 其他我就不知道了.

這個問題問得好, 困擾我很久了.

與外被，導體數(shù)，電纜長度都有關係

SJ、SJO        18AWG   2導體        0-15.2m 10A   超過7A

                                         3導體        0-15.2m  7A   超過5.6A

我也想要這方面的資料,如果哪位朋友有的,希望你能發(fā)一份EM給我,我的EM是:1133.52@163.com,謝謝

我也想知道，20,22,24,26和28AWG分別對應多少A電流？
