AWG计算方法

AWG含义

American Wire Guide

计算方法

AWG#=49.8813-9.92980logA

说明

A-导体面积(园密尔)

A=d1*d1+d2*d2+........+dn*dn

dn-绞合单丝直径(密尔)

举例

求7/0.16mm 线规数(AWG)

1:0.16mm=6.2992mil

2:A=7X6.2992X6.2992=277.759

3:AWG#=25.62(约=26)

3楼的看得不是很清楚,我想知道0.16mm=6.2992mil是怎么得来的 AWG#=49.8813-9.92980logA 中的log代表的是什么?
