各位:我在數(shù)字通信中用的雙絞線,在這里請為線規(guī)是什么?如獲至寶 20 AWG  ,22AWG,   23 AWG.......

          那個標準上有?

         如果有表示什么?

AWG計算方法

AWG含義

American Wire Guide

計算方法

AWG#＝49.8813-9.92980logA

說明

A-導體面積（園密爾）

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

dn-絞合單絲直徑（密爾）

舉例

求7/0.16mm 線規(guī)數(shù)（AWG)

1：0.16mm=6.2992mil

2：A=7X6.2992X6.2992=277.759

3：AWG#=25.62（約＝26）
