美标线与国标线对照表,线径规格对照表

中美线规线径对照表(简版请点击访问)注释： AWG(Americanwiregauge )是美国制电线标准的简称。 在发音习惯上，把Gauge的发音[geidg]作为AWG的简写短语整体的发音。 区分美国导线直径的标准也称为BS线程，即Brown Sharps线程。 铜线的直径通常以AWG (美国导线标准)为单位进行测量。 AWG值是导线线径(以英寸为单位)的函数。 AWG之前的数值(例如24AWG、26AWG )表示引线在最小直径之前通过的孔的数量，数值越大，引线通过的孔越多，引线的直径也越小。 粗导线具有更好的物理强度和更低的电阻，但导线越粗，制作电缆所需的铜越多，这次电缆变重，安装难度大，价格也越高。 电缆设计的课题是在以必要的电压和频率确保导线的最大容量的同时，尽量使用小径的导线。
