1、精品好文档，推荐学习交流AWG是AmericanWireGauge的简称，单线导体是根据直径、绞线是根据横截面积来决定线号。 CANARE公司使用的导体线号如下表所示。另外，线号越大说明导体的横截面积越小。AWG              导体横截面积(mm2) 13                         2.81 14                         2.18 15                         1.75 16                         1.27 18                         1.00

5、的函数。下表是AWG与公制、英制单位的对照表。其中，4/0表示0000，3/0表示000，2/0表示00，1/0表示0。例如，常用的电话线直径为26AWG，约为0.4mm。 AWG外径截面积(mm2)电阻值(W/km)AWG外径截面积(mm2)电阻值(W/km) 公制mm英制inch公制mm英制inch 4/011.680.46107.220.17220.6430.02530.324754.3 3/010.400.409685.010.21230.5740.02260.258848.5 2/09.270.364867.430.26240.5110.02010.204789.4
