AWG_标准线径对照表

1、AWG标准线径对照表线径的粗细是以号数(xxAWG)来表示的，数口越小表示线径愈粗，所能承载的电流 就越大，反之则线径越细，耐电流量越小。例如说：12号的耐电流量是20安培，最大承受功率 是2200瓦，而18号线的耐电流量则是7安培，最大承受功率是770瓦。为什么AWG号数越小直径反而越大？如这么解释你就会明口，固定的截面积下 能塞相同的AWG线的数量，toll#AWG号数可塞11根ffnl5#AWG号数可塞15根，自然的15#AWG的单 位线径就较小。美规线径值单一导体或群导体【各正值或负值】的线径值(Gauge)是以圆或平方厘米5於) 量测而得，平方厘米不常用在量测线径值，由于牵涉到不正确

2、，因一般大部份的导体形体，包 含长方形及其他怪异形状。因此我们拿全部的量测以圆平方厘米(c/in)为参考值群导体计算的方法或公式：加上单一导体的线径值总和，并比较上表求得。如果值落入两者之间，取比较少的值。40股群导体线的线径值为，如每一芯为24 Guage = 40 x 405 c/m = 16 200 c/m = 9 AWG( 得出值落入12960c/m和16440c/m之间)快速求得线径值的方法：两条(AWG)相加时，该单一线径值减3.ex.18AWG = (18-3=)15AWG三条(AWG)相加时，该单一线径值减5.ex.24AWG = (24-5=)19AWG四条(AWG)相加时，

3、该单一线径值减6.ex.10AWG = (10-6=)04AWG只采用此方式为大原则请记得快速求得线径值的方法 一些案例也许边际会不正确,AWG标准线径规格对照表AWG NumberO InchOnunO mm2|Resistance Ohin/m4/0 = 00000.46011.7107 II 0.0001613/0 = 0000.41010.485.00.0002032/0 = 0003659.2667.40.0002561/0 = 00.3258.25-153.50.00032310.2897.3542.40.00040720.2586.5433.6O.OOO51330.2295.83
