1、AWGAWG 标准线径对照表标准线径对照表线径的粗细是以号数(xxAWG)来表示的，数目越小表示线径愈粗，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白，固定的截面积下能塞相同的AWG线的数量，如11#AWG号数可塞11根而15#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(mm2)量测而得，平方厘米不常用在量测线径值，由于牵
2、涉到不正确，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/m)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.2 x 18 AWG=(18-3=)15 AWG三条(AWG)相加时，该单一线径值减5.ex.3 x 24 AWG=(24-5=)19 AWG四条(AWG)
3、相加时，该单一线径值减6.ex.4 x 10 AWG=(10-6=)04 AWG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，只采用此方式为大原则AWGAWG 标准线径规格对照表标准线径规格对照表AWG NumberAWG Number4/0=00003/0=000O InchO Inch0.4600.410O mmO mm11.710.4O mm2O mm210785.0Resistance Ohm/mResistance Ohm/m0.0001610.000203精选文库2/0=001/0=0123456789AWG NumberAWG Number101112131415161
