国内厂家多以平方表示电缆截面﹐而欧美等常以线规号(AWG)表示电缆规格﹐下面上传一个导体线规计算公式﹐给国内企业做参考: AWG计算.xls

不错的贴子,AWG线规是按一定的规律制定的,对不同导体直径进行标识,可以用公式确定。

改进!

但要注意﹐就象中国的平方数一样﹐相近的直径也可能被称为同一线规号﹐也就是说﹐同一个线规号﹐导体的直径可能会有一点不同。

HI根据不动的安规(ul444,ul62,ul758相同的AWG数时要求的最小截面积不同)相应AWG数之最小截面积,求单根导体最小直径的公式也搞成电子公式噻 !!!!

关于AWG线规的计算,大家可以根据导线的导体结构来计算一下,我一般也是这么做的

一些型号的导线的导体结构,我们大家都已经知道了,就无须再去计算它的面积了,UL标准也有

用mil可以直接计算出线规AWG。有一个公式。但AWG不能精确转换成mil。

even  more, let me share this....

By definition, No. 36 AWG is 0.0050 inches in diameter, and No. 0000 is 0.4600 inches in diameter. The ratio of these diameters is 92, and there are 40 gauge sizes from No. 36 to No. 0000, or 39 steps. Using this common ratio, wire gauge sizes vary geometrically according to the following formula: The diameter of a No. n AWG wire is

d_n = 0.005~\mathrm{inch} \times 92 ^ \frac{36-n}{39} = 0.127~\mathrm{mm} \times 92 ^ \frac{36-n}{39}

the gauge can be calculated from the diameter using

n = -39\log_{92} \left( \frac{d_{n}}{0.005~\mathrm{inch}} \right)+36 = -39\log_{92} \left( \frac{d_{n}}{0.127~\mathrm{mm}} \right)+36 

and the cross-section area is

A_n = \frac{\pi}{4} d_n^2 = 0.000019635~\mathrm{inch}^2 \times 92 ^ \frac{36-n}{19.5} = 0.012668~\mathrm{mm}^2 \times 92 ^ \frac{36-n}{19.5}.

Sizes with multiple zeros are successively larger than No. 0 and can be denoted using "number of zeros/0", for example 4/0 for 0000. For an m/0 AWG wire, use n = −(m−1) = 1−m in the above formulas. For instance, for No. 0000 or 4/0, use n = −3.

The ASTM B 258-02 standard defines the ratio between successive sizes to be the 39th root of 92, or approximately 1.1229322 ASTM B 258-02 also dictates that wire diameters should be tabulated with no more than 4 significant figures, with a resolution of no more than 0.0001 inches (0.1 mils) for wires larger than No. 44 AWG, and 0.00001 inches (0.01 mils) for wires No. 45 AWG and smaller.

AWG裡面的數據是標稱值.如14AWG,對應截面2.08MM2,單根最小OD(36AWG)0.125MM,最大(30AWG)0.254MM.作為製程控製.成品的最終仲裁為電阻

安規:UL62

这个是AWG,还是BWG?

AWG不应该是从50到4/0吗?
