AWG線規(guī)計算 - 無圖版

國內(nèi)廠家多以平方表示電纜截面﹐而歐美等常以線規(guī)號（AWG)表示電纜規(guī)格﹐下面上傳一個導體線規(guī)計算公式﹐給國內(nèi)企業(yè)做參考: AWG計算.xls

你能具體的解釋一下里面各個數(shù)字的含義嗎?

cuijiude --- 2006-07-07 15:59:59

n根數(shù)﹐d單絲直徑﹐area面積（圓彌爾）﹐AWG線規(guī)號

明白了嗎

cuijiude --- 2006-07-08 10:36:22

excel文檔﹐輸入就可以計算了﹐很方便

不錯的貼子，AWG線規(guī)是按一定的規(guī)律制定的，對不同導體直徑進行標識，可以用公式確定。

改進！

cuijiude --- 2006-07-15 01:03:36

但要注意﹐就象中國的平方數(shù)一樣﹐相近的直徑也可能被稱為同一線規(guī)號﹐也就是說﹐同一個線規(guī)號﹐導體的直徑可能會有一點不同。

HI根據(jù)不動的安規(guī)(ul444,ul62,ul758相同的AWG數(shù)時要求的最小截面積不同)相應AWG數(shù)之最小截面積,求單根導體最小直徑的公式也搞成電子公式噻 !!!!

數(shù)字通信 --- 2006-08-08 14:20:17

算出的有誤的，為什么只有雙數(shù)的線規(guī)，而沒有單數(shù)的線規(guī)！公式在加以大大修改呀！

刪蒢記憶 --- 2006-08-11 11:17:42

關于AWG線規(guī)的計算，大家可以根據(jù)導線的導體結(jié)構來計算一下，我一般也是這么做的

一些型號的導線的導體結(jié)構，我們大家都已經(jīng)知道了，就無須再去計算它的面積了，UL標準也有

cuijiude --- 2006-08-11 16:52:24

實際使用的大部分是雙數(shù)線規(guī)﹐原因我也不清楚

樓主看到此貼該給加個威望送朵花吧�。

UL的奇數(shù)號線規(guī)用的比較少，但也是有使用的，比如，15AWG，13AWG出現(xiàn)的幾率想對比較高

slj8106 --- 2006-11-14 08:14:26

用mil可以直接計算出線規(guī)AWG。有一個公式。但AWG不能精確轉(zhuǎn)換成mil。

請教各位,有沒有曲線長度的計算公式,例如:曲線長120MM,線徑OD:4.0MM,曲線直徑:12MM,曲線一端留長120MM,另一端留長180MM,要卷成這種規(guī)格的線實際需要多長的線,TKS!!!

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(shù)據(jù)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(guī):UL62

這個是AWG，還是BWG？

AWG不應該是從50到4/0嗎？
