AWG CABLE DESCRIPTION　
American Wire Gauge

--------------------------------------------------------------------------------

The table below lists the Aluminum wire Characteristics for different gauges of the American Wire Gauge [AWG]. The American Wire Gauge provides a means of specifying wire diameters. For each different AWG [wire size] the table provides the Diameter [in mils], Diameter [in Circular mils], the resistance per 1000 foot, the Fusing current, and Pounds per Foot [NUMBER of feet required to weigh 1 pound]. Read the notes below the table to determine how the Ampacity was derived. The larger the AWG NUMBER, the smaller diameter wire. The table is based on an ambient temperature of 25oC. Conductor size is based one or more of the following considerations:
Current carrying capacity [inducing a rise in wire temperature, in high-voltage lines], SHORT CIRCUIT current, or Voltage drop [LONG low voltage lines].

AWG CABLE DESCRIPTION

American Wire Gauge

The table below lists the wire Characteristics for different gauges of the American Wire Gauge [AWG]. The American Wire Gauge provides a means of specifying wire diameters. For each different AWG [wire size] the table provides the Diameter [in mils], the resistance per 1000 foot, the current carrying capability [Ampacity], and Pounds per Foot [NUMBER of feet required to weigh 1 pound]. Read the notes below the table to determine how the Ampacity was derived. The larger the AWG NUMBER, the smaller diameter wire. The table is based on an ambient temperature of 25oC. Some of the STANDARD wire sizes used in a NUMBER of Interface Buses [for data lines] are #22AWG, #24AWG, #26AWG, and 30AWG. A listing of Electronic bus STANDARDs are located on the Buses page. Another table near the bottom of the page provides copper current carrying ability [Ampacity] for Teflon insulated wire. Conductor size is based one or more of the following considerations:
Current carrying capacity [inducing a rise in wire temperature, in high-voltage lines], SHORT CIRCUIT current, or Voltage drop [LONG low voltage lines].

應(yīng)該說(shuō)這是比較爽的資料
請(qǐng)大家多頂頂，以便更多的朋友了解。

說(shuō)起來(lái)大家平時(shí)可能已經(jīng)注意到，即便是中國(guó)線(xiàn)規(guī)，還是有不少人不了解的。

不過(guò)，實(shí)際中的線(xiàn)規(guī)遠(yuǎn)不只這么簡(jiǎn)單，這里只是一個(gè)簡(jiǎn)要的了解，圖個(gè)拋磚引玉吧。

另外，有興趣的朋友不妨翻譯一下，我這段時(shí)間有任務(wù)，顧不上來(lái)了.......
