AWG Table ,
AWG規格表
 
美國線規（American wire gauge，縮寫為AWG）
數字代表相同面積下，能塞進的AWG線數目。線規數字越小，表示線材直徑越粗，所能承載的電流就越大；反之，線規數字越大，表示線材直徑越細，所能承載的電流就越小。

AWG表適用於單根、實心、圓形的導線。雙絞線的AWG值由所有導線的總橫截面積決定，並且由於雙絞線之間總是有一些空隙，導致相同的AWG值雙絞線的直徑總是略大於單根導線的直徑。

 Unparalleled Performance
Belden is one of only a very few cable
manufacturers to draw and anneal its
own conductors. This is a time-consuming
process, but it allows us to ensure signal
integrity, as well as proper physical
characteristics.
In addition, the standards under which we
design and manufacture our fiber optic
cabling are among the strictest in the
industry. The result is a comprehensive
offering of products which give
unparalleled performance and can
satisfy your most demanding operating
and environmental challenges.
