Wire gauge, tensil-strebgth, DC-registance calculation
Ordinary, next two gauging systems are used with electrical wire and cables.
AWG (American Wire Gauge)
- It is known as BS (Brown & Sharp wire gauge). The AWG guging system
is defined as geometrical progression because of drawing machanism nature.
The 36 AWG is defined as 5 mil diameter, and the 4/0 AWG is defined as
460 mil diameter. (See ASTM B 258)
- represents diameter of solid wire in mil (1/1000 inch) or
cross-sectional area in circular mil.
milimeter wire gaging system
- represents diameter of solid wire in mm or cross-sectional area of stranded wire
in mm^2 (square mm).
Most of conductors is composed with copper. Most impotant parameter of
conductors are cross section which determins DC-resistance and most of
