Tabla de grosores AWG (American Wire Gauge)

Tema: Tablas |

La presente tabla muestra la equivalencia entre los grosores AWG y el sistema de medida inglés (imperial).

Dia-mils = diámetro en mils (1 mil = 1e-3 pulgadas)
TPI = turns-per-inch, vueltas por pulgada. útil para el cálculo de bobinados.
Dia-mm = diámetro en mm
Circ-mils = área de la sección recta en mils circulares (1 circ-mil = d^2 siendo d el diámetro en mils).
Ohms/kft = ohms por 1000 pies
Ohms/Lb = Ohms por libra de peso.
Lb/kft = Libras por 1000 pies
*Amps = Tasa de corriente admisible basado en 750 circ-mils por ampere.
MaxAmp = Corriente máxima admisible basado en 500 circ-mils por ampere.

1 Ft = 0.3048 m
1 inch = 0.0254 m
1 Lb = 453.5924 g

    buenas tardes mi inquietud es como sacan todos eso valores de tabla correspondiente a cada calibre

  3. Comment by Jolyn — 9 July 2011 @ 2:06

    Cool! That’s a celevr way of looking at it!
