Conversación sobre el tamaño del conductor (AWG/SWG en mm)

En el cable, la dimensión del hilo conductor se mide en mm, pero el área de la sección transversal o el tamaño del conductor se expresa en mm2 (mm2), AWG (calibres de cable americanos) y SWG (calibres de cable estándar).

Podemos entender fácilmente la conversión de SWG/AWG a mm y mm2 a partir de la tabla dada.

SWG = CALIBRE DE CABLE ESTÁNDAR (BRITÁNICO)
B & S = MARRÓN Y AFILADO
AWG = CALIBRE DE CABLE AMERICANO

CSA (en mm2) = [0,785 x (D)^2] x número de hilos

Ejemplo 1

Para el tamaño 20 AWG, CSA es 20 AWG = 0,81 mm
Número de hebras = 1
CSA = 0,785 X 0,81 X 0,81 X 1 = 0,51 mm2

Ejemplo 2

Para el tamaño 3 X 22 SWG, CSA es el número de hebras = 3
Tamaño de cada hebra = 22 SWG 22 SWG = 0,71 mm
CSA = 0,785 X 0,71 X 0,71 X 3 = 1,19 mm2

En cable, los tamaños de conductor más populares utilizados en estilo AWG son 26, 24, 22, 20, 18 y 16. Estos pueden ser de tipo sólido o multifilar.

En estilo SWG: 3X22 SWG, 1 X 22 SWG, 1 X 30 SWG, 1 X 24 SWG

Single Color vs Two Color Pyrometers: Which One Actually Works for Your Process?

If you’re selecting a pyrometer based only on temperature range, you could be solving the wrong problem. In practice, measurement errors are often caused by changing emissivity, dust, smoke, moving targets, or partially blocked sight paths rather than the instrument itself. That’s why the debate between single-color and two-color pyrometers continues across industries such as […]

Pirómetro vs. Termopar: ¿Cuál es la mejor opción para medir la temperatura?

Precision in temperature measurement plays an integral role in the efficiency, quality, and safety of many industrial processes. The decision between the pyrometer vs thermocouple is not a question of declaring one technology “better” than the other; rather, it is a question of being able to identify which measurement principle will yield optimal results for […]

SmarTrack Data Logger: How Our Thermal Profiling System Has Evolved

If you’ve been profiling furnaces, ovens or heat-treatment lines with a SmarTrack data logger for a while, you already know why thermal profiling matters — you can’t control what you can’t measure inside a closed, hot process. What’s changed recently is how well the logger measures it. After several rounds of field feedback and product […]
