AMPACIDADES DE LA ALEACIÓN DE COBRE C11000 BARRAS DE BUS
Las ampacidades en la tabla a continuación son para barras de bus que tienen una emisividad de 0.4. Esto se observó en muestras expuestas durante 60 días en un entorno industrial, y probablemente sea idéntico al de las barras de bus en servicio.
