Cambiador de tomas sin tensión
Cambiadores de tomas sin tensión lineales y giratorios para una amplia serie de aplicaciones
Los cambiadores de tomas sin tensión se utilizan para ajustar la tensión de los transformadores de aceite. A diferencia de los cambiadores de tomas bajo carga, el ajuste de la toma del devanado deseada debe realizarse con el transformador apagado.
Ofrecemos una amplia gama de cambiadores de tomas sin tensión para transformadores de distribución, transformadores de redes de muy alta tensión y aplicaciones especiales.
