Válvula de alivio de presión
Válvulas de alivio de presión de varios tamaños (1″-6″)
Los cortocircuitos son una causa frecuente de averías y problemas en los transformadores. Pueden provocar un desarrollo masivo de sobrepresión en el depósito y en el cambiador de tomas del transformador. Las válvulas de alivio de presión protegen de forma fiable y segura los transformadores de distribución medianos y grandes, las bobinas eléctricas, los transformadores de potencia y los cambiadores de tomas en caso de aumentos repentinos de presión en el sistema de aceite.
