Abstract
A power transformer/reactor immersed in oil including a transformer/reactor core and windings accommodated in a tank including a tank base plate and tank walls. A foundation supports the tank. An elongated continuous band forming a closed frame is arranged between the base plate and the foundation. An outer periphery of the base plate extends outside an inner periphery of the frame and thereby encloses an air volume within the frame, the base plate and foundation. The tank support reduces sound emitted from the transformer/reactor.
