Abstract

PURPOSE: In a transformer constituted that a sound-proof eave is arranged on the upper part of the oil tank and engaged with a sound-proof wall, a soundproof cover is added on the upper surface of the oil tank which is not covered with the sound-proof wall, and supported on the sound-proof wall, and thus the reduction of noise to the same degree in the double tank construction is achieved.
