The high efficiency insulation panel for transformer construction is needed in residential area because the making noise from transformer substation in side of city is appeared a lost of problem by increasing to conserve the living environment. Therefor in this paper, first the vibration and noise characteristic of existing insulation panel is analyzed according to attached material, cork and sponge-type. Second the insulation of sound performance is compared between the existing insulation panel. And high efficiency insulation panel that is proposal in this paper.

Highly damped insulation panel for transformer construction is needed in residential area because the making noise from transformer substation in inner city is appeared a lost of problem by increasing to conserve living environment. Therefor in this paper, the vibration and noise characteristic effect of cork-type and sponge-type that is attached between insulation panel and enforce beam in transformer is analized using real size transformer experimentally.
