This invention relates to an isolator for a large-sized static induction apparatus such as transformer and reactor. The static induction apparatus wherein a sound insulation panel is mounted through an elastic body on a reinforcing channel which is disposed on a side plate of an oil tank receiving a main device of the apparatus therein, is characterized by disposing a looped weight beam near that part of the sound insulation panel on which the elastic body is installed. With such construction, noise can be effectively reduced while imparting a satisfactory supporting strength to the mounting part of the sound insulation panel.
