The insulation barrier comprises a frame (14) at least partly surrounding the insulating sheet, and a plurality of spring-loaded fastening members (35) for fastening the frame (14) to the tap changer tank (3). The fastening members (35) are pivotably arranged relative the frame and the tap changer tank to allow relative movements between the frame and the tap changer tank.
