Abstract

PURPOSE: To rigidly hold a conductor for an oil-immersed electric equipment and enhance the reliability of the equipment by employing concurrently an insulating material which contracts its volumes by a drying treatment and another insulating material which swells its volume due to the oil-immersion after drying treatment.
CONSTITUTION: An insulating material 30 contracting in volume by a drying treatment is formed, for example, of kraft paper or pressed board or the like, and an insulating material 32 slightly contacting in volume due to the drying treatment but increasing in volume due to oil-immersion is formed of laminated paper prepared by laminating plastic or plastic and kraft paper in a thin plate. Insulators are hermetically contacted between other members associated by oil-immersion by interposing the insulators at the oil-immersed equipment so as to rigidly hold the internal equipment and insulating capacity can be secured to improve the reliability.
