Abstract

PURPOSE:To aim at improvement in an electrical characteristic by laminating a sheet of electrical insulating paper and a biaxial orientation polypropylene film laminated via a specific polyolefine bonding agent with this specific polyolefine bonding agent. CONSTITUTION:In case of an insulating material laminated by sticking sheets of electrical insulating paper made up of using a natural or synthetic fiber together on both sides of a biaxial orientation polypropylene film, a polypropylene film consists of a laminated biaxial orientation polypropylene film made up of laminating at least more than two sheets of biaxial orientation polypropylene films for adhesion together via polyolefine at a temperature of 100-150 deg.C in melting point. And, this polyolefine at the melting point 100-150 deg.C is used for adhesion between the laminated biaxial orientation polypropylene film and the electrical insulating paper, and that more than three pieces of imino type and/or amino type nitrogen atoms per 100 have in an outer layer part ranging from the surface facing to the electrical insulating paper of the polyolefine layer to 100Angstrom . With this constitution, voltage resisting and oil immersion characteristics are improved.
