PROBLEM TO BE SOLVED: To provide a composite film for a conservator of an oil-immersed transformer having a high peel strength between an intermediate layer composed of EVOH film or the like and a nylon cloth layer. SOLUTION: This composite film 10 for a conservator used in an oil-immersed transformer has a structure in which a nylon cloth layer 2 is bonded to both surfaces of an intermediate layer 2 composed of EVOH film or the like with an adhesive 4, and an outer layer 3 composed of a nitrile rubber or the like is bonded to the outer surface of each of nylon cloth layers 2. The adhesive 4 is an aqueous solution dissolving a polyvinyl alcohol resin. COPYRIGHT: (C)2010,JPO&INPIT |
