It is known that a capacitor is formed by curing. However, when such a laminated insulator is used for a long time in an environment where moisture is present, the infiltration of moisture sometimes deteriorates the insulation characteristics.

り、従来品と同様に用いることができる。As described above, in the laminated insulator of the present invention, the surface of the metal foil electrode concentrically wound around the mandrel together with the thin leaf-shaped insulator is surface-treated by a method such as a primer treatment, an acid treatment, or an anodizing treatment. Since the surface of the metal foil electrode is covered with a substance having a stronger affinity for water, even if moisture reaches near the surface of the metal foil electrode due to long-term use, There is no direct reaction with the surface of the metal foil electrode. For this-OH as above
Moisture resistance can be remarkably improved without breaking the base or causing corrosion of the metal foil electrode due to Cl or the like. Moreover, the laminated insulator of the present invention has the same electrical characteristics as the conventional product and can be used in the same manner as the conventional product.

First, in order to perform the silane treatment among the primer treatments, for example, a solution prepared by dissolving 0.5% by weight of aminosilane in ethyl alcohol is used as a metal of aluminum. It may be applied to the foil electrode, or the metal foil electrode may be dipped in this solution and then dried. In order to perform the primer treatment with a resin, for example, the metal foil electrode may be immersed in a phenoxy methyl ethyl ketone solution of Ciba Co., Ltd. and then dried by heating. In order to further perform the primer treatment with a rubber adhesive, for example, a methyl ethyl ketone solution of a nitrile rubber / phenol resin adhesive may be applied to the surface of the metal foil electrode and then dried.

ものである。As described above, according to the present invention, by carrying out the surface treatment of the metal foil electrode for forming the capacitor, the epoxy resin and the metal foil electrode are not separated from each other even when moisture reaches near the surface of the metal foil electrode. The peeling did not occur, and as shown in the graph of FIG. 1 showing the results of the hot water immersion test, the adhesive strength was far less reduced than the conventional untreated product. Therefore, the laminated insulator of the present invention does not easily deteriorate in insulation characteristics even when it is used for a long time in an environment where water is present, and is excellent in moisture resistance used in through bushings, gas circuit breaker partial pressure capacitors, etc. As a laminated insulator, it greatly contributes to industrial development.
