PURPOSE:To obtain a insulating enclosure without gap preferably draped with the uneven surface of a coil by covering the entire periphery of the coil with an insulator produced by bonding a base material hardly impregnating resin and a non-woven fabric preferably draping via flexible resin and impregnating and hardening the synthetic resin. CONSTITUTION:Room temperature curable or a heat curable adhesive being flexible at room temperature is coated on a base material having low impregnation with resin under normal pressure and high drapability, long fiber of synthetic resin is entangled to bond non-woven fabric of strip shape. In this case, it is important not to impregnate the resin to the back surface of the bonding surface of the fabric. For that purpose, the adhesive resin amount is, for example, 8-24% to the entire weight. In this manner, a insulating enclosure in which the resin is preferably draped with the uneven surface of the coil and no gap for causing the wrinkle and voids even with small tensile strength with the flexibility of the insulator can be obtained. |
