Abstract

PURPOSE:To increase the combining strength and to enhance reliability, by performing mutual combining of insulating tubes, liners, and an end part insulator by the adhesive power of resin and the mechanical combining power of a fibrinous material. CONSTITUTION:The inner liner 2 comprising the fibrinous material is formed on the inner insulating tube 1 which is formed by impregnating thermosetting resin. A coil main body 3 is formed thereon via interlayer insulators 5. The outer liner 6 which is formed by the same material as that of the inner liners 2 and the outer insulating tube 7 which is formed by the same material as that of the inner insulator 1 are provided. By prelimnarily drying said device, the impregnated resin in the insulating tubes 1 and 7 is impregnated into the liners 2 and 6, and the insulators 1 and 7 and the liners 2 and 6 are strongly combined. Then the thermosetting resin is injected, heated, and cured, and the liners 2 and 6 and the end part insulator 9 are strongly combined.
