Title:
LAMINATED INSULATOR
Document Type and Number:
Japanese Patent JPH04286803
Kind Code:
A
Abstract:

PURPOSE: To provide a laminated insulator where the tensile stress does not exist inside and there is no fear of crack occurrence even if thermal cycle is applied.

CONSTITUTION: Cloth 3, which is woven repeating the rough and dense for the weaving intervals of the weft 2, is wound, as a base material, on a cylindrical core metal 4, and is impregnated with thermosetting resin and then it is hardened. Since the rigidity in the circumferential direction of the base material is small, it can also be shrunk in the circumferential direction, and the tensile stress does not occur in the radial direction. Moreover, a capacitor can be made by winding a thin sheet-shaped electrode inside coaxially.
