Abstract

PURPOSE:To obtain a high insulating characteristic of a resin molded coil by a method wherein a resin consisted of an epoxy resin composite containing a sort of acid anhydride is made to include 5-30wt% of resin component to be hardened by the irradiation of ultraviolet ray is used to mold a coil with resin. CONSTITUTION:When a high tension cylindrical elemental coil 1 for the use of dry type molded transformer, etc., is to be produced, a core insulating layer 3 consisted of aromatic polyamide nonflexible cloth is wound around on a winding core 2 to an appointed thickness. An enameled copper wire 4 and an interlayer material 5 consisted of polyester flexible cloth are alternately wound on it rolling in a packing 8 consisted of aromatic polyamide nonflexible cloth between them to form a multilayer winding, the outest side is covered with an outer circumferential insulating layer 6 consisted of the same aromatic polyamide nonflexible cloth and putty 7 is applied to the both end parts. Then it is treated by impregnation with a mixture consisted of bisphenol A epoxy containing methyltetrahydraphthalic acid anhydride and 5-30wt% of ultraviolet ray hardening type epoxy acrylate containing benzoin ethyl ether, and after the surface is irradiated with ultraviolet ray being made to rotate, it is heated to harden.
