摘要： PROBLEM TO BE SOLVED: To prevent water, dust, etc., for infiltrating the inside of a coil by winding an outer circumferential coating material around a coil outer circumferential part, and a eliminating the exposed part of a wiring by sealing an end part by additional reaction type silicone resin. SOLUTION: A high-voltage coil or a low-voltage coil is prepared by winding an electrical insulation coating material 5 on a conductor 4, winding it to an insulating tube 6 thereafter, winding an outer circumferential coating material 7 to an outer circumferential part, hardening a semi-hardening resin used in each member through a heating treatment, and then filling silicone resin 8 thereinto. An exposed part in a wiring is eliminated, water, waste, dust, etc., are prevented from entering an inside of a coil, and reliability and appearance are improved by filling the outer circumferential part of a coil with an outer circumferential coating material and filling an end part with additional reaction type silicone resin. In the coil, the entire body to an inside of a coil is not molded by silicon resin unlike as in a mold transformer, but the both end parts of a coil alone are sealed by additional reaction type silicone resin. Therefore, the operation for having silicone resin infiltrate into the inside of a wiring can be omitted.

摘要： PROBLEM TO BE SOLVED: To provide an insulation spacer excellent in dielectric withstand volt age and having an anti-HF(hydrogen fluoride) property by introducing such an arrangement that the content of a filler differs in the direction across the spacer thickness. SOLUTION: An insulation spacer 3 supports a high voltage conductor 2 installed in a vessel which is filled with an insulation gas. The spacer 3 is made of a base resin consisting of epoxy resin, acid anhydride, and a hardening accelerator, to which a filler is added, followed by agitation on a vacuum at a certain temp. so that a resin composition for molding is prepared, and this is injected into a die and subjected to a hardening process with heat. At this time, the content of the filler is distributed as differing in the direction across the thickness of the spacer, wherein the content 2mm deep from the spacer surface should be below 20vol.%.
