Summary:To efficiently manufacture a high-performance insulation structure having high development suppressing effect of an electric tree.SOLUTION: A resin manufacturing method for manufacturing resin impregnated in an insulation structure formed on an outer peripheral portion of a conductor includes: a chemical modification step of chemically modifying a surface of nanofillers; an epoxy-resin mixing step of adding epoxy resin and a polymerization accelerator to the nanofillers and shear-mixing the same to generate a mixture; and a curing agent mixing step of mixing an acid anhydride-curing agent with the mixture after the epoxy-resin mixing step.SELECTED DRAWING: Figure 10 【課題】電気トリーの進展抑制効果が高い高性能な絶縁構造を効率的に製造する。【解決手段】導電体の外周部に形成される絶縁構造に含浸されるレジンを製造するレジン製造方法であって、ナノフィラー表面の化学的修飾を行う化学的修飾化工程と、ナノフィラーにエポキシ樹脂及び重合促進剤を加えてせん断混合して混合物を生成するエポキシ樹脂混合工程と、エポキシ樹脂混合工程後の混合物に、酸無水物硬化剤を混合する硬化剤混合工程と、を含む。【選択図】図１０
