<p>[Summary] Not only to improve insulating properties, heat resistance, mechanically physical properties and the like of an insulating composition but also to lower viscosity of an insulating material (insulating polymer component) so as to improve a productivity thereby raising reliability of an insulating product. [Object] Upon using an insulating material including at least an insulating polymer component, this insulating material is heated to be three-dimensionally crosslinked thereby to obtain an insulating composition which is applied for an insulating constitution of a voltage equipment. The insulating polymer component is formed of a vegetable oil such as linseed oil or the like. The vegetable oil undergoes esterification thereby to obtain fatty acid which is epoxidized thereby obtaining epoxidized vegetable oil ester which is applied for. As components other than this epoxidized vegetable oil ester, for example, filler (silica or the like), hardening agent (polyphenol or the like), hardening accelerator (imidazole or the like) may be suitably blended.</p> |
