| Outline of Final Research Achievements |
In 2010, before the start of this research project, the principal investigator successfully developed a new kind of electrical insulating material - a nanocapsule composite insulating material. This material is a compound of nanocapsules, which are nanosized-structure particles encapsulating gas, and polymers, and it demonstrates low permittivity characteristics. In this research project, the investigator further clarified its dielectric breakdown strength and undertook foundational research to explore the potential applicability of this nanocapsule composite insulating material to electrical power equipment. Moreover, the investigator developed a three-dimensional electric field analysis model in which nanocapsules are randomly distributed and oriented within the resin. Through analyzing the discharge initiation electric field of the nanocapsules, it was demonstrated that these nanocapsules do not serve as defects that decrease the dielectric breakdown strength.
