要約(英語): We have been studied the use of ice, solidified H2O, as electrical insulating material at cryogenic temperature. Ice has excellent electrical breakdown strength. In addition, ice is environment-friendly material and easy to be molded into various shape because it is liquid at room temperature. However, ice has the several problems as electrical insulating material; one is that voids or cracks are easily formed.In this paper we tried to improve the A.C. breakdown strength of ice by mixture of water-soluble material, namely by producing solidified aqueous-solution. We chose alcohol as water-soluble material; namely ethanol, 1-propanol, 2-propanol, propylene glycol and glycerin. We examined the A.C. breakdown strength of solidified alcohol aqueous-solution at 77 K. As the results, the A.C. breakdown strength of solidified 2-propanol aqueous-solution shows the highest, 64% higher value than ice.
