PROBLEM TO BE SOLVED: To provide a cast insulator for a gas switch that can prevent the occurrences of interfacial peeling and a crack while improving heat resistance, and an insulation spacer comprising the same.SOLUTION: A cast insulator for a gas insulated switch comprises a resin having a uniform phase formed so that polycyclic aromatic epoxy resin, bisallylnadimide, thermoplastic resin with a glass transition temperature of 120°C or more are made compatible with each other. There is also provided an insulation spacer comprising the cast insulator. |
