Abstract
According to an embodiment, a gas insulation apparatus (e.g., a gas circuit breaker) includes a high-voltage unit, a zeolite and an insulation gas in a closed vessel. The insulation gas is CO2 gas or a gas including CO2 gas as the main component. The zeolite is contained in a zeolite case and is placed under an insulation gas atmosphere. CO2 is adsorbed on the zeolite before use of the gas insulation apparatus.
