Comparison of CF3CHCl2 gas with SF6 gas as an alternative substitute for gas insulated switchgear equipment

Sulfur hexafluoride is a gas that used as a medium for insulation on electrical equipment. One use of Sulfur hexafluoride gas in high voltage equipment used on equipment Gas Insulated Switchgear. The use of Sulfur hexafluoride gas in Gas Insulated Switchgear equipment has the potential because of Sulfur hexafluoride gas as an insulating gas that can withstand the breakdown voltage reaches 785 kV. Besides having the advantage as an insulating material in Gas Insulated Switchgear, Sulfur hexafluoride gas is known as one of the gas contributors to the greenhouse effect. Further, according to the Kyoto Protocol, the use of Sulfur hexafluoride gas should be limited and gradually be reduced until alternative gas to Sulfur hexafluoride gas discovered and commercialized broadly. Gas alternatives that have the potential to replace Sulfur hexafluoride gas in Gas Insulated Switchgear equipment are Dichlorotrifluoroethane gas. Gas Dichlorotrifluoroethane has reportedly great potential as an insulating gas because it has higher insulation capability than Sulfur hexafluoride gas, and is part of the gas that is recommended in the Kyoto Protocol. Gas Dichlorotrifluoroethane has doubled electronegativity value greater than Sulfur hexafluoride gas as the principal condition as insulating gas and has a value of Global Warming Potential and Ozone Depleting Potential lower than Sulfur hexafluoride gas.
