sulfur hexafluoride Storage Systems for Transformers

This project was designed to evaluate the potential for providing a superior gasoil insulating and cooling system for liquid filled transformers. The potential benefits of using the electronegative gases, sulfur hexafluoride, sf 6, or hexafluorethane, C 2 F 6, in place of nitrogen gas normally used in gas-oil filled transformers were examined.
