sulfur hexafluoride Insulated Equipment for Transformers

Fugitive emissions of SF6 can escape from gas-insulated substations and switch gear through seals, especially from older equipment. The gas can also be released during equipment manufacturing, installation, servicing, and disposal. PFCs are sometimes used as dielectrics and heat transfer fluids in power transformers.
