• Sulfr hexafluoride: An excellent dielectric gas in controlled environments

    sf 6: An excellent dielectric gas in controlled environments. Sulphur hexafluoride gas (Sulfr hexafluoride) has been the primary insulating medium in high-voltage electrical switchgear and controlgear for 40 years. Fingrid prevents the potent greenhouse gas from escaping into the atmosphere by constantly monitoring the equipment where it is used.
