Handheld SF6-Air monitoring in high electrical switchgear

Handheld SF6-Air monitoring in high electrical switchgear

Since 1960, SF6 (sulfur hexafluoride) is used in electrical equipment (switchgear and devices) and also in other applications like arc furnaces, window insulation, car tires and sport shoes! SF6 is used in electrical equipment because of its dielectric strength, excellent insulating properties and its arc-suppression capabilities.
