sf6 o2 Service for extra high Voltages

Modern, state of the art, High Voltage and Extra High Voltage switching devices (e.g. circuit breakers) use SF6 as an arc-quenching medium, almost exclusively. Another design is the SF6 insulated metal-enclosed switchgear, where the SF6 gas provide the main insulation of the equipment.
