SF6 gas Mixtures Vacuum Charging separating unit

This means that the circuit-breaker contacts separate in air. High voltage installations e.g. at 6.6 kV and 11 kV generally use the vacuum interrupter type or gas-filled (sulphur hexafluoride – SF6) breakers. In a vacuum interrupter the contacts only need to be separated by a few millimetres as the insulation level of a vacuum is extremely high.
