SF6 insulated Analysis for 220kv

SF6 insulated Analysis for 220kv

SF6 electrical circuit breaker is a device where a current is operating with SF6 or Sulphur Hexafluoride being carried on its contacts. It breaks off the power when there's an excessive electricity supply that exceeds the allowed voltage to prevent circuit overload.
