hexafluoride Transfer 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.

    Jan 25, 2017Sulfur hexafluoride (SF6) gas is an alternative to air as an interrupting medium. SF6 is a colorless nontoxic gas, with good thermal conductivity and density approximately five times that of air. The principle of operation is similar to the air blast breakers, except that the SF6 gas is not discharged into the atmosphere.
