Portable SF6 transfer unit - GTU-10 - WIKA Canada compact dimensions of the model GTU-10 are ideal for mobile use. The fields of application range from the storage of SF 6 gas in gas tanks to the filling of SF 6 gas-insulated switches. During storage of the SF 6 gas, the compressor can liquefy the gas in the storage vessel. Thus, the maximum storage capacity of a gas cylinder can be used.

Green Gas for Grid - g3 - SF6 Free Solutions 6 SF6 (or Sulphur Hexafluoride) had been the standard gas used inside high voltage electrical equipment as an insulating and arc-quenching medium.
