  • Circuit Breakers: Air vs. SF6 Insulated - Electric power

    -breakers are named with their interrupting media: vacuum, SF6, air-blast, oil, air.-heaters supplied in the station breakers are mostly used to prevent internal condensation. however, SF6 brakers are supplied with tank heaters to prevent liquidification of SF6 gas under extreme cold temperatures.
