  • SF6 Gas gas-filled for Light Rail

    SF6-filled Management detecting. Aug 08, 2017SF6 gas in switchgear SF 6 was discovered around the turn of the twentieth century and, by the 1950s, the electric power industry in the USA widely praised SF 6 as a highly favourable gaseous dielectric medium in high and medium-voltage circuit breakers, switchgear, gas

  • SF6 Lasercheck P3:vac - ISM Deutschland GmbH

    For integral leak testing, the SF6 filled test piece is placed in a test chamber. The test chamber is then evacuated to an absolute pressure of about 10 – 20 mbar. SF6 escaping from the specimen and thus entering the test chamber is drawn into the system’s detection chamber via the vacuum module.
