dilo GCB SF6-alternative gases units

Translate this pageMixed gas filling of sf6 and N 2 gives a somewhat deteriorated thermal breaking capacity as well as a slightly deteriorated dielectric breaking capacity compared with only sf6 gas gas filling. Mixed gas filling with nitrogen often results in a reduction of breaking capacity, e.g., a rated breaking current of 40 kA is reduced one step to 31.5 kA.
