sf6 o2 Leakmate for HV MV

sf6 o2 Leakmate for HV MV

The ban on SF6 in the energy sector lags behind other industries. Historically, that was partly due to a lack of viable alternatives, but that has changed, with several switchgear manufacturers making significant investments in SF6-free solutions across MV and HV, some of which are already successfully deployed.
