What Is a Load Break Switch? - Electrical Engineering Portal· In our system we have some old pad mounted S&C live front switch gear the manufacturer say that a load buster tool must be used to break load,in the past we always broke load if it was under 15amps and that could be at different high voltages ex:4kv,8kv, 13kv and these are normally single phase transformer.Our dilemma now is that workers are refusing to break load with this solid blade …

PG&E to Use SF6-Free High-Voltage Products From Siemens ... has received orders from its customer Pacific Gas and Electric (PG&E) to supply SF6-free dead-tank circuit breakers and gas-insulated switchgear (GIS). They are destined for California's 115-kV high-voltage grid. The orders comprise dead-tank circuit-breakers for 72.5 kV and 115 kV as well as GIS for 115 kV.
Myth About SF6 Gas In Electrical Equipment· 3. Is SF6 harmful for the environment? It has no ecotoxic potential, it does not deplete ozone. Due to its high global warming potential of 22.200 (*) it may contribute to the man made greenhouse-effect, if it is released into the atmosphere. However in electrical switchgear the SF6 gas is always used in gas-tight compartments, greatly minimising leakage.
