G SERIES circuit breakers
SF6 insulated MV load break switch

The G type Load Break Switch disconnector external housing is realized in cast insulating resin with one sealing for SF6 gas in the front area. The load break switch is arc proof tested.

The overpressure valve is integrated in the structure for a safety arc proof functionality. Dielectric field distribution and leakages current between incoming and outgoing terminals are controlled by large creepage distances bushing and by internal earth grid to provide safety conditions of service and personnel. The Load Break Switch spring mechanism can be motorized; the interruptions and the insulation thanks to SF6 gas are indipendent from site conditions.
