Gas-insulated substation F35g

for high-voltage transformerscompact

GE's F35g is a g3-gas-insulated substation up to 145 kV, up to 3,150 A and 40 kA using GE’s revolutionary g3 gas mixture as an insulating and switching alternative to SF6. The F35g g3-GIS is designed to deliver the same performances and reliability features as today’s existing SF6 switchgear, without SF6's environmental impacts. Compared to SF6 switchgear, they feature: •Same dimensions and footprint, no drastic addition of raw material such as aluminum compared with other SF6 alternatives •Same technical performance •Same safety level •Same reliability feature Key Characteristics •A drastically reduced impact of gas releases to atmosphere (99% vs. SF6) •The lowest environmental impact during the whole life cycle: •Impact on climate change: 72% reduction, •Best-in-class Life Cycle Assessment (LCA) considering all environmental aspects from manufacturing to end-of-life The F35 is a compact and accessible GIS solution, with a bay footprint below the market average. Up to 2 bays are assembled together, wired, tested and shipped enabling shorter site works. GE’s F35g is the first SF6-free g3-gas-insulated substation up to 145 kV to complete ENA assessment in the UK.
