Welcome to the Future of Wind Power: 72.5 kV Gas-Insulated Substations

The offshore wind market is seeing significant growth with more powerful windfarms gradually moving into deeper waters, much farther from shore. Our 72.5 kV GIS type F35 can double the voltage as compared with medium-voltage technologies. Energy from a wider area can be handled by a single platform using 66 kV alternating current (AC), reducing energy losses.

GE Vernova provides GIS solutions from 50 kV to 800 kV, along with smart devices to maximize switchgear and network operation. The portfolio includes a full range of SF₆ GIS as well as g³ (SF₆-free) GIS at 145 kV and 420 kV voltage levels for utilities and industries worldwide.

The B105g SF₆-free GIS is part of GRiDEA, our portfolio of solutions designed to accelerate the decarbonization of the grid. Its design is grounded in more than 50 years of field experience in SF₆ and eight years in g³ technology as insulating and switching medium. Our B105 Dual Gas GIS bay – compatible with either SF₆ or g³ gas – meets the challenges of 245 kV networks for onshore and offshore power generation and transmission, as well as energy-intensive industry applications.
