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.

Future-proofed for flexibility

Anticipating future SF₆ regulations, this dual gas equipment is available with either SF₆ or g³ gas. Because of its identical foundational design, transmission system operators can implement the SF₆ version today and easily make the switch to our g³ solution later to decarbonize their substations.

Reduced carbon footprint

The B105g SF₆-free GIS is part of our portfolio of solutions designed to accelerate the decarbonization of the grid. The B105g is available in a fully SF₆ -free version using our g³ technology, one of the company’s alternative technologies to SF₆, allowing for an approximately 99% CO2eq reduction of the gas contribution to global warming. While it has the same dimensions, performance and ratings as SF₆, the B105g advanced sealing system and improved tightness reveal a significantly lower carbon footprint compared to its SF₆ equivalent.

Low Cost of Land and Civil Works

One of the most compact 245 kV GIS, complete bays including digital devices and the low voltage control cabinet are assembled, wired, factory-tested and shipped. The standardized digital native B105 GIS is mechanically engineered to reach the accuracy required by advanced monitoring and control solutions. It can be fitted with digital power sensing using low-power instrument transformers. As a result, our digital native B105 allows for an easier and faster supply chain process, shorten delivery, erection and commissioning times.
