Brunstock is proud to offer electric substation switchgear that is free from greenhouse gases. Our secondary ring main units (RMU) are available in 12kV to 40.5kV, 1250A 31.5kA.
12kV
The BGS-12 (Brunstock Gas-insulated Secondary switchgear), rated in 12kV, adopts vacuum switching and SF6-free sealing technology, seals its main circuit/high-voltage components in the gas tank, is suitable for operation under harsh environmental conditions. This includes operation in dusty environments, high humidity, saline air and even at a high altitude.
The product has a standard unit width of 450mm and a depth of 800mm. Its compact footprint makes it a flexible solution which can be widely applied in all kinds of kiosks, including in renewable wind/solar farms, utilities, airports and railways.

40.5kV
BGS-40.5 is a medium voltage gas insulated switchboard up to 40.5kV, 1250A, 31.5kA, 4s. It is used in secondary power distribution and is designed for customised application of switchgear in:
- Compact secondary substations
- Industrial applications
- Wind and solar power plants
- Hotels, shopping centres, office buildings, business centres etc.
Why is SF6-free switchgear important?
Our SF6-free ring main unit is switchgear that does not use sulfur hexafluoride (SF6) gas as the insulating and interrupting medium. It is the next step in moving our industry into the cleaner, greener future people who care about the environment envisage. SF6 gas has been widely used in electrical switchgear due to its excellent insulating properties and high dielectric strength. However, SF6 is also a potent greenhouse gas with a high global warming potential, and its use has raised environmental concerns.
Brunstock’s SF6-free switchgear utilises alternative technologies for insulation and arc interruption, aiming to eliminate the environmental impact associated with SF6 gas. Brunstock Electric has developed a gas-insulated switchgear (GIS) product that utilises dry air as an alternative gas to sulfur hexafluoride. The lower risk to the environment is due to a lower global warming potential compared to SF6. This will contribute to your ability to meet your project, client or organisation’s sustainability targets.
SF6-free switchgear is a significant technological advancement in the electrical industry, aligning with global efforts to mitigate climate change and reduce greenhouse gas emissions. While SF6 remains prevalent in many existing installations, the transition to SF6-free switchgear is accelerating as regulations tighten and environmental considerations become increasingly important.
