Medium Voltage (MV) switchgear is a critical component of electrical distribution systems. Urbanisation and economic growth continue to drive infrastructure expansion. A significant portion of the MV equipment deployed in electrical networks contains SF6 gas, which has a high global warming potential (GWP)


What is SF6-free medium voltage switchgear innovation?

Our newest innovations in SF6-free medium voltage switchgear are using pure air and solid insulation and vacuum breaking technology for the most sustainable solutions.


How does SF6-free MV switchgear meet market requirements?

They are designed to cater to all major power distribution applications in primary and secondary energy networks, including distributed renewable generation up to 36kV.


Is SF6-free MV switchgear IoT-connected?

IoT-embedded sensors and connectivity provide the latest digital experience and a pathway to predictive maintenance and cost reduction.


What are the benefits of SF6-free MV?

Switching to air and digital MV switchgear delivers boosted efficiency, reduced carbon footprint (CO2e) and compliance with any upcoming regulations on SF6 and F-gases.

Air-Insulated IoT Switchgear

Gas-insulated primary distribution switchgear offers high-performance functionality with compact installation footprints, unmatched by other designs. Rated up to 52kV, our well-known and proven designs are connected with the latest devices and features like arc flash protection and condition monitoring sensors to help you maximize the life of your switchboard.

Air-Insulated Switchgear (AIS) is a key component of secondary medium-voltage electrical distribution networks operating at 12 kV to 36 kV.


What are the key benefits of AIS switchgear?

  • With air insulation between live components, they offer peace of mind by simplifying the design and maintenance. Components are easily accessible for quick and efficient maintenance.
  • Modular design allows easy customisation, expansion, and integration of additional units.
  • Safety and reliability provided by design with high safety standards, incl. arc resistance and advanced protection devices, to protect operators and equipment from overvoltage and short circuits.

Where is AIS switchgear used?

It perfectly fits various applications, from industrial facilities, large and commercial buildings, hospitals, airports to electrical distribution networks.


What are its advanced digital capabilities?

New IoT-connected features enable predictive maintenance to maximise efficiency and minimise downtime.

Whether electric companies, windfarms or private networks, secondary switchgear makes the connection to our homes and businesses to bring us reliable power everyday. Space is often at a premium, meaning that our range of secondary gas insulated switchgear designs are the perfect fit. Our ring main units (RMUs) are becoming IoT connected and smart to bring extra benefits and everyday simplicity.
