ABB expands eco-efficient medium-voltage portfolio

ABB has introduced UniSec with AirPlus™ – a compact and completely SF6-free medium-voltage switchgear. At this year’s Hanover fair, ABB exhibited the air-insulated switchgear UniSec as a completely SF6-free switchgear solution for networks up to 24 kV. It uses the HySec AirPlus, a multifunction apparatus, combing the functions of circuit breaker, line disconnector and earthing switch all-in-one, which is now available with AirPlus insulation gas.

AirPlus is a groundbreaking climate-friendly gas mixture with a 99.99 per cent lower global warming potential (GWP) compared to SF6. AirPlus is the first ‘green’ alternative gas on the market for medium-voltage switchgear and is part of ABB’s ongoing strategy to develop eco-efficient technologies. AirPlus is a gas mixture based on a fluoroketone molecule and more than 80 per cent dry air.
“ABB is proud to extend the eco-efficient medium-voltage offering of viable alternatives to SF6,” said Alessandro Palin, Managing Director of ABB’s Distribution Solutions business line. “This underlines ABB’s commitment and relentless drive to bring sustainable alternatives to the market and broaden the eco-efficient portfolio to help shape the climate-friendly infrastructure of tomorrow.”

In addition, the ZX2 AirPlus switchgear for single or double busbar applications up to 36 kV (IEC standard) will be displayed. Customers can freely choose the preferred technology: filled with SF6, AirPlus, or as ‘Ready-for-AirPlus’ – the choice for businesses that want to be prepared to switch to the eco-efficient alternative in the future. ZX2 AirPlus is also available in 40.5 kV (GB standard) for the Chinese market.
