The ZX2 AirPlus range features an insulation gas mixture that ABB said is the first and only new ‘green’ alternative to traditional sulphur hexafluoride, or SF6, a greenhouse gas. The company added that its gas boasts a global warming potential (GWP) of less than one, a reduction of almost 100 per cent compared to SF6.
The company said it aims to offer sustainable switchgear alternatives as China looks to fulfil its climate target of reducing CO2 emissions by 54 per cent from 2010 levels by 2030.
The new switchgear range, which is designed for primary power distribution, was released earlier this year in Europe with IEC ratings up to 36 kV. According to ABB, it is now also available in Chinese GB ratings up to 40.5 kV rated voltage and 2000 A rated current.
Alessandro Palin, managing director of ABB’s Medium Voltage business, said: “AirPlus is a groundbreaking gas and ABB is proud to have been the first in the world to offer a viable, green alternative to the highly potent SF6. It sits perfectly with the ZX0 Air switchgear, which uses dry air as insulation gas and has been developed specifically to suit the Chinese 12 kV market.
“It’s in all our interests that we embrace and invest in greener technologies to safeguard our planet for future generations,” he added.
