IEC gas insulated switchgear ZX2 AirPlus

Eco-efficient gas-insulated switchgear for single or double busbar applications – with the new AirPlus™ insulation gas

The ZX2 AirPlus switchgear design is based on the existing ZX2 portfolio, offering a climate-friendly alternative to end users with a green focus - keeping the same known footprint, safety and reliability. As ABB‘s top-line product, ZX2 primary distribution switchgear is especially suited for demanding applications in single and double busbar configurations in electric power distribution networks.

With AirPlus the global warming potential of the insulation gas is reduced to less than 1 - a reduction of more than 99.99% compared to SF6.

The new AirPlus insulation gas is available in a proven, safe and reliable switchgear design. Without increasing the filling pressure or adding solid-insulation, AirPlus is available in the same compact switchgear dimensions as the already established ZX2. Due to switching inside vacuum bottles, also with AirPlus the gas properties are constant over the complete switchgear lifetime, which makes the medium-voltage gas compartments maintenance-free. 

AirPlus is an alternative to SF6 and not a replacement, you can freely choose the preferred technology: filled with SF6 or 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. This ZX2 is delivered with SF6, but it is fully compatible and tested with AirPlus for a seamless upgrade in the future.

ZX2 AirPlus is currently available in selected European markets. The AirPlus portfolio will be step-wise extended.
