Eco-efficient Switchgear

– ABB’s family of eco-efficient gases consists of components of air (O2, N2, CO2) and C5-Fluoroketones.

– AirPlus™ is Hitachi ABB Power Grids’ family of eco-efficient gas mixtures as an alternative to SF6 for high-voltage (HV) products

– LTA (Live tank breaker) technology is using CO2/O2 mixture

High voltage switchgear and AirPlus™

For decades

SF6 gas has been used extensively in switchgear

due to its excellent dielectric insulation and current

interruption properties. However, it is a

greenhouse gas that requires careful handling
