CLEAN AIR COMBINED TRANSFORMER
420 kV
Combined Voltage Transformers, utilizing Clean Air as insulation medium, provide accurate and reliable voltage transformation, (measurement), merging proven safety with eco-friendliness.
BENEFITS
- It uses environmentally friendly air instead of mineral oil or SF6
- Superior Internal arc behaviour: Fully explosion-proof, by IEC 61869-1 Class II, verified in tests
- Clean Air does not cause or spread fire under any circumstances
CHARACTERISTICS
- For voltage levels up to 420 kV
- Clean air as insulation medium
- Fully IEC / IEEE and IEEE seismic level “High” compliant
- Suitable for low-temperature applications at -50°C and below
SUSTAINABILITY
Regenera™ is our holistic approach to protecting ecosystems, fostering environmental harmony and promoting a circular economy.
MAIN FEATURES
The sustainable pure air solution
Clean Air
Like breathing air, the insulator consists of 20% oxygen and 80% nitrogen. The purity is higher and the water content is lower – the most sustainable insulating material for high-voltage devices.
Environmental
The Clean Air Combined Transformer insulation has a global warming potential (GWP) and an ozone depletion potential (ODP) of 0 and ensures CO2 savings of 88% over its entire service life.
Proven design
The design is based on the reliable SF6 devices, that have been in use for 50 years and of which over 100,000 have been in service.
Enhanced operational safety
Superior arc behaviour, absolutely explosion-proof, in accordance with IEC 61869-1 Class II and proven in tests. The safest isolator technology on the market, as pure air neither triggers nor spreads fire.
Maintenance
Maintenance-free and therefore cost - and time - saving over a service life of more than 30 years.
Technical/finance Advantages
There is no need to document or report leaks, as Clean Air is not subject to the F-Gas Regulation. It does not require specialised personnel and does not cost extra to dispose of.
