Keynetgrid is a European transformer brand of Wensday Invest Sp. z o.o., based in Poznań, Poland. We design the PNACHO range to European standards, verify every unit before it ships and publish the numbers – losses, impedance, mass, noise – so buyers can compare on facts.
Keynetgrid grew out of years of trading and servicing distribution transformers for utilities, industry and renewable-energy projects. We saw the same problem everywhere: long lead times, unclear pricing and data sheets that hide the numbers that matter.
PNACHO is our answer – two series of Ecodesign Tier 2 transformers, 25 to 2500 kVA, with published data, stock in Europe and a 5-year warranty. Today we deliver to customers in every EU country.
Reliable Tier 2 transformers available to every project in Europe at a fair price – with a warranty, complete documentation and a person who answers the phone.
To become the reference for straightforward transformer supply in Europe: transparent data, transparent prices, short lead times and long-term partnerships with installers, EPC contractors and network operators.
The PNACHO range covers the standard needs of medium-voltage distribution in Europe:
Hermetically sealed oil-immersed transformers 25–2500 kVA, 6.3 / 10 / 21 kV, Dyn11, ONAN – for utilities, industry, compact substations and renewables.
Explore the full PNACHO range by series, rated power and voltage ratio.
0.8 kV low-voltage winding for central photovoltaic inverters, 630–2500 kVA, oil-immersed or cast-resin.
