Our services
From the first enquiry to the commissioned transformer: selection, options, delivery across the EU and documentation for the grid operator.
Installation services
End-to-end installation support
Keynetgrid supports the whole installation: site assessment, choice of the right PNACHO configuration, delivery with crane unloading and placement, and coordination with your electrical contractor.
Every transformer is routine-tested before dispatch and arrives with its test report, CE declaration and manual, so commissioning and grid-operator approval go without delays.
Regular maintenance and repair services
PNACHO-O hermetically sealed transformers need no oil maintenance; PNACHO-D cast-resin units need no oil at all. We provide inspection guidelines and spare parts so the transformer performs for more than 30 years.
Within the 5-year warranty and beyond, our engineers help diagnose and resolve issues quickly – remotely or on site – to keep downtime to a minimum.
Custom solutions services
Every network is different. We offer copper windings, other voltage ratios and vector groups, 0.8 kV PV versions, ester oil, enclosures and protection relays – specified to your requirements.
You receive a transformer that matches your specification, with the same published data, routine tests and 5-year warranty as the standard range.
Delivery from European stock
Standard PNACHO ratings are held in stock in Europe and ship within days – no customs, no surprises.
Tell us the delivery address and we confirm the date with the quote.
Delivery and unloading
Transport to any EU country, with crane unloading and placement on request.
Short lead times
Standard ratings ship from stock; other configurations are produced to order with confirmed dates.
Documentation pack
Test report, CE declaration, manual and drawings delivered with every unit – ready for the grid operator.
Choose the right transformer with an engineer.
Rating, voltage ratio, vector group, losses and options – we help you get them right the first time.
Quotes are ready within 24 hours.
Needs analysis
We assess load profile, network voltage, installation site and grid-operator requirements.
Individual solutions
Where the standard range does not fit, we specify copper windings, other ratios, enclosures or special protection.
Loss evaluation (TCO)
We compare total cost of ownership of the options over 20–30 years of service, not just the purchase price.

PNACHO options and special versions
Beyond the standard configurations, PNACHO transformers are available with options for photovoltaic plants, demanding environments and special networks.
- PNACHO
PV transformers 0.8 kV
0.8 kV low-voltage winding matched to central photovoltaic inverters, 630–2500 kVA, oil-immersed or cast-resin.
- PNACHO
Dual-voltage and custom ratios
Dual-voltage HV windings (e.g. 10/21 kV), 0.4 / 0.69 kV low voltage, Dyn5 / Yzn5 and on-load tap changers on request.
- PNACHO
Copper windings and enclosures
Cu/Cu windings, ester oil MIDEL 7131, IP23–IP44 enclosures, anti-vibration pads and bird guards for demanding sites.
