Our services

From the first enquiry to the commissioned transformer: selection, options, delivery across the EU and documentation for the grid operator.

// Installation

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.

Transformer maintenance service

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.

Custom transformer solutions
// Rental

Delivery from European stock

Standard PNACHO ratings are held in stock in Europe and ship within days – no customs, no surprises.

What we offer:
  • 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.

Tell us the delivery address and we confirm the date with the quote.

// Consulting

Choose the right transformer with an engineer.

Rating, voltage ratio, vector group, losses and options – we help you get them right the first time.

Our consulting services include:
  • 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.

  • One contact: One engineer follows your project from enquiry to commissioning.

Quotes are ready within 24 hours.
