For step-up power transformers, as for wind farm production transformers, we pay particular attention to reducing the transformer’s noise level, as well as ensuring very low load and no-load losses. We also consider the sizing of conductors and insulating materials to cope with production peaks associated with hydroelectric turbines, and the effects of overheating associated in particular with sunshine or the use of transformers in confined areas.
Low levels of no-load and on-load losses require the use of the best materials and a great deal of technological know-how, which KOLEKTOR ETRA® has at, enabling us to offer you the transformer that will cost you the least throughout its life cycle, whether it is on-load or no-load. The noise levels achieved for the transformers are low enough to considerably reduce the cost of building anti-noise devices.
For offshore wind farm applications, we can offer transformers equipped with ONAN, ONAF, ODAF, OFAF, ODWF or OFWF cooling systems.
We have numerous references in the North Sea for applications on offshore platforms and deep-sea wind farms. We also have recognised expertise in onshore wind farms and substations for onshore wind farms or photovoltaic fields, with numerous European references, particularly in Germany, the UK, Norway and Sweden, countries which, like France, are renowned for their high standards of quality and technical rigour.
Finally, thanks to our EDF-ISATION programme launched in 2016 with the SANERGRID Group® and our power transformer experts SYNERDIS®, you benefit from service and technical support in French from the sales department to the design office, via plant project management,
