ETRA SUBSTATION Oil-filled power transformer

Description

Kolektor ETRA supplies oil-filled power transformers up to 500 MVA and voltage up to 420 kVA.

For step-up and step-down power transformers, as well as for production transformers in electrical substations, 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 dimensioning of conductors and insulating materials to cope with production peaks linked to hydroelectric turbines, and the effects of overheating linked in particular to sunshine or the use of transformers in confined areas.

Low levels of no-load and on-load losses require the use of the very best materials and technological know-how, which KOLEKTOR ETRA^® possesses, enabling us to offer you the transformer that will cost you the least throughout its life cycle, whether on-load or off-load. The noise levels achieved by our transformers are low enough to considerably reduce the cost of building anti-noise devices.

For substation applications, we can offer transformers equipped with ONAN, ONAF, ODAF, OFAF, ODWF or OFWF cooling systems.

Finally, thanks to our EDF-ISATION program 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, including factory project management, and site project management in France through our subsidiary SONEC^® (see Accessories and Options tab).
