NYTRO® BIO 300X successfully delivered and tested by Končar D&ST
Nynas recently completed a delivery of its new bio-based transformer fluid NYTRO® BIO 300X to Končar Distribution & Special Transformers in Croatia.
Končar Distribution & Special Transformers
With 90 years of tradition in the production of electrotechnical products, Končar Distribution & Special Transformers Inc. (Končar D&ST), based in Zagreb, Croatia, is a regional leader in the production of distribution, medium power and special transformers up to 160 MVA and 170 kV.
A 40 MVA, 145 kV transformer was filled with the sustainable insulating liquid NYTRO BIO 300X and tested by Končar’s technical team in Zagreb, Croatia.
“The thermal and dielectric tests on the transformer filled with NYTRO BIO 300X were completed successfully, and the unit is considered fully functional,” said Ivanka Radić, responsible for transformer oil at Končar D&ST. “As expected, the DGA results before and after the IEC 60076-2 standard temperature rise test were perfectly acceptable.”
The ultra-low viscosity of NYTRO BIO 300X also means that it provides enhanced cooling in the transformer.
“The results of the factory acceptance tests were highly satisfying, with the transformer behaving as expected. Oil temperatures were an impressive 10 degrees lower in the unit than when a synthetic ester insulating liquid was used,” said Vedran Maljković, Quality control manager at Končar D&ST.
A regional leader in the production of distribution, medium power and special transformers, for Končar D&ST it is vital to be at the forefront of technical innovation and sustainable development.
“This project and partnership with Nynas to introduce more sustainable insulating liquids is a natural step for us. We look forward to filling more transformers with NYTRO BIO 300X and continuing to take steps in a green direction with the support of Nynas,” said Vanja Burul, Member of the Management Board at Končar D&ST.
The technical and commercial teams at Končar D&ST and Nynas worked closely together to achieve the successful outcome of the delivery and the subsequent tests. In connection with their conclusion, Nynas presented Končar D&ST with a certificate as the first to implement a 40MVA 145 kV transformer filled with NYTRO BIO 300X.
“We are very proud to have been entrusted with this project by Končar D&ST, allowing us to showcase to them and the whole electrical industry the advantages of this fully renewable, bio-based hydrocarbon liquid that is now available to the market,” said Thomas Feischl, Sales Executive Nynas. “In addition to meeting and exceeding the IEC 60296 ed 5 (2020) specification, the product is readily biodegradable, fully bio-based and has ultra-low viscosity.”
