Sustainability moved to the next level: SGB SMIT Group successfully tested 1st transformer in Germany with Nynas NYTRO® BIO 300X
Together we have now reached the next level of more sustainable insulating liquids: NYTRO® BIO 300X is a true innovation that has now been fully tested and approved by Starkstrom- Gerätebau GmbH in Regensburg (Headquarter of SGB-SMIT Group), fulfilling, and even exceeding the requirements of the transformer operator, the German utility Westnetz.
The 80 MVA ONAF 115/21 kV transformer manufactured in Regensburg successfully passed the complete sequence of factory acceptance tests. This means all routine and type tests, including lightning impulse and induced over-voltage withstand test, were carried out and the transformer successfully performed in all aspects. In addition, a more stringent and accurate temperature rise test was performed, demonstrating the enhanced cooling potential of NYTRO® BIO 300X. This allowed to validate the SGB-SMIT technology solution utilized for the thermal simulations including detailed modelling & thorough data analysis.
SGB-SMIT Group and Nynas recognize that with the introduction of NYTRO® BIO 300X a unique combination between performance and sustainability is possible. In this specific transformer design, which was based on GTL insulating fluids, NYTRO® BIO 300X was used, after performing several verifications, without requiring any special adaptation.
In addition to being recognised for its ultra-low viscosity, allowing transformers and reactors to operate with better cooling, NYTRO® BIO 300X has also received the US Department of Agriculture’s (USDA) Certified Biobased Product label.Read more about NYTRO® BIO 300X is awarded USDA certification for biobased products
Nynas’ new innovative insulating liquid NYTRO® BIO 300X has been successfully delivered to and tested in a transformer serving electricity customers in Gothenburg, Sweden. The city’s utility company Göteborg Energi opted to use the bio-based and biodegradable insulating liquid in a transformer located in a sensitive water protection area.Read more about NYTRO® BIO 300X fulfilling promises in Gothenburg, Sweden
