Secure Supply of Transformer Fluids in Uncertain Times

Recent disruptions to refinery capacities and global shipping routes have exposed the vulnerability of long and highly concentrated supply chains for critical transformer fluids. From our European base, Nynas offers energy utilities and transformer manufacturers a reliable supply, in-depth application knowledge, and high-performance products with excellent sustainability characteristics.

Global turbulence and geopolitical conflicts are increasingly having a direct impact on the supply of critical oil products and industrial raw materials. Recent disruptions have highlighted the vulnerability of highly concentrated supply chains – including specialized transformer fluids used in power supply infrastructure.

NYTRO RR 900X

• Easily suitable for the most demanding electrical applications
• Maintains the dielectric behavior of conventional naphthenic fluids
• Equal, if not superior, to other high-performance transformer oils
• Meets the IEC 60296 (2020) TYPE A standard
• Reduction of greenhouse gas emissions by at least 70% over the life cycle

NYTRO BIO 300X

• Renewable hydrocarbon
• Biodegradable
• Ultra-low viscosity and excellent heat transfer
• Significantly lower transmission losses compared to all oils known on the market
• Top-class oxidation stability
• Meets and exceeds the IEC 60296 standard

"These challenges – along with increasing demands for sustainability, life-cycle emissions, and regulatory compliance – mean that transformer manufacturers and energy utilities must evaluate resilient alternatives," says Thomas Norrby, Technical Manager Transformer Oils at Nynas and Adjunct Professor at the KTH Royal Institute of Technology in Stockholm.

As a leading European manufacturer of transformer fluids, Nynas is ideally positioned to support energy utilities and transformer manufacturers with reliable alternatives that help strengthen supply chain resilience.

"Our regional production close to European customers reduces dependence on intercontinental shipping routes," emphasizes Annika Girod, Marketing Director at Nynas. "Shorter transport routes, local production, and decades of specialist expertise offer our customers greater predictability in an increasingly uncertain global market."

At the same time, products such as NYTRO® RR 900X and NYTRO BIO 300X also support broader sustainability goals. By combining high technical performance with circular or renewable raw materials, these solutions can help energy utilities reduce life-cycle emissions while maintaining reliability and operational safety in critical power supply infrastructure.

"As a bio-based hydrocarbon fluid, NYTRO BIO 300X represents a valuable alternative in times of supply disruptions," concludes Thomas Norrby.
