When Siberian winds sweep across the land with temperatures plunging to –40°C, pushing many systems to the brink of shutdown, twelve EvoTec 350 kW / 400 V TD short-shaft generators continue to deliver 24/7 uninterrupted power to a data center located near the Arctic Circle.
Under sustained extreme cold ranging from –20°C to –40°C, power systems face multiple severe challenges:
❄ Insulation embrittlement and cracking, posing direct risks to electrical safety;
❄ Thermal contraction of metals and components, significantly reducing mechanical reliability;
❄ Highly dynamic data center loads, imposing near-critical requirements on voltage and frequency stability.
To address these challenges, EvoTec’s purpose-built 350 kW / 400 V TD short-shaft generator delivers robust performance through multiple cold-resistance technologies:
⚙ Ultra-Low-Temperature Adaptive Insulation System
Specially engineered flexible insulation materials retain elasticity and adhesion even at –40°C, effectively eliminating inter-turn short-circuit risks and significantly extending insulation service life.
⚙ Electromagnetic Design Optimized for Extreme Cold
The electromagnetic system is optimized based on the low-temperature magnetic characteristics of silicon steel, limiting iron-loss increase to below 5% under extreme cold. This ensures a flat efficiency
curve and high efficiency from cold start through full-load operation.
⚙ High-Reliability Low-Temperature Structural Integration
The compact short-shaft design increases rotor rotational inertia, suppressing vibration and resonance risks. An integrated AC exciter provides a more rigid structure with lower losses, enabling quiet, stable,
and reliable operation in ultra-cold environments.
From Antarctic research stations to Arctic Circle data centers, EvoTec has repeatedly proven the exceptional environmental adaptability of its generators through real-world extreme-condition deployments. Leveraging its
Extreme-Environment Power Adaptation System technology platform, EvoTec delivers highly customized power solutions for high-altitude, ultra-cold, high-temperature, and high-humidity applications worldwide—demonstrating the reliability of Chinese engineering on a global stage.
Looking ahead, EvoTec will continue advancing generator technology through innovation, delivering smarter, more efficient, and more reliable power solutions to support global digital infrastructure—ensuring stable power remains a guiding beacon even in the world’s harshest environments.
