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.
