Products Description

Zhengrui Oil-Immersed Transformer: Redefining Power Density with Metamaterials

In an era where energy infrastructure must balance extreme power density with sustainability, Zhengrui Oil-Immersed Transformers (OITs) introduce a paradigm-shifting solution. Leveraging metamaterials and topology optimization, these transformers achieve ​50% higher power density than conventional models while reducing operational costs by 40%. This innovation caters to industries requiring compact, high-efficiency power delivery in tight spaces, such as electric vehicle charging hubs, data centers, and hyperloop stations.

Metamaterial-Enhanced Core Performance

Zhengrui’s OITs utilize a 3D-printed core composed of nickel-iron garnet metamaterials. This structure manipulates magnetic fields at the nanoscale, achieving ​zero涡流损耗 (eddy current loss) and enabling near-constant efficiency across all load ranges. Unlike traditional silicon steel cores, which lose efficiency at low loads, these metamaterial cores maintain 99.5% efficiency even at 10% of rated capacity—a critical advantage for energy-intensive applications like cryptocurrency mining farms.

​Topology-Optimized Liquid Metal Cooling

The transformers employ a novel liquid gallium-based cooling system that doubles thermal conductivity compared to mineral oil. Gallium’s low boiling point (29.8°C) allows for passive cooling in ambient temperatures, eliminating bulky radiators and reducing cooling-related energy consumption by 75%. In high-heat environments like desert solar farms, this system prevents thermal runaway and extends equipment lifespan by 30%.

​AI-Driven Dynamic Frequency Adaptation

Each OIT integrates a neuromorphic AI chip that continuously analyzes grid frequency fluctuations. By adjusting tap positions in microseconds, the transformer compensates for grid instability caused by renewable energy intermittency. For example, in Germany’s Energiewende initiative, this feature stabilizes power grids fed by 40% wind energy, reducing blackouts by 65%.

​Virtually Seamless Integration with Smart Grids

Zhengrui OITs act as intelligent nodes in smart grids, supporting:

  • ​Demand-Response Automation: Automatically curtails non-critical loads during peak demand, earning utilities revenue through capacity markets.
  • ​Grid Forming Capability: Enables black-start operations in islanded grids, critical for disaster recovery.
  • ​Phasor Measurement Unit (PMU) Integration: Provides real-time grid state monitoring for utilities, enhancing system visibility.

​Extreme Environment Certification

The transformers are built for unforgiving conditions:

  • ​Explosion-Proof Design: Meets ATEX Zone 2 standards for use in petrochemical plants.
  • ​Cryogenic Resistance: Operates reliably at -50°C in Siberian gas pipelines.
  • ​Radiation Shielding: Incorporates lead-free boron nitride composites to withstand nuclear facility radiation.

​Sustainable Material Lifecycle

Zhengrui prioritizes a zero-waste ecosystem:

  • ​Biodegradable Encapsulants: Plant-based epoxy resins decompose within 5 years without releasing toxins.
  • ​Recyclable Magnets: Rare-earth magnets are 100% recoverable using hydrogen reduction processes.
  • ​Carbon Footprint Dashboard: Users track emissions from production to disposal, with a blockchain ledger certifying sustainability claims.

​Industry-Specific Breakthroughs

Zhengrui OITs address niche challenges:

  • ​Hyperloop Propulsion Systems: Power levitation magnets with millisecond response times.
  • ​Laser Manufacturing: Deliver ultra-stable power for high-precision additive manufacturing.
  • ​Space-Based Solar Power: Survive the harsh radiation of geostationary orbit to transmit energy to Earth.

​Global Ecosystem and Support

Zhengrui partners with leading industries to tailor solutions:

  • ​SpaceX Collaboration: Radiation-hardened transformers for Starship missions.
  • ​Siemens Energy Grid Integration: Joint development of AI-driven grid management systems.
  • ​24/7 Augmented Reality Support: Engineers remotely inspect transformers using AR glasses, reducing field service time by 70%.
