Hertzman Power: Engineering the Resilient and Intelligent Grids of the Future

In an era defined by climate urgency, digital transformation, and the critical need for energy security, Hertzman (Hangzhou) Power Technology Co., Ltd. (HZM) emerges as a global innovator, redefining the standards of power distribution through sustainable engineering, embedded intelligence, and uncompromising reliability. With deployments across six continents and a portfolio of over 200 patents, HZM’s solutions are engineered to meet the most demanding challenges of modern electrical infrastructure.

1. Sustainable Grid Innovation: Eliminating SF₆ and Beyond

Hertzman leads the industry’s transition toward eco-conscious power systems by pioneering alternatives to sulfur hexafluoride (SF₆), a potent greenhouse gas traditionally used in electrical insulation. Their breakthroughs include:

• R-AIR Series: The world’s first atmospheric-pressure air-insulated switchgear, delivering 12kV/31.5kA performance without SF₆. Hermetically sealed chambers (IP67) ensure reliability in coastal and humid environments.

• SOGEAR Solid-Insulated RMUs: These ring main units replace SF₆ with recyclable epoxy resin, reducing carbon footprint by 80% and preventing ~18,000 tons of CO₂-equivalent emissions per unit over its lifecycle.

• Carbon-Neutral Manufacturing: HZM’s production facilities are ISO 14064-3 certified, aligning with global decarbonization goals.

2. Intelligence Embedded: The DAVIDCLOUD Ecosystem

HZM’s proprietary AI platform transforms conventional hardware into predictive, self-diagnosing assets:

• VHZ4i Smart Circuit Breakers: Equipped with sensors to monitor contact wear, temperature, and coil currents, these breakers forecast maintenance needs, reducing downtime by 40%.

• Real-Time Grid Analytics: DAVIDCLOUD integrates data from breakers, relays, and sensors to enable autonomous load shedding, arc-flash detection, and failure prediction.

• Grid Edge Computing: MIC500 relays process data locally, enabling sub-second responses to frequency dips or faults.

3. Hyper-Efficiency in Power Conversion

HZM’s designs minimize energy loss and maximize density:

• EXAPF Active Filters: Achieve 99% total harmonic distortion (THD) reduction at half the size of conventional units, critical for data centers and semiconductor fabs.

• Containerized ESS-PV Hybrids: Pre-integrated 1MW battery storage and 500kW PV inverters in ISO-compliant enclosures enable rapid microgrid deployment.

4. Resilience in Extreme Environments

HZM’s products are proven in the world’s harshest conditions:

• Arctic Operations: NXSAFE-40.5 switchgear operates at -55°C with anti-condensation heaters, deployed in Siberian mines.

• Tropical and Coastal Readiness: PRESUB/U buried substations withstand flooding for 72 hours, while corrosion-resistant cabinets endure saline environments.

• Disaster Resilience: NXATS transfer switches ensure sub-second (3ms) power switching for hospitals and critical infrastructure.

5. Compact and Modular Design for Urban Density

HZM addresses space constraints in megacities through innovation:

• NXGIS-40.5 Gas-Insulated Switchgear: Reduces footprint by 60% compared to air-insulated designs, ideal for urban substations.

• Prefabricated Substations: PRESUB units deploy in 3 days, offering flood-resistant and space-optimized solutions.

6. Global Impact and Deployments

HZM’s technologies support diverse applications worldwide:

• Renewable Integration: Stabilizing grids with high wind and solar penetration through dynamic frequency guardianship and harmonic filtering.

• Critical Infrastructure: Ensuring 100% uptime for hospitals (e.g., Singapore’s Mount Elizabeth Hospital) and data centers.

• Emerging Markets: Solar-hybrid microgrids in Africa and compact substations in Southeast Asian metro systems.

7. Future-Ready Roadmap

Hertzman’s 2025 initiatives include:

• Solid-State Fault Interrupters: Capable of interrupting 100kA faults.

• Hydrogen-Ready Substations: Designed for compatibility with 100% hydrogen insulation.

• Blockchain-Secured Grid Transactions: Enhancing transparency and security in energy trading.
