Engineered for Extreme Reliability: Hertzman’s Power Systems for Mission-Critical Infrastructure​

When Failure Is Not an Option: Cutting-Edge Solutions for Hospitals, Data Centers & Industrial Sites

For environments where power continuity is non-negotiable, Hertzman (Hangzhou) Power Technology Co., Ltd. designs uncompromising electrical systems trusted by critical facilities across 15+ countries. Combining military-grade resilience with smart grid intelligence, we protect lives, data, and productivity where disruption carries catastrophic costs.

Core Technologies for Zero-Downtime Operations

1. Ultra-Fast Fault Protection

• VHZ4M Rapid Circuit Breakers: 15ms opening time (including arc extinction), 30kA fault clearance in <40ms. Ideal for semiconductor fabs and ICU backup power.

• NXATS Dual-Source Systems: Sub-second transfer (<300ms) with COGEAR mechanical interlocks – no accidental paralleling.

2. Space-Optimized Substations

• NXGIS-40.5 Gas Insulated Switchgear: 60% smaller footprint vs. air-insulated gear. Sealed SF6 compartments for polluted/coastal environments (IP67).

• PRESUB/U Underground Prefabricated Substations: Flood-resistant up to 72 hours. Deploys in 3 days for urban infill projects.

3. Smart Defense Systems

• DAVIDCLOUD Predictive Platform: AI-driven failure alerts for critical assets:
  • Thermal imaging of bus joints
  • SF6 density/pressure trends
  • Contact erosion forecasting (±5% accuracy)

• EXAPF Active Filters: Maintain THD <3% in data center UPS systems.

Industry-Specific Validation

Global Project Spotlight

• Shanghai Data Hub (Phase 3): 128 NXSAFE-12 panels + DAVIDCLOUD monitoring – 0.99989 availability since 2021.
• Bangkok Metro Purple Line: 47 NXGIS-40.5 substations – zero forced outages in tropical monsoon conditions.
• Singapore National University Hospital: NXRING-ATS dual-power – seamless transfers during 2022 grid fluctuations.
