n an era demanding sustainable infrastructure and digital transformation, Hertzman (Hangzhou) Power Technology Co., Ltd. delivers next-generation power distribution systems that prioritize safety, reliability, and environmental stewardship. As an innovator in switchgear, protection devices, and energy management, we empower utilities, industries, and smart cities worldwide.
Why Hertzman Stands Apart?
- SF6-Free Leadership:
- R-AIR Switchgear: Pioneering 12kV air-insulated technology using clean dry air instead of potent greenhouse gas SF6. Certified IP67 gas compartment and visual isolation breaks ensure safety.
- NXGREEN & SOGEAR: Fixed eco-sealed air-insulated & solid-insulated RMUs minimizing carbon footprint without compromising performance (20kA-25kA breaking capacity).
- Extreme Resilience:
- Internal Arc Protection (IAC): NXSAFE/NXGEAR cabinets withstand 31.5kA/1s arc faults (IEC 62271-200), protecting personnel and critical assets.
- Military-Grade Security: Containerized ESS units feature IP54 rating, 10-level seismic resilience, 2-hour fire resistance, and -30°C to 55°C operability.
- Intelligence Embedded:
- VHZ4i Smart Breakers: Real-time mechanical/circuit monitoring via integrated sensors for predictive maintenance.
- DAVIDCLOUD Ecosystem: AI-driven cloud platform for predictive analytics, energy optimization, and remote O&M across all assets.
- Hyper-Efficiency:
- NXATS Dual-Power Systems: <100ms transfer for critical loads (hospitals/data centers) via patented mechanical interlocks.
- EXAPF+EXVAR: Active harmonic filtering + dynamic compensation reduce losses by 15-30% and ensure THDi <5%.
