Engineering the Future: Hertzman’s Patented Power Technologies Driving Global Grid Modernization

Hertzman (Hangzhou) Power Technology Co., Ltd. redefines electrical infrastructure through patented R&D and rigorous global compliance. With 60+ inventions protecting mission-critical innovations—from SF6-free insulation to predictive grid intelligence—we deliver future-proof solutions for utilities and industries operating under IEC, GB, ANSI, and GOST regimes.

Breakthrough Technologies

1. Gas-Free Insulation (Patents CN202111610202.4/CN202111610216.6)
   R-AIR series switchgear replaces SF6 with dry air achieving:

   • IP67-rated sealed chambers
   • Visual isolation breaks
   • Full 20kA/25kA fault interruption
     Eliminating 23,500x GWP emissions per unit.

2. Dual-Power Security (Patent CN202010732834.7)
   NXATS systems feature:

   • Mechanical spindle interlock (fail-safe)
   • Sub-100ms transfer (hot/cold standby)
   • 31.5kA short-circuit withstand

3. Solid Insulation 3.0 (SOGEAR Platform)
   Epoxy-resin encapsulation enables:

   • Salt-fog/Coastal operation (IP67)
   • -40°C to 65°C stability
   • 30-year pollution resistance

4. DAVIDCLOUD Predictive Analytics
   AI-driven platform monitoring:

   • VHZ4i breaker wear (travel/time analysis)
   • NXGIS gas density trends
   • EXAPF harmonic resonance risks
