Hertzman Power: Engineering the Future of Resilient and Intelligent Power Distribution
2025-09-13 09:54In an era defined by the urgent need for energy resilience, sustainability, and digitalization, Hertzman (Hangzhou) Power Technology Co., Ltd. (HZM) has established itself as a global leader in advanced power distribution solutions
. This Sino-foreign joint venture combines cutting-edge engineering with a deep commitment to environmental stewardship, delivering next-generation electrical infrastructure that powers everything from megacities to critical lifesaving facilities.The Core Pillars of Hertzman's Innovation
Hertzman's product philosophy is built upon three foundational pillars: Extreme Reliability, Embedded Intelligence, and Compact Design
.•
1. Uncompromising Reliability: Hertzman engineers resilience into every product. Their switchgear, such as the NXSAFE Metal-Clad Removable Switchgear, is built with corrosion-resistant, high-strength materials and features patented "Five-Prevention" mechanical interlocks to eliminate critical human errors during operation
. Key to this reliability is their VHZ4 Series of Intelligent Vacuum Circuit Breakers, renowned for a longevity of up to 20,000 mechanical operations and rated for demanding performance (up to 40.5kV, 4000A, 40kA breaking capacity). Furthermore, critical switchgear lines are rigorously tested for internal arc faults (IAC), containing failures to protect both personnel and adjacent equipment, a vital safeguard for operational continuity.•
2. Embedded Intelligence: Hertzman transforms static hardware into predictive, smart grid assets. Their VHZ4i intelligent circuit breakers are equipped with sensors to monitor parameters like contact wear, temperature, and travel characteristics, enabling predictive maintenance
. This data feeds into the DAVIDCLOUD ecosystem, an AI-driven cloud platform that provides real-time remote monitoring, advanced analytics for failure prediction, and optimized energy management across the entire power network. This intelligence allows for a shift from scheduled to condition-based maintenance, drastically reducing downtime and operational costs.•
3. Compact and Sustainable Design: Hertzman leverages innovative insulation technologies to achieve a smaller physical footprint without sacrificing performance. A landmark achievement is their R-AIR Series, the world's first atmospheric-pressure air-insulated switchgear, which eliminates the use of potent SF₆ greenhouse gas while maintaining full performance (12kV/31.5kA)
. Similarly, the SOGEAR Solid-Insulated Ring Main Units (RMUs) use recyclable epoxy resin, reducing the carbon footprint of secondary distribution by 80% compared to traditional SF₆-insulated units. Each deployed SOGEAR unit is estimated to prevent approximately 18,000 tons of CO₂-equivalent emissions over its lifecycle.
A Comprehensive Portfolio for a Diverse World
Hertzman's extensive product range is designed to meet the vast spectrum of modern power distribution needs
:•
Medium Voltage Switchgear: The flagship NXSAFE series (up to 40.5kV) and the ultra-compact, gas-insulated NXGIS-40.5 series, which offers a 60% smaller footprint, cater to primary distribution in substations and large industrial plants
.•
Secondary Distribution RMUs: The NXRING (gas-insulated) and SOGEAR (solid-insulated) Ring Main Units provide reliable and compact switching for feeder automation, ideal for urban networks and commercial complexes
.•
Low Voltage Solutions: The EXSINE Low-Voltage Drawout Switchgear offers modular, arc-flash protected design, while EXT Series Intelligent Air Circuit Breakers and EXAPF Active Harmonic Filters ensure protection and power quality management
.•
Critical Power Continuity: NXATS Medium Voltage and EXATC Low Voltage Automatic Transfer Switches ensure sub-second transfer times (<300ms), providing seamless backup power for hospitals and data centers where failure is not an option
.•
Renewable Integration: Hertzman offers containerized ESS-PV Hybrid systems (1MW battery + 500kW PV inverter) and prefabricated PRESUB substations for rapid microgrid deployment, supporting the global transition to clean energy
.
Proven Performance in Extreme Conditions
Hertzman's equipment is engineered to conquer the world's most challenging environments, ensuring reliability where it matters most
:•
Arctic Operations: NXSAFE-40.5 switchgear with heated condensation control operates reliably in Siberian gold mines at temperatures as low as -55°C
.•
Tropical and Coastal Climates: Hermetically sealed R-AIR switchgear (IP67) prevents moisture ingress in humid and coastal areas, while corrosion-resistant coatings protect against saline environments
.•
Disaster Resilience: PRESUB/U Underground Prefabricated Substations are designed to be flood-resistant for up to 72 hours, ensuring continuity during severe weather events
.
