Hertzman (Hangzhou) Power Technology Co., Ltd. is a Sino-foreign joint venture specializing in R&D, manufacturing, and integrated solutions for power distribution components and systems. Committed to technological excellence and sustainability, the company focuses on delivering high-reliability, intelligent, and compact products tailored to global power industry needs.
Core Competencies & Vision Hertzman’s mission is to "become the master of knowledge, the leader in technology and manufacturing processes, achieve sustainable enterprise development, and continually meet power users' demands." This vision drives innovation across its product lines, including medium/low-voltage switchgear, circuit breakers, ring main units (RMUs), compensation systems, and smart grid solutions.
Product Portfolio Overview Medium/High Voltage Switchgear & RMUs:
NXSAFE Series: Metal-clad removable AC switchgear (12kV–40.5kV) compliant with IEC 62271-200/GB3906. Features include arc-resistant design, independent pressure-relief channels, "five-prevention" interlocking, and ratings up to 5000A/40kA.
NXGEAR: Armored fixed-type metal-enclosed switchgear for substations.
R-AIR: Atmospheric sealed air-insulated switchgear using dry air instead of SF₆, ideal for secondary distribution.
NXRING: SF₆ gas-insulated RMUs (12kV) with modular units (load switches, circuit breakers, fuse combinations).
NXGIS-40.5: Gas-insulated switchgear for 40.5kV systems.
Circuit Breakers:
VHZ4/VHZ4i Series: Intelligent vacuum circuit breakers (12kV–40.5kV) with real-time monitoring, modular mechanisms, and ratings up to 4000A/50kA. Includes side-mounted, withdrawable, and fast-acting (VHZ4M) variants.
EXT/EXE Series: Low-voltage air/molded-case circuit breakers (400V–690V) with HILogic controllers, supporting remote control and IoT integration.
Low-Voltage Systems:
EXSINE: Draw-out low-voltage switchgear (≤6300A) with IP54 protection, arc-flash detection, and DAVIDCLOUD smart monitoring.
EXVAR/EXTSC/EXCA/EXRE: Reactive power compensation solutions, including intelligent capacitors, thyristor switches, and series reactors.
EXAPF: Active filters for harmonic mitigation (25–300kVar).
Monitoring & Control:
HIMETER194: Multifunctional power meters for energy management.
MIC300/MIC500: Protection relay and control devices for transformers, lines, and generators.
DAVIDCLOUD: Cloud-based intelligent operation and maintenance system enabling remote monitoring, diagnostics, and predictive maintenance.
Specialized Solutions:
NXATS: Medium-voltage dual-power automatic transfer systems.
NXLINE/EXLINK: Quick-coupling connectors for emergency generator/EV charging integration.
Containerized Energy Storage & PV Inverter Systems: Renewable energy integration platforms.
Technical Highlights
Safety & Reliability: All switchgear undergoes rigorous arc-testing (IAC A FLR 31.5kA/1s), with IP67-sealed gas compartments and visual isolation breaks.
Smart Features: IoT-enabled devices with RS485/Modbus, cloud connectivity, and real-time analytics.
Eco-Innovation: SF₆-free designs (R-AIR, SOGEAR) and recyclable materials.
Modularity: Standardized components ensure scalability and ease of maintenance.
