Zhejiang Zeno Electric Co., Ltd. is a national high-tech enterprise located in Ningbo, with a registered capital of 52 million yuan. The company integrates research and development (R&D), manufacturing, sales, and service of advanced power equipment and energy systems.
Rooted in Ningbo and supported by a strong engineering and technical team, Zeno Electric has steadily expanded its business across China and international markets. Through continuous innovation and quality-driven development, the company has become a trusted provider in the power and energy industry, with growing influence in both utility and industrial sectors.
With a focus on sustainable development and smart energy transformation, we are committed to delivering safe, efficient, and intelligent power solutions that support the global transition toward cleaner and more digitalized energy systems.
Zhejiang Zeno Electric Co., Ltd. specializes in power equipment and integrated energy system solutions. Our product portfolio covers a wide range of advanced technologies, including:
In addition, we undertake turnkey power engineering projects up to 220kV, providing end-to-end services that include system planning, engineering design, equipment manufacturing, installation, commissioning, and long-term maintenance.
To better serve diverse customer needs, we offer fully customized, one-to-one energy solutions tailored to specific project requirements. Our integrated service model helps clients: simplify power application, reduce overall capital investment and operational costs, improve energy efficiency and reliability, and enhance smart monitoring capabilities.
Unlike traditional manufacturers focusing solely on hardware assemblies, Zeno Electric merges digital-twin energy management systems (EMS) with physical high-voltage distribution networks. This holistic integration enables predictive maintenance, dynamic load balancing, and thermal optimization directly within the primary power infrastructure, increasing battery system longevity by up to 28% and minimizing energy conversion losses.
Our state-of-the-art production plant guarantees unmatched build quality and precision compliance across all manufacturing steps.
High-precision laser and mechanical cutting of structural enclosures.
Controlled thermal treatment to enhance structural and material resilience.
Specialized leak-proof welding for high-voltage transformer units.
Evacuating all air pockets within transformer tanks for dielectric integrity.
Automated winding processes ensuring accurate electromagnetic ratios.
Vacuum casting of epoxy resin insulators for high dielectric strength.
Precision alignment and fitment of solid-insulated structural panels.
Complex core-and-coil alignment under controlled environment.
Strict dielectric, thermal, and load testing prior to factory dispatch.
Clean-cut plate shearing for perfect joint seals and protection.
High-speed CNC punching for ventilation pathways and assembly ports.
How modern C&I scale operations solve thermal, capacity degradation, and electrical conversion bottlenecks.
With the push toward 1C or even 2C charging/discharging speeds, traditional air-cooling structures exhibit massive hot spots. The integration of advanced liquid-cooled cold plates maintains cell-to-cell thermal variations within 2°C, preventing thermal runaway and mitigating capacity degradation over long life cycles.
Modern commercial and utility operators face rigorous dynamic tariffs. Optimization solutions utilize predictive algorithms to discharge stored wind or photovoltaic energy precisely during peak consumption rates. This minimizes grid stress and lowers commercial energy costs by exploiting arbitrage opportunities.
International markets demand compliance with stringent safety metrics, including UL 9540A, IEC 62619, and IEEE 1547. Zeno Electric integrates high-voltage isolation, solid-insulated switchgear, and multi-tier BMS redundancy to assure worry-free grid interconnection worldwide.
Achieving maximum efficiency in large-scale Battery Energy Storage Systems (BESS) requires co-optimizing electrical, thermal, and software systems. At Zhejiang Zeno Electric Co., Ltd., we combine state-of-the-art solid insulated ring network switchgear with intelligent containerized liquid-cooled configurations.
Our approach targets the three critical challenges of electrochemical storage systems: State of Charge (SOC) drift, localized thermal accumulation, and short-circuit fault propagation. By embedding high-voltage isolation breakers alongside automated liquid-glycol coolant networks, our architectures dynamically balance energy transfer across parallel battery racks.
Furthermore, our integrated substations merge medium-voltage distribution switchgear with high-performance inverter topologies, minimizing the footprint of solar and wind generation hubs. This unified platform reduces onsite commissioning time and ensures high reliability in harsh environments.
Standard air-cooled batteries operating at high ambient temperatures can experience capacity loss acceleration of up to 4% per year. By utilizing advanced liquid-chilled plate networks, we reduce the thermal variation between cells to less than 2°C. This maintains operation within optimal electrochemical ranges, extending the service life of Lithium Iron Phosphate (LFP) systems to over 6,000 cycles at 80% Depth of Discharge (DOD).
Our engineering and manufacturing practices are structured to satisfy the stringent requirements of utilities and grid operators worldwide.
We construct our medium-voltage switchgear, RMUs, and custom stainless steel power distribution cabinets in compliance with international IEC and IEEE standards. This ensures compatibility with local grid networks throughout Europe, the Americas, and the Asia-Pacific region.
From the initial design phase to installation and maintenance, our engineering team provides comprehensive support. We help streamline utility approval processes, conduct grid-connection feasibility studies, and deliver onsite commissioning services.
We provide tailored solutions to match local environmental and structural constraints. This includes IP65-rated enclosures for seaside solar farms, custom compact substations for urban shopping centers, and heavy-duty switchgear for high-altitude wind projects.
