Explore our highly robust, CE-compliant intelligent power hardware tailored for utility systems, high-voltage substations, and industrial renewable energy architectures.
The international power transmission sector is experiencing a paradigm shift towards decarbonized, localized, and highly automated topologies. Driven by the accelerated integration of volatile renewable generation sources such as solar photovoltaics and wind turbines, conventional grid infrastructures are proving inadequate. Modern commercial operations demand highly adaptive power delivery systems capable of mitigating voltage fluctuation, managing bidirectional currents, and offering sub-millisecond switching performance.
Across Europe, Asia-Pacific, and the Americas, regulatory frameworks are mandate-focused. Decarbonization goals, coupled with stringent grids codes, require distribution hardware that maintains system frequency stability. Our CE Certified Smart Grid Solutions address these requirements directly. By combining heavy manufacturing proficiency with IoT automation systems, Zeno Electric provides the physical and digital architecture required to orchestrate complex power corridors.
Managing transient harmonics, dynamic voltage restoration, and rapid step-up capabilities from fluctuating wind and solar field operations.
Providing containerized energy storage units to store surplus power and perform peak shaving, load balancing, and black-start utilities.
Leveraging modern PLC, SCADA, and IEC 61850 protocol standards to provide absolute visibility into grid metrics and distribution loops.
CE Certification is not merely a regulatory entry stamp; it represents a commitment to safety, structural reliability, and electromagnetic compatibility. For heavy electrical equipment operates in high-voltage environments (from 10kV distribution grids up to 252kV transmission stations), compliance validates that the equipment has undergone exhaustive testing for dielectric strength, impulse withstand voltage, and environmental durability.
Zeno Electric's smart grid products are engineered to comply with harmonized European standards, including the Low Voltage Directive (LVD) 2014/35/EU, the Electromagnetic Compatibility (EMC) Directive 2014/30/EU, and specific IEC/EN standards for gas-insulated switchgear (EN 62271) and distribution transformers (EN 60076). This ensures our global buyers can deploy equipment into public utility grids and high-risk commercial setups without concern for grid instability or non-compliance penalties.
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.
Quality is designed and manufactured into our equipment. Our Ningbo production base is equipped with CNC machining, high-purity casting, laser cutting, automated winding, vacuum potting, and state-of-the-art test bays for partial discharge, impulse voltage, and thermal rise testing. We ensure every unit leaving our facility adheres to international standards.
Zeno Electric delivers more than individual products; we design integrated systems. Our turnkey capability up to 220kV helps project managers, procurement directors, and grid operators simplify their supply chains and speed up deployment.
Integrating wind and solar energy into existing grid frameworks requires specialized step-up substations. Our compact box substations, designed for 10kV to 35kV topologies, feature ONAN oil-immersed transformers and high-voltage disconnectors. They are designed to withstand thermal cycles and high solar irradiance while delivering power with low harmonics.
Integrating a containerized BESS requires coordination between battery modules, thermal management, fire safety, and the power conversion system (PCS). We deliver modular container systems (ranging from 500kW/1MWh to 1.2MWh capacity) equipped with smart EMS (Energy Management Systems) that interface with distribution networks to provide frequency regulation, demand charge reduction, and backup power.
For critical substations, space constraints and safety are major factors. Our customized GIS (Gas Insulated Switchgear) and AIS (Air Insulated Switchgear) assemblies range up to 252kV. These systems feature compact footprints and high-voltage circuit breakers designed for reliable arc extinction and minimal maintenance.
High-power EV charging parks require local distribution networks to prevent grid overloading. Zeno Electric integrates low-voltage switchgear, PLC automation panels, and dry-type step-down transformers to balance local loads dynamically and optimize real-time power consumption.
Zeno Electric solutions are engineered to perform across diverse operating environments globally:
Our R&D division is focused on carbon-neutral distribution systems. Key research paths include:
Phasing out SF6 gas with eco-gas alternatives and dry-air insulated ring main units to reduce environmental impact.
Integrating high-performance microprocessors directly into outdoor switchgear to support real-time edge processing.
Developing next-generation converters to manage high-frequency power flow and bidirectional grid integration.

An H-class insulation system is rated for an operating temperature limit of 180°C. In commercial dry-type transformers, this is achieved using high-grade Nomex materials and specialized resin systems. This rating allows the transformer to handle high-temperature peaks, making it suitable for data centers and wind farms that experience volatile loads.
Our containerized BESS uses a multi-layered safety approach: cell-level monitoring via high-precision BMS, local liquid-cooling or forced-air cooling channels to regulate temperatures, and fire detection systems (using Novec 1230 or Aerosol suppression) to quickly isolate and extinguish thermal issues.
SF6 insulated switchgear utilizes sulfur hexafluoride gas for arc interruption due to its high dielectric strength, enabling compact designs. Dry-air insulated Ring Main Units (RMU) substitute SF6 with pressurized dry air or nitrogen mixtures. While this requires different internal design configurations to manage dielectric distances, it eliminates SF6 greenhouse gas risks.
Because they are fully integrated and pre-tested at our Ningbo factory, the on-site work is minimized. Cable runs, switchgear connections, transformer settings, and control relays are pre-wired and pre-commissioned, reducing typical field-assembly schedules by up to 60%.
Our complete low-voltage and medium-voltage smart switchgear cabinets support modern protocols like Modbus RTU/TCP, DNP3, and IEC 61850. This enables seamless connection with utility SCADA systems, industrial PLC networks, and cloud-based energy management portals.
Vacuum pumping extracts residual moisture and air bubbles trapped within the core laminations and winding papers. If left untreated, these bubbles can lead to partial discharges under high electrical stress, degrading the insulation fluid and risking dielectric breakdown.
All our substation designs, high-voltage installations, and engineering projects align with the International Electrotechnical Commission (IEC) guidelines, IEEE standards, and regional grid connection codes (such as EN 50549 for European grid access).
These enclosures feature dual-wall ventilation systems, dust/water ingress protection (IP55 to IP66 ratings), heavy-duty security locks, and anti-condensation heating elements to protect delicate solar inverters and monitoring systems.
