"Through persistent technological exploration and structural integration, we develop safe, efficient, and intelligent transmission and storage systems that empower global operators to successfully execute decarbonization pathways."
Integrated power generation, high-voltage distribution systems, and complex battery energy storage engineering solutions.
Manufacturing intelligent high and low voltage complete distribution equipment including KYN28 air-insulated panels and XGN80 gas-insulated switchboards designed for reliable power management.
Delivering utility-scale and commercial/industrial containerized lithium-ion BESS solutions from 50kWh to multi-megawatt configurations (1MWh - 5MWh) with advanced Liquid/Air-cooling integration.
Developing outdoor prefabricated, box-type compact substations specifically configured for wind power, solar integration, and high-voltage transmission lines up to 220kV.
In addition to our extensive physical technology portfolio, we provide full turnkey engineering capabilities for power substations up to 220kV, supporting clients from Initial Grid Feasibility Studies and System Design to manufacturing, on-site commissioning, and regulatory approval. We actively streamline approvals, lower investment outlays, and provide modular architectures for optimized asset lifespans.
Zeno Electric operates state-of-the-art production lines in Ningbo. Below is an overview of our specialized engineering and manufacturing steps.
Our manufacturing complex utilizes high-speed automated shearing, laser cutting, and specialized winding infrastructure. Advanced casting and vacuum oil-pumping systems guarantee that our high-voltage transformers achieve superior insulation class ratings. The factory leverages automated testing bays to perform routine and type testing, verifying partial discharge ratios, insulation resistance, and thermal thresholds prior to packaging. Being located in Ningbo, we sit at the crossroads of China's premier electrical supply chain and container ports, ensuring reduced freight cost structures and reliable global dispatch timelines.
Pioneering clean energy technologies designed to meet the technical challenges of 2030 grid compliance.
The modernization of the electrical grid calls for high-voltage and medium-voltage switchgear that goes beyond traditional physical insulation. Zeno Electric is advancing SF6-free (Sulfur Hexafluoride) green gas-insulated switchgear (GIS) and air-insulated switchgear (AIS) that incorporate localized sensors and micro-RTUs. By utilizing optical temperature sensors and intelligent vacuum circuit breakers, our systems support real-time telemetry, enabling predictive maintenance schedules and reducing grid down-time.
We are optimizing our standard lithium iron phosphate (LFP) cell architectures to support next-generation chemistry integrations, including sodium-ion and hybrid configurations. In terms of thermal safety, our technology roadmap emphasizes intelligent liquid cooling systems that regulate individual rack temperatures to within ±2°C. This significantly minimizes cell aging degradation and mitigates thermal runaway risks in large-scale solar-plus-storage applications.

Turnkey power integration architectures engineered for demanding global market segments.
Our prefabricated compact outdoor substations (up to 35kV / 2500kVA) and step-up power transformers act as the primary interface between variable solar fields, wind fields, and high-voltage transmission lines, ensuring stable active and reactive power injection.
For industrial facilities, manufacturing complexes, and EV fast-charging parks, Zeno provides modular 50kW to 200kW battery enclosures alongside smart power conversion systems (PCS). These technologies lower utility peak demands and supply uninterrupted backup power.
Our containerized utility BESS layouts (1MWh to 5MWh) are designed to provide frequency response, voltage support, and energy arbitrage capabilities, allowing transmission system operators (TSOs) to maximize grid resilience.
Deploying advanced power distribution and battery energy systems globally requires strict compliance with international testing regimes and electrical grid codes. Zhejiang Zeno Electric Co., Ltd. builds products designed to satisfy the rigorous certification standards of regional jurisdictions.
Our switchgear panels, ring main units, and outdoor substations comply with the testing procedures of the International Electrotechnical Commission (IEC), including IEC 62271-200 for AC metal-enclosed switchgear. Additionally, our containerized BESS arrays are engineered to meet key global regulatory certifications:
To support global EPC contractors and developers, we provide comprehensive technical services, including remote FAT (Factory Acceptance Testing) oversight, virtual commissioning guidance, and on-site support through local service partners. Our engineering team conducts grid-impact simulations (load-flow, short-circuit, and harmonic studies) to verify that our high-voltage switchgear and BESS installations integrate seamlessly with local grid configurations.
A structured process path designed to align engineering expectations, from project RFP to international shipping.
As a key supplier of clean energy technologies, we streamline the procurement cycle for international EPCs, utility operators, and industrial clients. Below is a breakdown of our standardized engineering and delivery workflow:
Every electrical grid operates under unique local constraints. We review single-line diagrams (SLDs), step-up requirements, environmental conditions (e.g., C5 anti-corrosion for coastal solar installations), and communication requirements (IEC 60870-5-104 or Modbus TCP) to customize our equipment specifications.
Every switchgear unit, distribution box, transformer, and BESS container undergoes strict quality testing prior to dispatch. This includes dielectric tests, protection relay verification, cell balance assessments, and thermal cycling audits.
Leveraging our 52 million yuan capitalization and our facility in Ningbo, we manage raw materials, copper, LFP cells, and vacuum interrupters to stabilize production timelines. Typical Lead Times are:
Our close proximity to the Port of Ningbo allows us to execute sea freight, heavy-lift transport, and DDP/CIF deliveries quickly and efficiently.
