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.
Our manufacturing philosophy revolves around absolute system integration. We bridge the gap between heavy power grid structures and digital control layers. Over the last decade, Zhejiang Zeno Electric Co., Ltd. has developed proprietary configurations of low-voltage switchgears that resist harsh seismic, chemical, and physical parameters, ensuring unbroken uptime for heavy industry, mining, and smart urban distribution 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. We deliver fully customized, one-to-one energy solutions tailored to specific project requirements.

Prefabricated compact utility substations customized specifically for wind farms and solar photovoltaic installations in remote, high-altitude locations.
Smart medium-voltage switchgear cabinets featuring gas-insulated SF6 configurations and alternative ecological gas options for sustainable operations.
Intelligent alternating and direct current charging piles, integrating payment modules and localized grid connection communication interfaces.
Advanced cloud-native software and monitoring units designed to track, audit, and analyze power profiles in industrial production processes.
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.
Our one-to-one energy system planning simplifies compliance, reduces capital expenditure, improves energy efficiency, and introduces remote IoT monitoring to standard electrical boards.
At Zhejiang Zeno Electric Co., Ltd., we control the entire lifecycle of our switchgear and transformers. Under strict Quality Management Systems, our Ningbo facility utilizes advanced CNC machinery, heavy stamping installations, automated winding, vacuum sealing, and high-voltage laboratories to prevent any insulation or structural failure.
As global industries seek to optimize operational efficiency and minimize carbon footprints, the demand for smart, low-carbon low-voltage switchgears has intensified. Our R&D team at Zhejiang Zeno Electric Co., Ltd. focuses on three core pillars:
1. Smart Integration (IoT & Cloud Connect): By embedding Intelligent Electronic Devices (IEDs), smart sensors, and advanced communication modules directly into our low-voltage fixed (GGD) and draw-out (MNS, GCK) cabinets, we enable real-time thermal analysis, predictive maintenance alerts, and wireless power-quality monitoring. These setups integrate directly with industrial SCADA platforms via Modbus, Profibus, or IEC 61850 protocol suites.
2. Eco-Friendly Insulation & Safe Gas Technologies: Aligning with global targets to phase out high-GWP gases, we lead in testing alternative insulation media for gas-insulated cabinets. By employing dry air or nitrogen gas-insulated cabinets, Zeno Electric provides clean alternatives without compromising dielectric strength.
3. Advanced Mechanical Durability & Safety: Designing switchgear requires deep knowledge of structural physics. We construct our cabinets with high-grade galvanized steel sheets and customized copper busbar routing to resist dynamic forces and prevent internal arc faults.
Modern high-performance infrastructure requires tailored electrical design. Zeno Electric's solutions scale across major industries:
Global procurement departments look for reliable suppliers that offer high quality, stable prices, and compliance with local safety standards. Zhejiang Zeno Electric Co., Ltd. aligns with international buying parameters:
We minimize shipping costs, offer competitive direct factory prices, and design low-loss systems to lower overall operating costs.
We collaborate via 3D CAD modeling and digital twin planning, aligning customized configurations with your local grid layout before production starts.
We track copper, aluminum, and insulation components from certified raw materials to the final functional test.
Shipping heavy high/low voltage switchgear worldwide requires compliance with local standards. Zeno Electric structures its production according to global expectations:
IEC & EN Standard Conformity: All low-voltage and medium-voltage complete switchgear systems conform to basic regulations including IEC 61439-1 / IEC 61439-2, ensuring strict limits for temperature rise, short-circuit withstand capabilities, dielectric performance, and mechanical operation.
CE Certification & Type Testing: Our products carry CE certification and undergo routine inspections in third-party labs. This confirms safety, electromagnetic compatibility (EMC), and environmental safety under EU Directives.
On-Site & Commissioning Support: To reduce risks during install, Zeno Electric provides complete documentation, detailed wiring diagrams, and engineering guidance. We also offer on-site engineering supervision and digital remote assistance during the commissioning phase to verify alignment with local codes.
Technical answers to help engineers, plant managers, and procurement professionals evaluate switchgear design.
Fixed-type switchgear (like the GGD model) uses components bolted directly onto the inner frame. It is cost-effective and suited for simple distribution tasks where shutdown maintenance is planned. Draw-out switchgear (like MNS or GCK) places circuit breakers and control components into individual slide-out drawers. This allows technicians to replace units quickly under live or hot conditions, minimizing downtime in critical plants.
Ingress Protection (IP) ratings indicate dust and water resistance. IP40 prevents solid foreign objects (>1mm) from entering, making it suitable for clean, indoor electrical rooms. IP54 adds splash water protection, while IP55 protects against dust build-up and direct water jets. IP55 enclosures are designed for harsh outdoor installations, heavy manufacturing facilities, or locations exposed to high humidity.
Sulfur Hexafluoride (SF6) has excellent insulation properties but is a potent greenhouse gas. Zeno Electric offers eco-friendly options, including alternative nitrogen gas-insulated cabinets or gas-free air-insulated systems. These options meet safety standards while minimizing environmental impact.
Every switchgear is engineered with computer-aided electro-magnetic and thermal simulation tools. We structure the spacing, physical positioning, and bracing of our copper busbars using high-strength composite insulators. This ensures the copper system can withstand short-circuit forces without mechanical distortion or insulation failure.
