Premium-grade metal-enclosed MV distribution systems engineered for optimal thermal stability and mechanical endurance.
Hungary represents a vital gateway for Central and Eastern European industrial growth. Driven by huge foreign direct investments (FDI) in battery gigafactories (e.g., in Debrecen, Iváncsa, and Nyíregyháza) and extensive automotive manufacturing expansions (Győr and Kecskemét), the Hungarian grid is demanding robust and stable medium-voltage (MV) infrastructure.
Additionally, the Hungarian Transmission System Operator (MAVIR) and regional distributors are aggressively expanding solar photovoltaic integrations. To support this volatile green energy supply, high-end Air-Insulated Switchgear (AIS) must feature advanced grid-edge resilience, excellent thermal capabilities, and comprehensive smart integration to protect industrial loads and distribution lines.
Our medium-voltage switchgear is engineered for extreme load conditions, with advanced safety interlocking mechanisms and superior air gap clearances.

Zhejiang Zeno Electric Co., Ltd. - Empowering global and Hungarian utility grids with cutting-edge manufacturing excellence.
Zhejiang Zeno Electric Co., Ltd. is a national high-tech enterprise located in the major port city of Ningbo, with a registered capital of 52 million yuan. We integrate R&D, advanced manufacturing, international sales, and long-term service of power distribution components and comprehensive energy networks.
Supported by a strong domestic and international engineering team, Zeno Electric has steadily expanded its global footprint. Through consistent technological iterations and focus on reliability, we are trusted by utility grids, heavy petrochemical installations, data centers, and heavy infrastructure EPCs. We emphasize the development of intelligent, smart-grid compatible distribution systems, supporting global energy systems' digitalization.
High and low voltage complete distribution boards, switchgear cabinets (KYN28, KYN61, SM6), and modern ring main units.
Prefabricated substations designed for large photovoltaic (PV) utility fields and utility wind-turbine farms.
Turnkey electrical power grid construction up to 220kV, digital energy management systems, and smart EV fleet charging solutions.
From raw steel sheets to fully tested smart distribution panels, every production step follows standard operational protocols.
Explore our full line of ASTA certified Air-Insulated Switchgear (AIS) and Ring Main Units (RMU).
From Ningbo Port to Budapest & Debrecen, we guarantee robust transport packaging, localized commissioning support, and absolute standard conformity.
Navigating EU regulations requires more than just high-quality components. Zeno Electric provides complete CE conformity statements and ASTA type-test reports required by local grid authorities (such as MVM group companies and OPUS Titász).
All switchgear cubicles are shipped in marine-grade seaworthy wooden structures, with industrial desiccant packing to prevent humidity degradation during sea-and-rail combined transit via the China-Europe Railway Express or major shipping lines discharging at the Port of Koper / Rijeka and routed to Hungary.
Aligning with the European Union's ambitious F-Gas regulation timelines, Zeno Electric is pioneering high-reliability eco-friendly insulation technologies.
The European Parliament has set clear, legally binding phases for eliminating SF6 (Sulfur Hexafluoride) greenhouse gases in electrical switchgear. Medium-voltage networks are changing, and Zeno Electric is matching this trend by introducing the 24kV Dry Air Insulated Ring Main Units.
By using pressurized purified dry air as the primary insulating medium instead of SF6, our eco-friendly AIS and RMU variants emit zero greenhouse gases during operation, require no specialized F-gas recycling procedures at end-of-life, and completely shield operators from toxic decomposition products.
Additionally, we integrate predictive maintenance capabilities (IoT-linked optical temperature sensors and continuous partial discharge monitoring) to ensure substation lifespans of up to 40 years without manual system overhauls.
