Explore our top-tier Gas-Insulated Switchgear models designed to meet France's strict grid modernization goals and high safety tolerances.
The transmission and distribution system in France, managed primarily by RTE (Réseau de Transport d'Électricité) and Enedis, demands the highest standards of hardware reliability and environmental protection. As France accelerates its transition towards carbon neutrality by 2050, electrification of transport and heating increases load density, stressing existing switchgear.
Under these conditions, Gas-Insulated Switchgear (GIS) plays a critical role. By substituting air insulation with high-dielectric SF6 or eco-gases, GIS units reduce substation footprints by up to 70% compared to traditional Air-Insulated Switchgear (AIS). This is vital for space-constrained metropolitan areas like Paris, Lyon, and Marseille, as well as sensitive historic sites where visual impact must be minimal.
French local distribution relies on specific safety procedures and protection protocols. Medium Voltage RMUs must feature robust mechanical interlocks to prevent operator error and ensure seamless integration with French SCADA systems (HN 64-S-41 and similar standards). Our GIS units offer direct-mount low-power current/voltage sensors (LPITs) to support modern digital grid telemetry.

For European and French markets, safety is paramount. All Zeno Electric GIS products conform strictly to the IEC 62271 product family standards and bear the CE mark. Furthermore, our designs factor in the environmental constraints imposed by the EU F-gas regulations (Regulation EU 2024/573), which enforce strict record-keeping and minimization of SF6 leakage.
To ensure high E-E-A-T credentials, our manufacturing lines employ helium leak testing chambers that detect microscopic faults. Our gas compartment welds are performed by robots under inert gas shields, assuring zero maintenance requirements over a design life exceeding 30 years.

Trace our systematic quality controls inside our Ningbo facility. Every stage, from raw metal to complete gas sealing, is executed to meet international grid-hardware standards.
Decarbonizing industrial zones such as Dunkirk, Le Havre, and Fos-sur-Mer requires upgrading electrical infrastructure to accept clean renewable generation and high-capacity connections. Traditional switchgear substations are impractical for heavy industrial plant retrofits where space is constrained by manufacturing plants, reactors, or steam networks. Zeno Electric's GIS provides optimized deployment options for:
Additionally, our digital intelligent energy management systems integrate with GIS sensors to provide real-time thermal analysis and predict equipment life cycles, minimizing unexpected grid outages.
A typical 20kV / 24kV medium-voltage connection inside a French industrial facility uses a Ring Main Unit (RMU) to loop feed the facility. Our modular GIS allows expanding the substation busbar in the future without the need for gas recovery or on-site welding, saving precious commissioning time.

Sourcing Gas-Insulated Switchgear for French utility or heavy industrial infrastructure requires evaluating more than just the initial capital expenditure (CAPEX). High maintenance and gas leakage penalties under EU law can rapidly increase operational costs (OPEX). Zeno Electric minimizes OPEX through precision engineering:
