CEMarked CEMarked Explore our certified medium and low voltage switchgear units, dry-type and oil-filled distribution transformers, and power quality choke assemblies designed for mission-critical Paris installations.
Procuring medium voltage switchgear in Paris involves meeting specific French normative codes (NF C 13-100 and NF C 13-200) coupled with stringent Enedis distribution network connection constraints.
The urban network of Paris operates primarily on an underground looped 20 kV (HTA) primary distribution configuration. Medium voltage primary switchgear and secondary ring main units (RMU) require compact, footprint-optimized enclosures capable of withstanding high short-circuit duty cycles without thermal compromise in confined sub-basements.
Due to Paris's dense municipal environment and strict workplace safety mandates (INRS guidelines), switchgear installations demand verified IAC AFL or AFLR internal arc ratings up to 25kA/1s per IEC 62271-200. This ensures complete operator protection from high-energy arc flash events through dedicated rear or vertical gas-exhaust ducts.
In municipal substations governed by Enedis interconnect criteria, mechanical key interlocking (e.g., Profalux or Ronis systems) between the line disconnector, vacuum circuit breaker (VCB), and earthing switch remains mandatory. Our panels natively integrate standardized mechanical and electromechanical interlocks to avoid unsafe switching.
Explore where our medium and low voltage switchgear systems, power transformers, and harmonic filtration equipment deliver uptime and power quality.
Concentrated in the northern and western corridors of Paris (Saint-Denis, Aubervilliers, and Magny-les-Hameaux), colocation and hyperscale data centers require high-capacity 20kV MV incoming switchboards combined with MNS modular LV cabinets. Our systems offer continuous thermal monitoring and drawer-type rapid-replacement modules to prevent outage cascading.
The massive expansion of the Paris metro network via the Grand Paris Express requires reliable 15kV to 20kV traction substations. Our MV switchgear features vacuum circuit breakers rated for frequent mechanical switching operations and high impulse withstand voltages (BIL up to 125kV) to handle regenerative braking feedback and track transients.
Immeubles de Grande Hauteur (IGH) across the La Défense commercial district require compact dry-type cast resin transformers and SF6-free medium voltage switchgear. Strict municipal fire regulations prohibit liquid-dielectric transformers indoors; our dry-type copper split-winding units and metal-clad switchboards minimize fire hazard load while meeting NF C 13-100 codes.

Technical considerations for engineering teams specifying switchgear under upcoming European environmental regulations and smart-grid initiatives.
Under the revised EU F-Gas Regulation (Regulation EU 2024/573), the medium voltage sector is transitioning away from sulfur hexafluoride (SF6) due to its high Global Warming Potential (GWP 24,300). Paris commercial developers and public entities now prioritize air-insulated solutions and clean air or solid-dielectric vacuum switchboards for new tenders starting in 2026. Specifying non-SF6 equipment prevents costly lifecycle gas management and end-of-life disposal liability under French environmental compliance auditing.
The aggressive expansion of electric vehicle charging infrastructure (IRVE) across the Grand Paris metropolis, combined with commercial rooftop solar PV arrays, introduces severe harmonic distortion and bi-directional load currents. Modern medium voltage switchboards require integrated digital protection relays (IEC 61850 protocol) paired with DC link chokes and harmonic filtration assemblies to preserve transformer insulation health and maintain power quality at the point of common coupling (PCC).
Combining heavy-duty electrical engineering with computerized testing systems to serve industrial customers across Europe and worldwide.
Every switchgear assembly, transformer, and reactive component carries strict CE marking and complies with the Low Voltage Directive (LVD), Electromagnetic Compatibility (EMC), and relevant IEC standards for global and European grid interconnections.
Our 5,500 m² facility features automated testing panels for open/short-circuit verification, double voltage double frequency (DVDF) induced overvoltage testing, insulation resistance (Megger), and infrared thermal profiling prior to dispatch.
Rooted in complex control system architecture since 1990, we engineer switchgear with practical field experience: clean cable management, intuitive interlocking, integrated protection relays, and verified surge performance.
