Switzerland’s electrical distribution system operates under strict regulatory supervision from the Federal Inspectorate for Heavy Current Installations (ESTI) and adheres to rigid European standards (EN 62271 / IEC 60502). As a direct manufacturer with integrated R&D, core cutting, coil winding, vacuum drying, and high-voltage testing bays, our factory bridges the gap between cost-effective Chinese manufacturing and uncompromising Swiss quality expectations. We provide full OEM/ODM engineering, complete Type-Test reports from independent bodies (such as KEMA, CESI, or accredited CNAS labs), and customized mechanical envelopes designed to fit within space-constrained Swiss transformer kiosks and subterranean substations.
Swiss medium voltage networks primarily operate at standard distribution levels of 12 kV, 16.7 kV (dedicated SBB traction power grid), 20 kV, 24 kV, and 36 kV at 50 Hz. Our switchgear and vacuum interrupters are engineered to handle continuous voltage fluctuations, high short-circuit withstand currents (up to 31.5kA / 3s), and precise vector group configurations specified by cantonal utilities such as EKZ, BKW, CKW, SIG, and EWZ.
A significant portion of Swiss installations are located in Alpine environments above 1,000 meters sea level. Lower atmospheric density reduces the dielectric strength of air insulation. Applying IEC 62271-1 altitude correction coefficients ($K_a$), we pre-engineer augmented creepage distances, enlarged phase-to-phase clearances, and specialized outdoor silicone bushings to eliminate flashover risks at high elevations up to 3,000m.
In accordance with the Swiss Ordinance on Chemical Risk Reduction (ChemRRV / ORRChem) and climate action mandates, Swiss utilities are phasing out SF6 gas. Our engineering team supplies eco-friendly dry-air insulated and vacuum-break medium voltage switchgear, providing zero global warming potential (GWP=0) while maintaining ultra-compact panel dimensions.

Proven equipment integration tailored for Switzerland's distinct industrial, municipal, and topographical requirements.
Switzerland generates over 60% of its electricity from run-of-river and storage hydro plants. Our 24kV and 36kV vacuum circuit breakers (ZN63/VS1 series) and copper XLPE power cables serve as critical links connecting alpine hydro-turbines to the high-voltage transmission grid. Engineered to withstand heavy thermal cycling, frequent switching operations, and moisture-rich environments typical of mountain caverns.
With rapid EV adoption along Swiss motorways (A1, A2 corridors), distribution operators require compact 24kV substations to feed multi-megawatt fast-charging hubs. Our modular MV switchgear panels and fire-retardant power cables deliver a small footprint, easy plug-and-play installation, and low acoustic noise for urban and highway rest-stop placements.
Swiss cantonal utilities prioritize subterranean cable routing to preserve natural landscapes and prevent winter storm outages. Our medium voltage XLPE insulated cables (up to 36kV) utilize high-purity conductor material, triple-extrusion insulation, and water-blocking tapes to ensure a 40+ year operational lifespan under wet alpine soil conditions.
Swiss manufacturing centers in Zurich, Basel, and Solothurn are actively upgrading legacy MV switchboards. Our side-mounted 24kV vacuum circuit breakers and custom switchgear chassis allow direct drop-in replacement into existing switchboard cubicles, dramatically reducing shutdown times during factory retrofits.
How our direct manufacturing model delivers technical transparency, rigorous quality control, and long-term security for B2B procurement.
Every medium voltage unit leaving our production line undergoes rigorous routine testing according to IEC standards: power-frequency withstand, partial discharge measurement (<5pC), primary current injection, contact resistance, and timing tests. Detailed FAT dossiers are supplied with every order.
Our distribution transformers and MV inductors feature precision foil-wound coils that eliminate axial short-circuit forces. Utilizing high-permeability, cold-rolled grain-oriented (CRGO) silicon steel cut on automated step-lap lines, we guarantee exceptionally low no-load and load losses.
We provide full export-compliant seaworthy/airworthy packaging, nitrogen-purged shipping options for heavy switchgear, and complete documentation support (CO, EUR.1, commercial invoice, packing list) for smooth customs clearance through Basel, Geneva, or Zurich freight hubs.
