Leading SF₆-free Gas-Insulated Switchgear for Sustainable Power Distribution
Nuventura manufactures SF₆-free gas-insulated switchgear (GIS) for 24 kV and 36 kV medium-voltage applications.
Our pioneering dry-air insulation technology eliminates SF₆ greenhouse gas while delivering industry-leading performance: 2500 A rated busbar current capacity, full IEC 62271-certification, and maintenance-free operation. As the leading SF₆-free switchgear manufacturer, we provide environmentally friendly alternatives to traditional gas-insulated switchgear without compromising reliability or performance.
Our innovative medium-voltage switchgear solutions replace SF₆ – the world's strongest greenhouse gas – with pure dry air whilst using vacuum circuit breakers, ensuring complete compliance with EU F-gas regulations and future environmental standards.

Why Choose SF₆-Free Medium-Voltage Switchgear?
IEC-certified SF₆-free gas-insulated switchgear (GIS) engineered for reliability,
compliance and optimal life-cycle performance.
Environmental Compliance & Future-Proof Technology
Nuventura's SF₆-free switchgear keeps utilities and industrial operators fully aligned with the tightening regulation around SF₆ in gas-insulated switchgear, including the EU F-gas Regulation. By replacing the insulating medium SF₆ with dry air, it removes the substance with the highest global warming potential in industrial use, cutting emissions and reducing the carbon footprint of the network without altering proven GIS behaviour. As a future-proof SF₆ alternative switchgear, it lets operators stay ahead of the SF₆ phase-out instead of retrofitting later.
IEC 62271-Certified Performance Standards
Every Nu1 medium-voltage switchgear unit undergoes rigorous IEC 62271-200 certification testing, guaranteeing reliable performance for critical power distribution infrastructure. Our type-tested designs meet the highest international standards for 24 kV and 36 kV voltage classes, ensuring safety and reliability across all applications.
Rapid Delivery & Installation Timeline
Experience seamless system integration with our modular switchgear architecture and standardized 20-to-28-week delivery timeline. Our compact footprint design optimizes space utilization while maintaining full compatibility with existing electrical infrastructure, making Nuventura the preferred choice for time-sensitive projects.
Maintenance-Free Dry-Air Technology
Advanced dry air insulated switchgear technology ensures maintenance-free operation throughout the equipment lifecycle, reducing operational costs and maximizing system uptime for utilities, renewable energy projects, and industrial applications. Unlike traditional SF₆-based systems, our dry-air insulation requires no gas monitoring, refilling, or special handling procedures.
