Leverage air insulation
Use natural air and vacuum interrupters to avoid SF6 and F‑gases, improve sustainability and streamline recycling across the product’s long service life.
Why NXAIR?
NXAIR air‑insulated medium‑voltage switchgear delivers safety, reliability and sustainability for modern power distribution. Using natural air instead of SF6, it eliminates greenhouse gases and simplifies recycling. Certified with Siemens Ecotech for environmental responsibility, NXAIR meets IEC 62271‑200 standards and offers robust arc‑fault containment, interlocked operations and pressure relief for maximum protection. With digital monitoring, vacuum circuit breakers and long service intervals, it reduces lifecycle costs while ensuring high availability. Now enhanced with Low Power Instrument Transformers (LPITs) – tomorrow’s technology – integrating IEC 61869‑compliant sensors and SIPROTEC 5 relays for advanced digitalization and future‑ready performance.
