The Vziman NGH-12 Series Environmentally Friendly Gas-insulated Metal-enclosed Switchgear have obtained KEMA certification.

Recently, Vziman Electric’s self-developed NGH-12 series of eco-friendly Gas-insulated Metal-enclosed Switchgear successfully obtained the internationally recognized IEC type test report issued by KEMA, covering both 50 Hz and 60 Hz frequencies. Specifically, the NGH-12 model passed KEMA’s E3-class tests for 12 kV applications, marking a significant technical breakthrough for Vziman in this field. KEMA certification is one of the most authoritative accreditations in the global power equipment industry, widely respected for its rigorous testing protocols and impartial evaluations.

Over several months of systematic testing, the NGH-12 series demonstrated full compliance with IEC international standards in critical performance areas—including insulation capability, electrical endurance, and internal arc resistance. The core innovation of this product line lies in its use of clean, dry air as an insulating medium, replacing conventional SF₆ gas to achieve zero greenhouse gas emissions. Combined with a compact design, user-friendly operation, and low maintenance costs, the NGH-12 series is ideally suited for urban grid upgrades, industrial power distribution, and renewable energy integration projects.
