The High-Voltage Gas-Insulated Switchgear (HV GIS) platform ensures reliable power control in 72.5 kV to 1200 kV systems, utilizing SF₆ gas for insulation and arc quenching. With a modular three-phase enclosure design, it complies with IEC, GB, and ANSI/IEEE standards. The system integrates self-blast arc extinguishing technology and spring or hydraulic mechanisms, achieving 99.99% breaking efficiency for fault currents up to 63 kA. Its compact construction reduces footprint by 70% compared to traditional setups, while embedded smart sensors enable real-time monitoring of gas density and contact wear.
