Description

NGH-12(Z) Environment-friendly Gas-insulated Metal-enclosed Switchgear Application: used in power stations, medium & small-sized power plant, substation, high-rise building, industrial and mining enterprises, subway, electrical railway and other power distribution systems, for the control, receiving, distribution, protection and monitoring of power supply systems and electric energy.​

• Eco-friendly Insulation：Adopts non-toxic, low-GWP (Global Warming Potential) gas instead of SF₆, eliminating greenhouse gas emissions and meeting strict environmental regulations (e.g., EU F-gas Directive).​
• High Safety & Reliability：All-metal enclosed structure with advanced sealing technology prevents gas leakage and resists external interference (dust, moisture, electromagnetic fields), ensuring stable operation in harsh conditions.​
• Compact Design：Space-saving structure reduces installation footprint by up to 30% compared to conventional switchgear, ideal for urban areas or sites with limited space.​
• Low Maintenance：Hermetic gas chamber and durable components minimize wear, extending maintenance intervals and reducing operational costs over the lifecycle.​
• Flexible Compatibility：Supports various wiring modes (ring network, radial) and integrates with smart grid systems, enabling remote monitoring and adaptive protection for intelligent power management.​
• Compliance with Standards：Certified by international norms (IEC, ANSI) for safety and performance, ensuring seamless integration into global power distribution networks.
