NGH-40.5KV ENVIRONMENTALLY FRIENDLY GAS-INSULATED SWITCHGEA

The switchgear uses nitrogen (N2) as the insulating medium, which is readily available, clean, and environmentally friendly, while delivering excellent insulation performance to ensure safe and stable operation at zero gauge pressure. It features a modular design for long service life and reliable, stable performance; the three‑position disconnector and circuit breaker are integrated in a modular configuration, allowing for external assembly and convenient commissioning. An observation window on the gas compartment enables visual monitoring of the three‑position switch status. The equipment meets the stringent requirements of special environments, including high altitude, seismic resistance, and pollution resistance. With its block‑style expandability and modular assembly, it offers flexible scalability and easy maintenance. Moreover, it has achieved significant breakthroughs in zero‑gauge insulation and high‑current temperature rise, enabling seamless compatibility between SF6 and environmentally friendly gases.
