Product Introduction

The XGN□-40.5 (Eco-friendly) series gas-insulated switchgear is used in 40.5kV systems with gas-insulated metal-enclosed switchgear, featuring vacuum arc extinction and N2 insulation at a slight positive pressure of 0.02MPa. It is environmentally friendly, unaffected by external conditions, and offers simple operation, full enclosure, maintenance-free design, and a long lifespan. It is widely applied in harsh environments such as humid, salt-spray, and high-altitude areas.

Product Features

N2 insulation, vacuum arc extinction, supporting "carbon peak and carbon neutrality" green environmental goals.

Superior insulation performance, meeting insulation requirements at zero gauge pressure, with partial discharge <10pC.

Compact and reliable structure, saving space, with a 40% reduction in volume compared to traditional switchgear.

Special heat dissipation structure, achieving 1.1×2500A natural heat dissipation.

Advanced process control, laser welding, and helium leak detection ensure gas tank sealing performance.

Meets State Grid standardization requirements, with strong interchangeability and adaptability.

Fully enclosed and unaffected by environmental conditions, moisture-proof, dust-proof, and pollution-resistant, suitable for altitudes up to 5000m.

High performance, with a mechanical lifespan of 20,000 operations, maintenance-free, and a product lifespan of up to 30 years.

Direct-acting three-position switch with reliable connection and strong alignment stability.

Fully electric operating mechanism, one-key sequential control, reliable, convenient, and fast operation.
