The HG3 environmentally friendly gas-insulated metal-enclosed switchgear (C-GIS) is a cutting-edge product independently developed by our company. It uses clean air as the insulating medium, making it an environmentally friendly alternative to traditional gas-insulated switchgear. This product integrates vacuum arc-extinguishing technology, APG solid-sealing technology, gas insulation technology, and interface insulation technology into a new generation of medium voltage switchgear. The product complies with IEC62271, GB11022, GB3906, DL/T404, and other relevant standards. It has passed all type tests and has been recognized through China’s national-level new product technical evaluation.

The HG3 switchgear is widely applied in various power systems, including transmission and distribution networks, urban power grids, large industrial and mining enterprises, petrochemical industries, metallurgy, and urban rail transit systems.

Key Features:

Environmentally Friendly Insulation: Uses clean air as the insulating medium, with no use of SF6 gas and no toxic gas emissions, ensuring no environmental impact and classifying it as a green, environmentally friendly product.
Compact, Modular Design: The product features a compact structure with a small footprint, making it space-efficient.
Sealed High-Voltage Components: High-voltage components are sealed within a stainless steel enclosure, making the switchgear waterproof, dustproof, and unaffected by environmental factors, including altitude. The design ensures safe and maintenance-free operation.
Flexible Primary Scheme: The product offers versatile primary schemes to meet the varying connection requirements of different systems.
Intelligent Control and Protection Units: Equipped with powerful control, protection, and measurement functions, the switchgear fully meets the requirements of distribution network automation.
Reliable Mechanical and Electrical Interlocks: The product includes reliable mechanical and electrical interlocks that effectively prevent misoperation, ensuring convenient and reliable operation.
