The HG9-24 Environmentally Friendly Gas-Insulated Metal-Enclosed Switchgear (C-GIS) is a cutting-edge product independently developed by our company, utilizing clean air as the insulating medium. This environmentally friendly gas-insulated switchgear represents a new generation of medium voltage switchgear, integrating vacuum arc-extinguishing technology, APG solid-sealing technology, gas insulation technology, and interface insulation technology. The product meets international standards, including IEC62271, GB11022, GB3906, and DL/T404, and has passed all type tests and China’s national-level new product technical evaluations.

The HG9-24 switchgear is widely used in various power systems, such as 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: The switchgear uses clean air as the insulating medium, eliminating the need for SF6 gas, with no toxic gas emissions, ensuring no environmental impact. It is classified as a green, environmentally friendly product.
Compact and Modular Design: The product features a compact structure with a small footprint, making it space-efficient and suitable for installations with limited space.
Sealed High-Voltage Components: High-voltage components are enclosed within a stainless steel case, 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.
