Overview
The XGN-12 Series gas-insulated switchgear has successfully obtained the type test report from the China High Voltage Electrical Appliance Test Center, and moreover, it has been recognized as a Zhejiang Provincial High-tech Product. Widely used in 10kV/20kV power distribution systems, it has become the preferred choice for switching and distribution applications across a broad range of urban and rural infrastructure projects.
Designed with a modular unit structure, the switchgear allows flexible combinations according to different application needs. It is available in two main configurations: a fixed unit and an expandable unit, thereby enabling adaptable deployment in various compact substation environments.
