Product Introduction
As primary distribution equipment for gas-insulated single and double busbar systems, the XGNZ9 is mainly applied in substations, distribution stations, and various infrastructure projects including buildings, government offices, steel plants, rail transit facilities, and water treatment projects. It is also applicable to other industries that meet the relevant electrical parameter and design scheme requirements.
Safety
All functional compartments are fully independent. High-voltage components are completely sealed and free from external interference. The insulation performance remains unaffected by the on-site altitude. Equipped with a comprehensive interlock and locking design, as well as reliable internal arc resistance performance, the equipment fully ensures operator safety.
