Outdoor Switchgear

The XGW-12 Series Primary and Secondary Fusion Standardized Ring Cage (Switching Institute) is an advanced SF6 gas-insulated outdoor ring main unit (RMU), independently developed and manufactured by our company. This product is specifically designed based on the unique characteristics of power distribution networks across various regions of China, as well as the practical requirements of urban distribution network cable transformation projects.
The XGW-12 series integrates primary and secondary equipment into a standardized, modular, and highly compact switching solution. It is engineered with a focus on modularity, scalability, high insulation performance, complete gas sealing, operational safety, and maintenance-free design. To enhance intelligent operation and grid reliability, the unit is also equipped with optional features such as wireless temperature measurement and online monitoring devices.
Thanks to its robust construction and full insulation design, the XGW-12 series performs reliably even in harsh environmental conditions, including high humidity, extreme temperatures, and polluted areas. This makes it an ideal choice for a wide range of urban and industrial power distribution applications, including:
Industrial parks
Residential communities
City streets and boulevards
Airports and transportation hubs
Various types of commercial and public buildings
Busy business centers and high-density urban areas
With its excellent adaptability, intelligent monitoring capabilities, and maintenance-free operation, the XGW-12 series significantly improves the safety, stability, and automation level of medium-voltage distribution networks.
