HXGN15-12(SF6) Box-type Fixed AC Metal-enclosed Ring Main Unit (RMU) Switchgear A Compact and Reliable Solution for Modern MV Networks

In modern medium-voltage distribution systems, compact and maintenance-friendly switchgear is essential for reliable power supply in urban and industrial areas. The ring main unit (RMU) serves as a key node for network segmentation, load transfer, and fault isolation, ensuring continuous operation and easy maintenance. Designed for 12kV applications, the fixed-type RMU provides a robust and space-saving solution for a wide range of distribution scenarios.

The HXGN15-12(SF6) RMU employs SF₆ gas as the insulating and arc-quenching medium, offering excellent dielectric strength and operational safety in a compact enclosure. Its metal-sealed design ensures protection against environmental influences, making it suitable for indoor and outdoor installation. With integrated load break switches, earthing switches, and fuse combinations, this RMU allows for flexible feeder configurations, reliable load breaking, and visible isolation, meeting the needs of modern grid architectures.

As a core product in Putai's RMU portfolio, the HXGN15-12(SF6) unit stands out for its fully enclosed structure, stable performance, and compliance with international standards such as GB and IEC. Its fixed installation design reduces maintenance requirements, while the SF₆ insulation ensures long-term reliability even in limited spaces. Suitable for transformer switching, cable charging, and ring network applications, this RMU enhances system safety and simplifies grid operation.

Putai supports customization and provides compatible medium-voltage accessories to meet integrated system requirements, ensuring seamless adaptation to various project needs. Whether for utility networks, commercial complexes, or industrial plants, the HXGN15-12(SF6) RMU delivers a future-ready and efficient distribution solution.
