Modular Ring Main Unit

This HXGN□-12 SF6 insulated modular ring main unit is a 12kV indoor metal-enclosed switchgear designed for three-phase AC 50Hz distribution systems. It is widely used in ring network power supply and terminal distribution applications as a complete packaged solution.

The equipment uses SF6 gas as both insulation and arc-extinguishing medium. The core switching units are sealed within a gas-filled chamber, providing excellent insulation performance and strong breaking capacity. The overall structure is highly compact, requiring minimal installation space.

Each functional unit adopts a modular independent design, allowing flexible configuration according to different ring network schemes. The cabinet is fabricated from high-quality welded steel plates, offering excellent mechanical strength and protection performance.

A complete mechanical and electrical interlocking system ensures safe operation, with full "Five-Prevention" functionality. The system operates with low noise, long maintenance intervals, and stable performance.

This equipment is widely used in urban distribution ring networks, terminal distribution systems, residential communities, commercial complexes, municipal projects, industrial parks, and data centers.

It is particularly suitable for 10kV indoor distribution applications requiring compact structure, high reliability, and efficient space utilization.

The company is a national high-tech enterprise certified under ISO9001 quality management, occupational health and safety, environmental management, and energy management systems. It has also been recognized as a municipal-level green factory, meeting advanced industry standards in both production and environmental protection.

The production facility is fully equipped with complete switchgear manufacturing and testing systems. Cabinet materials are strictly selected from high-quality cold-rolled steel and galvanized sheets, while core electrical components are sourced from leading international brands.

The company has strong production capacity, with a monthly output of up to 1,500 high and low voltage switchgear units, enabling large-scale order fulfillment. Quality control includes raw material inspection, in-process sampling, and 100% final product testing. Third-party inspection is fully supported before shipment, ensuring strict quality assurance for every unit delivered.
