American Standard Gas-Insulated Ring Main Units and Compact Switchgear

Applications include secondary power distribution systems, 6 kV to 40.5 kV medium-voltage gas-insulated ring main units and compact switchgear, encompassing traditional SF6 gas insulation and environmentally friendly dry air insulation. They offer high reliability, high safety, compact structure, and maintenance-free operation. Suitable for ring network units in secondary power distribution networks, various fixed configurations can meet the needs of most distribution networks.

Used in 6 kV to 40.5 kV distribution networks. Flexible expansion and fully modular or semi-modular configurations are available.

Intelligent solutions are based on advanced switchgear platforms, integrating various digital applications to form a complete solution, accurately sensing the status of the ring main unit. Utilizing cloud technology, it provides equipment asset health management and operation and maintenance suggestions, ensuring power supply safety, improving operational continuity and reliability, extending maintenance cycles, and reducing maintenance costs.

Suitable for: compact secondary substations, light industry, wind farms, residential buildings, hotels and shopping malls, mines, airports, railways, and subways.

High safety and reliability: Fully insulated and sealed structure; all live parts are sealed within the gas chamber, inaccessible and unaffected by the operating environment.

Flexible application: Each incoming and outgoing line unit can share a gas chamber or have an independent gas chamber; all functional units can be flexibly configured, and the cabinet dimensions are uniform.

Compact structure: Each functional unit is 325 mm wide for 12/24 kV and 420 mm wide for 40.5 kV.

Simple maintenance: Minimal maintenance required; the main body is maintenance-free.

Intelligent solution: Integrates multiple digital applications to form a complete solution, accurately sensing the status of the ring main unit.

Key Features: Meets ETL, UL, CE, CSA, and IEC certification standards.
