For secondary distribution systems, 6 kV to 40.5 kV medium-voltage gas-insulated ring main units and compact switchgear
SafeRing/SafePlus gas-insulated ring main units and compact switchgear include traditional SF6 gas insulation and eco-friendly dry air insulation, offering high reliability, high safety, compact structure, and maintenance-free operation.
SafeRing is suitable for ring main units in secondary distribution networks, with multiple fixed configurations capable of meeting the requirements of most distribution networks.
SafePlus is a metal-enclosed compact switchgear used in distribution networks from 6 kV to 40.5 kV. SafePlus switchgear can be flexibly extended and combined in fully modular or semi-modular configurations. Both SafeRing and SafePlus belong to the same product family and share the same user interface.
Safe Digital intelligent solutions are based on ABB's advanced Safe switchgear platform, integrating multiple digital applications to form a complete solution that accurately senses the status of the ring main unit. Leveraging ABB ABILITY cloud technology, it provides asset health management and operation and maintenance recommendations, ensuring power supply security, improving operational continuity and reliability, extending maintenance cycles, and reducing maintenance costs.
Applications: compact secondary substations, light industry, wind power plants, residential buildings, hotels and shopping centers, mines, airports, railways, and subways
High safety and reliability
Fully insulated and fully sealed structure, with all live parts sealed inside the gas tank, inaccessible and protected from operating environment influences
Flexible application
Each incoming and outgoing unit can share a common gas tank or have an independent gas tank; all functional units can be flexibly configured, with identical cabinet dimensions
Compact structure
Each functional unit is 325 mm wide for 12 / 24 kV, and 420 mm for 40.5 kV
Low maintenance
Minimal maintenance required, with the main components achieving maintenance-free operation
Intelligent
Integrates multiple digital applications to form a complete solution, accurately sensing the status of the ring main unit
