For Medium-Voltage Secondary Distribution Networks up to 12 kV
SafeRing / SafePlus Air eco-friendly gas-insulated ring main unit and compact switchgear successfully use dry air as a substitute for SF6 gas in switchgear, endowing the equipment with excellent environmental and safety performance, while inheriting the advantages of gas-insulated products in terms of compact structure and maintenance-free operation.
Dry air is a commonly used industrial gas that requires no maintenance or recovery treatment by customers, as it can be directly released into the atmosphere without causing any harmful impact on the ecological environment.
SafeRing / SafePlus Air eco-friendly gas-insulated ring main unit and compact switchgear inherit the mature manufacturing processes and operational experience of existing gas-insulated switchgear, ensuring stable and reliable product operation to a large extent. They exhibit strong environmental adaptability and can be applied in industrial environments such as those with sandstorms, humidity, and pollution. Multiple functional units can be sealed within the same gas compartment, resulting in a more compact structure and reduced on-site installation workload.
Environmental Friendliness
Contains no greenhouse gases, GWP < 1
Safety and Reliability
Fully insulated and fully sealed structure; all live parts are enclosed within the gas tank, inaccessible and protected from the operating environment
Application Flexibility
Incoming and outgoing units can share a common gas tank or have independent gas tanks; all functional units can be flexibly configured, with identical cabinet dimensions
Compact Structure
Each functional unit is as narrow as 325 mm
Low Maintenance
Minimal maintenance required; the main components are maintenance-free
Digital Intelligence
Safe Digital digital intelligent solutions enable smart asset health management; distributed distribution automation ensures reliable distribution system management. From equipment to system, meeting the construction requirements of smart grids.
Standardized Solutions
Meets standardized customized solutions, with cabinet types including top-disconnect V units (disconnector and earthing switch on the busbar side), bottom-disconnect V units (disconnector and earthing switch on the cable side), load switch C modules, busbar sectionalizing and coupling cabinets, and PTC cabinets with disconnector and earthing switches, meeting a wider range of customer needs.
