SafeRing / SafePlus Air Dry Air Insulated Main Main Unit and Compact Switchgear are environmentally friendly gas-insulated main unit units and switchgear launched by ABB, which have the characteristics of good environmental performance, high reliability and safety performance, compact structure and maintenance-free. Dry air is used as the insulating medium, dry air is a commonly used industrial gas, and the customer does not need to maintain and recycle. Leaks occur during the operation of the equipment and do not have any impact on the environment.

  SafeRing / SafePlus Air largely inherits the mature production process and operation experience of the existing gas-insulated switchgear, which can ensure the stable and reliable operation of the product to a large extent. It has good environmental adaptability and can be applied to industrial environments such as sandstorm, humidity and pollution; Multiple functional units can be sealed in the same chamber, resulting in a more compact structure and less installation effort on site.

Eco-friendliness

Greenhouse gas-free, GWP=0

Safety and reliability

Fully insulated and fully sealed structure, all live parts are sealed in the gas box, inaccessible, and also free from the operating environment

Flexible application

Each inlet and outlet unit can be a common gas box, but also an independent air box; All functional units can be flexibly configured and have the same cabinet size

Compact structure

Each functional unit is as small as 325 mm wide 

Less maintenance

Less maintenance, the main part is maintenance-free

Digital intelligence

Safe Digital's digital intelligence solution for smart asset health management; Distributed distribution automation for reliable distribution system management. From equipment to systems, to meet the construction needs of smart grids.

Standardized protocols

To meet the standardized design requirements of SGCC, the cabinet type includes the isolated vacuum circuit breaker cabinet on the V cabinet (the isolation grounding switch is on the bus side), the isolated vacuum circuit breaker cabinet under the V cabinet (the isolation grounding switch is on the cable side), and the PTC cabinet with the isolation grounding switch in the PTC cabinet to meet the needs of more users.
