Gas-insulated switchgear technology offers significant advantages in terms of immunity to weather conditions, ensuring personal safety, and maintenance-free design. These advantages provide reliable power supply for users and energy suppliers. Gas-insulated switchgear can be used not only in the power transmission and distribution systems of power companies but also in medium-voltage systems in industries such as mining, steel, and papermaking. It is also the preferred choice for special applications such as wind power generation, offshore drilling platforms, and ships.

The new generation of green intelligent ring main units cleverly combines dry air and vacuum breaking technology, applicable to medium-voltage primary and secondary power distribution, contributing to the achievement of "dual carbon" goals. This product features a green and environmentally friendly design, miniaturized construction, and a fully sealed and fully insulated design. All high-voltage energized circuits are sealed within a stainless steel gas chamber, and the maintenance-free design allows for wide application in outdoor switch stations, indoor distribution rooms, and prefabricated substations.

Rated voltage: 12-24KV, rated current: 630A-1250A. While using dry air as the insulating gas, it retains the functions and advantages of traditional SF6 equipment, contributing to the low-carbon and sustainable development of the power grid. Dry air, as an insulating gas, not only has no greenhouse effect but also produces no toxic byproducts during equipment operation; furthermore, there is no need to consider gas recovery at the end of the equipment's lifespan.

The ring main unit's casing consists of independent functional compartments; the main busbar, load switch, and combined electrical unit are all in separate compartments. The gas-filled compartments of the ring main unit are constructed from 3.0mm stainless steel plates using argon arc welding. The load switch and busbar connections are all sealed within SF6 gas.
