Environmentally Friendly Gas-Insulated Ring Main Unit Equipment
The UN0-12, 24/630-25kA environmentally friendly gas-insulated ring main unit is a fully sealed and fully insulated ring main unit that employs advanced vacuum interrupter technology. From the design perspective, it meets environmental requirements by being oil-free and SF6-free. All conductive parts inside the switchgear are housed in a sealed stainless steel enclosure, with dry air serving as the primary insulating medium within the enclosure. The main switch uses a vacuum arc-extinguishing system, while the isolating switch features a three-position structure. The enclosure boasts an IP67 protection rating, making it immune to the effects of condensation, frost, salt spray, pollution, corrosion, ultraviolet radiation, and other similar factors.
