An Atmospheric Pressure Sealed Nature-Air Insulated Ring Main Unit (ASNA RMU) is a power distribution unit where the main electrical components are housed in a sealed cabinet, using air at atmospheric pressure as the primary medium of insulation. The design of this switchgear ensures a leak-proof, fully insulated and low maintenance operation, with key components like the vacuum interrupters, load break switches, and bus-bars enclosed safely. With their fully enclosed and insulated construction, RMUs minimize the risk of electrical faults, providing enhanced safety in environments for industrial, commercial, and residential applications where reliability and protection are critical. With over 50,000 units operating worldwide for over a decade with proven safe, stable and fault-free performance, this power distribution unit works without SF6, complying with the international trend. SF6-free switchgear leads the development of sustainable RMU technology.
