SF6 Insulated Ring Main Unit (RMU) (sulfur hexafluoride gas insulated switchgear)
SF6 gas cabinet (sulfur hexafluoride gas insulated switchgear) is a high-voltage electrical equipment that uses SF6 gas as an insulating and arc-extinguishing medium Core Advantages: Miniaturization: The high insulation of SF6 makes the equipment volume more than 50% smaller than that of air-insulated cabinets. High reliability: Fully enclosed structure, not affected by the environment (humidity, dirt, altitude). Maintenance-free: SF6 gas has high stability and the contacts are almost non-oxidized in an inert environment. Long life: The design life can reach more than 30 years. Safety: No fire risk, low operating noise.
Application Areas: Substation: incoming, outgoing and connecting lines of medium and high voltage distribution systems. Industrial electricity: Harsh environments such as mining, metallurgy, and chemical industry. Urban power grid: Places with high space requirements such as subways, airports, and data centers. Renewable energy: Boosting and grid connection of wind farms and photovoltaic power stations.
