Fully Insulated Sealed Gas-filled Ring Main Switchgear

  Product Introduction：     Ring Main Unit (RMU) is a kind of compact and sealed medium-voltage switchgear, serving as a key node in the distribution network.     It acts as the core unit to connect ring main power supply lines and distribute electric power outward.     It's core working principle is that multiple RMUs are connected to form a ring network, which provides dual power supply reliability for each power consumption point. When a fault occurs in any section of the ring network, power can be supplied continuously from the other side of the ring, greatly reducing the power outage scope and improving power supply reliability.   Classification Method: By Insulating Medium Gas Insulated (SF₆) Most commonly used. It adopts SF₆ gas for insulation and arc extinction, featuring fully sealed and fully insulated structure with strong environmental adaptability. Solid Insulation The live parts are encapsulated with solid materials such as epoxy resin. It features environmen…
