High Voltage Switchgear 12kv Solid Insulated Ring Main Unit RMU For Indoor with SF6 free
Since 1 990s, with the accelerating progress of urbanization and continual improvement of power supply reliability,theoverhead line is replacing by buried cable and indoor switching station replacing by outdoor switching station. The smal.touchable, allinsulated, flood-control, and maintenance-free ring main units are rapidly developed and widely used in differenplaces with reliable power distribution system, such as the urban commercial center, industrial concentration district, airport.electrified rallwav and expresswav etct can be single used indoor and outdoor, as well as be integrated in prefabricatecsubstation.
MKS series solid-insulated ring main units comprehensively introduces advanced production faclity and manufacturingtechnology, implementing localized production, greatly reducing the manufacturing costs, shortening delivery period, and itreceives a favorable respnse after the launch.
