Product Description
High Voltage Switchgear 12kv Solid Insulated Ring Main Unit RMU For Indoor with SF6 free
Since the 1990s, with accelerating urbanization and continual improvement of power supply reliability, overhead lines have been replaced by buried cables and indoor switching stations by outdoor switching stations. The small, touchable, all-insulated, flood-control, and maintenance-free ring main units have rapidly developed and are widely used in various locations requiring reliable power distribution systems, including urban commercial centers, industrial districts, airports, electrified railways, and expressways. These units can be used singly indoors or outdoors, as well as integrated into prefabricated substations.
The MKS series solid-insulated ring main units incorporate advanced production facilities and manufacturing technology, enabling localized production that significantly reduces manufacturing costs and shortens delivery periods. This product line has received favorable responses since its launch.
