RM6-12 Fully Insulated, Fully Enclosed, Air-Insulated Ring Main Unit Equipment
Keywords:
RM6-12 Fully Insulated, Fully Enclosed, Air-Insulated Ring Main Unit Equipment
The RM6-12 fully insulated, fully enclosed, gas-insulated ring main switchgear is a three-phase, 50Hz AC, metal-enclosed switchgear featuring SF6 gas for complete insulation and sealing.
Featuring a modular design, it utilizes primary switching devices such as vacuum circuit breakers, load switches, load switch-fuse combinations, and disconnect switches as functional units, all housed within sealed gas-insulated compartments. The busbars can be freely extended in either direction via busbar connectors, while incoming and outgoing cables are connected using plug-in cable systems. This design ensures protection from environmental factors, delivers high safety, requires no maintenance, and boasts exceptional reliability.
Widely used in industrial and residential ring network distribution systems as well as at the end of power supply, it is particularly suitable for small-scale secondary substations, switchgear rooms in industrial and mining enterprises, urban residential communities, airports, railways, and other facilities.
