Urban Power Distribution Development
With accelerating urbanization and rising demands for power reliability, overhead lines in cities are increasingly being replaced by underground cable systems. Centralized indoor switchgear is gradually giving way to distributed outdoor ring main units (RMUs).
Advantages of SF6 Gas-Insulated RMUs
SF6 gas-insulated RMUs are widely adopted in high-reliability distribution systems—such as commercial centers, industrial zones, airports, electrified railways, subways, and highways—due to their:
-
Immunity to condensation, pollution, high altitudes, small animals, and chemicals
-
Compact design
-
Maintenance-free operation
They are suitable for both indoor and outdoor use and can also be integrated into prefabricated substations.
