Applications
Power Distribution for Urban & Industrial Networks
Types
Gas-Insulated RMU (SF6 RMU)
Uses SF6 gas as insulation, ensuring superior protection and longevity.
Compact and sealed, making it maintenance-free.
Widely used in industrial power distribution and urban networks.
Air-Insulated RMU (AIS RMU)
Uses air as an insulating medium, making it environmentally friendly.
Slightly larger than SF6 RMU but cost-effective.
Used in industrial plants and substations.
Motorized & SCADA-Enabled RMU
Equipped with motorized mechanisms for remote operation.
Can be integrated with SCADA systems for real-time monitoring and automation.
Used in smart grids, metro stations, and high-demand power networks.
Outdoor & Indoor RMU
Outdoor RMU: Weatherproof, designed for harsh environmental conditions.
Indoor RMU: Installed within buildings, substations, and control rooms.
