About Ring Main Unit (RMU)
RMUs have found extensive application in industrial, commercial and utility power systems. RMU is small size enclosed medium voltage switch equipment employed to protect, switch, and distribute electrical power in a safe way. It assures continued flow of power by isolating faults without discontinuity in ring type distribution networks.
Types of Ring Main Unit (RMU)
As Ring Main Unit (RMU) Suppliers in Mumbai, we offer gas-insulated and vacuum circuit breaker-based RMU systems.
Gas-Insulated RMU (GIS): It consists of SF 6 gas as an insulating media, and on this basis we are able to present a reduced size sealed and very reliable unit. Gas-Insulated RMU is appropriate in the tight indoor or exterior space in installations that require less than maintenance. It is also available as a Lucy Ring Main Unit for specialized industrial applications.
Air-Insulated RMU (AIS): It is air based and, therefore, an easy to access and inexpensive solution. Air-Insulated RMU is normally used in controlled conditions where space is not problematic, and regular maintenance can be easily controlled. We also supply Outdoor Ring Main Unit options for exposed environments.
Solid-Insulated RMU: It applies solid dielectric insulation allowing us to offer a gas free and environmentally friendly solution. Solid-Insulated RMU is highly appropriate under harsh conditions, and therefore it is very safe, durable, and has a long life cycle.

Benefits of Ring Main Unit (RMU)
As Ring Main Unit (RMU) Distributors in Mumbai, our units offer high reliability and secure operation under varying load conditions.
Reliable Power Continuity: RMUs are suited to ring distribution systems and they enable the flow of power through an alternate source during faults. This guarantees minimal down-time and continuous power.
Compact & Space-Saving Design: RMUs are compact, metal-enclosed, which makes them suitable to be placed in urban areas and in places with limited space without affecting the performance.
Improved Safety and System Security: To ensure safe operation, RMUs provide the protection of short circuits, overloads and earth faults by using load break switches, fuses or circuit breakers.
Low Maintenance and Cost Efficiency: RMUs have a shorter payback period with factory assembled and sealed parts that save time and minimise the operating cost and regular maintenance.
Intelligent Monitoring & control: The recent RMUs have remote monitoring, fault indication, and automation capabilities that allow them to regulate the system efficiently and interconnect with smart grid networks.
Applications of Ring Main Unit (RMU)
As Ring Main Unit (RMU) Dealers in Mumbai, our units are widely used in substations, industrial plants, and commercial complexes.
Urban Power Distribution Networks: ABB Ring Main Unit in Mumbai are common in underground cable networks in cities which are connected to medium-voltage distribution to provide a reliable and continuous power supply.
Residential and Commercial Infrastructure: They are fitted in shopping centres, hospitals, air terminals, information technology parks and office skyscrapers to ensure relay-dependent and dependable electrical supply.
Industrial Facilities: RMUs serve manufacturing plants and industrial units where stable power and operating security is tantamount to continuous production.
Renewable Energy installations: RMUs are widely employed in solar parks and wind farms; they are useful in controlling power collection, protection, and grid connectivity.
Harsh and Demanding Environments: RMUs with solid insulations can be used in harsh environments like mining, coastal, and oil and gas facilities, which are very durable and safe.
