About Ring Main Unit (RMU)

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. RMUs have found extensive application in industrial, commercial and utility power systems.

Types of Ring Main Unit (RMU)

As Ring Main Unit (RMU) Suppliers in Chakan, we offer gas-insulated and vacuum circuit breaker-based RMU systems.

  • 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.
  • 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.
  • 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) Traders in Chakan, our units offer high reliability and secure operation under varying load conditions.

  • 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.
  • 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.
  • 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.

FAQ

The primary function of a Ring Main Unit (RMU) is to provide a reliable way to connect, disconnect, and protect power distribution networks, ensuring continuous supply even if a fault occurs in one part of the ring.

AIS (Air-Insulated) uses air for insulation and requires more space, while GIS (Gas-Insulated) uses SF6 gas, allowing for a much more compact, sealed, and low-maintenance unit.

Yes, we supply Outdoor Ring Main Units with high IP ratings (like IP54 or IP65) that are specifically designed to withstand rain, dust, and environmental exposure.
