Global Ring Main Unit Market: Overview

Ring Main Unit (RMU) is a sealed, enclosed, and compact type of switchgear that is been used for medium voltage power distribution. RMU in itself is complete switchgear consisting of a metering device, protection device, and assembly of all required switching devices. As RMU is a complete package and only requires cable connection and installation, it is widely used in the distribution system.

Global Ring Main Unit Market: Growth Factors

The global ring main unit market is growing at a significant rate. Major factors that are augmenting the growth of the global market include industrialization growing at a speedy rate, increase in the automation process, and expanding use of RMU in distribution utilities. Ring main units are widely used to control the circuit to switch functions, protect the circuit from overload, short-circuit current fault, & ground-fault current and isolate the faulty equipment from the rest of the circuit. The ring main units are widely adopted by several industries and the transportation sector as it reduces the maintenance as they are free to maintain due to incorporation of self-test features, provides better tolerance to harsh environments, improved protection, help to better coordinate protection with other protective equipment including those with low voltage & medium voltage, possess feature-rich compact design, save money & time, and offers efficiency, reliability, connectivity & safety. In addition to this, RMU can integrate with the distribution management system and build Smart Grid solutions which are also adding up to the adoption of the ring main unit.

This is propelling the growth of the global ring main unit market. Additionally, the growing demand from various infrastructure including residential, hospitals, and hotels & resorts is also boosting the growth of the global market. Moreover, factors such as growing renewable energy installations, increasing electricity generation projects, and underground cable networking are fostering the overall market growth. Furthermore, the emergence of smart RMU enabling faster power restoration due to decentralized schemes and compliance with the latest cyber security standards will have opportunities that will significantly boost the global ring main unit market during the forecast period. However, similar to the radial power distribution system, the ring distribution system cannot be expanded, and the ring main unit is expensive as compared to other switchgear. This may restrain the growth of the global ring main unit market.

The global ring main unit market is adversely hit by the Covid-19 pandemic. The manufacturers of ring main units have to close all their operations due to strict rules of complete lockdown and restriction on movements implemented in several countries across the world to control the rapid spread of the infection. With ease in the restrictions, the manufacturers also have to face multifaceted challenges caused by a disruption in the supply chain and restriction on personnel. Drop in production coupled with the decrease in demand from its end-users hampered the market growth during the pandemic.

Recent Developments:

• In February 2025, Schneider Electric secured a major contract with Tata Power Company Limited in Mumbai for the deployment of 11 kV SF6-free Ring Main Units. The project will use Schneider Electric’s RM AirSeT SF6-free technology to advance sustainable energy management and automation solutions.
• In July 2024, the Saudi Electricity Company (SEC), in partnership with Alfanar, announced the successful installation and operation of the first locally manufactured, eco-friendly Smart Ring Main Unit in the Middle East. The unit has successfully passed all quality and safety tests conducted by a leading global laboratory specializing in electrical equipment.
• In March 2024, Lucy Electric introduced EcoTec, the UK’s first ring main unit (RMU) designed for medium-voltage networks that operates without using Sulphur hexafluoride (SF6).
