The ring main unit market size has grown strongly in recent years. It will grow from $2.52 billion in 2025 to $2.7 billion in 2026 at a compound annual growth rate (CAGR) of 7%. The growth in the historic period can be attributed to growth of urban electrification projects, increasing deployment of mv-lv distribution networks, adoption of sf6 and air-insulated switchgear, expansion of industrial and utility installations, modernization of distribution infrastructure.
The ring main unit market size is expected to see strong growth in the next few years. It will grow to $3.53 billion in 2030 at a compound annual growth rate (CAGR) of 7%. The growth in the forecast period can be attributed to rising investment in smart grid rollouts, increasing demand for compact and safe switchgear, growth in renewable energy-based distribution networks, rising adoption of digital protection relays, expansion of urban and commercial load centers. Major trends in the forecast period include integration of smart grid-connected rmus, expansion of sustainable medium-voltage distribution solutions, advancement of intelligent switchgear manufacturing, development of digital monitoring and protection systems, adoption of automated distribution management platforms.
The increasing demand for electricity is expected to drive the growth of the ring main unit market. Electricity refers to a form of energy used to power machinery and equipment that produce light or heat. As electricity demand rises, ring main units are required for various applications, including connecting different types of switches, supplying power to distribution transformers, and supporting other essential operations. For example, in September 2024, according to the International Energy Agency (IEA), a France-based agency, total net electricity production in June 2024 increased to 902.8 TWh, representing a 5.4% rise compared to the same period the previous year. Therefore, the growing demand for electricity is fueling the expansion of the ring main unit market.
Major companies in the ring main unit market are focusing on developing non-SF6 ring main units to reduce environmental impact, meet stricter greenhouse gas emission regulations, and promote sustainable power distribution solutions. Non-SF6 ring main units (RMUs) are medium-voltage electrical switchgear systems that do not use sulfur hexafluoride (SF6) gas for insulation or arc-quenching. For instance, in April 2024, Lucy Electric Ltd., a UK-based company, launched EcoTech, a non-SF6 ring main unit. EcoTech replaces SF6 with synthetic air (a nitrogen-oxygen mixture), addressing environmental concerns associated with greenhouse gas emissions. It also features an embedded control unit and standard remote-control capabilities, enhancing operational efficiency and enabling improved monitoring and management of energy distribution systems.
In July 2023, AcBel Polytech Inc., a Taiwan-based company, acquired MANN ABB Ltd. for $505 million. This acquisition allows AcBel Polytech to expand its portfolio by integrating ABB's expertise in providing ring main units (RMUs). ABB Ltd. is a Switzerland-based company known for offering RMU solutions.

A ring main unit (RMU) is a pre-assembled set of switchgear enclosed in metal, commonly utilized at the connection points within a ring-type distribution network. It features two switches that connect both ends of the load to the primary conductors and incorporates a fusible switch or circuit breaker functioning as a tee-off for supplying medium voltage to low voltage distribution transformers (MV to LV).
The primary types of ring main units include gas-insulated, oil-insulated, air-insulated, solid di-electric, and other variants. Gas-insulated units consist of components where active parts carrying high voltage potential are situated within aluminum alloy pipes, held in place by epoxy resin insulators. Component types typically encompass self-powered electronic relays, switchgear, and fuses. These units operate at various voltage levels including low, medium, and high voltages and are designed for both indoor and outdoor installations. They find extensive use in industrial, commercial, and residential distribution applications.Asia-Pacific was the largest region in the ring main unit market share in 2025 and is expected to be the fastest-growing region in the forecast period.
