Why Does the Air-insulated Segment Dominate the Ring Main Unit Market?

Air-insulated segment is expected to hold 37.5% of the global ring main unit market share in 2026, can largely be attributed to its inherent advantages relating to cost, operational efficiency, and reliability. Air-insulated RMUs use air as the insulating material between their electrical components which drastically reduces the cost of manufacturing and installation of such RMUs as opposed to other types of insulated accessible like gas-insulated-RMU and solid dielectric-RMU. This low cost has contributed to air-insulated RMUs being of particular interest to utilities and infrastructure developers who need to trade performance and budget limitations.

The other cause is the relative ease of maintenance and repair of air-insulated units. This means that any routine inspection and servicing require neither special equipment nor special solid substance handling procedures because it does not require any specialized gases or complex solid materials. This saves on operational cost and down time during the life cycle of the equipment, makes the segments more appealing both in urban and rural distribution networks.

Why is the Indoor Segment Dominating the Global Ring Main Unit Market?

The indoor segment is projected to hold 62.6% of the ring main unit market share in 2026, because of its suitability for growing urban and industrial power distribution environments. As urbanization continues to accelerate, cities become denser, and it is essential to maximize the use of space and make power distribution systems safe. To meet these needs, Indoor RMUs are designed to fit into the building structures, substations, and industrial setups with minimal exposure to the external environment and minimal physical space of electrical devices.

It is also very useful in installation within the interior. Storing the RMUs in controlled condition protects them against the harsh weather conditions of moisture, dust and extreme changes in temperature that impact negatively on the equipment life and performance. This leads to greater reliability and reduced maintenance rates, which are important in large urban grids, where a failure may affect a large number of people and the most important economic processes.

Up to 15 kV Segment Dominates the Global Ring Main Unit Market

Up to 15 kV segment is set to capture 46.7% of the market share in 2026, due to its widespread relevance in low to medium voltage power distribution systems. This is significantly important because this voltage range is the standard operating point of most urban and rural electricity distribution systems, which supplies power straight to domestic, business and light industries.

The presence of distribution networks working within the range of the 15 kV category is one of the main reasons why the category is so dominant in the world. This range of RMUs is mainly used by electrical utilities and grid operators to provide safe and reliable switching, protection and sectionalizing functions. At this voltage, which is critical to continuity of supply and minimization of the effects of outage, the RMUs are effective in facilitating grid segmentation and fault isolation.
