Ring Main Unit Market Trends




  • Growing Industrial Infrastructure to Drive Market Growth




Market CAGR for ring main unit is being driven by the rising industrial infrastructure. Increased investment in industrial infrastructure is expected to accelerate the power supply and distribution lines throughout industries and regions. The increased industrialisation has accelerated the establishment of new industrial facilities. Complex electrical substations are required by industries to meet their power needs and minimise mishaps caused by overloading. To maintain voltage variations, switching equipment such as the RMU is required. Because of the rising reliance on electrical machinery in industries, it has become critical to ensure the safe operation of electric supply. As a result, increasing investments in industrial infrastructure drive market growth during the projection period.


Furthermore, consumers' growing environmental consciousness and increased emphasis on lowering carbon emissions will stimulate the creation of renewable energy. The growth of the renewable energy business has prompted governments to build power plants to generate electricity from a variety of renewable resources. The growing reliance on renewable energy resources for power generation can also be attributed to the cheaper capital requirements compared to oil and gas.


The Levelized Cost of Electricity Generation (LCOE) using various energy sources from various world areas was analysed in the IRENA's (International Renewable Energy Agency) Projected Costs of Generating Electricity 2020. Wind energy was discovered to be the least expensive, while coal energy was discovered to be the most expensive. Increased investment in renewable energy sources is predicted to boost distribution utility, necessitating the use of smart switching technology. As a result of these reasons, this market is predicted to expand.


In addition, technological developments are a major trend that is gaining traction in the ring main unit industry. Major players in the ring main unit market are focusing on developing new technical solutions to strengthen their market position. For example, in April 2021, Siemens AG, a German ring main unit manufacturer, introduced the 8DJH 24 switchgear, a totally fluorinated gas-free ring main unit (RMU) for line voltages up to 24 kilovolts (kV) manufactured with vacuum technology. Siemens' new F-gases technology replaces both the SF6 insulating medium and the fluorine-based gas mixture. As a result, the distinctive features of this innovative switchgear reduce the carbon footprint of grid operators. The switchgear is safe and simple to handle, and it is easily recyclable.


Ring Main Unit Market Segment Insights:


Ring Main Unit Type Insights


The Ring Main Unit Market segmentation, based on type includes oil insulated, gas insulated, air insulated, and solid dielectric. Gas-insulated segment dominate the market with a share of 68%, because they are chemically resistant and small, and have outstanding functionality and durability during secondary distribution. Gas insulation is commonly utilised in railway systems, electricity grids, mines, wind farms, and subterranean facilities. Furthermore, gas-insulated RMUs have superior high-temperature endurance and effective load balancing, which are major benefits driving market expansion.


Ring Main Unit Installation Insights


The Ring Main Unit Market segmentation, based on installation, includes indoor and outdoor. The outside segment dominated the market, due to the increased investments in the renewables industry, which would further contribute to an increase in the necessity for outdoor RMUs, to meet the rising energy generation. However, most RMUs are now installed indoors due to their widespread use in industrial and power production applications, which can be attributed to their ease of maintenance, high durability, and compact design.
