Overall Overview of the Medium Voltage Switchgear Market Size
In 2025, the overall market size of the domestic medium voltage switchgear market reached 47.1 billion RMB, a year-on-year growth of 2%. The market remains sluggish with a slowing growth rate, and is expected to maintain a growth rate of 5% in the future. In 2025, the overall market continued to be affected by the economic environment and fell short of expectations, with market growth driven by new industry opportunities.
In 2025, the performance of AIS, GIS, and RMU maintained steady growth, mainly due to the following reasons:
1. AIS switchgear growth was mainly driven by increased investment and construction in key industries. For example, market demand in industries such as data centers, petroleum, chemical new materials, nuclear power, and the automotive supply chain continued to grow rapidly, boosting performance;
2. GIS switchgear growth stabilized and recovered, mainly driven by the continuous recovery of the subway industry, with many previously delayed projects resuming construction; overseas new energy supporting demand provided a significant boost; and urban grid transformation drove the demand for eco-friendly GIS;
3. RMU market growth was mainly driven by the substantial replacement of SF6 switchgear with eco-friendly switchgear products. However, prices have dropped significantly. In the future, orders from overseas new energy supporting projects will fill the gap caused by the decline in residential power distribution.
Medium Voltage Switchgear Market Size -- Segmentation by Voltage Level
In terms of proportion, medium voltage switchgear products are mainly dominated by 12kV, accounting for 80%, with year-on-year growth primarily in data centers, chemical new materials, and export supporting industries. This is followed by 40.5kV complete switchgear, which holds a 17% market share, driven by overseas export supporting demand. The 24kV and 27.5kV segments account for about 3%, mainly applied in GIS switchgear for subways and railways, while the rest are driven by grid demand and applications in industrial parks in some regions of East and South China.
From the perspective of voltage levels:
1. 12kV medium voltage switchgear: AIS switchgear is widely used in various industrial sectors, distribution networks, power generation, and infrastructure construction. GIS switchgear is mainly used in 12kV substations of petrochemical plants and in grid bidding and procurement. RMU is primarily used in distribution networks and residential power distribution projects. In 2025, the real estate residential distribution industry continued to decline, and applications in the power access links of public and commercial buildings remained relatively low, focusing mainly on main grid centralized procurement projects;
2. 24kV medium voltage switchgear: AIS switchgear products have limited applications, mainly used in some joint-venture industrial park projects in East and South China, as well as in some 24kV distribution network systems. GIS switchgear products are dedicated to railways, especially for supporting applications in the 27.5kV traction systems of the high-speed rail industry. RMU has fewer applications in projects;
3. 40.5kV medium voltage switchgear: AIS switchgear products are mainly applied in industrial industries. GIS switchgear products are widely used, primarily in 40.5kV transformation systems for subways, petroleum, and petrochemicals. RMU growth is driven by centralized photovoltaics, large-scale energy storage, and enterprises going global, with its proportion continuing to increase year-on-year.
2015/2025/2030E Medium Voltage Switchgear Market Size -- Segmentation by Industry
● Industrial Projects: Medium voltage switchgear is widely used in industrial projects, primarily in heavy industries. It is extensively used in the high-load and highly demanding petrochemical industry, with good future development prospects.
● Power Generation & Grid: The development trend of medium voltage switchgear in the power generation and grid industry remains stable. Among these, the demand for eco-friendly RMU driven by environmental policies is growing rapidly, which also includes overseas export supporting, overseas grid upgrades, and thermal power.
● Construction: Future demand in the construction industry will continue to decline, mainly due to the current downturn in the real estate industry, resulting in less demand for the development of civil residential and commercial buildings.
● Infrastructure: In infrastructure construction, growth is driven by the substantial demand from the data center industry. The development of big data, AI, and cloud computing has boosted data center construction. This is followed by the continuous recovery of the subway market, with steady demand growth.
