Overall Overview of the Medium Voltage Switchgear Market Size
From 2015 to 2025, China's medium voltage switchgear market grew from 43.62 billion RMB to 47.09 billion RMB, with a ten-year CAGR of only about 0.8%. The market has generally remained in a state of low-speed fluctuation. During this period, affected by the pacing of power grid investments, the boom and bust of industrial projects, and the downturn in the real estate chain, the market size experienced multiple phased declines. After 2025, the medium voltage switchgear market is expected to enter a more stable phase of recovery and growth. From 2025 to 2030, the market size is projected to increase from 47.09 billion RMB to 55.05 billion RMB, with a CAGR of approximately 3.2%, significantly higher than the overall growth rate of the medium and low voltage switchgear market. This growth is primarily driven by the power grid upgrades, renewable energy grid integration, energy storage, and power electronics integration boosting medium voltage distribution systems' demand.
For switchgear manufacturers, medium voltage switchgear represents a crucial strategic direction to transition from low-price competition to high technology, high qualifications, and high project thresholds. It imposes higher requirements on corporate qualifications, testing capabilities, engineering experience, brand endorsement, and safety reliability. Meanwhile, the customer base is increasingly concentrated in power grids, energy sectors, industrial projects, and large-scale infrastructure.
Market Size Segmentation of Medium Voltage Switchgear
Primary equipment remains the core product of the medium voltage switchgear market, with a market size of approximately 35.53 billion RMB in 2025, accounting for 75.5%. Primary equipment is mainly applied in scenarios such as power grids & power generation, industrial projects, buildings, and infrastructure. In the future, driven by power grid investments, renewable energy grid integration, industrial project supporting facilities, and infrastructure construction such as rail transit and data centers, the demand will still have a foundation for growth; however, the construction sector remains in an adjustment phase, and the limited release of demand from traditional industries such as metallurgy, cement, and ceramics will impose certain constraints on the overall growth rate.
Secondary equipment is primarily applied in scenarios such as urban power grids, building power distribution, and control and protection. Future growth will mainly come from urban distribution network upgrades, distributed energy integration, supporting facilities for NEV charging and battery swapping, and the renovation of existing buildings; the impact of new real estate projects remains weak, and the demand for building power distribution will still focus on the renovation of existing stock and localized release, resulting in a relatively moderate pace of market recovery.
