Overall Overview of the Medium Voltage GIS Switchgear Market Size
In 2025, the overall GIS market size is approximately RMB 5.5 billion, representing a year-on-year growth of about 3%. This growth is primarily driven by the rail transit industry, while the industrial and petrochemical sectors maintain stable growth in their basic volume:
Metro industry market demand is increasing. Deferred projects from 2024 are being ordered successively in 2025, leading to rapid performance growth for manufacturers such as Schneider, ABB, and Daqo in the metro sector. Key metro projects in 2025 include Phase I of Metro Line 5 in Shijiazhuang, Phase I of Metro Line 4 in Shijiazhuang, Phase II (Northern Extension) of Metro Line 13 in Shenzhen, the Shenzhen-Dongguan Intercity Railway in the Guangdong-Hong Kong-Macao Greater Bay Area Shenzhen Metropolitan Circle, Phase I of Metro Line 15 in Hangzhou, and Phase IV of Xiamen Rail Transit (Houxi to Xiang'an Airport Section), among others;
The oil and petrochemical market is growing steadily. Related refining and chemical projects from SEI, Huanqiu, and Tianchen in the Chinese market are entering the main delivery phase. They have recently achieved a breakthrough by securing large-scale refining and chemical plant orders in the Middle East market. It is expected that overall related demand will remain stable during the 15th Five-Year Plan period;
Overseas market demand is growing. As carbon tariffs are continuously implemented in high-end overseas markets, supporting opportunities for large-scale overseas energy storage and overseas wind power projects are becoming prominent. Companies such as TGOOD, Daqo Electric, and Jinpan Smart Technology are deeply participating in the overseas market alongside Goldwind, Sungrow, and others.

2015/2025/2030E Medium Voltage GIS Switchgear Market Size -- Segmentation by Industry
Industrial projects: Primarily applied in the heavy industry sector, they are widely used in the highly loaded and stringent petrochemical and steel industries.
Infrastructure industry: GIS switchgear is widely used in the metro industry, primarily applied in 40.5kV standard switchgear drives. This is followed by the railway industry, mainly in high-speed rail projects, where 27.5kV products are used in the "four electrical systems" (power supply, signaling, communication, and electrification) of high-speed rail traction substations. Additionally, some 12kV GIS products are used in 12kV power distribution stations for high-speed rail.
Power industry: Primarily used in urban power grids, mainly for 12kV distribution network applications. Secondly, some GIS products are also used in the voltage step-up stage for offshore wind power.
