Overall Overview of the Medium-Voltage Eco-Friendly Gas RMU Market Size
In 2025, investment by the State Grid continues to scale up. The State Grid and China Southern Power Grid have a combined investment of 825 billion RMB, driving the upgrade of the entire chain from equipment manufacturing to the application of smart technologies. Large-scale renewal and transformation of distribution networks, new energy supporting projects, and OEPC export projects are filling the gap caused by the decline in the residential power distribution market, and are gradually developing rapidly.
In 2025, the proportion of eco-friendly gas switchgears used continues to grow significantly, primarily due to large-scale procurement by distribution network companies. The State Grid is basically purchasing eco-friendly switchgears. Driven by environmental protection policies, distribution network companies such as the State Grid, provincial grids, and power supply bureaus are continuously increasing their procurement of eco-friendly gas RMUs to replace SF6 switchgear products.
Currently, all manufacturers are promoting eco-friendly products. Foreign brands are focusing on power supply bureau orders in regions such as Jiangsu, Zhejiang, and Shanghai, as well as Beijing, Tianjin, and Xiongan in Hebei; domestic brands are focusing on centralized procurement projects of the State Grid and provincial grids.

Competitive Landscape of the Medium-Voltage Eco-Friendly Gas RMU Market
Introduction to the Eco-Friendly Gas RMU Market:
Driven by the dual pull of green centralized procurement by the two major domestic grids and overseas exports, the growth of the eco-friendly RMU market is accelerating. The State Grid and China Southern Power Grid continue to increase the proportion of SF6-free products in their bidding, and new energy supporting projects further expand domestic demand; overseas low-carbon infrastructure construction drives a steady increase in product exports.
Eaton Corporation relies on its high bid-winning rate through direct brand participation in the two major grid markets to secure its position in the first tier; Schneider Electric and ABB participate in the grid market relying on their technology and mature gas compartment cooperation channels. They also benefit from the strong pull of their performance in exporting to overseas mid-to-high-end markets by supporting the new energy industry, sharing the first tier with NARI Group;
Siemens, XJ Electric, Pinggao, and other brands are in the second tier; numerous brands such as Shuangjie, Kelin Electric, Beijing Kerui, Beijing Hezong, Tianan Intelligent, Chint, Baiyun Electric, Ormazabal, Xiamen Huadian, Clou Dongzi, Deyun Electric, and Anhui Longbo have begun to increase their R&D investment in eco-friendly products, successively launching eco-friendly gas-insulated RMU products. Compared to 2024, the relevant revenue of each enterprise is continuously increasing.
Manufacturers' 24kV and 40.5kV high-voltage eco-friendly RMU products have been continuously implemented and mass-produced in the past two years; Schneider Electric has completed the release of 12~40.5kV products and completed the national-level appraisal of product technology in the Chinese market; ABB launched the 24kV dry air eco-friendly RMU in October 2025, completing the 12~40.5kV SF₆-free product line; Siemens' 12kV/24kV clean air eco-friendly RMUs are already in mature mass production, and will launch 40.5kV eco-friendly RMUs in 2026; Eaton Corporation's 40.5kV eco-friendly RMU products are also under active R&D and testing, and are expected to be released soon.
