Nanjing Huashi Electronic Scientific Corporation Limited

Nanjing Huashi Electronic Scientific Corporation Limited (南京华士电子科技股份有限公司), commonly presented as Nanjing Huashi Electronic Technology Co., Ltd. and operating within the Huashi Group (华士集团), is a Chinese technology company headquartered in the Yuhua Economic Development Zone of Nanjing, Jiangsu Province. According to its official website, the Huashi Group was established in 1992 and is positioned as a domestic brand supplier of traction and control systems for the rail-transit industry. The company states that it has repeatedly broken the monopoly of foreign manufacturers in multi-standard urban rail transit and has built its strategy around the localization of core rail traction technology. The company's core competence is high-power power electronics. Its product and solution portfolio covers metro vehicle traction systems, maglev train traction systems, rubber-tyred transit traction systems, digital rail vehicle traction systems, straddle-type monorail traction systems, and intercity/regional vehicle traction systems. Beyond rail transit, Huashi has expanded into electric-drive applications including hydrogen power systems, diesel-electric hybrid systems, and pure-electric power systems for mining machinery decarbonization, as well as diesel locomotive-to-electric conversions. It also provides full-lifecycle maintenance and service solutions, including on-site data monitoring, repair, upgrade and refurbishment, remote support and diagnostics, on-site service, training and consulting, and spare-parts management. Huashi describes itself as a national-level "little giant" specialized and sophisticated enterprise (专精特新小巨人企业) and a high-tech enterprise, and as a strategic partner of the Institute of Electrical Engineering of the Chinese Academy of Sciences, with which it jointly operates a Beijing R&D center. The company reports nearly one hundred R&D personnel, with core team members each having more than ten years of experience in electric-drive and power-system integration and design. Its stated vision is to become an overall solution supplier of high-power power-electronics technology plus new-energy power systems. In 2019 the group expanded through the establishment of Zhongke Huashi Electric Technology Nanjing Co., Ltd. and the acquisition of Guangdong Nanao Transportation Equipment Co., Ltd. Zhongke Huashi focuses on high-power engineering-machinery assemblies and has formed strategic cooperation with leading enterprises such as North Hauler (北方股份) and Gemac Engineering Machinery (金鹰重工). Guangdong Nanao, based in the Pearl River Delta, provides metro and high-speed rail inspection and repair services, including for China MTR and South China markets. The company maintains 15 national offices across six major regions of China and advertises one-hour rapid response for its service network.

Nanjing Huashi Electronic Scientific Corporation Limited traces its origins to the Huashi Group, which was established in 1992 and headquartered in Nanjing, Jiangsu Province, China. From its early years the company pursued a technology-driven strategy centered on the localization of high-power power electronics and rail-transit traction technology. According to its official website, Huashi positioned itself as a domestic brand supplier of traction and control systems for the rail-transit industry, seeking differentiated development while repeatedly breaking the monopoly of foreign manufacturers in the multi-standard urban rail transit market. Over roughly three decades the company built up expertise in high-power power electronics and expanded its product portfolio across multiple rail-transit modes. Its solutions now include traction systems for metro vehicles, maglev trains, rubber-tyred transit, digital rail vehicles, straddle-type monorail, and intercity/regional vehicles. The company also developed full-lifecycle maintenance and service capabilities, covering on-site data monitoring, repair, upgrade and refurbishment, remote support and diagnostics, on-site service, training and consulting, and spare-parts management. In 2019 the group took two significant expansion steps: it established Zhongke Huashi Electric Technology Nanjing Co., Ltd. and acquired Guangdong Nanao Transportation Equipment Co., Ltd. Zhongke Huashi focuses on high-power engineering-machinery assemblies and has formed strategic cooperation with leading enterprises such as North Hauler (北方股份) and Gemac Engineering Machinery (金鹰重工). Guangdong Nanao, leveraging its location in the Pearl River Delta, provides metro and high-speed rail inspection and repair services, including for China MTR and South China markets, and has shown steady business growth. More recently, Huashi has extended its power-electronics expertise into new-energy and decarbonization applications. Its product and solution pages list hydrogen power systems, diesel-electric hybrid systems, and pure-electric power systems for mining machinery decarbonization, as well as diesel locomotive-to-electric conversion solutions. In July 2025 the group announced its assistance in the successful delivery of a DGM-20H rail grinding machine to Guangzhou Metro, and in December 2024 it reported progress on a diesel-electric hybrid mining truck retrofit solution. The company describes itself as a national-level specialized and sophisticated "little giant" enterprise and a high-tech enterprise, and as a strategic partner of the Institute of Electrical Engineering of the Chinese Academy of Sciences, with which it jointly operates a Beijing R&D center. It reports nearly one hundred R&D personnel and maintains 15 national offices across six major regions of China, offering one-hour rapid response service.
