Wuxi Yongda Shu Conductor Co., Ltd. (formerly Wuxi Shu Conductor Factory) is affiliated to Wuxi Yongda Technology Group and is engaged in the research, development, production and sales of mobile power feeding systems.

In 1986, the company developed and introduced DHG plastic conduit-type safe slip connection transmission device under the blank space in China and applied for a national patent. Based on market needs, the company has successively developed DHGJ metal conduit type safety sliding connection transmission device since 1987; DHS, DHHH and DHHT single-pole combined sliding connection transmission device; DHR flexible combined sliding connection transmission device; high voltage resistance, High current DHKS and DHFS rigid-body sliding transmission rails; DHB flexible and integrated sliding transmission devices, cable pulleys, etc. In 2006, the world's first RTG sliding contact wire oil-to-electric power supply project was launched, making outstanding contributions to port energy conservation. The products are sold nationwide and exported to Myanmar, Thailand, Malaysia, Vietnam, Sudan, Brazil, Argentina and other countries. They are widely used in automobiles, energy, customs, electrical appliance production, ports, steel mills, power plants, water plants and other mobile power supply occasions.

In 1992, the company was commissioned by the former Ministry of Machinery to draft and formulate the industry standard for the production and inspection of safety sliding lines JB/T6391-1992, and approved and implemented it with the approval of the State Administration for Technical Supervision, as a guided acceptance standard for the domestic mobile feeding industry. In recent years, the old version of the standard was revised and supplemented by the China Mechanical Industry Federation, and in 2010, the new version of the sliding connection transmission device standard JB/T6391-2010 formulated by the company was promulgated and implemented.

The company has a domestic scientific research institution engaged in the development and process research of mobile feeding systems, and has strong scientific research and development capabilities. At the same time, the company has a marketing network and product supply system throughout the country and even abroad to ensure that customers obtain the company's products, services and information in a very short time.
