A groundbreaking event occurred with the successful implementation of China’s first integrated power generation and storage electric tensioner, as part of the 330kV Weiheyuan transmission line project in Dingxi, Gansu. This innovative electric tensioner signifies a remarkable advancement in power grid construction equipment, ushering in a new era of electrification and sustainability in the industry. The event took place on June 13 in Jinggu town, Kangle county, Linxia Hui autonomous prefecture, Gansu province.
The tensioner holds a pivotal role as a critical mechanical component in power grid construction, working in conjunction with the puller to provide traction and tension for the conductors, thereby enabling the installation of wires. Setting itself apart from traditional hydraulic tensioners, the electric tensioner offers heightened tension control sensitivity at the millisecond level and diminishes tension control deviation to a mere 1 percent, resulting in greater precision in tension control for stringing and a marked improvement in construction efficiency.
Bai Haowei, a member of the research team from the Gansu Electric Power Transmission and Transformation Company, explained, “Our developed electric tensioner generates and efficiently stores electricity during operation, thereby recovering and utilizing traction energy. It operates without the need for fuel or external charging, achieving an integrated cycle of energy generation, storage, and utilization.”
