中联重科新能源牵张设备首次应用

Core Viewpoint - The successful application of Zhonglian Heavy Industry's self-developed new energy tensioning equipment marks a significant leap for China from following to leading in the field of overhead transmission line construction equipment [1][3]. Group 1: Project Overview - The project spans a total length of 12.31 kilometers, starting from the 220kV Hengdian Village substation to the 110kV Fenglin substation, with the construction segment measuring 1.64 kilometers [3]. - The project aims to optimize the network structure in the northwest region of Liling, significantly enhancing power supply reliability [3]. Group 2: Equipment Features - The new energy tensioning equipment replaces traditional fuel-powered systems with an electric drive system, achieving zero emissions and pollution during the construction process [3]. - The energy-efficient tensioning machine can recover traction energy, ensuring self-sufficient battery energy and allowing surplus energy to be shared among devices or used for powering drone systems and night lighting [3]. Group 3: Performance and Efficiency - The new energy tensioning machine employs an "electric drive + range extender" solution, achieving over 50% energy savings compared to traditional fuel tensioning machines [5]. - In practical applications, the equipment operates at a noise level of only 78dB(A), representing a noise reduction of 20% to 30% compared to previous models [5]. - The direct drive connection between the motor and the tension wheel improves operational efficiency by over 10%, while the intelligent control platform enhances line laying accuracy by 30% and supports millisecond-level response for autonomous switching [5]. Group 4: Industry Impact - Zhonglian Heavy Industry continues to lead the industry transformation towards intelligent, digital, and green innovations, with the successful application of the new energy tensioning equipment being a key practice in promoting mechanization and high-quality development in power grid construction [5]. - The company has also developed four sets of new energy tensioning equipment suitable for 550kV small lines and below 220kV grids, which will be delivered to customers soon [5].
