Construction Technology and Apparatus for 6 ×900/75mm2 Large Cross-Section Overhead Conductor
In recent years,6 × JL/G2A-900/75 large cross-section steel core aluminum stranded wire has been applied in the projects of UHV DC lines in order to improve the transmission line capacity,but construction experience of large cross-section wire is relatively insufficient.Through the research and development of the relevant construction technology and apparatuses (such as the large wheel-diameter tensioner,high-strength lightweigh insulated pulley,net connector,wire line card device,traction rope,etc.),the problems in installing six-division 900/75 mm2 wire were effectively solved,and the realization of the construction quality and safety goals was ensured.
