Abstract: Aluminum conductor composite core (ACCC), as a novel energy-saving capacity-enhancement conductor, presents new challenges for live-line working, particularly as conventional lifting tools are prone to damaging the conductor. A universal 4-bundle and 6-bundle conductor lifter tailored for carbon fiber conductors has been developed. Through analysis of ACCC's material properties, the tool's rated design load and key technical parameters were determined. Validated by tensile testing and field applications, conductor lifter demonstrates advantages of simple operation, enhanced safety, time/labor efficiency, and has successfully resolved the live replacement challenge for insulators on carbon fiber transmission lines. Its deployment reduces economic losses from power outages and improves the reliability of power supply.
Key words: transmission line; live-line working; aluminum conductor composite core (ACCC); conductor lifter
