Core Viewpoint - State Grid Henan Electric Power has successfully applied two innovative technologies in the construction of the Xuchang South 500 kV substation project, addressing major challenges in power line crossing construction and providing a model for complex power grid construction nationwide [1][2]. Group 1: Innovative Technologies - The "Yonglin Combination" special crossbeam net sealing technology involves installing removable auxiliary crossbeams on towers to suspend the bearing cable during construction, which can be removed afterward to restore the tower's original appearance [1]. - The heavy-duty drone joint suspension technology utilizes two octocopters to collaboratively lift and adjust the bearing cable, ensuring safety distance from the line and the object being crossed throughout the operation [1]. Group 2: Advantages and Economic Impact - Both new technologies significantly reduce land occupation, enhance reliability, and improve economic efficiency, shortening net sealing time by 40% and lowering costs by 40% compared to traditional methods [2]. - These technologies are particularly suitable for construction scenarios with complex terrain, restricted traffic, and difficulties in power outages, laying a solid foundation for non-power outage crossing construction in the Henan power grid [2].
