Core Viewpoint - The State Grid Pinghu Power Supply Company has independently completed the installation of a fixed fall protection rail system for 110 kV lines without power interruption, marking a significant advancement in safety and operational capabilities in high-risk maintenance work [3][4]. Group 1: Safety and Operational Improvements - The implementation of the fixed fall protection rail system represents a substantial enhancement in high-altitude fall protection, creating a permanent and continuous safety channel throughout the entire process of climbing, working, and descending the tower [4]. - The new system allows workers to maintain continuous attachment without frequently changing anchor points, significantly improving both safety and operational efficiency during tower climbing tasks [4]. Group 2: Project Execution and Planning - The company developed tailored construction plans based on the characteristics of different tower structures, employing a "one tower, one plan" approach to ensure precise execution and safety [3]. - A collaborative and segmented responsibility model was adopted during the operation, clarifying roles and ensuring orderly process transitions [3]. Group 3: Technological Integration - The entire operation relied on three-dimensional simulation for task rehearsal and risk pre-control, utilizing real-time monitoring networks to dynamically sense and manage key risk points [3]. - The company has completed modifications on 62 towers across 17 lines, reinforcing the safety foundation for power grid operations and enhancing regional power supply reliability [4].
