66kv Modular Composite Material Emergency Repair Tower Simulation of Mechanical Performance and Experimental Study of Components

Abstract This paper details the design and performance evaluation of a 66kV modular insulated tower, aimed at enhancing the resilience and operational flexibility of power systems in extreme environments. The tower employs advanced composite materials, providing excellent mechanical strength. The design addresses various conditions, including line breaks, high wind speeds, and icing scenarios. Finite element analysis conducted using ANSYS software showed that the safety factor for the pole body is 2.14, indicating that the designed tower meets the safety factor requirements. Additionally, its excellent mechanical properties have been verified through mechanical property tests. The modular design facilitates rapid assembly and disassembly as needed across different contexts, significantly improving the efficiency and flexibility of emergency repair work, thus offering considerable benefits for power grid upgrades, maintenance, and disaster recovery. In summary, the 66kV modular insulated tower demonstrates its broad potential applications within modern power systems. The results of this study provide valuable references for power system design, especially in seeking more efficient and adaptable transmission repair solutions.
